(Note: the 722 will not provide T power for older
Sennheiser mics.)
Adjust your mic level(s) with GAIN control(s) 1 & 2

Transferring Files to Computer:
Files are transferred via Firewire. The 744T will
show up on your computer like any other Firewire
drive.
After 1 day, you should see something like this:
1. Turn on the computer and the 744T.
2. Connect your computer's Firewire cable to the
port on the right panel of the 744T.
3. Make certain that menu item 2: FIREWIRE:
CONNECTION is set to COMPUTER /CONNECT. Otherwise, it will think that your computer
is just a hard drive.
When successfully connected via FireWire. When
connected, all audio functionality of the 744T is
defeated.
Each day of recording creates a new folder on the
722.
Copy the files to your media drive.
Eject the drive from your computer.
Disconnect the Firewire cable.
Battery Removal:
Push the small silver button with a pen
or paper clip and slide the battery to the
right.
This guide is just a basic overview. Much important information has been left out. It is not a substitute for
proper instruction or practice
It is very important that you plan your entire post-production path BEFORE you start recording.
Please see the 722 User Guide for more complete information.
