3. If the transformer thermal protection circuit is activated.
4. If amplifier output wires develop a short-circuit.
5. Should the amplifier output stage become non-operational.
The fault status of the amplifier can also be monitored remotely
by attaching a signalling device to the Fault jack located on
the amplifier back-panel. See the Advanced Features and
Options section of this manual for more information on fault
monitoring and suggestions for signalling device circuity.
Some fault conditions may cause the output of the amplifier to
be muted.
Clip Indicator: Two red LEDs (one for each channel) are lo-
cated on the front panel. The Clip indicators turn on when dis-
tortion is audible in the amplifier output.
Signal Indicator: Two green LEDs (one for each channel) are
located on the front panel. Unlike some of our other amplifiers,
the Signal indicators on the CE-Series amplifier lluminate when
a signal (> –40 dBm) is present at the
INPUT of the amplifier
for that channel. Because these indicators receive the signal
before the level controls, they can be used to troubleshoot wir-
ing problems within a system. If the Signal indicator for a chan-
nel is not lit, no signal is reaching the amplifier on that channel.
Power Indicator: A green LED is located on the front panel.
The Power indicator lights when your CE-Series amp has been
turned on and has power.
Level Controls: Two rotary level controls (one for each chan-
nel) are located on the front panel. Use these controls to adjust
each channel’s output. To decrease the level, rotate the control
counter-clockwise (to “
∞”). To increase the level, rotate it clock-
wise (to “0”).
If you wish, the level control knobs may be pulled from the front
panel and the holes plugged with the supplied caps to mini-
mize tampering of control settings.
Input Sensitivity Switch: A two-position Input Sensitivity
switch is located on the back panel near the input connectors.
Your amplifier is shipped from the factory with this switch set to
the 1.4-V position. At this setting , a 1.4-V input signal will drive
the amplifier to full power into an 8-ohm load when the level
controls are turned to maximum. This setting works best when
the amplifier is being driven by equipment with a +4 dBu out-
put—an output level at which most professional equipment op-
erates.
If required, the Input Sensitivity switch can be moved to the
26-dB position, so that the amplifier provides a fixed voltage
gain of 20 (or 26 dB: 1 volt in, 20 volts out). This setting works
best with output levels of +10 dBu (2.5 volts RMS) or more.
Some brands of DJ mixers, in particular, have output levels in
this range.
Selecting the correct sensitivity will allow your equipment to
operate at its optimum level and improve the signal-to-noise of
the system.
Mode Switch: This two-position switch, located on the back
panel, allows the selection of either Stereo or Bridge-Mono
mode of operation.
