Specification
Reference
Sheet
• 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

EATURES
• 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
