Channel Control Section
1. MIC Input Jack.
These are balanced XLR-type microphone input jacks (1:Ground; 2:Hot; 3:Cold).
2. LINE Input Jacks.
These are balanced TRS phone-jack line inputs (T:Hot;R:Cold; S:Ground).You can connect either
balanced or unbalanced phone plugs to thesejacks.
3. INSERT Jacks
Each of these jacks provides an insert point between the equalizer and fader of the corresponding input
channel. The INSERT jacks can be used to independently connect devices such as graphic equalizers,
compressors, or noise filters into the corresponding channels.These are TRS(tip, ring, sleeve) phone
jacks that carry both the send and return signal (tip = send/out; ring = return/in; sleeve =ground).
4. LINE Input Jacks.
These are unbalanced phone-jack stereo line inputs.
5. GAIN Control
Adjusts the input signal level.To achieve the best balance between S/N ratio and dynamic range, adjust
the level so that the PEAK indicator 11 lights only occsasionally and briefly on the highest input transients.
6. BAL.
The BAL control determines the stereo positioning of the channel signal on L and R buses.
7. Equalizer (HIGH, MID and LOW)
This three-band equalizer adjusts the channel's high, mid, and low frequency Band. Setting the knob to t
he 0 position produces a flat frequency response.The knob to the right boosts the corresponding
frequency band, and turn to the left weaken the frequency band.The following table shows the EQ type,
frequency,and maximum cut/boost for each of the three bands.
8. Channel Fader
Adjusts the level of the channel signal. Use these faders to adjust the balance between the various
channels.
9. AUX Control
Adjusts the leve of the signal sent from the channel to the AUX bus.
10. EFFECT Controls
Adjusts the level of the signal sent from the channel to the EFFECT bus. Note that the signal level sent
to the bus is also affected by the Channel fader
