CONTROLS
LIMIT
brief blinking indicates that the power ampli er is operated
at its limits. Short-term blinking is uncritical, because the integrated
limiter compensates minor distortion. Constant lighting of the LED
indicates that the sound is negatively affected. Reducing the output
volume is strongly recommended.
SIGNAL
indicates the presence of an input signal.
THERMAL
lights, when the power amp’s output power is reduced to
prevent thermal overload.
PROTECTION
lights, when one of the power amp’s comprehensive
protections against e.g. thermal overload, HF or DC at the output,
and Back-EMF has been activated. The speaker outputs are
deactivated and the input gain is reduced when in Protect Mode, to
protect the power ampli er from damage.
The PROTECT LED lights for approximately 2 seconds during
power-on operation. This is normal, indicating that all protections are
working.
POWER
-switch
Mains switch for powering the appliance on or off. With the power
ampli er being switched on, the mains switch is backlit. If, after
switching the power on, the switch is not backlit, please rst check
whether the mains cord is correctly connected. In case the cord
has been connected correctly and the switch still fails to light (no
function), please contact your specialist dealer.
MAINS FUSE
Under normal circumstance the mains fuse only blows in case of
failure. Always use an identical type with the same current, voltage
and blow characteristics when replacing the mains fuse. If the mains
fuse blows more often, please contact your specialist dealer.
MAINS IN
Mains connector is carried out as PowerCon-type socket. A tting
mains cord (5m) with PowerCon-type plug is supplied.
MAINS OUT
This PowerCon mains out socket allows the connection of additional
MADRAS cabinets, e.g. M15 or M18, using special cords (PC150 or
PC800).
To prevent mains n etwork overload, connecting more than
three MADRAS cabinets to a single mains outlet (10A-16A) is not
recommended.
