CONTINUOUS AVERAGE POWER OUTPUT INTO 8 OHMS OR 4 OHMS (Min. power per channel, 20 Hz – 20 kHz, both channels driven, with no more than rated distortion)
= 150 W (21.8 dBW)
Rated Distortion (THD 20 Hz – 20 kHz)

ALIGNMENT PROCEDURE (C272) I. INITIAL ADJUSTMENT (No load connected) A. OUTPUT OFFSET VOLTAGE 1. Connect a DC Millivoltmeter to L Channel TP2 (DC) and TP8 (GND). 2. Turn unit “ON” and adjust VR301 (100ohms) to get a reading of 0V+/-30mV. 3. Connect a DC Millivoltmeter to R Channel TP5 (DC) and TP7, then adjust VR401(100ohms) to get a reading of 0V+/-30mV reading on meter. B. IDLING CURRENT 1. Connect a DC Millivoltmeter to L Channel TP1 (IDL) and TP3 (IDL), then adjust VR302 (500 ohms) for 6~7.5mV reading on meter. 2. Connect a DC Millivoltmeter to R Channel TP4 (IDL) and TP6 (IDL), then adjust VR402 (500 ohms) for 6~7.5mV reading on meter. II. ISC ADJUSTMENT (WITH LOAD CONNECTED) 1. Connect a DC Millivoltmeter to Power Board CB725, and connect 4 ohms load to both L&R speaker output terminals. Then feed 20kHz signal to Fixed In RCA. 2. Turn unit ”ON” and try to get 15W on speaker output terminal. Then adjust VR701 (82kohms) to get a reading of 0V+/-10mV. 3. Change the load to 8 ohms and try to get 160W on speaker output terminals. Then adjust VR701 (82kohms) to get a reading of 1.4V+/-30mV.
III. FINAL ADJUSTMENT Repeat procedure A and B for offset voltage and idling current alignment respectively.
