DPA d vice MMA-A 数字音频接口用户手册说明书

User’s ManualThe d:vice™ MMA-A Digital Audio Interface is a high-quality dual-channel microphone preamplifier and A/D converter. It allows you to capture crystal-clear audio via your favorite recording / broadcasting apps. The d:vice™ can be used with most DPA microphones.C a b l e l e n g t h : 30 c m (11.8 i n )Two cables are supplied with the d:vice™ MMA-A: One Micro USB-B to iOS (Lightning)and one Micro USB-B to PC / Mac (USB-A).C a b l e l e n g t h : 100 c m (39.4 i n )Getting startedConnect your DPA microphone(s) to the MicroDot input(s) on the d:vice™, denoted I and II. (If only one mic is connected to either input, the signal will be interpreted as MONO and automatically sent to both output I and II.)Download the d:vice™ AppDownload and install the d:vice™ App from the Apple App Store.Please note that the d:vice™ willwork with most 3rd-party apps andtherefore can be used in varioussituations including live broadcasts, aswell as audio and video recordings.The d:vice™ MMA-A can be used right out of the box but to take full advantage of it, please refer to these instructions to get started using the d:vice™ App.GAINUse the GAIN slider to adjust input levels. Slide to the right to increase amplification, to the left to decrease. Make sure to keep an eye on the level meters when you are adjusting gain. The meters should stay in the green and yellow areas. FILTERThe FILTER button (low cut / high pass) cuts out unwanted, low-end frequencies (rumble) that can decrease the intelligibility of your recorded audio. In most cases we suggest using the FILTER button and if, for example, you are recording outside near a road with traffic, this setting is essential.MONITORUse the MON button to send audio to your headphones so you can hear what you are recording. Please note that a headphone must be connected to the iOS device, otherwise the button will not activate and you’ll be prompted to connect a headset. If the headset includes a microphone it must be connected prior to connecting the d:vice™ via the Lightning connector. This is due to the iOS ‘last entry active’ nature of operation. (We recommend using a wireless headset when using an iPhone 7.)LOCKUse the LOCK button to block 3rd party apps from controlling gain. G ain settings can be controlled and saved on the d:vice™ for use in your favorite recording / broadcasting apps. The lock button also controls the setting of the low cut / high pass filter. Saved locked settings are automatically activated the next time you connect to the d:vice™.MONOIf only one microphone is connected to either input I or II, MONO is chosen automatically. The mic input will be routed to both left and right output. Only one GAIN slider and FILTER button will be available in this mode.STEREOUse STEREO when you need to capture sound sources in stereo. Both microphones are controlled with one GAIN slider. Example: Ambiance sounds can be recorded in stereo using two mics that have the same sensitivity.Important: When using STEREO you must use two mics that are optimized for stereo recording, for instance the specially-selected d:screet™ 4060 pair included in the d:vice™ Kit VIDMK-4060-S.Other available kits include: SMK4060, ST4006*, ST4011*, ST2006*, ST2011** Must be used with DPA MMP-G amplifiers for connection to MicroDot.DUALUse DUAL when the gain must be set individually for input I and II (for example, with two different microphone types or in situations where two people with different voice levels are to be recorded). The FILTER buttons are also individual in this situation.PRESETSPresets store your preferred settings for specific microphone(s) and make your set up easier. After choosing your settings, create the preset by pushing the numbered preset button of your choice for three seconds. The next time you plug in the same mics, push your preset button and you are ready to go – no adjustmentsnecessary.Microphone placement and usagePlease refer to the manual(s) for the specific microphone included within the package.For use with PC / MacConnect the d:vice™ MMA-A to the USB input on your PC / Mac. The d:vice™ will now work as a normal external soundcard and you can use your regular programs to record or broadcast the audiofrom the connected microphones.CleaningThe black surface of the d:vice™ is fairly scratch resistant, but is sensitive to detergents. Avoid using solvents (such as: gasoline, acetone, alcohol, turpentine, etc) for cleaning purposes. A damp clothwith warm water is recommended.Made foriPhone 7 Plus, iPhone 7, iPhone 6s, iPhone 6, iPhone 5, iPad Pro (12.9-inch), iPad Air, iPad Air 2, iPad mini 4, iPod touch (6th gen).Compatible with Mac / PC / iOS RequirementsiOS version: 10 or laterConnection / Power: Lightning & USB 2.0SpecificationsNoise floor-114 dBFS, A-weightedFrequency range20-22 kHz ±0.2 dB (Fs = 48 kHz)20-40 kHz ±0.2 dB (Fs = 96 kHz)T otal harmonic distortion (THD) THD < -100 dB, 0.001% @ 1 kHz @ -10 dBFs Dynamic rangeTyp. 114 dBFull Scale Output1 Vrms @ 0 dB GainSupported sample rates44.1, 48 (default), 88.2, 96 kHzSample rates can be set by 3rd-party app Resolution24 bitFilter (low cut / high pass)2.

Be sure to carefully read and understand the instructions before attempting to install these speakers.2. For safety, disconnect the negative lead from the battery prior to beginning the installation.3. For easier assembly, we suggest you run all wires prior to mounting your speakers in place.4. Use high quality connectors for a reliable installation and to minimize signal or power loss.5. Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle. If installation in a boat, take care not to cut or drill through the main hull.6. Never run wires underneath the vehicle. Running the wires inside the vehicle or hull area provides the best protection.7. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall.MountingMid-Bass1. Determine where the speakers will be mounted. Ensure an area large enough for the speaker to mount evenly. Be sure that the mounting location is deep enough for the speaker to fit; if mounting in a door, operate all functions (windows, locks, etc.) through their entire operating range to ensure there is no obstruction.2. Refer to the specification chart to determine the proper diameter hole to cut for your speaker model. Cutting and mounting templates can be found at .3. Mark the locations for the mounting screws. Drill the holes with a 1/8” bit.4. Feed the speaker wires through the cutout and connect to the speaker terminals. Be sure to observe proper polarity when connecting the wires. The speaker’s positive terminal is indicated with a “+”. 6. Tighten the screws until the speaker is snug in place to prevent rattling. Do not over tighten the screws.Tweeter - Discreet Dual Clamp (DDC™)1. Determine where the speakers will be mounted. Ensure an area large enough for the speaker to mount evenly. Be sure that the mounting location is deep enough for the speaker to fit; if mounting in a door, operate all functions (windows, locks, etc.) through their entire operating range to ensure there is no obstruction.2. Mark the location for the mounting hole. Drill the hole with a standard 1.75 inch (45mm) hole saw.3. With a single center screw secure the inner cup from the front of the door panel to the outer cup from back of the door panel. Tighten the screw until balanced pressure is applied to both faces of the mounting surface. 4. Feed the speaker wires through the cutout and connect to the speaker terminals. Be sure to observe proper polarity when connecting the wires. The speaker’s lead wires are indicated with a RED wire “+” and a BLACK wire “-”.5. Simply snap the tweeter into place and secure with a snap-on trim TM )InstallationStandard1.

"…quite simply they are one of the best budget speakers around."What Hi-Fi review, October 2014Diamond 220Best Stereo Speakers up to £200HeritageBritain has long been recognised as being the home of loudspeaker technology in terms of innovation and quality. Gilbert Briggs’ first loudspeaker was manufactured in 1932 through a passion for music and an ear for detail – in a sleepy little market town of Yorkshire Wharfedale was born. After winning multiple awards, his work is still much admired and respected throughout the hi-fi world today and our speakers are still driven by the same passion for music. Wharfedale’s Diamond series has a long history of achievement. The first Diamond was born in 1982 in the form of a rear ported hi-fi speaker. A combination of a 19mm dome tweeter, 120mm long throw polypropylene bass/mid driver and a simple yet highly effective crossover in a compact hi-fi speaker took the industry by storm. The speaker produced an impeccable stereo image, quickly becoming a best seller and a permanent fixture in the Wharfedale product range. Since then, every Wharfedale Diamond Series has been a best-seller.From 1982 Wharfedale Diamond has meant one thing – impeccable performance at an affordable price. Today we are pleased to bring you the latest series of loudspeakers from Wharfedale that aspires to this tradition – Diamond 200.Diamond Re-EngineeredThe Diamond 200 boasts the latest in hi-fi technology to produce a thoroughly enjoyable listening experience. Foremost in the design criteria for Diamond 200 is the ongoing research into loudspeaker driver sound quality. The Diamond Series utilises our famous woven Kevlar cone drawing influence from the flagship Jade Series. Semi-elliptical ‘break-up’ areas on the kevlar woofer smooth the response through the audible range and the cone edges are treated with a unique diamond pattern moulding.For Diamond 200 series Wharfedale’s engineers have refined and updated this design and drive unit motor systems have been redefined with more power with greater efficiency. Larger magnets for instance on the Diamond 220 create a greater sensitivity compared with previous loudspeakers.The treble unit uses a sheer fabric dome and advanced ferrite magnet system, surrounded by a carefully crafted wave guide that encourages outstanding midrange performance too.Improved Cabinet ConstructionCabinet materials have taken a leaf out of the extensive research that resulted in the advanced Jade series. Even the appearance is improved with new, lacquered front baffles and cosmetically enhanced veneers.Cabinet walls and internal bracing developed using Wharfedale’s latest ‘Virtual Speaker ’ software, with the help of Delayed Cumulative Spectral Analysis that ruthlessly reveals panel coloration in all its forms. Using this technique Wharfedale engineers updated the cabinet combining layers of particle board and MDF bonded in a unique structure to damp annoying High-Q resonances and block internal sound leakage. The effect is that the ‘noise’ from cabinet walls is buried more than 35dB below the driver output. The same computer modeling also assists in fine tuning the crossover while ensuring the speaker projects both on and off-axis for an enjoyable, room-filling experience.Tuned For Your Living RoomHundreds of hours of listening tests have resulted in refinements to the crossover systems to yield greater attack, dynamics and musical enjoyment in conjunction with the neutrality and startling realism that is a Wharfedale tradition. Although computer modeling is a valuable tool in modern loudspeaker production, it is a combination of our engineers experience and passion for music that results in such an enjoyable loudspeaker.In the final evaluation weeks are spent fine tuning the acoustic performance using a wide variety of music in Wharfedale’s five listening rooms, each of which mimics the kind of domestic environments the Diamond Series are likely to be used in. Only when the acoustic tests are deemed truly satisfying are the loudspeaker designs signed-off for production, ensuring that each speaker model fulfils its eventual owner’s dreams of musically enjoyable reproduction from Britain’s Most Famous Loudspeakers.SPECIFICATIONS:General description2-way bookshelf speaker2-way bookshelf speaker 2.5-way floorstanding speaker Enclosure type bass reflex bass reflex bass reflexTransducer complement2-way2-way 2.5-wayBass driver100mm Woven Kevlar Cone130mm Woven Kevlar Cone165mm Woven Kevlar Cone Midrange driver165mm Woven Kevlar Cone Treble driver25mm Soft Dome25mm Soft Dome25mm Soft DomeAV shield No No NoSensitivity(2.83V @ 1m)86dB86dB88dBRecommended amplifier power15-75W25-100W25-150WPeak SPL 90dB95dB102dBNominal impedance 8Ω Compatible8Ω Compatible8Ω CompatibleMinimum impedance 4.1Ω 4.1Ω 3.7ΩFrequency response (+/-3dB)68Hz - 20kHz56Hz - 20kHz40Hz - 20kHzBass extension (-6dB)58Hz45Hz37HzCrossover frequency 2.3kHz 2.2kHz 2.3kHzCabinet Volume (in litres) 3.2L7L35LDimensions (mm)Height (on plinth & spikes) 232mm315mm(938+25)mmWidth 143mm174mm196mmDepth (with terminals) (165+5)mm(227+28)mm(306+28)mmCarton size415x260x330mm495x320x410mm420x310x1060mmNet weight 2.6kg/pcs 5.3kg/pcs17.8kg/pcsGross weight 6.5kg/ctn12.6kg/ctn21.2kg/ctnFinish Rosewood /Walnut Pearl/Whitesandex/Blackwood Vinyl Rosewood /Walnut Pearl/Whitesandex/Blackwood VinylRosewood /Walnut Pearl/Whitesandex/Blackwood VinylStandard accessories spike/spike seat Optional accessories3-way floorstanding speaker3-way floorstanding speaker2-way centre speakerbass reflex bass reflex bass reflex3-way3-way2-way165mm Woven Kevlar Cone x 2200mm Woven Kevlar Cone x 2130mm Woven Kevlar Cone x 2 130mm Woven Kevlar Cone130mm Woven Kevlar Cone25mm Soft Dome25mm Soft Dome25mm Soft DomeNo No Yes89dB89dB89dB25-150W25-200W25-150W102dB110dB95dB4Ω6Ω 8Ω Compatible3.0Ω 3.1Ω4Ω40Hz - 20kHz35Hz - 20kHz60Hz - 20kHz35Hz32Hz65Hz470Hz & 2.7kHz350Hz & 2.5kHz 2.3kHzMid internal 10.6L Mid internal 8L11.8LBass internal 37.2L Bass internal 66.3L(998+25)mm(1103+25)mm(174+16)mm204mm250mm470mm(366+28)mm(396+28)mm(236+28)mm480x320x1120mm510x365x1225mm560x3320x280mm21.6kg/pcs29.4kg/pcs8.5kg/pcs25.2kg/ctn34.5kg/ctn10kg/ctnRosewood /Walnut Pearl/White sandex/ Blackwood Vinyl Rosewood /Walnut Pearl/White sandex/Blackwood VinylRosewood /Walnut Pearl/White sandex/Blackwood Vinylspike/spike seat spike/spike seat rubber feetcentre base。
