3. Input Section:
The Input channel of the AiR Pro series mixer has two connectors: MIC Input & Line Input.
Please do not use both the Inputs at the same time. Doing so may permanently damage the equipment.
Please ensure that the Gain levels, the Fader Levels & the Aux Controls are set to minimum while connecting or disconnecting inputs.
1. MIC Input:
This electronically balanced XLR input is designed to accept low impedance balanced signals from microphones.

2. Line Input:
The Line input will accept line level balanced or unbalanced signals using 1/4 inch stereo (TRS) Jack. T
he Line
input is designed for instruments like Keyboards, Guitars, Drum Machines and other electronic instruments.
4. Gain Control:
Turn this knob to control gain of both MIC and Line Input signal. Please do not operate at high gain levels
as this may lead to audio clipping causing signal distortion.
5. Low Cut / High Pass Filter (HPF):
This switch activates the high pass filter and allows you to cut down unwanted low
frequencies. With the Low Cut function, you can attenuate all signals below 100Hz. Please keep this button pressed if you do not
need these extremely low frequencies. It can be used to reduce hum noise infected by the mains power supply, stage rumble,
microphone ‘popping’ and cleaning up a muddy mix.
.
6. EQ Section:
The AiR series mixer has 3 Band Equalizer with frequency sweep on Mono channels and 2 Band Equalizer on
Stereo channels (3 Band Equalizer in AiR Pro 28 & AiR Pro 36). The EQ is designed to be easy yet effective to use. It can be
used to cut or boost certain frequencies to achieve a particular tone, or to eliminate any unpleasant characteristics.
HF Control:
The HF control can be used to cut or boost up to +/- 15dB at 12 kHz.
MF Control:
The MF control can be used to cut or boost up to +/- 15dB at 2.5 kHz. Mid frequency variation is from 100Hz
to 3Khz. (Only for Mono Channel)
LF Control:
The LF control can be used to cut or boost up to +/- 15dB at 80Hz.
7. AUX:
This knob is used to adjust the level of the channel signal Pre/Post being fed to the Aux bus. Please refer to the following
table for Aux configuration.
Tip: The Aux send is used to provide a monitor mix to artists and also as an input to a multi-track recorder.
8. Pan Control:
This knob is used to pan the incoming signal between the Left and Right output channel. This knob can also be
used to route (send) the signal to particular Group outputs as selected by the routing switches.
9. Peak LED:
This LED glows when the incoming audio signal is clipping.
10. Mute LED:
This LED is indicates that channel is muted.
