Supply voltage range : DC + -25V -- + -55V. It is recommended to use a voltage DC + -40V.
Output power : 50-150W 8 ohms
Output voltage gain : 18 times
Front and rear stage combined output gain (switchable with preamp output mode) = 100 times
Switch pin pins PREAMP OFF = 1-2 for pure post-stage output, PREAMP ON = 2-3 fore-stage combined output
Quiescent current, regulation IQ TEST test 2 points voltage is 1MV quiescent current is 13MA
Output DC offset voltage (midpoint DC voltage) < 1.5MV (using DC servo circuit)
Frequency response range = 20HZ -20KHZ (-0.1 DB). 10 HZ-30K HZ -0.2DB
THD+N = 0.005% - 0.008% 15W output 8 ohm load 20HZ-20KHZ
