1. 

Record level

録音レベル
(BALANCE)

ANALOG INPUT
(BALANCED):

1 kHz, +20 dBu

Rotate  the  INPUT  (L,  R)  controls  to  positions  at  which  the
"OVER"  segments  of  the  level  meter  is  just  about  to  light.
AT this tine, the output level should be +20 dBu ±2 dB.

INPUT (L,R)つまみを回して、レベルメータの OVER が
点灯する直前になるようにセットする。
このとき、出力は +20 dBu ± 2 dBであること。

INPUT SELECT: Balance

Record level

録音レベル
(UNBALANCE)

1 kHz, +6 dBV

Rotate  the  INPUT  (L,  R)  controls  to  positions  at  which  the
"OVER"  segments  of  the  level  meter  is  just  about  to  light.
AT this tine, the output level should be +6 dBV ±2 dB.

INPUT (L,R)つまみを回して、レベルメータの OVER が
点灯する直前になるようにセットする。
このとき、出力は +6 dBV ± 2 dBであること。

Do  not  vary  the  INPUT
control  positions  after  the
adjustment.  (These  are
their specified positions.)

調整後、INPUTつまみは動
かさないこと。
