Setting up DVW790 to record cam mic to tracks 3 and 4

Hi everyone
Does anyone know how to set up a sony dvw790 so that the camera
mic is always recorded to tracks 3and 4.I know this is possible but i
think it is set up via the engineering menu and as i do not have an
eng manual with me i an reluctant to start start switching blind.The
reason for doing this is that i am sending audio to the camera via a
radio link (2x Audio 2020) and i dont want the DP messing around with
switches when he wants to use the camera mic.
Many Thanks

you need volume 1 of the maintains manual

5.1 Format

Digital Betacam format VTRs are capable of recording 4 channels of digital
audio. All channels are independently editable, unlike for instance the FM
tracks on Betacam SP.
It uses a 48kHz 16 bit sampling system. Pre-emphasis may be switched on via
the VTR menu, but is factory set to OFF.
The '709 and '790 can also be configured to record the front camera mic.
input onto channel 3, via an automatic level control circuit. Details of the
various configurations can be found in volume 1 of the maintenance manual,
page 3-28. (Beware of making rude remarks about the director if this feature
is enabled! )

5.2 Levels

Headroom is factory set to 20dB This means that 0dB tone from a portable
mixer should be set to -20dB on the input level meters on the camcorder,
using the manual level controls.
Headroom can be modified to 18dB or 16dB using internal switches.

There is a further audio input level control on the front of the camcorder
body. This is normally only in circuit when the camera mic. is selected, and
will not affect any signal input to the channel 1 and 2 inputs on the back
of the camcorder.
An internal tone generator may be switched on via the VTR menu, which sends
1kHz tone direct to tape at -20dB when colour bars are selected.

5.3 Monitoring

Stereo monitoring is available via the 5 pin XLR on the back of the
camcorder. (Pin connections on page 1-11 of the maintenance manual.)
The mini-jack connector can be used to monitor either channel or a mix, but
not stereo.
A 'beep' tone can also be enabled via the VTR menu that warns of REC start /
stop. See page 3-30 of the maintenance menu.

5.4 Recording to channels 3 and 4

The CA-701 camera adapter gives access to all 4 channels with individual
level control monitoring and metering for each channel. This unit also gives
SDI output of E-E or replayed pictures complete with 4 channels of embedded
digital audio.
