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  

· rear panel ground lift jumper  

· 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
