Power LED (red)
This LED indicates that the AC power line cord is plugged into
a live AC outlet. If the main AC line fuse ever opens, this LED
will go out. To use the Auto-On feature, this LED must remain
on at all times (i.e., with an unswitched outlet). The power
switch has no effect on this LED.
Active LED (green)
The primary function of the LED is to show amplifier
operational activity. In the Auto-On mode, this LED turns on at
the presence of an audio signal to the input jacks. The first time
AC power is applied to the Sonamp
®
, the Active LED will light
for about 3 minutes and then extinguish. This is a normal
reaction of the Auto-On circuitry the very first time it receives
power. Thereafter, the Sonamp is ready for automatic
operation. In normal Auto-On operation the amplifier will
respond “on” within 1.5 seconds it will turn “off ” about 3
minutes after the signal ceases.
Whenever AC power to the Sonamp 2120T has been
interrupted, the Active LED will light up for about 3 minutes
when power is first restored. The active LED functions as a nor-
mal on/off power indicator when the Auto-On feature is defeated.
Protection Circuits
The Sonamp has numerous protection circuits. If any are
triggered, the green Active LED will flash and you may hear the
sound of the protection relay clicking to protect the amplifier.
After the fault has been corrected, the unit will automatically
reset itself for normal operation. But it is advised that you turn
off the power switch while you are trouble-shooting for
shorted connections of faults with source components.
MAINTAINING YOUR SONAMP 2120T
The Sonamp 2120T requires no periodic maintenance and has
no user serviceable parts inside. Do not remove the top cover.
Doing so will increase your risk of electric shock. To keep clean
use only a soft cloth and never use any solvents or abrasives.
Fingerprints may be removed with a soft cloth moistened only
with a few drops of water.
