4. Click on the Phantom Power button with the mouse to toggle it on or off blue means on gray means off Line and Microphone The Line and Microphone buttons select the type of input you are connecting to the DMX 4 The difference is the signal level and the amount of gain required Microphones have a low signal level and require higher gain When Microphone is selected the gain can be adjusted from 10dB to 85dB with the slider control See the section Adjusting the Recording Level The slider control will affect the level of the audio in the recording and in the monitor output if the particular input is routed to that monitor Note however that the monitor output level will stop increasing once the slider is up past 65dB This is because the gain above 65dB 26 DMX 4 USB Mixer User Manual is done digitally in your PC and not in the DMX 4 circuitry When Line is selected the gain is fixed at OdB for inputs 1 and 2 If you attempt to move the slider with the mouse it will snap back Inputs 3 and 4 do have a gain adjustment from 8dB to 31 5dB in Line setting Input and Monitor Labels There are text boxes for each Input channel at the top of the Antex Mixer Program There are also text boxes for the Monitor channels When you click with the mouse inside one of these boxes you can type in a name for that channel This will help you to tell who is talking into that particular microphone Antex cannot claim cred

9. eo Wave Devices Record channels 1 and 2 are left and right of Wave Device 1 respectively and record channels 3 and 4 are left and right of Wave Device 2 Power input to the DMX 4 can be from 5 to 15 VDC Power consumption is about 5 watts The unit is supplied with a 9V international wall adapter but can also be powered by battery packs or from an automobile accessory plug cigarette lighter The power indicator LED changes gradually from green at 12 volts to red at 5 volts so the user can note a color shift on battery power when the battery gets low DMX 4 USB Mixer User Manual What s a dB and why should 1 care Throughout this manual the term dB is used This stands for decibel You may think but I just want to record a legal proceeding don t want to be a recording engineer Why should care about this Although dB s may seem complicated mathematically dB 20 x log signal level reference signal level Using dB s gives you a better feel for how changing the volume will sound to your ears For example if you increase the output of your stereo amplifier from 1 10 of a watt to 1 watt this seems like a small change only 9 10 of a watt If you increase the output from 4 watts to 40 watts this seems like a real big change However in both cases you are increasing the output by 10dB and surprisingly in both cases it will sound to you like the music only got twice as loud Negative dB s means quieter 10dB
10. g circuitry and the additional 20dB is done in the digital domain As you increase the gain on any input the level of this audio will get louder in the monitor output and in the recording level However once you exceed 65dB the recording level will continue to increase but the audio in the monitor output will not increase any further Input channels 1 and 2 have a DMX 4 USB Mixer User Manual fixed gain of OdB in line setting Inputs 3 and 4 have an adjustable gain of 8 to 31 5dB in line setting Although the circuitry is capable of a lower gain setting than 8dB the setting is limited in the Antex Mixer Program to 8dB so that it is not possible for the analog circuitry to go into clipping before the A D The monitor outputs are single ended RCA jacks capable of a 2VRMS signal 6dBV The level adjustment range is from 102dB to 25 5dB The output has a 560 ohm internal series resistance to protect it from short circuits to ground The equipment that the monitor output is connected to should have an input impedance of 2K or greater The A D converter sample rate can be set to 8 11 025 12 16 22 05 24 32 44 1 or 48KHz This allows for optimization between file size and audio fidelity All 4 inputs are digitized separately and 4 tracks may be recorded to hard disk The inputs may be mixed in any combination to the 4 record channels using the Antex Mixer Program On your PC the 4 record channels are accessed as 2 ster
