ADJUSTMENT
Audio Section
Idling Current
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)
OFF
• SPEAKER (Speaker terminal)
No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) Remove top cover and set VR101 FL, FR, C, SL, SR,
on Main Amp. Unit, VR401, VR402 on 2ch- Amp. Unit
at fully counterclockwise (
c
) position.
(2) Connect DC Voltmeter to test points (FRONT-Lch:
TP101, FRONT-Rch: TP105, CENTER ch: TP103,
SURROUND-Lch: TP102, SURROUND-Rch: TP104,
SURROUND-BACK Lch: TP401, SURROUND-BACK
Rch: TP402).
(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
: 7CH STEREO (5CH STEREO)
FUNCTION
: CD
(5) Within 2 minutes after the power on, turn VR101 clock-
wise (
x
) to adjust the TEST POINT voltage to
1.5 mV ± 0.5 mV DC.
(6) After 10 minutes from the preset above, turn VR101 to
set the voltage to
2.0 mV ± 0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the
same way.

アイドリング電流の調整
調整に必要な測定器 : DC Voltmeter
1. 準備
(1) セットをクーラ、扇風機のそばなど風通しの良い場
所を避け、通常の使用状態に置きます。セットの周
囲温度は 15 〜 30 ℃、湿度は常湿とします。
(2) プリセット
・電源スイッチ
OFF
・スピーカ端子
無負荷
( スピーカ・ダミー抵抗器などを接続しない。)
2. 調整
(1) 上カバーをはずし、メインアンプ基板の VR101 FL,
FR, C, SL, SR 及び 2ch- アンプ基板の VR401,VR402 を
反時計方向 (
c
) に回し切った状態にセットします。
(2) テストポイント (FRONT-Lch: TP101, FRONT- Rch:
TP105, CENTER ch: TP103, SURROUND-Lch: TP102,
SURROUND-Rch: TP104, SURROUND-BACK Lch:
TP401, SURROUND-BACK Rch: TP402) に DC
Voltmeter を接続します。
(3) 電源コードを AC100V(95 〜 105V の範囲でも可)
に接続し、電源スイッチを "ON" にします。
(4) ON 後、次のようにセットします。
・MASTER VOLUME(音量調節つまみ)→反時計方向
(
c
) に回す、最小の状態にする。
・SPEAKER(スピーカ端子)→無負荷(スピーカ、
ダミー抵抗器などを接続しない。
)
MODE : 7CH STEREO (5CH STEREO)
FUNCTION : CD
(5) 2 分以内に VR101 を時計方向 (
x
) に回しテストポイ
ントの電圧を次のように調整します。
1.5mV ± 0.5mV DC
(6) 予備調整から 10 分後 VR101 を回し、次のように電
圧を設定します。
2.0mV ± 0.5mV DC
(7) 同じ方法で各チャネルの可変抵抗を調整します。
