4 − Using the mixer
Channels 7-8 and 9-10 have 2-band EQ with HI and LOW shelving frequency boost and cut adjustment ranges of ±15 dB.
Use the EQ HI knob to boost or cut the frequency band above 12 kHz, and use the EQ LOW knob to boost or cut the frequency band below 100 Hz.
AUX sends
The mixer has 2 AUX busses (AUX 1, AUX 2).
AUX 1
Signals from channels 1–6, 7-8 and 9-10 can be sent to the AUX 1 bus by adjusting their AUX 1 knob levels. Use the AUX MASTER 1 knob to set the final level of the AUX 1 bus signal that is output from the AUX SEND 1 jack on the rear panel. You can also monitor the AUX 1 signal using headphones attached to the mixer.

You can set whether the signal sent to the AUX 1 bus is pre-fader or post-fader. When the PRE switch is ON (switch pushed in), the signal is sent to the AUX 1 bus after EQ adjustment but before fader adjustment so the fader position has no effect. When the PRE switch is OFF (switch not pushed in), the signal is sent to the AUX 1 bus after being adjusted by the fader.
Ordinarily, if you want to use AUX 1 for stage or cue monitoring, turn the PRE switch ON to create a mix that is entirely independent from the main mix. To use AUX 1 as an effect send, turn the PRE switch OFF.
In addition, there is a TO AUX 1 switch on channels 13-14 on all M-164 mixers, as well as on channels 15-16 on M-164FX and M-164UF mixers and channels 11-12 on M-164UF. Turn this ON to send the post-fader signal to the AUX 1 bus. For example, input an effect return to a pair of these channels, and use this switch to set whether or not to send this to a monitoring setup on the AUX 1 bus.
AUX 2
Signals from channels 1–6, 7-8 and 9-10 can be sent to the AUX 2 bus by adjusting their AUX 2 knob levels.
The signal sent to the AUX 2 bus is always post-fader, so the AUX 2 bus is usually used for an effect send. Use the AUX MASTER 2 knob to set the final level of the AUX 2 bus signal that is output from the AUX SEND 2 jack on the rear panel.
On M-164FX and M-164UF mixers, the AUX 2 signal is also sent to the internal effects. (See “Using internal effects (M-164FX and M-164UF)” on page 23.)
