Raising these faders will show the signal level on the LEFT/RIGHT bargraphs and it can be heard in
the headphones (the headphones also have their own level control).
If loudspeakers are connected, then the TO AMP control should be turned clockwise, then the sound
will also go to the loudspeakers. DO NOT allow the signal to go beyond the first red LED on the
bargraph.
3:4 THE EQUALISATION SECTION ON THE INPUT CHANNELS
The function of equalisation is to increase or decrease selected frequencies to either achieve a particular
sound, or eliminate an unpleasant characteristic.
To set the EQ flat (no frequencies cut or boosted), set to zero (centre) the three knobs calibrated in dB. Turn
clockwise the HF (treble) control, then turn it back to zero and compare the sounds. Notice the difference?
What you have done is BOOST high, or treble, frequencies. The EQ network covers the whole range of
audible frequencies from treble to bass.
The electronic characteristics and frequencies of STUDIOMASTER EQ are unique and are developed to
SOUND good. The main purpose of EQ is to correct deficiencies in a sound source's frequency response,
but used creatively it can also enhance sounds. POWERHOUSE has an EQ network that when mastered
can make mediocre sounds good, and good sounds excellent. Practise is recommended.
3:5 REV, AUX & MON
The POWERHOUSE consoles have three controls on each input channel which can be used to send the
input channel signal to be processed, or used elsewhere; the REV, AUX and MON controls.
THE REV CONTROL
Turning this control clockwise sends the input channel signal to the built-in DIGITAL REVERB. By using
several REV controls on the input channels a mix is created at the REVERB FADER. The setting of this
fader controls the level of signal fed to the REVERB. When adjusting it, check that the REVERB O/LOAD
LED does not light.
THE AUX CONTROL
The AUX control is just like the REV control, but allows an external effect processor to be used. Adjusting
several AUX controls creates a signal mix at the AUX SEND control which sets the level of the output from
the AUX SEND jack. This would be connected to the input of an effect processor such as delay, enhancer,
compressor etc.
Like the REVERB FADER, the AUX SEND control alters the signal level fed IN to the effect, so check the
overload indicator of the external effect to avoid clipping or distortion.
REV & AUX, POST-FADE
The REV and AUX controls are "post-fade". Post-fade means that their level is affected by the position of
the channel fader. They are effects sends. The reason for this is that a mix is set, say from inputs 1 to 5,
