38 - MASTER LED-DISPLAY
The PowerMate offers two 10-segment LED-chains for optical monitoring the output levels of the L/R master signals.
The indication range of the LED-meter is 40 dB, indicating the levels that are present at the master outputs in dBu. The
meter's 0 dB mark is referenced to a 0 dBu output signal at the mixer output. Further increasing the level leads to the
power amplifier's maximum input level of +8 dBu – equaling an output power of 1000 watts into 4 ohms per channel.
Although higher levels are being displayed, the power amp's clip limiter already limits the signal, which is indicated by
the lit LIMIT LED in the status display. As soon as a PFL button is engaged, the PFL LED lights. The meter instrument in
the master section is simultaneously switched, so that the left LED-chain indicates the level of the actually chosen chan-
nel (in dBu). The right LED-chain indicates the level of the summed post-fader master output.
39 - STANDBY
Pressing the STANDBY switch mutes the output signals at the MASTER A OUT L/R, MASTER B OUTPUTS L/R, AUX SEND
and MONITOR outputs. The outputs REC SEND L/R and record channels of the DIGITAL AUDIO INTERFACE are still op-
erational. The STANDBY LED lights indicating that stand-by mode is engaged and that input channel signals are not out-
put via the speaker systems.
HINT: It is possible to playback the signal of stereo input 11-12 in standby mode. Therefore the entry Play 11-12 at
STDBY in the Device Setup menu must be enabled, see page 27 for details.
CAUTION: The signal feed to the internal power amplifier is also interrupted.
40 - MASTER L/R
FADER
Level controls to adjust the output signals of the left and right master outputs (MASTER A OUT L/R).
CAUTION: Please, make sure to set the input channel faders or at least the master faders to their minimum posi-
tion, or to engage the STANDBY switch, before connecting an external sound source to an input of the
PowerMate. This will save you, your audience, and the equipment from unnecessary stress.
41 - MASTER A OUT L/R
The signals at the MASTER A OUT L/R outputs are post master fader and mainly meant to feed additional, external power
amplifiers. Through these outputs it is also possible to establish two-way active system set-ups. In this case the active
crossovers – respectively the active subwoofers – have to be connected to the MASTER A OUT L/R outputs. If you want
to use the internal power amplifier to drive the high frequency cabinets, the treble signal coming from the crossover has
to be fed back into the PowerMate via the POWER AMP INPUTS L/R connectors.
42 - POWER AMP INPUTS L/R
The POWER AMP INPUTS L/R are also provided via electronically balanced phone jacks with breaker function. When
inserting a phone plug, the signal path gets split up between the master and the internal power amplifier, which allows
operating the internal power amps via POWER INPUTS AMP L/R inputs.
43 - MASTER B OUTPUTS L/R
At the MASTER B OUTPUTS the L/R master audio signal is present that can be used for additional monitoring, side fill
and "next door" applications, or for the connection of a delay-line or subwoofer. The output is pre/post- and also stereo/
mono-switchable.
44 - MASTER B
This control allows adjusting the level of the MASTER B output. The signal levels at MASTER A OUT L/R and MASTER B
OUTPUTS L/R are identical if the MASTER B control is set to the position „5" and the PRE/POST switch is set to POST.
45 - PRE/POST MASTER B
OF
When PRE is selected the MASTER B is outputted pre master faders and pre GEQ, i.e. the level at the MASTER B OUT-
PUTS is independent from the master faders settings. When POST is selected the MASTER B is outputted post master
faders, i.e. the level at the MASTER B OUTPUTS depends on the setting of the master faders. Controlling a connected
Sub's level via master fader makes sense when using an active subwoofer, so in this case select POST. For monitoring
applications, e.g. side fill on the stage, using the pre-fader setting seems more reasonable.
46 - STEREO/MONO MASTER B
OF
When STEREO is selected the MASTER L/R signal is not changed and outputted in stereo. When MONO is selected the
MASTER L/R signal is summed and outputted in mono at MASTER B L and also MASTER B R. Using MONO is recom-
mended when mono subwoofers are connected to MASTER B outputs.
