2-Channel Punch Amplifier
Punch 100z2Specification
Reference
Sheet
•High Level Inputs – Allows compatibility with a variety of source units
•Gold-Plated RCA Input Jacks – Maintains signal quality by resisting
corrosion
•Independent Sensitivity Controls – Level controls for left and
right channels 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
•80Hz Low-Pass Crossover – Crossover can be set for low-pass
operation or full range
•LED Power Indicator – Visual indicator illuminates when amplifier is
turned on
WARRANTY
•3 Years
FEATURES
TECHNICAL FEATURES
•Trans•ana – Sound quality topology that sends an extended bandwidth
accurately to the output stages of the amplifier
•MEHSA – Very efficient heat dissipation technology
•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
