1 AUDIO INPUT (AUTO/MANU) switch
Switches the audio recording level adjustment mode.
AUTO: Adjusts the recording level automatically.
The AUDIO REC LEVEL control knobs (CH-1 to
CH-4) 2 are disabled.
To link the AGC (Auto Gain Control) of the audio
channels (CH-1/2 or CH-3/4), set AGC CH1,2
(AGC CH3,4) on the AUDIO SET menu to
LINKED.
MANU: Enables the AUDIO REC LEVEL control

Notes
• When DV signals are input to the unit, the sound
recorded retains the signal level input, regardless of
the setting of this switch.
• If the sound is louder than the input amplifier’s
dynamic range, the AUTO setting is ineffective.
• Even if you set this switch to AUTO, unless the
setting of the INPUT LEVEL selector on the rear
panel is appropriate, there may be clipping and noise.
• The audio level is automatically adjusted to an
appropriate level when you select AUTO. It takes
about 20 seconds for the audio level to be stabilized
in the following cases.
– immediately after powering on
– immediately after stopping a playback operation
– immediately after switching the audio mode in
AUDIO MODE on the AUDIO SET menu
• If LIMITER on the AUDIO SET menu has been set
to ON while you are manually adjusting the audio
level, you can record the sound without clipping even
if the audio input level is high as long as the level is
within the amplifier’s dynamic range. The LIMITER
setting is available only when this switch is set to
MANU.
2 AUDIO REC LEVEL control knobs (CH-1 to
CH-4)
By turning these knobs, you can adjust the analog
audio input signal levels for CH-1 to CH-4
respectively. You can adjust the audio signal level only
if the AUDIO INPUT (AUTO/MANU) switch 1 has
been set to MANU.
To display the audio levels meters on the LCD
monitor, set the DISPLAY SELECT selector on the
monitor display section to AUDIO (audio screen).
While you are holding down the FINE (fine audio
levels) button when the audio levels meters are
displayed, a part of the audio levels meters will be
enlarged (Fine audio levels screen). To select the
enlarged portion, use REF LEVEL on the AUDIO SET
menu. You can adjust the audio levels precisely on this
screen.
For details on the audio screen, see “Audio screen” on page
28 (GB).
Note
You cannot adjust the audio level of the DV signal.
