Vocia VA-8600c

The Vocia VA-8600c is a digital networked multi-channel amplifier for use in Vocia® systems. The VA-8600c is CobraNet® enabled and can support up to eight modular AM-600c amplifier cards. These are individually software configurable from 100–600 Watts per channel up to a maximum of 2400 Watts of power per chassis. 70V, 100V and low-impedance outputs are software selectable per card. The  amplifiers can be configured for channel-to-channel or device-to-device failover. The amplifier uses comprehensive fixed-chain digital-signal processing within the device, including volume control, ducking, equalization, compressor/limiter, speaker crossover, delay, and output gain. Emergency messages for life-safety compliant systems are stored in non-volatile memory within the VA-8600c. Intuitive software provides audio system design via PC. Two RJ-45 connectors on the rear panel of the VA-8600c provide redundant connectivity to control data and audio over a single Ethernet cable and caters for an optional page active relay or dual 3:1 / 7:1 failover module. As part of the Vocia system, the VA-8600c used with the AM-600c compliant amplifier modules meets EN 54-16 certification for facilities of all sizes.
