USING THE POWERHOUSE
3:1 FIRST THINGS FIRST
Set all console controls to their minimum, or zero position: all levels fully anticlockwise, pans to centre,
faders to oo. Make sure all switches are set OUT. Switch OFF +48V Phantom Power. Connect either
loudspeakers (min. impedance 4ohms) to the OUTPUTS, or stereo headphones (min. impedance 400ohms)
to the PHONES jack.
Switch on the console.
3:2 THE INPUT CHANNEL CONNECTORS
For each input channel there are two connectors: a female XLR labelled MIC and a standard 0.25" stereo
jack labelled LINE. The MIC socket is designed for low level signals, typically generated by microphones.
The LINE socket is for higher level (or "line level") signals produced by drum machines, keyboards, some
electric guitars, tape machines etc.
NOTE: Use only the MIC or LINE socket on an input channel, NEVER both together.
For the purpose of setting up the console, connect a keyboard or tape machine to the LINE input of a
channel so that a continuous signal is fed to the channel).
At this stage, a signal has entered the console but nothing can be heard.
3:3 HOW TO GET THE INPUT SOUND THROUGH TO THE HEADPHONES
1 The GAIN control. Adjust this control until it reads about 20 on its scale. The signal within the input
channel has its level determined by this control.
2 The CLIP indicator. Check that this LED is not lit. This LED will only light when the signal level within
the channel (pre- or post-fader) is too high. It illuminates just before "clipping" occurs, to warn that
the channel is near its limit. If a signal clips, then it will be distorting. If it does light, then take one of
the following steps:
a
Reduce the GAIN control level until the light goes off.
B Reduce the output level of the input source (keyboard etc.).
3 The PAN control. All inputs are routed to the left and right busses (see L-R/GRAPHIC button below).
The PAN control determines how much of the signal goes to left or right. In the centre position, the
input signal level is equal on both left and right busses.
4 The L-R/GRAPHIC button. Depressing this button will send the input channel signal to the left and
right busses via the graphic equalisers. To bypass the graphic equalisers, leave the button released.
5 The input channel FADER. The output level of the channel is set by this control, and for the time
being, it is best set at 0dB on its scale. At this point, raising the channel fader presents the incoming
signal to the left and right busses and the level of this signal is now passed directly to the
LEFT/RIGHT faders.
