CE-Series
Amps with an Attitude!
3 Operation
Operating a
CE-Series
amp is very straight-forward.
Indicators
See Figure 3.1 for positions of front-panel controls and indica-
tors.
Fault: OFF is good. This red indicator will blink under five dif-
ferent conditions:
1. When the amplifier is first powered up, until the unit is
ready for operation.
2. If the heatsinks reach a temperature above normal work-
ing limits.
3. If the transformer thermal protection circuit is activated.
4. If amplifier output wires develope a short-circuit.
5. Should the amplifier output stage become non-opera-
tional.
This circuit may be monitored remotely by plugging into the
back-panel RJ11 jack (Fault), and using a circuit like the one
described in Figure 5.2. Under some conditions, the output of
the amplifier will be muted.
Clip: The red Clip indicators turn on when distortion is audible
in the amplifier output.
Signal: Unlike some of our other amplifiers, on the
CE-Series
amplifiers, the green signal indicator illuminates when a signal
(> –40 dBm) is present at the
INPUT
of the amplifier. This indi-
cator is before the level control, so it can be used to trouble-
shoot wiring problems within a system. No green glow, no
signal is reaching the amplifier!
Power: The green Power indicator turns on when your
CE-
Series
amp has been turned on and has power.
