When you set the AUDIO INPUT LEVEL 
switch: 
• You do not know how to adjust the input 

level.

• The recorded level is too low.
• The recorded sound is distorted.

Confirm the level of the sound output from the player by referring to the player’s 
instruction manual. According to that output level, set the AUDIO INPUT LEVEL 
switch on the rear panel of the unit so as to obtain an optimum level (page 16).
If you are not clear about the player’s output level, try the following procedures.
1

Set the AUDIO INPUT LEVEL switch by types of audio output connectors 
available on the player. 
• If the player is equipped with phone jacks: –10.
• If the player is equipped with XLR connectors: +4 or –2.

Set the AUDIO INPUT switch on the front panel to AUTO and play back the 
tape which you intend to use for playback. When the playback audio level is at 
its maximum, if the audio level meters exceed 0 dB, set the AUDIO INPUT 
LEVEL switch to the lower step (+4). Or, set AUDIO INPUT switch to MANU and 
turn the AUDIO REC LEVEL control knobs to adjust the recording level. The 
recorded sound at the portion where the meters exceed 0 dB will be distorted.

32 kHz audio mode (4-channel) (page 63). If the unit detects the following, 
audio dubbing will automatically abort, an alarm message will be 
superimposed on the LCD monitor and on an external monitor (page 91).

onto channels 1 and 2.

from the HDMI OUT jack, AUDIO OUT 
jacks, or i (phones) jack.

• Set the AUDIO OUTPUT SELECT switch depending on the audio channel you 

want to output the sound to (page 7). For the output from the HDMI OUT jack, i 
(phones) jack or speaker, also check the setting of [AUDIO MONI] in the [AUDIO 
SET] menu (page 76).

display any image.
