No matter what the settings of the DSP controls, the preset is recalled when a channel is selected. You may change the DSP settings by rotating the DSP con-trols - these changes will remain active until a different channel is selected, but will not be there for later use unless they are saved. To save a new DSP preset to a channel,first make the desired DSP changes. Then press and hold the Save/Tap button for about three seconds. The Save/Tap LED will flash through three quick sequences, indicating the preset was saved. The new preset is stored for that channel and will remain in mem-ory until a new preset is stored for that channel or the factory presets are restored.We recommend making copies of page 14 of this guide for the purpose of writing down your own presets.Restoring the Factory Presets:The factory assigned DSP presets may be restored, erasing any changes you have made. Turn the amplifier off. Press and hold the Save/Tap button as you turn the amplifi-er on. The Save/Tap LED will flash through two quick sequences, indicating the factory presets have been restored.More About the Save/Tap Button:The Save/Tap button is used to set the tempo of an effect by pressing it twice within a one second time frame. The time between the two taps sets the timing of the effect. If the Save/tap button is pressed an odd number of times (once, three times, etc.), the tim-ing will default to the maximum one second time period.The Multi effects and the Delay effects may each have a different tap speed. The default “target” for the Save/Tap button is the Delay control. To select the Multi control as the tap button’s target, rotate the Multi control. The Save/Tap tempo function will auto-matically revert back to the Delay control 16 seconds after the Multi control is rotated, or when the tap speed was last changed for the Multi effect.NOTE: In most cases, it is usually more pleasing to the ear to set a slower tap speed for the HI effects and a faster tap speed for the LO effects.MULTIDSPDELAYREVERB SAVE / TAPMULTIDSPDELAYREVERB SAVE / TAPMULTIDSPDELAYREVERBSAVE / TAP3 SECONDSUsing the Footswitch for More Presets:The Crate three-button footswitch supplied with the VTX65 allows access to an addi-tional DSP preset for each channel of the amplifier. When the footswitch is connected to the amplifier as shown below, the “original” DSP presets are active for each channel when the #3 footswitch LED is illuminated. These are referred to as “DSP Bank ‘A’.”When the #3 button is switched and the LED is out, a second DSP preset may be stored and recalled for each channel - “DSP Bank ‘B’.”NOTE: DSP Bank “B” presets are only accessible when the footswitch is connected to the amplifier. When the footswitch is not connected, only DSP Bank “A”is accessable.Switch #1: LED on = SOLO CH. LED off = RHTYHM CH. Only when Switch #2 is activated (LED lit)!Switch #2:LED on = SOLO/RHYTHM CH.LED off = CLEANCH.Switch #3:LED on = DSPBANK "A"LED off = DSPBANK "B"321910DSP Factory Presets:Factory Preset 1: Clean w/Chorus, Delay,ReverbMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPThe VTX65 Factory Presets for the DSP section are as follows:11DSP Factory Presets:Factory Preset 4: Clean w/ReverbFactory Preset 6: Solo w/ReverbMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPThe VTX65 Factory Presets for the DSP section are as follows:12VOLUME GAINLOWMIDHIGH LEVELLOW RHYTHMMULTIDSPDELAYREVERBVOLUME GAINLOWMIDHIGH LEVELLOW RHYTHMMULTIDSPDELAYREVERBVOLUME GAINLOWMIDHIGH LEVELLOW RHYTHMMULTIDSPDELAYREVERB13VOLUME GAINLOWMIDHIGH LEVELLOW RHYTHMMULTIDSPDELAYREVERBVOLUME GAINLOWMIDHIGH LEVELLOW RHYTHMMULTIDSPDELAYREVERBVOLUME GAINLOWMIDHIGH LEVELLOW RHYTHMMULTIDSPDELAYREVERB14DSP “Fill in the Blanks ”(User Settings):MULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPMULTIDSPCHORUS FLANGEPHASERVIB OT RDELAYEFXECHO SINGLE TAPEREVERBSAVE / TAPUser Preset: _________________________________CHANNEL:BANK:SOLO RHYTHM CLEAN "A""B"CHANNEL:BANK:SOLO RHYTHM CLEAN "A""B"CHANNEL:BANK:SOLO RHYTHM CLEAN "A""B"User Preset: _________________________________User Preset: _________________________________Copy this page to fill in your own DSP Presets!15System Block Diagram:INPUTBUFFERMIX AMPCLEANDAMPING CIRCUITPOWER AMPSPEAKERSPEAKERINSERTSWITCHING RHYTHMSOLORHYTHMTUNERA BC D EF GVTX65TECHNICAL SPECIFICATIONS:Output Power Rating65W RMS @5% THD, 8Ω, 120 VACSpeaker Size and Rating(1) Custom Design 12”, 8ΩInput Impedance470kΩTotal System Gain Solo Ch110dB, all controls @10Rhythm Ch88dB, all controls @10Clean Ch58dB, all controls @10CD Input29dBMaximum Input Signal Accepted7 volts peak-to-peakSolo Channel Shape Control Proprietary CircuitRhythm Channel Low Control20dB range @ 80HzMid Control15dB range @ 1kHzHigh Control20dB range @ 10kHzClean Channel Low Control36dB range @ 80HzMid Control15dB range @ 800HzHigh Control40dB range @ 10kHzPower Requirements120 VAC, 60Hz, 90VA100/115VAC, 50/60Hz, 90VA;230VAC, 50/60Hz, 90VASize and Weight19-1/4” H x 21” W x 10-1/4”D, 34 lbs.The VTX65 is covered with a durable Tolex material: wipe it clean with a lint-free cloth.Never spray cleaning agents onto the cabinet.

Functional DescriptionFigure4.Si4844-B Functional Block Diagram4.1. OverviewThe Si4844-B is the analog-tuned digital-display digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. Working with an external MCU with LCD/LED driver, Si4844-B can output the AM/FM/SW frequencies, band, Bass/Treble and stereo/mono information to display on LCD/LED, while using a simple potentiometer at the front end for analog-tune. Leveraging Skyworks' proven and patented digital low intermediate frequency (low-IF) receiver architecture, the Si4844-B delivers superior RF performance and interference rejection in AM, FM and SW bands. The Si4844-B is pin-to-pin compatible with the current Si484x-A tuning. The Si4844-B shares the advanced features of the Si484x-A and can support a wider range of FM and SW bands. It also supports China TV channels and audio reception in the FM band. The superior control algorithm integrated in Si4844-B provides an easy and reliable control interface while eliminating all the manually tuned external components used in traditional solutions.Like other successful audio products from Skyworks, Si4844-B offers unmatched integration and PCB space savings with minimum external components and small board area on a single side PCB. The high integration and complete system production test simplifies design-in, increases system quality, and improves manufacturability. The receiver has very low power consumption, runs off two AAA batteries, and delivers the performance benefits of high performance digital radio experience with digital display to the legacy analog-tuned radio market.The Si4844-B provides good flexibility in using the chip. The frequency range of FM/AM/SW bands, mono/stereo threshold, de-emphasis value, AM tuning step, AM soft mute level/rate, and Bass/Treble can be either configured by the MCU or by using external hardware to make a selection. The reference clock of the FM tuner can be provided either by the crystal or by the host MCU within tolerance.Si4844-B also has flexibility in selecting bands and configuring band properties, enabling masked Host MCU for multiple projects, and reducing the cost of development. Four tuning preferences are available tomeet different tuning preference requirements.4.2. FM ReceiverThe Si4844-B integrates a low noise amplifier(LNA) supporting the worldwide FM broadcast band (64to 109MHz) and the TV audio stations within the fre quency range in China are also supported. The FM band can also be configured to be a wider range such as 64–108 MHz in one band.Pre-emphasis and de-emphasis is a technique used by FM broadcasters to improve the signal-to-noise ratio of FM receivers by reducing the effects of high frequency interference and noise. When the FM signal is transmitted, a pre-emphasis filter is applied to accentuate the high audio frequencies. All FM receivers incorporate a de-emphasis filter which attenuates high frequencies to restore a flat frequency response. Two time constants are used in various regions. The de-emphasis time constant can be chosen to be 50 or 75μs. Refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines.”The Si4844-B also has advanced stereo blending that employs adaptive noise suppression. As a signal quality degrades, the Si4844-B gradually combines the stereo left and right audio channels to a mono audio signal to maintain optimum sound fidelity under varying reception conditions. The Si4844-B can output a stereo signal to MCU with LCD/LED driver to display on the LCD/LED so that the user can easily discern the signal quality.The stereo on signal is defined using both RSSI and the Left and Right separation levels as these two specifications are the primary factors for stereo listening. The criteria can be set between two conditions: the Left and Right channels are separated by more than 6dB with RSSI at >20dB or Left and Right channels are separated by more than 12dB with RSSI at >28dB. The selection can be set up using different values of the external resistor or configured by the host MCU. Refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines.”The user can also refer to the “AN610: Si48xx ATDD Programming Guide” for those who want to configure the value by host MCU.4.3. AM ReceiverThe highly integrated Si4844-B supports worldwide AM band reception from 504 to 1750kHz with five sub-bands using a digital low-IF architecture with a minimum number of external components and no manual alignment required. This patented architecture allows for high-precision filtering, offering excellent selectivity and SNR with minimum variation across the AM band. Similar to the FM receiver, the Si4844-B optimizes sensitivity and rejection of strong interferers, allowing better reception of weak stations.To offer maximum flexibility, the receiver supports a wide range of ferrite loop sticks from 180–450μH. An air loop antenna is supported by using a transformer to increase the effective inductance from the air loop. Using a 1:5 turn ratio inductor, the inductance is increased by 25 times and easily supports all typical AM air loop antennas, which generally vary between 10 and 20μH.A 9, 10kHz tuning step can be chosen by the external resistor or host MCU according to the different regions, and AM soft mute level can be programmed by the host MCU to have different tuning experiences. One of the AM bands can be configured as a universal AM band that simultaneously supports 9kHz and 10kHz channel spaces for all regional AM standards worldwide. Refer to “AN610: Si48xx ATDD Programming Guide” and “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”for more details.4.4. SW ReceiverThe Si4844-B supports short wave band receptions from 2.3 to 28.5MHz in 5kHz step size increments. It can also be configured to have a wide SW band that can be used in SW radio with 1 or 2 SW banks. Si4844-B supports extensive short wave features such as minimal discrete components and no factory adjustments. The Si4844 supports using the FM antenna to capture short wave signals. Refer to “AN610: Si48xx ATDD Programming Guide”and “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”for more details.4.5. Frequency TuningA valid channel can be found by tuning the potentiometer that is connected to the TUNE1 and TUNE2 pin of the Si4844-B chip.To offer easy tuning, the Si4844-B also outputs the tuned information to the MCU with LCD/LED driver to display. It will light up the icon on display if the RF signal quality passes a certain threshold when tuned to a valid station. Multiple tuning preferences are available. The user can choose to have the best performance (volume, stereo/mono effect) only at the exact channel, or the best performance in a larger range. Refer to "AN610: Si48xx ATDD Programming Guide" for more details. 4.6. Band SelectThe Si4844-B supports worldwide AM band with five sub-bands, US/Europe/Japan/China FM band with five sub-bands, and SW band with 16 sub-bands. Si4844-B provides the flexibility to configure the band and band properties at either the MCU side or the Tuner side, enabling masked MCU for multiple projects. For details on band selection, refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”and "AN610: Si48xx ATDD Programming Guide".4.7. Bass and TrebleThe Si4844-B further supports Bass/Treble tone control for superior sound quality. The Si4844-B can be set to be default normal, or programmed by the host MCU I2C-compatible 2-wire mode. FM has nine levels Bass/Treble effect and AM/SW has seven levels Bass/Treble effect. For further configuration details, refer to "AN610: Si48xx ATDD Programming Guide." 4.8. Volume ControlThe Si4844-B not only allows users to use the traditional PVR wheel volume control through an external speaker amplifier, it also supports digital volume control programmed by the host MCU. Si4844-B can be programmed to be Bass/Treble mode only or digital volume mode only; it can also be programmed to have the digital volume coexist with Bass/Treble in two modes. Refer to "AN610: Si48xx ATDD Programming Guide" and “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines” for more details.4.9. Stereo Audio ProcessingThe output of the FM demodulator is a stereo multiplexed (MPX) signal. The MPX standard was developed in 1961, and is used worldwide. Today's MPX signal format consists of left + right (L+R) audio, left – right (L–R) audio, a 19kHz pilot tone.Figure5.MPX Signal Spectrum4.9.1. Stereo DecoderThe Si4844-B's integrated stereo decoder automatically decodes the MPX signal using DSP techniques. The 0 to 15kHz (L+R) signal is the mono output of the FM tuner. Stereo is generated from the (L+R), (L–R), and a 19kHz pilot tone. The pilot tone is used as a reference to recover the (L–R) signal. Output left and right channels are obtained by adding and subtracting the (L+R) and (L–R) signals respectively.4.9.2. Stereo-Mono BlendingAdaptive noise suppression is employed to gradually combine the stereo left and right audio channels to a mono (L+R) audio signal as the signal quality degrades to maintain optimum sound fidelity under varying reception conditions. Three metrics, received signal strength indicator (RSSI), signal-to-noise ratio (SNR), and multipath interference, are monitored simultaneously in forcing a blend from stereo to mono. The metric which reflects the minimum signal quality takes precedence and the signal is blended appropriately.All three metrics have programmable stereo/mono thresholds and attack/release rates. If a metric falls below its mono threshold, the signal is blended from stereo to full mono. If all metrics are above their respective stereo thresholds, then no action is taken to blend the signal. If a metric falls between its mono and stereo thresholds, then the signal is blended to the level proportional to the metric’s value between its mono and stereo thresholds, with an associated attack and release rate.0575338231915Frequency (kHz)ModulationLevel4.10. Stereo DACHigh-fidelity stereo digital-to-analog converters (DACs) drive analog audio signals onto the LOUT and ROUT pins. The audio output may be muted.4.11. Soft MuteThe soft mute feature is available to attenuate the audio outputs and minimize audible noise in very weak signal conditions. An advanced algorithm is implemented to get a better analog tuning experience. The soft mute feature is triggered by the SNR metric. The SNR threshold for activating soft mute is programmable, as are soft mute attenuation levels and attack and decay rates.4.12. Reference ClockThe Si4844-B supports programmable RCLK input (to XTALI pin) with the spec listed in Table7. It can be shared with the host MCU to save extra crystal.An onboard crystal oscillator is available to generate the 32.768kHz reference when an external crystal and load capacitors are provided. Refer to "AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines" for more details.4.13. Reset, Powerup, and Powerdown Setting the RSTB pin low will disable analog and digital circuitry, reset the registers to their default settings, and disable the bus. Setting the RSTB pin high will bring the device out of reset.Figure1 shows typical reset, startup, and shutdown timings for the Si4844-B. RSTB must be held low (asserted) during any power supply transitions and kept asserted as specified in Figure1 after the power supplies are ramped up and stable. Failure to assert RSTB as indicated here may cause the device to malfunction and may result in permanent device damage.A powerdown mode is available to reduce power consumption when the part is idle. Putting the device in powerdown mode will disable analog and digital circuitry while keeping the bus active.4.14. Memorizing StatusThe Si4844-B provides the feature to memorize status from the last power down with a simple design on PCB, including frequency of the FM/AM/SW station. Refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”for details.4.15. Programming with CommandsTo ease development time and offer maximum customization, the Si4844-B provides a simple yet powerful software interface to program the receiver. The device is programmed using commands, arguments, properties, and responses.To perform an action, the user writes a command byte and associated arguments, causing the chip to execute the given command. Commands control an action such as powerup the device, shut down the device, or get the current tuned frequency. Arguments are specific to a given command and are used to modify the command. Properties are a special command argument used to modify the default chip operation and are generally configured immediately after powerup.

All controls, switches and connectors will be discussed in detail.2.1 CHANNEL INPUTMICEach mono input channel o ers a balanced microphone input via the XLR connector and also features switchable +48/+15 V phantom power supply for condenser microphones. The preamps provide undistort-ed and noise-free gain as is typically known only from costly outboard preamps.• Please mute your playback system before you activate the phantom power supply to prevent switch -on thumps being directed to your loud speakers.1. [MIC/LINE] Mono Input: Connect the microphone, musical instrument or audio device (CD player and so on) to the device. The sockets are supports both XLR and UNBALANCED 1/4" PLUG.2. [+48V PHANTOM] Button/LED: When the button is turned ON, the LED light is on, provide DC+48V phantom power to XLR plug on MIC/LINE mono input. Please turn ON this button when using the condenser microphone which is powered by a phantom power.3. [PAD] button: It will attenuate the sound input to the device when turned ON. You can turn on the switch if you hear the distortion or [PEAK]LED indicator light is on.4. [GAIN] Controller: Determines the basic volume of each channel, adjust for maximum volume performance. [PEAK] LED indicator light indicates the volume is too loud.5. [HIGH] Treble tone controller: Adjust the controller to enhance or attenuate for 15dB at 12KHz.6. [MID] Alto tone controller: Adjust the controller to enhance or attenuate for 15dB at 2.5KHz.7. [LOW] Bass tone controller: Adjust the controller to enhance or attenuate for 15dB at 80Hz.8. [FX] Controller: Adjust the signal level from the channel to the reverberation line. Please note, the single level will vary with the di erent setting of the channelattenuator. If using the stereo channel, will mix the signals from L and R channels, then, send it to reverberation line.9. [PEAK] LED indicator light: When the volume of input signal or volume after adjusting equalizer is too high, the LED indicator light will keep ashing, please rotate the[GAIN] CONTROLLER counterclockwise to turn down the volume.10. [LEVEL]:Controller ,adjust to balance the volume of each channels.6LINEEach mono input also features a balanced line input on a 1/4" connector. Unbalanced devices (mono jacks) can also be connected to these inputs.• Please remember that you can only use either the microphone or the line input of a channel at any one time. You can never use both simultaneously!GAINUse the GAIN control to adjust the input gain. This control should always be turned fully counterclockwise whenever you connect or disconnect a signal source to one of the inputs.FXFX sends (or AUX sends) enable you to feed signals via a variable control from one or more channels and sum these signals to a bus. The bus appears at the console’s FX send output and can be fed from there to an external e ects device. The return from the e ects unit is then brought back into the console on the aux return connectors or normal channel inputs. Each FX send is mono and features up to +15 dB gain.As the name suggests, the FX sends of the mixing consoles are intended to drive e ects devices (reverb, delay, etc) and are therefore con gured post-fader. This means that the mix between dry signal and e ect remains at the level determined by the channel’s aux send, irrespective of the channel fader setting. If this were not the case, the e ects signal of the channel would remain audible even when the level knob is lowered to -∞.MAIN CONTROL1. [PROGRAM] Controller: Select from 16 kinds of internal digital e ects, provides the same signal to L and R stereo.2. [REPEAT] Echo controller of internal e ects: Adjust to achieve the desired state of internal echo signal.3. [FX LEVEL] E ects return level controller: Adjust the volume of e ect.4.
