The Telonics TCA-500 Mini-Combo amplifiers do not offer a 1U rack space in order to conserve
weight and space. They are equipped with minimal internal effects.
It is therefore sometimes desirable to add one or more additional effect(s) using small, special
purpose 9 Volt “Stomp-Box” effects units. A proper series mode insert for connecting such
effects units is provided in the form of the “Pre-EQ” Insert/Pedal Loop on the rear panel.
In addition, a dedicated 9 Volt power supply is included in the TCA-500 Mini-Combo
Amplifiers specifically for this purpose. The EFX power jack is located on the rear panel of the
amplifier. It provides 9 Volts DC, at up to 1amp (1,000 mA). The jack is wired in accordance
with the stomp box de facto standard; CENTER PIN IS NEGATIVE (-), outer barrel positive
(+).
ALWAYS check the polarity required by your external effects unit before plugging it into
power.
By using the stomp boxes in this manner, the user is able to connect his/her guitar’s signal
directly to the input of the TCA-500 Amplifier and enjoy the clarity and string separation
provided by the internal studio grade preamplifier, as well as, to establish the noise figure prior
to introducing the processing propagation time loss and A/D & D/A conversion noise inherent in
such stomp boxes
.
Most “Stomp box” or effects “pedal” units should be connected using the “Pre-EQ Insert”/Pedal
Loop on the rear panel of the TCA-500 series amplifiers. Such effects units are of the type;
BOSS RV3, RV5, Strymon DIG, Digitech Polara, Holy Grail, Holy Grail Nano, Strymon Flint,
TC Electronic Hall of Fame Reverb, Mr. Springy, Z-Cat, etc.
To connect a single 9Volt “stomp box”:
First, connect a short ¼ inch TS cable from the SEND output to the INPUT of the effects unit.
(If you are using a STEREO effects unit, use the MONO jacks.)
Then using a second short ¼ inch TS cable, connect the OUTPUT of the effects unit to the
RETURN jack of the Pre-EQ Insert.
When all signal connections have been made and checked, connect the effects unit to the (-) 9 V
power jack on the rear panel of the TCA-500 Mini-Combo amplifiers.
If you wish
to connect more than one 9 Volt effects unit;
for example, delay, followed by
reverb, you may connect multiple units in series within the Pre-EQ Insert Loop.
To do so, connect a short ¼ inch TS cable from the SEND output of the Pre-EQ Insert to the
INPUT of the first effects unit. (If you are using one or more stereo effects unit, use the MONO
jacks.)
Then using a second very short ¼ inch TS cable, connect the OUTPUT of the first effects unit to
the INPUT of the second effects unit.
Last, using a third short ¼ inch TS cable, connect the OUTPUT of the second effects unit to the
RETURN jack of the Pre-EQ Insert.
