ENTURY ERIES
LM-12 Output Module
The LM-Mono Group output module is the primary output
module on the LM-12 and the secondary output module on the
LM-8+4 and the LM-20
Output Meter
Monitors the post-fader output signal via a ten-segment LED
array.
Output EQ
Controls the the equalization of the output mix signal through
three bands, via six controls. The upper knob of each band
determines the center frequency (high-1kHz-20kHz, mid-
300Hz-8kHz, low-40Hz, 1kHz), while the lower knob adjusts
the amount of boost or cut.
EQ IN Switch
Inserts the EQ section into the output channel signal. An asso-
ciated LED illuminates when the switch is down.
High Pass Filter Switch
Inserts the High Pass Filter into the output signal.
HPF Frequency Control
This knob adjusts the high pass filter frequency from 20Hz to
400Hz. The filter operates at a -12 dB per octave rate.
Return Level Controls
Adjusts the level of return signals 1 and 2 in the output. These
signals come from the Master Section. See Returns 1 & 2 on
the Master Section description for more information.
Sub Input Controls
Adjusts the level of cross-mix in the output from mono outputs
11 and 12.
Polarity Reverse Switch
Inverts the polarity of the output.
Insert On Switch
Turns on the insert loop for the output signal. If a complete
insert loop is not present depressing this switch will mute the
output.
TB Enable Switch
Injects the talkback signal from the master section into the
group output.
DIM Switch
Introduces a -6dB drop to the output signal. This is a push
on/push off switch, not momentary.
MUTE Switch with LED
Mutes the output. This switch does not affect the PFL switch
or the Peak and Signal Present LED indicators.
Output PFL
Enables Pre Fader Listening of the output signal. (this signal
can be internally selected post fader)
Output PEAK & Signal LEDs
The red LED indicates that the output is within 3dB of the clip-
ping point.
The green LED constantly displays the level of signal activity
by varying in intensity.

Output Fader

Controls the final output signal level.
Rear Panel Connections
Balanced Out
This XLR connector carries the post-fader output signal from
the associated output module.
Output Insert Send
This 1/4-inch TRS balanced jack carries the send signal of the
output insert loop to the external effect or signal processor.
Output Insert Return
This 1/4-inch TRS balanced jack accepts the return signal of
the output insert loop from the external effect or signal proces-
sor.
