6.3.2 Set recording levels
Audio levels for the four recording channels are controlled automatically or manually. When
manual control is selected, the two rotary controls at the left-rear of the camcorder are used to
adjust the audio levels. These can be programmed to adjust a single channel or a combination
of channels.
The front audio level control can be assigned to any channel. This control can be used together
with the rotary controls at the rear.
To set up audio level control for each of the four recording channels:
– Go to the AUDIO > CHANNELS menu.
– Tap one of the CHANNEL buttons numbered 1 to 4.
The following buttons appear (for each channel #):
• CH # LVL CONTROL - selects the method to adjust the audio level:
– AGC or AGC-12DB turns on the Automatic Gain Control.
– LEVEL 1/2 is the top control at the left-rear of the camcorder.
– LEV1/2+FRONT takes the average value of the level 1/2 and front audio controls.
– FIXED allows you to set a fixed level for the channel (with FIXED LVL ).
– FRONT is the rotary control at the front of the camcorder.
• CH# FIXED LVL - sets the fixed recording level for the channel when LVL CONTROL is set
to FIXED.
• CH# FILTER - selects a filter that is applied to the channel.
• CH# AGC PROFILE - selects a profile used for the AGC when selected.
Set up these controls for each of the four recording channels. The Level 1 control can be
assigned to channels 1 or 3; the Level 2 control can be assigned to channels 2 or 4.
Automatic Gain Control
When AGC (or AGC-STEREO) is selected the camcorder uses its internal circuitry to
automatically adjust the recording level according to a selectable response profile:
– STANDARD uses a standard response curve.
– QUIET uses a response curve that is suitable for low-volume circumstances, like
concerts or speeches.
– NOISY uses a response curve that is suitable for noisy circumstances like outside,
heavy wind situations or crowds.
