AUDIO/MIC[1/2] Menu

Screen

The AUDIO/MIC menu screen consists of two screens (1/2 screen, 2/2 screen).

In VTR mode, the screen changes to the AUDIO menu screen.

* This is not displayed in VTR mode.

Item		Function/Setting (bold characters indicate initial settings)

	OFF	: A test audio signal is not output.
	ON	: A test audio signal is output.
MIC WIND CUT*	Selects whether to cut the lows (low frequency bands) from the audio input signal.

	–20dB	: Records with –20 dB as the reference audio level.
	–12dB	: Records with –12 dB as the reference audio level.
		Set this if you are playing back the recorded tape on an ordinary DV device.

	(When HDV format is set, this is fixed at 48K and “[48K]” is displayed.)
	32K	: Digitally records with a 12-bit, 32 kHz sampling frequency.
	48K	: Digitally records with a 16-bit, 48 kHz sampling frequency.
	* If the DV format is 12-bit, 32 kHz, up to 4 recording track channels are available.
	Of those, GY-HD250/GY-HD251 records on the CH-1 and CH-2 channels. GY-HD250/GY-HD251 is not capable of
	dubbing.

	to MANU.
	OFF	: AUDIO LIMITER is turned off.
	ON	: AUDIO LIMITER is turned on. Recording level is suppressed when excessive audio is input.
