UNIVERSAL MOUNTING

17" wide, 5%" high, 9" deep

Ideal for rock mounting with optional FP

Classic styling in the optional enclosure

As a basic amplifier, tucked away, out of sight

UNIVERSAL POWER RANGE

75 watts (R.M.S.) per channel 20-20K

Cleanest power for most hi-fi systems

IC op-amp front end for linear bandwidth and gain

Really quiet performance - drives electrostatic
head phones without pads

UNIVERSAL LOAD MATCHING

Matches any load from 4 ohms to infinity

Offers higher damping factor via Crown-pioneered
AB+B direct-coupled output

New volt-ampere limiting protection is automatic -
eliminates power supply fusing
