The Reverb. FX- and Master Section of the ATS 120

An ACCUTRONICS spring system is used to produce the reverb effect in the ATS 120.
The quality of a reverb unit depends largely on the length and number of springs used;

this genuine Accutronics unit generates a warm, realistic effect for the ATS 120 by
having three particularly long springs.

Increasing the degree of distortion on an overdriven sound will tend to make it more

sensitive to reverb; in other words, too much reverb can easily swamp the sound. For
this reason, the reverb effect is differently tuned for each of the three channels. When

you change channels, you will not need to alter the reverb setting to achieve a

similar-sounding effect.

(11) 

REVERB:

controls the amount of tuned reverb for CLEAN, CRUNCH and LEAD.

(12) 

FX-MIX:

determines the relative volumes of the original sound and the signal from an external
effects unit connected to the effects loop. DRY= only original signal; FX= only
processed signal. Intermediate setting allow the proportions of original and processed

signals to be balanced as desired.

TIP: If no external unit is connected up, the FX-MIX control can be used in conjunction

with the ATS STAGEBOARD (optional) to set up an alternative master volume setting.

This can then be called up using the ATS Stageboard.

PROGRAMMING A SECOND MASTER VOLUME SETTING:

 select the channel or

channels for which you wish to program an alternative volume setting. This is done by

turning the appropriate FX-SELECT switch or switches to the ON position (there are 3
located on the rear panel of the ATS 120). Activate the 

 function on the ATS

Stageboard. Set the desired volume level using the FX-MIX control. By turning the
EXT. FX switch ON/OFF, you can now cycle between the two different master volume

settings.

MASTER: 

controls the overall volume of the ATS 120.

MAINS: 

power on/off switch. When switched on, the red LED arrow will be

illuminated.
