Audio Rec

Used for selecting the method of recording audio, 12 bit (12bit/32kHz) or 16 bit

(16 bit/48kHz). 16 bit audio recording is preferred.

Mic ALC

This item Allows the user to turn ON or OFF the automatic level control for the

Microphone.

Mic Gain 1

This item allows the user to select the input level of the external microphone

that is connected to INPUT 1 connector. Either –50dB or –60 dB, see your MIC's specs.

Mic Gain 2

This item allows the user to select the input level of the external microphone

that is connected to INPUT 2 connector. Either –50dB or –60 dB, see your MIC's specs.

Time Code

A Time code is used for accurate video editing of the recorded video tape. A

special internal generator will place an 80 bit code or number on every recorded frame. The

VCR will use this number for precise identification of a frame when editing. This code is re-

corded with the video and audio signals and is stored in the sub code area on the DV tape.

This code contains the hour, minute, second and frame number.

In the 80 bits of time code you have a lot of information, such as drop frame information,

color frame information and user bit information.

The drop frame is used to keep accurate timing between the vertical timing and the actual

time. The drop frame is bit number 10, this bit identifies if the drop frame or the non-drop

frame format is being used. If it is "1" the unit is placed into the drop frame mode and will

account for the missing frame numbers which are missing due to the timing of the vertical

and time. If it is "0" it will be placed into the Non-drop Mode. In the 24p mode we use NDF

only.

There are 32 User Bits in each 80 bit code, these user bits can be used to identify the user

information, the time, the date, the time code generators value, or the frame rate..

There are two ways to start recording time code, record run and free run. Normally, for

most productions the VCR's time code is set to the Record run mode. In this mode the

time code will be set to zero at the start of the day's recording (operates only during record)

and a continuous record is produced on each video tape covering all takes. In the free run

mode the time code is running regardless of the VCR's operation mode.

TC Mode

This item selects DF (Drop Frame) or NDF (Non-drop Frame) modes and as

explained this item corrects timing differences.

Note: When the progressive mode, 24P or 24P ADV is used, the non drop frame mode is

set regardless of the setting.

TCG

This item selects FREE RUN OR REC RUN, For continuity, its best to leave in the

REC RUN mode.
