FEATURES

TECHNICAL FEATURES

•Trans•ana – Sound quality topology that sends an extended bandwidth accurately to the output stages of the amplifier

•TOPAZ – Eliminates troublesome ground loop noise between the source and amplifier

•NOMAD – Extremely fast protection system that always protects the amplifier and never degrades the sound

•MOSFET Devices – Power supply and output devices that have high thermal stability, fast switching speed, low output impedance, and wide bandwidth linearity

•DSM (Discrete Surface Mount) Technology – Fewer connections, improved reliability, shorter signal paths, superior signal-to- noise ratio and awesome sonic performance

DESIGN FEATURES

•Diecast Heatsink – Dissipates heat generated by the amplifier’s circuitry

•Gold-Plated RCA Input Jacks – Maintains signal quality by resisting corrosion

•Input Sensitivity Control – Level control can be adjusted to match output levels from a variety of source units

•Gold-Plated Power/Speaker Barrier Strip – Screw terminals accept #10 spade lugs or bare wire sized from 10 to 18 AWG

•Crossover Switch – Crossover can be set for low-pass operation or full range

•Bass EQ – The Bass EQ allows a narrow band adjustment of up to +18dB centered at 45Hz. The bass boost can be bypassed by turning the control to its minimum or counterclockwise position

•LED Power Indicator – Visual indicator illuminates when amplifier is turned on

WARRANTY

•3 Years
