10. Channel 2 Overheat Indicator (A-2000 only) -
This indicator will
begin to glow when the channel goes into thermal protection mode.
When the unit goes into thermal protection, channel output will turn off.
This is to protect any speakers connected to the channel.
11. Channel 2 Protect Indicator -
The red Protect LED will begin to glow
when the channel goes into protect mode. When the channel goes into
protect mode all output for that channel will turn off. This is to protect
any speakers connected to the channel.
12. Channel 2 Clip Indicator -
This red LED will begin to flash when the
channel begins to overload (clip), at this point the channel will begin to
distort. Under heavy clipping activity lower the channel’s gain control
to reduce the risk of damage to your speakers and amplifier. This LED
may glow when the unit has been turned off, this is normal.
13. Channel 2 Limiter Switch -
This is used to activate the channels built-
in limiter. The limiter reduces the average input level when the signal
begins to distort, this process is designed to reduce distortion and
protect the speakers. See limiter at page 14.
14. Channel 2 Gain Control -
This rotary knob is used to control the output
signal of channel two. Turning the knob in clockwise direction will
increase signal output.
15. Fan Inlet Grills and Filter
- A Series amplifiers are cooled by two rear-
mounted fans. Cool air from front grills is filtered and flows over the
heatsinks and exhausts to back side. Make sure these outlets remain
clear to allow unrestricted air flow.
16. Channel 2 Signal Indicators -
These green and yellow LEDs will glow
according to the average signal output.
