400 Watt 2-Channel Trans•nova Professional Power Amplifier A powerhouse of nearly 600 watts in a three rack space chassis, Hafler’s award-winning P4000 offers stunning performance that is perfect for studio monitoring, touring, and fixed installations. All this at an even more mind blowing price. 特性 Trans•nova 專利 輸出級
configured for "power gain" allows simpler front end circuitry, dramatically lower cross talk and noise. DIAMOND combines the linearity of Class A with the headroom of Class B; provides up to 14dB additional dynamic range in front end. MOSFET Outputs Deliver higher output current, rugged reliability, superb sound quality. 5.25" Rack Mount (3-rack spaces) Stereo/Bridged Mono XLR or 1/4" Balanced Inputs Gold-Plated 5-Way Binding Posts Power Lamp, Signal, Clip, Thermal, Short LEDs Full Range Gain Controls Chassis/Float Ground Switch Serviceable Channel Modules
