1. POWER INDICATOR:
The green LED indicates that AC power is supplied to the unit‚ the power switch is ON and the unit is
functional with no faults. If the amplifier has a thermal fault condition‚ this LED will not illuminate.
2. SIGNAL INDICATORS:
Yellow LEDs indicate signal presence at that specific channel output (identical on each channel).
3. CLIP (DDT™) INDICATORS:
Any time a channel is driven into hard, continuous clipping, the DDT circuit will automatically reduce the
channel gain to a level just slightly into clipping, guarding the loudspeakers against the damaging high power
continuous square waves that may be produced. Situations that may activate the DDT circuit include
uncontrolled feedback, oscillations or an improper equipment setting or malfunction upstream from
the amplifier. On the SA-4200™, normal program transients will not trigger DDT; only steady, excessive
clipping will. The LEDs will illuminate red when the DDT circuitry is active (identical on each channel).
4. INPUT LEVEL CONTROLS:
These controls adjust the signal level to the power amplifier inputs. Maximum input sensitivity is achieved
at the fully clockwise setting. These controls are detented to allow the input sensitivity of the channels to
be closely matched. This is essential in the bridged-output mode. See MODE CONFIGURATION on pages
18-21.
5. AC POWER SWITCH/CIRCUIT BREAKER:
The SA-4200 amplifier has a combination AC switch/circuit breaker on the front panel. If the switch shuts
off during normal use, push it back to the ON position once. If it will not stay on, the amplifier needs
servicing.
6. COOLING AIR VENT:
The SA-4200 is designed to operate under extreme conditions. Part of this design includes the air vents
visible from the front of the unit. These openings should never be blocked.
