2.5.12 Amplifier Chassis
The Amplifier Chassis is an industrial grade, high-efficiency Class D amplifier that is
designed for Public Address and General Alarm applications. (See Figure 12.) It can
deliver full power at temperatures from -10 to +55°C.
The Amplifier Chassis contains up to four, 300 W amplifier cards that share two common
motherboards. (See Figure 13.) The front motherboard is a signal router board, while
the rear motherboard is a power connection board. An optional Intelligent Monitoring
and Tapping (ISMT) card may be inserted into the chassis on the right side of the signal
router motherboard.
The Amplifier Chassis’s daughter cards, modules, and backplanes are listed in Table 14.
