Input Channels 1-8
1. Bal Line Input
The Bal Line input ¼-inch TRS (stereo)
jack for connecting line-level sources, e.g.
instrument amp line outputs. Balanced or
unbalanced sources may be connected us-
ing balanced or unbalanced shielded cable.
Note: Channels 7 and 8 have
unbalanced instrument-level
¼-inch inputs rather than line-
level so that guitars and bass-
es can be connected directly
to the board.
2. Mic Input
The Mic input is a standard low-impedance
XLR mic-level input.
3. Insert Jack
Use a Y-insert cable (e.g. the Apex A203SPY
or A210SXY) to connect sound processing
– EQ, compressor, etc - directly to an input
channel. Tip=Send, Ring=Return.
4. Gain Control
To aid in matching input signal levels, adjust
the Gain level while using a signal that rep-
resents the loudest signal that will be used; set the Gain just
before the Limit LED begins to illuminate. This will optimize the channel’s gain for a given
source’s output voltage. During a sound check, depress the channel Solo Switch and using
the Gain control, set the PFL level to O (zero dB) on the VU Meter display. The channel’s
Limit LED can also be useful as a Gain indicator.
5. HPF Button
High-pass filter, press to roll off the bass under 80Hz on vocal, guitar, etc. channels in
order to minimize microphone handling noise and unwanted low-frequency sound spillover.
6. Equalization
The Low and High EQ controls are +/-15dB shelving at 80 & 12 kHz respectively. Mid =
–25 dB to +12 dB with Sweep from 80 Hz to 8 kHz.
7. Mon 1 and Mon 2 Controls
The monitor signals are post-EQ, pre-fade and send signal to their respective Mon Send
masters and Monitor Out jacks.
8. EFX Control
The EFX Sends are post-EQ and post-fader. The channel's signal is routed through the EFX
Send control to the Internal Effects unit and the External Effects Send jack.
9. Aux Control
The Aux path sends post-EQ, post-fader signal to the Aux Send master and Aux Send jack.
