Page 3: Important Ac Power Information
Please read this manual thoroughly from front to back and keep it close at hand during operation. The Studiomaster POWERHOUSE consoles have, in one compact box, a comprehensive mixing console, built- in 127 program Stereo Digital Reverb, dual graphic equalisers, and a 2x300W power amplifier. -
Page 4: Important Cooling Information
Powerhouse 300 The voltage selector (the square shaped part which can be levered out) contains the AC fuse. This is the voltage selection procedure. Check that the pointer (see diagram above) is pointing at the local AC supply voltage (100, 120, 220 and 240V are stamped on the voltage selector). If it is, then go ahead and connect AC power to the console. - Page 5 Powerhouse 300 2:1 INPUT CHANNEL NOTE: Use either the MIC or LINE input and NOT both together as this could damage the MIC input circuitry or the equipment connected to it. 1 MIC INPUT Female XLR wired Pin 1 = Ground, Pin 2 = +ve phase. Pin 3 = -ve phase. The channel may be driven with a low impedance balanced microphone.
- Page 6 Powerhouse 300 2:2 OUTPUT SECTION DIGITAL REVERB The POWERHOUSE consoles have a built in reverb with a total of 127 programs. The various programs are clearly labelled, on the front panel, for rapid accessing of the desired effect. The reverb is stereo, and its outputs are connected to the left and right busses. The ON/OFF button switches the DIGITAL REVERB on or off.
- Page 7 Powerhouse 300 determined by the REVERB FADER. This fader controls the level INTO the reverb, and when adjusting it, the O/LOAD LED should be checked to make sure that the too high a signal level is not being fed to the reverb.

Their main purpose is for the patching in the pre-amp/crossovers which are supplied with some compact speaker systems. -

Powerhouse 300 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. -
Page 11: The Equalisation Section On The Input Channels
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. - Page 12 Powerhouse 300 with "dry" input signals using the channel faders. Turning REV on each of the inputs 1 to 5 by the same amount means that the same mix levels that were sent to the left and right busses by the channel faders are now at the REVERB FADER.

Powerhouse 300 MORE ABOUT THE MON SYSTEM The MON system on POWERHOUSE consoles has a number of useful additional features. The REVERB can be routed directly to MON by depressing the REV TO MON button. If the built-in stereo 2x300W amplifier is not being used for the main mix, then it can be used to power the foldback system if the L- R/MON button below the TO AMP control is depressed. - Page 14 Powerhouse 300 3:9 THE OUTPUTS There is a choice of two outputs for the main stereo mix on POWERHOUSE consoles; the LINE OUTS, and the amplifier OUTPUTS. The amplifier OUTPUTS in most cases would be used to drive the main P.A. loudspeakers (the L-R/MON button below the TO AMP level control must be released).
