Mono Input Channel Section

The following section details four mono input channels.

1.MIC Inputs - Use these balanced XLR inputs to connect low Impedance microphones and low level signals from direct boxes. The MIC inputs feature +48V phantom power, allowing you to use condenser microphones. XLR Connector pin-out - Pin 1: Ground, Pin 2: Hot (+), Pin 3: Cold (-)

2.Line Level Input - Use these balanced TRS ¼” inputs to connect synthesizers, drum machines, effects processors or any line-level signal. You can connect balanced and unbalanced devices to these inputs. TRS phone jacks Connector pin-out - Sleeve: Ground, Tip: Hot (+), Ring: Cold (-)

3.GAIN Control - Variable GAIN control with a range of +5 to +45dB on the MIC input and -20 to +20dB on the LINE input.

4.HPF Switch - The high pass filter rolls off the low frequencies from the XLR MIC inputs from 80Hz and below at the rate of 12dB per octave. The high pass filter allows you to remove the lower frequencies that you don’t want the microphone to pick up. In live sound applications, the high pass filter is useful for removing stage rumble.

5.COMP Control (CH1 & CH2) - The COMP knob adjusts the level of compression applied to the channel. As the COMP knob is turned clockwise, the compression ratio is raised and the output gain is adjusted accordingly. The dynamic range of the channel is narrowed, where softer signals will be magnified and loud signals will be subdued to sit better in the mix.

Too much compression can create a pumping effect, eliminate all dynamic range, and lead to feedback.

6.Equalizer (HIGH, MID, and LOW) - This three-band equalizer allows you to contour a channel’s high, mid, and low frequency bands. When the control is set to the 12 o’clock (detent) position, there is no effect on the signal. Turning the controls fully clockwise will raise the level of the frequency band +15 dB, while turning the controls fully counterclockwise will lower the level of the frequency band -15 dB.
