Required measurement equipment: DC Voltmeter
1. Preparation
(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room temperature
15 °C ~ 30 °C (59 °F ~ 86 °F).
(2) Presetting
• POWER (Power source switch) STANDBY
• SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) Remove top cover and set VR401, VR402, VR403, VR404, VR405, VR406, VR407 on 7CH AMP UNIT at fully
counterclockwise (
c
) position. (AVR-1611 E3 model)
(1') Remove top cover and set VR401, VR402, VR403, VR404, VR405, on 5CH AMP UNIT at fully counterclockwise (
c
)
position. (with out AVR-1611 E3 model)
(2) Connect DC Voltmeter to test points (FRONT-Lch: TP401, FRONT-Rch: TP402, CENTER ch: TP403, SURROUND-
Lch: TP404, SURROUND-Rch: TP405, SURROUND-BACK Lch: TP406, SURROUND-BACK Rch: TP407).
(3) Connect power cord to AC Line, and turn power switch "ON".
(4) Presetting.
MASTER VOLUME : "---" counterclockwise (
c
min.)
SPEAKER (Speaker terminal) : No load
(Do not connect speaker, dummy resistor, etc.)
MODE : MCH STEREO
FUNCTION : DVD
(5) Within 2 minutes after the power on, turn VR401 clockwise (
x
) to adjust the TEST POINT voltage to
1.5 mV ± 0.5 mV DC.
(6) After 10 minutes from the preset above, turn VR401 to set the voltage to 2.0 mV ± 0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
