Green LED
The green LED will blink; On for a short time then Off, once a second while the
temperature is below the Low setting. This “wink” (short blink, once per second)
lets you know that the Thermal Management System is working. As the
temperature increases the green LED will come On solid while the temperature is
at or above the low setting.
Yellow LED
The yellow LED will come On solid if the temperature is at or above the medium
set point.
Red LED
The red LED will come On solid if the temperature is at or above the high set
point.
When the Power Amplifier switch on the rear panel is switched to
OFF
these LED’s will alternate,
blinking in groups of three (3) blinks, first showing the appropriate LED(s) to indicate temperature, then
all three LEDs will blink 3 times, then the LED(s) showing temperature will blink 3 times , then all
three, and so on.
Note: If the temperature is High, then all three (3) LEDs will blink each time.
MAINS Switch /
Blue AC On LED
Mains Power ON / OFF switch / AC ON LED (blue) –
The AC power
switch is located on the front panel. The
blue AC On LED
on the front
panel indicates AC mains power is applied and the AC Mains Power
switch is
On
. After the switch is turned on, there will be a delay of about
five seconds before the blue LED lights, indicating the amplifier is ready
for use. This delay is intentionally provided to mute boot-up noise from
external effects units.
Mute
MUTE ON switch / LED (yellow) –
The Mute ON switch mutes the
output to the Power Amplifier, to the XLR Direct Out and to the PRE
OUT; it does not affect the Headphone output, Effects Send and Pedal
TO outputs.
The Mute circuitry is designed to be super quiet when switched On and
Off.
When the Mute is On the Yellow Mute LED is lit
.
The Mute system in the TCA-500C is very handy for string replacement, practice
licks, tuning, and effects adjustment during live venue situations.
