MG16/4 panel.
1 GAIN Control
Adjusts the input signal level.
To get the best balance between the S/N ratio and the dynamic
range, adjust the level so that the peak indicator (
2) comes on
only at about maximum input level.
The –60 to –16 scale indicates the MIC input adjustment level.
The –34 to +10 scale indicates the LINE input adjustment
level.
2 PEAK Indicator
Detects the peak level of the post-EQ signal, and lights up red
when the level reaches 3 dB below the clipping level. For
XLR-equipped stereo input channels (9/10 and 11/12 on the
MG16/4; 5/6 and 7/8 on the MG12/4), detects both post-EQ
and post-mic-amp peak levels, and lights red if either of these
levels reaches 3 dB below the clipping level.
3 Switch (High Pass Filter)
This switch toggles the HPF on or off. To turn the HPF on,
press the switch in ( ). The HPF cuts frequencies below
80 Hz. (But note that regardless of the switch setting, the mixer
does not apply this HPF to the line inputs of stereo input chan-
nels.)
4 Equalizer (HIGH, MID, and LOW)
This three-band equalizer adjusts the channel’s high, mid, and
low frequency bands. Setting the knob to the position pro-
duces a flat frequency response. Turning the knob to the right
boosts the corresponding frequency band, while turning to the
left attenuates the band. The following table shows the EQ
type, base frequency, and maximum cut/boost for each of the
three bands.
5 AUX1 and AUX2 Controls
The AUX1 knob controls the signal level that the channel sends
to the AUX1 bus; the AUX2 knob controls the signal level to
the AUX2 bus. The knob should generally be set close to the
position.
If you are using stereo channels, the signals from the L (odd)
and R (even) channels are mixed and sent to the AUX1 and
AUX2 buses.
Allows you to output the signal to the buses regard-
less of the setting of the ST switch 8.
