Figure 12. Stereo reverse mode

Channel A output is connected as in the normal stereo mode. By having

channel A and B operating in opposite polarity, the energy storage in the

power supply is more efficient. This means that the amplifier can deliver up

to 10% more power than in tandem mono mode. This is significant for

signals below 100Hz (sub bass etc.).

7 OPERATION

7.1 Operation precautions

• Make sure that the power switch is off before making any input or

output connections or operating the switches on rear panel. See pages

6-11 about installation.

• Make sure that the AC mains is correct and the same as that printed on

the rear panel of the amplifier. See pages 6-8 about operating voltage

and power consumption.

• Make sure that the switches on the rear panel for operation modes,

clip limiters and the MLS™ switches are in the correct position.

See pages 13 and 14 about operation modes, page 16, about clip

limiters and page 12 for the MLS switches.

• It is always a good idea to turn down the gain controls during power up

as this prevents speaker damage, especially if there is a high level

signal at the input.

7.2 Powering up - Soft start

When you power up the amplifier it takes a couple of seconds to self check.

This is known as the "soft start" or "slow start" sequence. The fans then

blow at high speed before going into "idle" and the two bottom green LED's

illuminate to show the amplifier is operational.
