Preamp Out
The Preamp Out jack is a line level output from the preamplifier section
of the TCA-500C 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 mono plugs on both ends,
this jack can be used to treat this TCA-500C as a “Master” unit, which
can control a second TCA-500C 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.)
Power Amp Input
The Power Amplifier Input accepts line level signals from another source
to the power amplifier and local speaker in the TCA-500C Combo
Amplifier. When used, this jack will disconnect the internal preamplifier
signal from going to the Power Amp. Only the external signal coming in
on the TS mono plug will be amplified through the speaker.
PRE OUT / PA IN (jacks, rear) –
Theses jacks allow two
TCA-500C combo’s to be slaved together. Connect a lead from the
Pre Out of the Master combo (
The combo that the guitar is plugged
into
) to the PA In of the Slave combo. The output from the speaker
of the master and slave combo’s will now be the same. When
adjustments are made to the master combo controls both combos’
outputs will be affected.
(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.)
