Operation
5.1 Operation Precautions
To prevent electric shock hazard, ensure that the power switch is set to ‘Off’ before con-
necting any input or output, or operating the switches on the rear panel, and that the con-
ductive parts of the speaker wires are not exposed. See Chapter 3 for installation
information
Ensure that the AC mains voltage is correct and the same as the one printed on the rear
panel of the amplifier. See Chapter 3 for information about operating voltage and power
consumption
Ensure that the switches on the rear panel for operation modes and the clip-limiter
switches are in the correct position. See Chapter 2 for information about operation modes,
and “Indicators” on page 18 for information on clip limiters
It is always a good idea to turn down the gain controls during power-up, to prevent speaker
damage in case a high signal is present at the input
5.2 Powering Up – Soft Start
When you switch on the amplifier, it takes a couple of seconds to check its circuits. This is
known as the “soft-start” or “slow-start” sequence. The two bottom, green LEDs illuminate
to show the amplifier is operational.
5.3 Input Attenuators
The two input-level attenuators on the front panel adjust the signal level for their respective
amplifier channel in all modes. They are calibrated in dB to help setting up active loud-
speaker systems or cutting down unwanted noise from the input signal. See Specifications in
Chapter 9 for more details.
In bridged mode, both controls must be in the same position so that the speaker load is
shared equally between the channels.
