1AC POWER SWITCH/CIRCUIT BREAKER

The PV® 3800 amplifier has a combination AC switch/circuit breaker on the front panel. If the switch shuts off during normal use, push it back to the ON position once. If it will not stay on, the amplifier needs servicing.

INDICATORS

The PV 3800 amplifier features three front panel LED indicators per channel: DDT™, SIGNAL and POWER. These LED indicators inform the user of each channel’s operating status and warn of possible abnormal conditions.

2DDT (DISTORTION DETECTION TECHNIQUE) LED

A channel’s DDT LED will light at the onset of clipping. If the LEDs are flashing quickly and intermit- tently, the channel is just at the clip threshold. A steady, bright glow means the amp is clip limiting, or reducing gain to prevent severely clipped waveforms from reaching the loudspeakers. See the Distortion Detection Technique section for more information. During initial power-up the DDT LED will light to indicate that the RAMPUP™ gain reduction circuitry is activated. This prevents sudden signal bursts when the speaker relays are closed.

3SIGNAL LED

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.

4POWER LED

The Power LED indicates that its channel’s output relay is closed and the channel is operational. It lights under normal operation and remains on, even when the channel is in Distortion Detection Technique or DDT gain reduction. These protection features leave the output relay closed. If the Power LED goes off, there is no signal at the output connectors.

5INPUT ATTENUATORS

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 ampli- fier channels in all modes. See the specifications at the end of this manual for standard voltage gain and input sensitivity information.
