57. 7-BAND EQUALIZER
The EQ ON switches activate the 7-band graphic EQs within the Power-
Mate’s master channels. The EQ’s insert point is post master fader and pre
power amplifier. The EQ is bypassed when the EQ ON switch is not locked
in its “ON” position. The two graphic 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 highly 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 undefined
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 first 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 find the
description of how to include 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 INPUT. The meter’s 0dB mark is refer-
enced to a 0dBu output signal at the POWER AMP INPUT. Further
increasing this level leads to the power amplifier’s maximum input level of
+6dB – equaling an output power of 500 watts at 4 ohms per channel. Higher
levels are not displayed, since the amplifier’s processor limits the signal at
this point. The LIMIT LED of the status indicator section will light, showing
that the internal limiter is now activated.
