INDICATORS
3
The Pro-LITE amplifiers feature five front-panel LED indicators per channel: ACTIVE, DC, TEMP, SIGNAL and ACL
®
LED indicators inform the user of each channel's operating status and warn of possible abnormal conditions.
ACTIVE LED
4
The Active LED indicates that the channel is operational. It lights under normal operation and remains on even when the channel
is in ACL gain reduction. If the Active LED goes off, there is no signal at the output connectors.
™
DC LED
5
In the event of abnormal operating conditions, the Pro-LITE
normally damage the power amplifier, the DC LED will illuminate and the amp 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
6
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 safe operating temperatures have returned.
SIGNAL LED
7
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 x40 voltage gain). This signal indicates whether a signal is reaching and being amplified by the amplifier.
ACL ™ (Automatic Clip Limiting) LED
8
A channel's ACL ™ LED will light at the onset of clipping. If the LEDs are flashing 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™ LED will light.
INPUT ATTENUATORS
9
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.
