Zielsetzung hier beschriebenen Digital Sound Slaves ist es, einem Mikrocontroller-gesteuertem Kleinstsystem eine …Stimme“ zu geben und so eine zeitgemäße Benutzerführung auch in kleinen Anwendungen zuermöglichen.Dies ist zumeist mit Board-Mitteln eines MC-Systems nicht, oder nur mitgroßem Aufwand möglich. Häufig konsumiert diese Funktion dann den Großteil der Systemressourcen, wobei die Sound-Wiedergabe meistens ein Kompromiss bleibt.Die Entwicklung des Digital Sound Slaves soll die angesprochenen Nachteile in einfacher Weise beheben.Das Digital Sound Slave besitzt folgende Eigenschaften:•Einfache Programmierung•Wiedergabe von beliebigen WAV-Files und damit gut verständliche Sprachwiedergabe•Einfacher elektrischer Anschluss des Digital Sound Slaves an das MC-System•Einfache Nutzung des Digital Sound Slaves mittels API•Minimale Systembelastung durch die Sound-Wiedergabe•Direkter Betrieb eines Kleinlautsprechers bis 1 WAbbildung 1: Modul-Vorderseite Abbildung 2: Modul-RückseiteAbbildung 3: Modul mit externem LautsprecherAbbildung 4: Beispiel mit PCB-Lautsprecher und Horn (Unterseite)Das Digital Sound Slave ist in der Abbildung mit einem SMD-Miniatur-Lautsprecher mit Horn bestückt. Das Modul verfügt aber auch über einen externen Anschluss für einen Lautsprecher der Wahl.Abbildung 5: Beispiel mit PCB-Lautsprecher und Horn (Oberseite)HardwareDer Analogkreis des Moduls wird in der Regel mit 5 V versorgt um die nominale Leistung von einem Watt zu erreichen. Der Digitalteil des Moduls wird mit 3,3 V direkt versorgt. Soll das komplette Modul mit 3,3 V versorgt werden, so ist der Löt-Jumper entsprechend zu setzen.Schaltplan und LayoutAbbildung 6: SchaltplanAbbildung 7: LayoutArchitekturDas Digital Sound Slave verwendet einen integrierten Signalprozessor ISD2360 (ISD-Chip-Corder) von Fa. Nuvoton zur Signalerzeugung. Dieser Chip kann ohne Verstärker direkt einen 1W Kleinlautsprecher (bei 5V) an den Chipausgängen SPK+ und SPK- betreiben. Ferner ist der Chip mit 3,3-5V (max. 1 W) zu versorgen.Als Interface dienen entweder 5 GPIO Pins, mit denen Voice-Files getriggert (steigende/fallende Flanken) werden können, oder der Chip wird über SPI direkt angesteuert. Die zweite Möglichkeit bietet einen sehr flexiblen Einsatz.Dabei können in dem 2Mbit großen Speicher auf dem Chip ca. 64 Sekunden Voice-Prompts hinterlegt werden.Ein direktes …streamen“ über SPI zur direkten Ausgabe ist ebenfalls möglich. Dies setzt aber große Speicherressourcen in dem Mikrocontroller-System voraus. Dabei verwaltet der Chip-Corder bis zu 3 unabhängige Sound-Kanäle die bei Bedarf überlagert simultan ausgegeben werden.Die Ausgaben werden entweder direkt über Voice-Prompts (Wave-File) aus dem internen Chip-Speicher, oder per SPI-Streaming bedient.Dabei kennt der Chip Voice-Prompts, welche die ultimative Sound-Ressource darstellt und Voice-Macros, mit deren Hilfe Voice-Prompts aneinander gehängt werden können (Script-Sprache z.B. ganze Sätze aus Wortschnipsel). Voice-Macros können neben linearen Abrufen von Voice-Prompts auch Wiederholschleifen oder prozedurale Schleifen abarbeiten und sind damitmächtige Werkzeuge in der Wiedergabetechnik.Der ISD-Chip-Corder funktioniert im Stand-alone Modus, als auch im SPI-Modus (simultan). Der Chip muss aber, bevor er ins Zielsystem eingebracht wird, entsprechend programmiert werden. Dies findet mit der Software …Voice Prompt Editor“ von Nuvoton statt. Diese kann von der Nuvoton-Web-Seite heruntergeladen werden.Für weiterführende Informationen siehe [ISD2360 DESIGN GUIDE].ProgrammierungUm den Einstieg möglichst einfach zu gestalten, ist das Digital Sound Slave bereits mit einem Satz Voice-Prompts und Voice-Macros geladen und kann direkt verwendet werden.Soll dieser Inhalt verändert oder durch einen anderen ersetzt werden, ist das mit der oben erwähnten Software möglich.Integrierte Voice-PromptsVoice-Prompts sind komprimierte und für den ISD2360 aufbereitete Wave-Files. Sie stellen die ultimative Sound-Quelle dar und nehmen erfahrungsgemäß den größten Platz im internen Speicher des ISD2360 ein. Daher muss die Auswahl der zu integrierenden Voice-Prompts mit Bedacht getroffen werden.Allgemein ist eine Sample-Rate von 8kHz bei 16 Bit/sample und Mono zuwählen.Die folgenden Voice-Prompts sind im Auslieferungszustand programmiert.VP Westminster – BigBenDiese Tonaufnahme des Westminster-Glockenspiels wurden als kompletter Satz aller Spielmuster im Internet zum lizenzfreien Download angeboten. Diese wurden dann in die einzelnen Glocken zerlegt und hier nach Glocken geordnet abgespeichert.Dabei gibt es 2 Arten von Samples:1.Anschlag der Glocke mit der Dauer y bis zum nächsten Glockenschlaginnerhalb eines Blocks.2.Anschlag und Ausklingen der Glocke mit der Dauer y + x bis Blockende Siehe auch “Integrierte Voice-Macros“Mit diesem Satz von Voice Prompts kann das komplette Glockenspiel zusammengesetzt werdenIntegrierte Voice-MacrosVoice-Macros sind Skripte, mit denen man Voice-Prompts zusammenhängen kann, so dass komplexe Klangaggregate entstehen.

Dieses kann im Download-Bereich heruntergeladen werden.Der GPIO 5 Anschluss löst bei Betätigung (Verbindung zu GND) ein Test-Macro aus. Dieses demonstriert das zusammensetzen von Wort-Schnipsel zu vollwertige Sätze und gibt auch den kompletten Voice-Prompt-Inhalt des internen Speichers aus. Dadurch ist auch im Stand-alone-Betrieb der programmierte Inhalt des Chips leicht zu prüfen.AbbildungsverzeichnisAbbildung 1: Modul-Vorderseite (3)Abbildung 2: Modul-Rückseite (3)Abbildung 3: Modul mit externem Lautsprecher (4)Abbildung 4: Beispiel mit PCB-Lautsprecher und Horn (Unterseite) (4)Abbildung 5: Beispiel mit PCB-Lautsprecher und Horn (Oberseite) (4)Abbildung 6: Schaltplan (5)Abbildung 7: Layout (6)Literaturverzeichnis[ISD2360 DATA SHEET]ISD2360 Data SheetRev. 1.00, 15.01.2020Nuvoton[ISD2360 DESIGN GUIDE]ISD2360 Design GuideRev. 1.15, 03.08.2016Nuvoton[ISD2360 DEMO USERM]ISD-DEMO2360 User ManualRev. 1.1, 13.04.2016Nuvoton[ISD2360 ESMINIUSB UM]ISD-ES_MINI_USB User ManualRev. 1.0, 18.02.2016Nuvoton[ISD2360 WIN IDE]ISD-VPE2360 for Windows7 64bitIDE-Software...

Wireless microphones transduce the waveform of audio entering the microphone into an electrical signal and transmit that signal to a tuner over radio waves. In this event, it is an analog wireless system that processes the audio signal as it is in the waveform. On the other hand, it is a digital wireless system that digitally processes the audio signal.More specifically, in the digital system, after an analog signal (waveform) is transduced into a digital signal (asignal simplified by binary numbers 0 and 1) and transmitted by radio, the digital signal is demodulated into an analog signal and then the audio is output. By digitally processing and simplifying the audioinformation to be transmitted, the system can have a variety of advantages, including strong immunity to noise and maintenance of clear sound.Let’s have a look at the “D/U ratio” of analog-to-digital wireless systems. The D/U ratio refers to the ratio of the desired (D) signal to the undesired (U) signal (unit: dB). The desired signal represents the level of that signal, while the undesired signal represents the level of signal interference, otherwise called noise. The D/U ratio decreases as the undesired signal increases. The D/U ratio can be considered to be a value necessary to maintaining clear sound in a wireless system. If a comparison is made of the necessary D/U ratio between analog and digital wireless systems, it is 40dB for analog systems and 20dB for digital systems. From this, it can be seen that the digital wireless system has an edge over the analog wireless system by 20dB in terms of necessary D/U ratio, indicating that the digital system can maintain clear sound in circumstances where a lot of undesired signals are present.» How the Digital Wireless System Works» Why are digital wireless systems resistant to interference signals?Analog System Digital SystemDigital signal processing of analog audioDemodulation of digital to audible analog signal(analog)“H el l o ”Audio (analog)12Wireless receiverBroadcast122Not only can the digital wireless system reduce the influence of noise, it can also maintain clear sound quality by means of digital processing. In addition to this, there are various advantages unique to the digital wireless system.» Use of Multiple Channels in the Same AreaSince the wireless microphone makes itself a source of noise, when using multiple channels in the same area, channels must be arranged to avoid radio interference due to intermodulation interference. In the case of the analog wireless system, the most efficient channel arrangement is as shown in the [Analog] figure below if the intermodulation interference of radio waves is taken into consideration. In this arrangement, the simultaneous use of 6 channels is all it can handle per 4 MHz band.* This is an example.In the digital wireless system, however, since one of its features is being immune to the influence of noise, even when the intermodulation interference occurs, individual channels are less likely to be affected by it. As a result, equal-interval channel arrangements such as shown in the [Digital] figure below becomes possible, allowing up to 10 channels to be used simultaneously per 4 MHz band.* This is an example.» Interference Noise MutingAnalog systems are prone to generation of strange noises when exposed to radio interference. Conversely, radio interference is muted in digital systems, so strange noises are not produced.» Reuse of the Same ChannelAnother advantage of the digital wireless system is that simultaneous use of multiple microphones on the same frequency in the same area can be realized more easily because of its immunity to radio interference and noise.In the case of analog systems, the distance between microphones should be at least 100 meters when using the same frequency channel in the same area to ensure 40 dB of D/U ratio. However, in the case of digital systems, the distance can be reduced to 30 - 40 m*, making it easier to cope with even a building (area) with multiple rooms that require multiple microphones.*This can change depending on antenna mounting conditions or room conditions, such as the thickness or material of walls.Area and RoomRoomRoom» Improved SecurityConventional analog wireless systems transmit their audio signals through FM modulation. With this method, it is possible that communications could be intercepted by general broadband receivers (FM radio, etc.), causing much anxiety in terms of security. On the other hand, with digital systems, since the audio is transmitted through digital modulation, only noise can be heard if received by a broadband receiver. This can prevent exposure of information, leading to improvements in the security of information communication.(Horizontal coverage of antennas, Page 7)the supplied antenna.the supplied antenna.(Installation of the YW-4500 Wireless antenna, Page 7)o Step (3)(Antenna distribution, Page 8, 9)1) Select an arbitrary bank from Banks 1 – 4 at the receiver.

This is necessary for ensuring optimal conditions for one antenna to receive signals when the microphone my experience the other antenna's dead spot. In other words, the shape of the room does not matter provided that the above conditions are met. On a diagram of the site, use a compass to draw two circles representing a radius of 20 – 30m with each antenna as the central point. If usage locations fall within either of the two circles, such locations can be deemed to be okay.Point 2As a guideline, the distance between the two antennas should be 3 – 18m. Although the coverage area becomes wider as the distance between antennas increases, this degrades the diversity effect, and signal interruption will become more liable to occur.If possible, locate one antenna in the direction that can be viewed from the position where the microphone is held, and the other antenna in the opposite direction (behind the microphone holder).Point 3In indoor installations, as a general guideline, install antennas at a height of 2 – 4m above the floor, lest the signal be blocked by people in the room. Keep the antennas about 30cm below the ceiling. Install the antennas so they face in the specified directions. When making protectors, use resin or timber and do not use metallic materials.• Avoid positioning antennas close to metallic objects wherever possible.• Avoid mounting antennas inside a ceiling or wall.• Select locations where the antenna can be protected from being hit and damaged by objects.• Protect the antennas against rain water.Important points for selecting the mounting position of diversity antennas are as follows:Horizontal coverage of antennas under optimal conditionsInstallation of the YW-4500 Wireless Antenna• YW-4500• WT -D5800 Rod Antenna• Using 1 - 3 channelsAntennas can be distributed without using the WD-5800 Antenna Distributor.• Simultaneous use of 4 channels• Simultaneous use of 5 – 8 channelsaudio• Simultaneous use of 9 -16 channels• Simultaneous use of 17 - 32 channelsaudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixeraudioto mixerSplit antennas into two systems and construct a system of up to 32 channels.• Frequency table which can be used with 5000 Series analog wireless systemCompatible Frequency List*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - F cannot be used when including existing analog wireless equipment in the system.Compatible Frequency List*WM-D5200/D5300, WT-D5800• Frequency table which can be used with 5000 Series analog wireless systemCompatible Frequency List*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - F cannot be used when including existing analog wireless equipment in the system.*WM-D5200/D5300, WT-D5800• Frequency table which can be used with 5000 Series analog wireless system*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - E cannot be used when including existing analog wireless equipment in the system.*WM-D5200/D5300, WT-D5800• Frequency table which can be used with 5000 Series analog wireless system*WM-D5200/D5300, WT-D5800: BANK 1 - 4WM-4200/4300/5220/5270/5320/5225/5265/5325: BANK 1– 4WT-4800/5800/5805: BANK 1– 4WM-4210/4220/4310, WT-4810/5100/5810, WTU-4800: BANK 1• When needing more channels*Banks A - E cannot be used when including existing analog wireless equipment in the system.*WM-D5200/D5300, WT-D5800When using transmitters in numbers greater than the number of simultaneously usable channels and in close proximity to each other, microphones operating on the same frequency can be used simultaneously by utilizing their digital characteristics. Note, however, that the same frequency cannot be used in the same room.1. Make channel plans1) Referring to the Frequency T able, select an arbitrary bank from A to F . 2) Scan receiver channels.• C band: Searches for channels in two banks including the currently-set bank and displays idle channels.Combinations of scanned banks are as follows: When Bank A or B is currently set a Searches for and displays idle channels in Banks A and B. When Bank C or D is currently set a Searches for and displays idle channels in Banks C and D.When Bank E or F is currently set a Searches for and displays idle channels in Banks E and F .• G band: Searches for all bank channels in the dedicated digital plan, and displays idle channels.3) Assign idle channels to multiple rooms as shown in the following examples to prevent channelsoperating on the same frequency from being too close to each other.[Example] Same floor or same location on each floor.[Example] Multiple rooms are adjacent to each other on both upper and lower floors in facilities like rental conference rooms and schools. There is a high possibility that the frequencies being used in the ‐ Keep channels using the same frequency as far away from each other as possible. If used on the same floor, keep them at least two rooms apart.‐ Set the wireless microphone’s transmission output to “L.”‐ Adjust the antenna attenuator.2. Use "Code" (recommended)This function prevents interference between channels sharing the same frequency. By performing Code settings, receivers and transmitters can be paired, muting radio signals on the same frequency that may exist in the surrounding area. Code setting is effective when the encryption function is not set.» Code setting proceduresFigure a. Even if the code is the same, if the power for both microphones is ON, radio interference will not occur. (Since the stronger radio signal takes precedence, only the microphone within the immediate area is reproduced.)Figure b. If power to either area is turned off when Figure a conditions exist, Receiver 1 may mistakenly receive MIC 2 audio. (Since the code is the same, it would be impossible to distinguish between MIC 1 and MIC 2.)Figure c. If different codes are set in Area 1 and Area 2, mistakenreception will not occur even if power to the microphone for either area is turned off. (Since microphones in both areas differ in code, audio is muted.)Code settingssolve these problems.Hold down the “SET” key for 2 seconds or more.Select “CODE” and press “SET”Select an arbitrary numberSet the same code for the transmitter to be paired.WT -D5800M E N U >C O D ES E T C O D ENOTE: Since the encryption function, which enhances security, also requires pairing of a transmitter with a receiver, code setting is unnecessary if the encryption function is used.Hold down the “SET” key for 2 seconds or more.Select ENCRYPTION from the menu Select “ON”Select P AIRING from the menu1) Enable receiver’s encryption function.2) Pair the receiver with a transmitter.Switch on the transmitter while holding down the “Encryption” setting switch.Press and hold “SET” till the “SUCCESS” is displayed.If encryption function is achieved, the“ANT A/B” indication and the lock icon lights red.If pairing is achieved, the “ANT A/B” indication lights green andthe transmitter’s “Encryption” light also lights.WT -D5800SETM E N U>H O L D T H E S E T K E YM E N U >PA I R I N GPA I RI N G P RO C E S S R E C E I V I N GPA I R I N G P RO C E S S S U C C E SSEncryption Function SettingsExposure of important information can be prevented by pairing a receiver with a transmitter by TOA’s proprietary security IDs.» Engryption setting proceduresInterference Countermeasures Order of Actions (Action Flowchart)Antenna Attenuator» Antenna Attenuator FunctionThis function decreases the antenna reception sensitivity so as to minimize reception of distant interference radio signals.•When to use this functionUse this function when radio interference or signal interruption caused by the interference of other systems intermittently occurs.Note: Since the use of an attenuator shortens the transmission distance and reduces the range of the usable area, ensure that the microphone can be used without signal interruption in the intended usage area after performing settings.The attenuator can effectively reduce interference signals if they are relatively weak. The most effective results may not be obtained when interference signals are strong (i.e. when audio interference constantly occurs).•Proper use of two attenuatorsUse either the WT -D5800 or YW-4500 attenuator to attenuate the reception sensitivity by 10dB. The WT -D5800 may be more convenient as it allows settings by hand.Since the attenuation of both the YW-4500 and WT-D5800 attenuators are added together, when wishing to attenuate reception sensitivity by at least 10dB, use both attenuators in combination.(This is a rare case, though.)UndesiredUndesiredFBS SettingIt is a function that the built-in feedback suppressor filter automatically works to suppress acoustic feedback when the feedback occurs.Use this function when increases in the receiving wireless microphone’s sound volume tend to generate acoustic feedback and reduce speech clarity or make it impossible to achieve the necessary sound volume for broadcast.» What is the feedback suppressor function?» What is the FBS built into the WT -D5800?NOTE: Acoustic feedback, or howling, is generated when sound output from a speaker reenters the microphone. Before using this function, check to see if the microphone and speaker are positioned too close to each other, or if the sound volume is louder than necessary.In circumstances where feedback is especially liable to occur, the most effective results may not be obtainable, or sound quality may vary greatly.LevelFeedback suppressor filterFrequencyFeedback frequencyHold down the “SET” key for 2 seconds or more.Select “FBS” and press “SET”WT -D5800M E N U >F B SS E T F B S 3O NEQ Setting (Recommended)This function optimizes audio characteristics for each model of handheld wireless microphone or any microphone connected to the belt-pack transmitter.Select the model number of the microphone to use, and perform settings in EQ setting mode.» What is the microphone EQ built into the WT -D5800?NOTE: This function is set to OFF by default.Set the “Microphone EQ” to OFF when the corresponding model number is not shown in the display of the EQ setting mode.Hold down the “SET” key for 2 seconds or more.OptionsWT-D5800S E T E Q P R E S E T 3E X I TS E T E Q P R E S E T 3Y P -M 5300S E T E Q P R E S E T 3W M -D 5200S E T E Q P R E S E T 3O F FS E T E Q P R E S E T 3Y P -M 5310S E T E Q P R E S E T 3W H -4000AS E T E Q P R E S E T 3W H -4000HM E N U>E Q P R E S E TOptimizing Sound Volume(1) Set the receiver’s volume control to the 2 o’clock position.For current TOA wireless receivers with the volume control located on the front panel, the 2 o’clock position (scale 7) is the volume control position that minimizes sound distortion until the maximum input sound pressure is applied to the microphone. From that position to the maximum volume position, a gain of approximately 10dB is made available as an allowance when turning up the volume.(2) Set the transmitter’s (microphone’s) sensitivity to “H” or “L ” depending on whether the volume is insufficient or noise is detected at normal sound volume, or if distortion is not noticeable when speaking in a loud voice.n to the maximum volume position, a gain of approximately 10dB is made available as an allowance when turning up the volume.(3) Adjust the input level of the amplifier or mixer to an appropriate sound volume for use under normal conditions.Microphone sensitivity can be set to "0 dB (H)" or "-10 dB (L)".TOA Corporationwww.toa.jp。
