is connected to the OmniStudio USB's MIDI output.

Using the Mic/Inst and Line Inputs

Connect your microphones or instruments to the OmniStudio USB's front panel Mic/Inst inputs 1 and 2. These inputs accept standard three
pin XLR or standard 1/4" TRS (stereo) or TS (mono) connectors carrying mic or instrument level signals, respectively. Regulate the input level
of the incoming signal with the channel's Input Gain knob. If the signal is too hot – indicated by the Clip LED – even with the gain set to
minimum, attempt to reduce the level at the source (by moving away from the mic, or lowering the instrument level). If this is not possible,
you can insert a 20dB pad to reduce the input level, by pressing and engaging the channel's Pad switch in the IN position.
If you have connected a condenser microphone to the Mic/Inst inputs, press the phantom power switch to activate +48V phantom power
to the mic inputs.
You can connect instruments or line level sources to the OmniStudio USB's rear panel Line inputs 3 and 4. These inputs accept standard 1/4"
TRS (stereo) or TS (mono) connectors. The input levels to inputs 3 and 4 are controlled at the audio source.
If you need to record with four preamps, you can connect the line outputs of external preamps to Line Inputs 3 and 4. If you have an external
mixer with preamps, you can take a direct output from the mixer channel to Line Inputs 3 and 4.

Using the Input and Output Level Switches

Using the rear panel Line In 3/4 Input Level switch, and the Direct Out 1/2 and 3/4 Output Level switches, you may change the operating line
level for the OmniStudio USB's Line In 3 and 4 inputs and Direct Outs 1-4. In the OUT position, the level is set to a +4dBu line level. Pressing
the input level switch and locking it to the IN position changes the operating line level to a -10dBV setting.
The Line In 3/4 Level switch affects the input level for both input 3 and 4. The Direct Out 1/2 Level switch affects the output level for Direct Out
1 and 2; the Direct Out 3/4 Level switch affects the output level for Direct Out 3 and 4.
It is possible to have +4dB settings for some of the stereo pairs, and -10dB settings for others. This will depend on the operating line level of
