Page 2: Table Of Contents
The PA8 8 Channel Power Amplifier is a unigue single rack-space solution for zoned, distributed loudspeaker systems with eight separate power amplifiers, each with an output power capability of 10W (4 Ohms) or 6W (8 Ohms.) The PA8 is passively cooled, and features full short-circuit and thermal overload protection. The amplifier outputs are muted at turn-on and turn-off, to eliminate transients. -
Page 3: General Technical Description
GENERAL TECHNICAL DESCRIPTION The PA8 uses a straightforward, low parts count design for long term reliability. The heart of the power supply is a low radiation toroidal transformer. The toroidal transformer generates less heat than a comparable non-toroidal type, and emits considerably less 60Hz energy. -
Page 4: Installation
INSTALLATION Installing the PA8 properly is simple, and only requires attention to a few issues. The PA8 should be used in a grounded metal rack. One open rack space should be provided above and below the PA8 for proper ventilation. Shown below are the connections for both non-bridged and bridged operation. -
