Foot
Switch
The Foot Switch jack on the rear panel may be used to switch the TBro and/or
the internal Reverb effects circuit on and off. A ¼ inch TRS (tip, ring, and
sleeve) plug is needed. The sleeve is common, tip is TBro and ring is reverb.
The switch will enable the effects in the closed position.
Note that the type of switch to be used must ‘not’ be a momentary contact type,
but rather a continuously on or off type, such as a toggle switch.
Tuner
Out
The Tuner Out jack on the rear panel performs the same function as the Tuner
Out jack on front panel. It is designed for internal feed to a rack mounted tuner.
Both Tuner Outs, front and rear, may be used simultaneously. The output
impedance is approximately 500 ohms.
Preamp Out
The Preamp Out jack is a line level output from the preamplifier section
of the TCA-500 that can be used to send the fully processed signal to
another power amplifier, powered speaker, etc.
Using a standard guitar cable with 1/4 inch TS plugs on both ends, this
jack can be used to treat this TCA-500 as a “Master” unit, which can
control a second TCA-500 as a “Slave – thus providing a total of 1000
watts of total amplifier power (500 per unit).
(Note that when this is done, a ground lifting device such as a HUM-X
must be used on the “Slave” unit in order to prevent a loud and
unpleasant ground loop hum.)
