19. MASTER RET/SEND
These jacks are used for looping in an equalizer etc. into the master signal
path. The RETurn jacks interrupt the master signal. The SEND jacks can also
be used as master out e.g. for additional power amps.

20. LEFT + RIGHT / MONITOR LED Level Meter
The LED Level Meters show the power modulation of the power amplifiers.
The area from +3 dB to +6 dB indicates risk of overdriving.
Please avoid overdriving. The unit or connected loudspeaker cabinets
could be damaged.
TBC
The short-term peak output power of the PCA power amps is considerably
higher than the rated output power in order to give you excellent dynamic
behaviour. The "dynamic headroom" (IHF-A) is 1.5 dB which is equivalent to
approximately 350 Watts/40hms output power. The TBC circuit contains a
simple 1 s t order voice coil model to simulate the thermal behaviour of a typical
woofer. At continuous overdriving or modulation with square wave signals this
part of the processor reduces the power output to the rated output (250 W / 4
ohms), to protect the connected loudspeaker system against thermal overload
of the woofer’s voice coil.

Please note that speakers with less power capa bllity than the rated power
cannot be protected completely by the "Thermal Brain Circuit".
BUSY
This indicator lights up if the limiter part of the processor is activated.
Continuous lighting of the BUSY LED indicates danger of overdriving the amp
and should be avoided by reducing the output volume.
PROCESSOR ON
These LED's indicate that the unit is ready for operation.
21. STANDBY + LED
By pressing this button you can mute the outputs MASTER L + R and
MONITOR. The red LED will blink and indicates that the complete unit is muted
e.g. during breaks.
22. MASTER L + R
Master volume control for the left and right master output.
For further information see: 50-57. Speaker Outputs
Please make sure that the respective channel fader or at least both master
faders are closed before connecting signal sources, to protect your
audience from annoying click noise.
