PRA-AD604
PRAESENSA Amplifier, 600 W 4-Channel
600 W, 4-channel networked power amplifier for 100 V / 70 V loudspeaker lines in Bosch PRAESENSA PA/VA systems, with flexible power sharing, per-channel DSP and integrated spare channel.
Description
The PRA-AD604 is a compact four-channel power amplifier for 100 V or 70 V loudspeaker systems in PRAESENSA public address and voice alarm installations. Its 600 W of output is shared flexibly across the four channels, so each channel uses only the power its loudspeaker load needs.
Each channel has its own digital signal processing, and the amplifier is fully supervised with integrated fail-safe redundancy, including a spare channel that takes over automatically. Low power consumption and heat loss keep battery and cooling requirements down. It is powered at 48 V DC from a PRAESENSA multifunction power supply.
Trinity Solutions supplies, programmes and commissions Bosch PRAESENSA public address and voice alarm systems across the UAE, including integration with fire alarm, IP telephony and BMS.
