24VDC Output
This socket provides an isolated 24 volts DC to power up the FP-100 foot pedal.
It accepts a special twist lock plug for a secure connection of power to the pedal.
A power lead with locking connectors is supplied with the TCA-500 Amplifier.
Input
High impedance (1Meg Ohm) instrument input - will not load down your guitar
pickup or adversely affect your tone. It accepts a standard 1/4 inch type TS plug
for guitar level signals.
Input Gain
and
Red Overload
LED
This control sets the gain for the first amplification stage. And is used in
conjunction with the MASTER LEVEL control, it also affects the level for the
Pre EQ
Pedal insert “To/Send”
jack and the maximum level to the
EFX Send
jack (both of which are on the rear panel). Start at 3 or 4 and adjust as needed.
It’s important to understand the function of this control as its setting
impacts other controls and the overall sound. When a guitar signal is fed
into the amplifier, it is necessary to increase the signal level to minimise
noise that might be added in the following stages. Typically, guitar pickups
with a high output require a lower gain setting and pickups with a low
output required a higher gain setting.
In the lower right-hand corner of the Input Gain box is a red (Input/EQ
Overload) LED that indicates an overload is occurring in the pre-
amplifier stage. If this LED flashes on frequently, or stays on while the
guitar is played, the Input Gain is setting is too high and should be
reduced in order to avoid distortion of your sound.
