Specification Biasing mode: Class A Rated power: 60 W RMS into 8R (20 Hz to 20 kHz) Transient delivery: 150 W into 8R Harmonic and intermodulation distortion: less than 0.06% at rated power output (20Hz to 20 kHz), decreasing monotonically with decrease in power. Distortion is virtually unmeasurable at small signal levels. Frequency response: 10 Hz -1dB 120kHz -6dB (ref 0 dB at 1 kHz) Power bandwidth: 5 Hz to 60 kHz Hum and Noise: 100 dB below 24 V RMS output (CCIR) Sensitivity: 700 mV RMS for 60 W into 8R Negative feedback: the open loop gain is reduced by 22 dB by the application of overall negative feedback Transient intermodulation distortion: zero
