2:2 OUTPUT SECTION
1 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. When it is not required, it
should be switched off. Depress for ON, and the adjacent LED will light.
There are six reverb "types" (each of which can be DARK or BRIGHT and have any of
eight reverb times), three reverb effects (which can also have any of eight preset
reverb times) plus seven SPECIAL EFFECTS.
The reverb types are selected by the TYPE button. Each tiroe this button is
depressed, the lit LED above it "moves" down the row to indicate the type selected.
The bank SELECT button selects whether the reverb type is BRIGHT or DARK. The
DARK/BRIGHT selection is shown by the two LEDs adjacent to the BANK SELECT
button.
The TYPE and BANK SELECT buttons also select the three reverb effects and gain
access to the 7 SPECIAL EFFECTS (GATED, DELAY, REVERSE & SPECIAL) by
moving the LED down with the TYPE button, and using the BVMK SELECT button to
toggle between GATED and DELAY, or REVERSE and SPECIAL.
The eight different times available for each of the reverb types and effects are preset
and vary for each type/effect selected. The time is selected by using the
SPECIAL/TIME button in the same way as the TYPE button.
When SPECIAL has been selected, the SPECIAL/TIME button is used to select any
of the 7 SPECIAL EFFECTS. These have all their parameters pre-programmed to
create the effect.
The O/LOAD LED will light when the level of the mix of signals sent to the reverb
(controlled by the REVERB fader reaches a level 3dB below overload occurs to warn
of clipping distortion.
2 POWER ON
This LED lights when AC power has been switched on at the rear panel of the
console.
3 LED METERS
These display the LEFT & RIGHT OUTPUT levels. The meters are 12-segment, 2-
colour with typical VU meter ballistics.
4 GRAPHIC
EQUALISER
The graphic equalisers are assigned to the left and right busses. They control the
equalisation of the mix of signals routed to them by the L-R/GRAPHIC buttons on
each of the input channels. If, when adjusting the graphic equaliser, the overall mix
level becomes too low or too high, the TRIM fader on each graphic equaliser can be
used to compensate for this. To remove the graphic equalisers from the signal path,
simply release all L-R/GRAPHIC buttons on input channels.
5 REV TO MON
Depress this button to route the REVERB to the MON buss (normally used for
foldback).
6 MON FADER
The MON controls on each of the input channels have their overall, mixed level
determined by the MON FADER. This fader controls the output level of the MON
SEND jack.
7 REVERB FADER The REV controls on each of the input channels have their overall, mixed level
