LIMITER indicator
If the output level of signals
received at the SPEAKERS output
jacks (output of the internal power
amplifier) reaches maximum, the
indicator will light.

Block and Level diagram
Power Amplifier output section level diagram (bottom right)
These plots show the nominal output and maximum output
levels of signals received at the SPEAKERS jacks. If the output
level is +4dB (Level Meter “0”), the internal power amplifier
will deliver 60W into a 4
Ω
load. If the output level is +11dB
(LIMITER indicator lights), the internal amplifier will deliver
a maximum of 300W into a 4
Ω
load. If you are using the
BRIDGE jack, the internal power amplifier will deliver 120W
into an 8
Ω
load with a +4dB signal, and a maximum of 600W
into an 8
Ω
load with a +11dB signal.

Note:
The SPEAKERS 1 & 2 jacks (rear panel
1
) out-
put the signals received at the MAIN OUT jack via the
internal power amplifier. Check the output signal level
via the LIMITER indicator (
I
).
Note:
The SPEAKERS 1 & 2 jacks (rear panel
1
) out-
put the signals received at the MONITOR OUT jack via
the internal power amplifier. Check the output signal
level via the LIMITER indicator (
I
).
Caution:
If the LIMITER indicator flashes continuous-
ly, the internal power amplifier section is being exces-
sively overloaded and may malfunction. Reduce the
output level at the Master control (
BG
) below the level
that the indicator flashes only briefly on the highest
transient peaks.
