REVERB

The Accutronics reverb unit has 16 selectable reverb effects accessed by

the rotary switch at the far right of the front panel these are as follows:

Hall 1 &2 Bright hall reverb or warm hall Room 1 -3 hardwood studio,

general ambience and warn room reverbs Plate 1-3 Classic , sizzling and

short style pate reverbs Chorus, Flanger, Delay 1 and 2 125 mS and 190

mS delays Chorus + Room 1 and 2 Chorus+ Room reverb combined

and Chorus + auto wah effect Chorus + delay Rotary speaker simulation.

The reverb effects are available either or both channels accessed by the

selctor switches on the front panel.

From this point the signal is fed to the equaliser circuit and also to the

PRE EQ DI output on the rear panel.

The Equaliser

The 5 band equaliser has frequencies centred at 100 ,340 ,680 ,1k6 and

7khz respectively with an adjustment range of +/- 12 db . the equaliser

affects both channels equally.

Notch filter

Next in the signal chain is the notch filter, Thsi filter has a Q of 5 and the

frequency is adjustable between 80 and 350 Hz. Use of the filter will

enable you to remove most unwanted resonances and low frequency

body feedback.

Effects loop e.t.c

Next is the effects loop , this is a SERIES loop between the preamplifier

and the Power amplifier, also at this point is the Aux Line in which can be

used to input other signal sources, the level of which is controlled by the

volume control on the rear panel.

Incorporated with the AUX line in is a bluetooth receiver so signals can

be wirelessly connected to the amplifier. The Bluetooth Has a disable

switch on the rear panel to minimise noise when not in use and a front

panel light in blue shows when the unit is connected.

Last in the signal chain is the POST DI and LINE out , these outputs con-

tains all of the sources / effects as heard from the speakers.

An overall level control sets the playing volume.

The power amplifier

The Power amplifier is a pure analogue class A/B design that can provide

a continuous power output of 50 or 100 watts minimum into the fitted

Celestion speakers. A phase reversal switch is fitted on the rear panel to

help minimise feed back effects.
