User manual ELECTRO-VOICE CD SERIES 35I

[. . . ] The fans are quiet enough to permit use of the Q44 in noise-sensitive applications such as recording studios and houses of worship. The output devices are mounted to two large, extruded aluminum heat sinks that are engi- neered to minimize thermal gradients and allow the amplifier to operate safely into lowimpedance loads. The output devices have a maximum junction temperature of 200o C (392o F), so high operational temperatures present no problems. The output devices are mounted directly to the heat sinks without mica insulators to ensure better dissipation of heat. [. . . ] Protection circuits guard against overload, over-temperature, shorted outputs, radio-frequency interference and dc faults. The output devices are protected against damage from the reverse feeding of electrical energy (back EMF) from the load and are switched on via relays to avoid transients which could damage speakers. The Q44 has built-in limiters to protect speakers from the deleterious effects of amplifier clipping. The limiter's action is controlled by very sophisticated input/output comparators which are designed to preserve the sonic integrity of the source. The Q44 has electronically-balanced XLRtype input and signal output connectors that allow easy, problem-free connections and signal routing. The amplifier has an input routing switch that allows selection of either normal dual-channel operation or parallel mono operation, which routes an input to both channels but still allows independent level control. The Q44's professional Neutrik Speakon® output connectors provide sturdy, reliable connections and allow use of heavy wire for loss-free signal transmission. There are separate output connectors for channels, A and B, and for the bridge mode. The bridge mode connector is sealed with a plastic cover to prevent connection errors. To prevent ground loops from occurring, the Q44 is equipped with a ground-lift switch.
