Operates on one 9 volt battery (not included).

You could use an alkaline or lithium type battery for the longest operating type.

The adapter can also operate without a battery for limited functions

4.     Level Meter

Indicates the sound level in dB for each channel

5.     Gain Switches

Selects LOW for unity gain or HIGH for +20dB boost

6.     Peak Switches

The mono mode is for one mono microphone recording. It can send the mono audio signal

to each channel and output stereo audio signal.

The stereo mode is for two channels recording. It provides two separate channels of audio.

9.     GND1/GND2 Ground Switch

Eliminate ground hum and noise for getting the best sound

GND1: Separate the output signal ground from the input signal ground. To avoid the noise

of the input signal passing to the output signal. This noise is usually caused by AC power,

for instance, mixer with AC power adapter

GND2: Connect the output signal ground to the input signal ground

10.  POWER Switch

Main power switch for adapter

11.  PH 12V/OFF/48V

Optional 12 or 48 volt phantom power for condenser microphones that require phantom

power to operate.

Many microphones will operate on 12V to save battery power.

12.  LINE/MIC/PH Switches

Select LINE or MIC or Phantom levels

The MIC level is for self powered microphones or wireless system.

The LINE level is for mixers and other audio devices with a line level output, set the switch to

LINE to attenuates the signal to about 40dB.

The PH level is for microphones that require phantom power.

13.  XLR/RCA Switch

Select XLR for headphone monitoring audio from the microphones during

Recording.

Select RCA for headphone monitoring playback audio from the camera.
