Front Panel Description
1.
POWER SWITCH – press to turn the amplifier off:
it turns on automatically on initial application of the
AC supply. The integral white LED illuminates when
the amplifier is powered, either in its active state or in
Automatic Power Down (APD) mode.
Each amplifier channel has four LEDs on the front panel,
which function as follows:
2. POWERED (green) – illuminates when the channel is
active, i.e., it has been "woken up" when the output
signal level exceeds -65 dB relative to maximum output
level (typical threshold: may vary with programme
type).
3. SIGNAL (green) – illuminates when the output signal
level from the amplifier channel is at least 2.5 V
4. PEAK (yellow) – illuminates when the channel's limiter
is active, i.e., reducing gain.

5. PROTECT (red) – indicates a fault condition. It
illuminates when the power amplifier stage is shut
down by the internal protection circuitry, which
will occur if excessive current or DC is detected at
the output terminals, or if the internal temperature
becomes too high. Over-current or DC fault conditions
can be cleared by removing the AC power supply for a
few seconds, but when the cause is over-temperature,
the amplifier will remain in its protected state until the
temperature drops (which will generally occur if the
input signal is reduced).
6. Ventilation intakes – these should always be
unobstructed when the amplifier is in use.
