AC POWER SWITCH
1
This switch provides power to the amplifier.
INDICATORS
2
The Pro-LITE amplifiers feature five front-panel LED indicators per channel: ACTIVE, DC, TEMP, SIGNAL, and ACL
®
These LED indicators inform the user of each channel's operating status and warn of possible abnormal conditions.
ACTIVE LED
3
The Active LED indicates that the channel is operational. It lights under normal operation and remains on. If the Active
LED goes off, there is no signal at the output connectors.
DC LED
4
In the event of abnormal operating conditions, the Pro-LITE has built-in amplifier protection. Under conditions that
would normally damage the power amplifier, the DC LED will illuminate and the amplifier will automatically attempt
to restart to correct the condition. If the amplifier does not return to normal operating status, contact your local
authorized service center.
TEMP LED
5
In the unlikely event of an unstable thermal condition, amplifier protection will be activated and will shut down the
offending channel.
The Temp LED will remain illuminated until a safe operating temperature has returned.
SIGNAL LED
6
This LED lights when its channel produces an output signal of about 4 volts RMS or more (0.1 volt or more at the
input, with 0 dB attenuation and standard x 40 voltage gain). This signal indicates whether a signal is reaching and being
amplified by the amplifier.
ACL™ (Automatic Clip Limiting) LED
7
A channel's ACL LED will light at the onset of clipping. If the LEDs are fl ashing quickly and intermittently, the channel is
™
just at the clip threshold. A steady, bright glow means the amp is clip limiting or preventing severely clipped waveforms
from reaching the loudspeakers. During initial power-up the ACL
INPUT ATTENUATORS
8
Whenever possible, set the attenuators fully clockwise to maintain optimum system headroom. The input
attenuator controls, located at the front panel (one for channel A, one for channel B), adjust gain for their
respective amplifier channels in all modes. See the specifications at the end of this manual for standard voltage gain
and input sensitivity information.
