<제품특징>

· NexSys-ready

· toroidal power transformer

· tunnel cooling

· variable speed DC fan

· high thermal mass heat sinks

· balanced XLR inputs

· 5-way output binding post connectors

· stereo/parallel/bridged mono mode selector switch

· extensive protection circuitry:
o clip limiting prevents speaker damage with gentle gain reduction at clip threshold
o IGM (instantaneous gain modulation) monitors connected loads to detect conditions that may overstress output devices allowing safe operation into nominal 2 ohm impedances
o AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on
o other protection circuitry: comprehensive thermal management; short circuit DC voltage turn-on/off transient current inrush and sub/ultrasonic input protection

· ultra-strong single-piece steel chassis

· octal accessory sockets

· recessed stepped attenuators

· front panel circuit breaker/power switch

· modular construction

· five-year warranty
