Reverb Level –
Rev ON button
(continued)
The Rev push button switch will activate the internal reverb circuit. The green
LED will light when the reverb is active. The
Foot Switch
connector on the rear
panel can be used to turn the internal reverb Off and On if the
Rev
pushbutton
switch on the front panel is pushed On (in). If either this switch, or an external
switch, is in the Off position, the reverb will remain Off. When an external
remote switch is not used, the default is On. (See back panel Foot Switch)
The built-in reverb is useful if you don’t have an effect processor installed.
It can be switched On/Off from the front panel using the Rev ON button or
by remote control using the Footswitch jack on the rear panel. The reverb
sound has been preset to a general ambience algorithm; the Reverb Level
control adjusts the amount of reverb introduced.
The built-in reverb signal is added to the signal returning from the
EFX Return jack that feeds the Wet side of the DRY/WET Fader.
This means, the DRY/WET Fader must have a proportion of Wet
signal set or the built-in reverb will not be heard. I.e. if the
DRY/WET Fader is set fully Dry no reverb will be heard.
If the TCA-500C is used with a 19” rack effects processor, (such as a
Lexicon MX-200, a T.C. Electronics G-Major/II, or other 1U space multi-
effects unit), we would recommend the built-in reverb be turned off and
patches set up on the effects processor; the reverb algorithms of a good
quality effects processor should be superior to the built-in reverb.
1U 19” Rack Space – (Note: The 1U Rack Space is not available
on the Mini-Combo units.)
The TCA-500C has a built in rack space
below the main amplifier chassis. If no effects processor is installed
in this space a blanking plate should be installed. On the rear panel a
mains switched outlet is provided to power up the effects processor;
50W max. Although the general thought behind providing this space
is to enhance the reverb and delay effects, almost any 1U unit no
more than 8 inches or 200mm deep could be installed in this space.
