MASTER
57. 7-BAND EQUALIZER
The EQ ON switches activate the 7-band graphic EQs within
the PowerMate's master channels. The EQ's insert point is post
master fader and pre power amplifi er. The EQ is bypassed when
the EQ ON switch is not locked in its "ON" position. The two gra-
phic EQs provide seven frequency bands, each. Through these
faders you are able to match the overall sound optimally to the
acoustic conditions of different locations or shape it according to
your personal taste. Each frequency band allows ±10dB increase/
attenuation in the corresponding range with a quality of Q=1.4.

The frequency ranges as well as the characteristics of the faders
are very praxis-oriented. In case you want to have a clear and high-
ly intelligible sound, which, as a side effect, provides the cymbals
with more crisp, you should raise the levels of the 8kHz or 16kHz
band a bit. If the MIDs are nasaling you should attenuate the mid
range by some decibels. To provide the kick drum with more punch
you have to boost the low frequency range, using the 80Hz or the
250Hz controls. In case the overall sound is undefi ned with too
much bass, lowering the levels of these two frequency bands will
solve the problem.
Especially when using the equalizer, you should be aware of the
fact that in most cases less adjustments provide better results.
Thus, your fi rst choice should be to establish the mix using only
the input channel EQs and see if you get a satisfactory result. If so,
you can use the graphic EQ for the AUX3 (monitor), where in most
cases it is more needed. You will fi nd the description of how to inclu-
de the graphic EQ in the monitor bus later in this owner's manual.
58. MASTER LED-DISPLAY
The PowerMate offers two 10-segment LED-chains to monitor
the output levels of the L/R master signals. The indication range
of the LED-meter is 33dB, displaying the levels in dBu which are
present at the EQ OUTPUT respectively at the POWER AMP IN-
PUT. The meter's 0dB mark is referenced to a 0dBu output signal
at the POWER AMP INPUT. Further increasing this level leads
to the power amplifi er's maximum input level of +6dB – equaling
an output power of 500 watts at 4 ohms per channel. Higher le-
vels are not displayed, since the amplifi er's processor limits the
signal at this point. The LIMIT LED of the status indicator sec-
tion will light, showing that the internal limiter is now activated.
