Description
8-Channel Power Amplifier
The PA8 8 Channel Power Amplifier is a unigue 1 RU solution for distributed loudspeaker systems using mix-mminus zoning. The amplifier is typically used with Lectrosonics matrix and DSP processors for sound reinforcement systems in boardrooms, courtrooms and conferencing systems.
Eight separate power amplifiers, each with an output power capability of 10W (4 Ohms) or 6W (8 Ohms) provide amplification for each loudspeaker or zone-grouped loudspeakers in the system. The PA8 is passively cooled, and features full short-circuit and thermal overload protection. The amplifier outputs are also muted at turn-on and turn-off, to eliminate transients.
The front panel includes a power switch and individual level controls for each channel. The rear panel includes a standard 3-pin AC power socket for IEC 60320 C13 cords. Line level audio inputs and speaker level outputs are made via depluggable "Phoenix" connectors.
Two adjacent channels of a PA8 may be bridged to increase the power output. In the bridged mode, the minimum speaker load is 8 Ohms, and maximum power output is 20W at 8 Ohms. The Channel Level controls are set to the same level in this mode.
Features:
- 8 separate amplifier channels
- 10 Watts per channel into 4 Ohms in non-bridged mode,20 Watts per channel bridged into 8 Ohms
- Passively cooled
- Full short circuit and thermal overload protection
- No turn-on "thump"
