2. INDICATION LEDS
Mains LED for incoming mains supply and Protect LED is to indicate if the unit is switched to protection mode. Clip LED
shall lit if the incoming signal is too high whereas others to indicate signal level in two level ie. -40 dB and -10 dB.
3. FRONT VENT
External cool air enters the unit from these vent holes. Please ensure that there is sufficient clearance for ventilation.
4. DC SUPPLY
For connection of back up 24V DC supply from batteries. Two ports are available for parallel connections.
5. SPEAKER OUTPUT
Outgoing terminals to speakers are available in 4 Ohm, 70 and 100V line for usage with transformer coupled speakers. The
total speakers combined should have impedance higher than stated in the corresponding output terminals to avoid
overloading.
Loudspeakers with suitable matching transformer can be connected to the 70 or 100V line outputs in parallel. However the
total load should not exceed the nominal power output rating of the amplifier.
Do not parallel two power amplifiers in order to gain higher power rating as this may cause overloading in the event that any
one of them failed.
