1. Carry/protection handle - Both handles can be used to carry the amplifier, they also act
as protection for the front panel.
2. Fan grill filter - A foam filter is located behind the front panel to prevent dust entering the
amplifier.
3. Input level attenuators - These controls are used to alter the signal level entering the
amplifier. They are calibrated to help set up active loudspeaker systems or cut down
unwanted noise from the input signal
4.Clip/limit indicator - This indicator tells when the amplifier output is clipping or limiting.
The two different states can be told apart:
When the clip limiter is engaged it flickers briefly.
When the clip limiter is not engaged it lights for a longer period.
5. VHF protect indicator - This indicator lights when constant signals, above 12KHz at full
power, are present at the output terminals. When this happens the input signal is muted
and the process cycles until the VHF signal is no longer present.
6. Over temperature protect indicator - This indicator lights if the amplifier tries to operate
above its maximum operating temperature (90°C). The indicator first comes on as a
warning to either turn down the input level or check the cooling arrangements after which
point the amplifier will mute the input signal. When the cooling fans have returned the
output heatsinks to the normal operating temperature the input signal is unmuted.
7. Mute indicator - This indicator will light when if a fault condition on the channel. The
possible conditions may be due to overload, overheat, CPL and VHF protection.
8. AC Power switch - This is used to activate the amplifier.
