744T User Guide and Technical Information

Routing Inputs to Tracks

Before recording, inputs must be assigned to tracks. Each of the 744T’s four inputs (1, 2, 3, 4) can be assigned to any of the four tracks (A, B, C, D). These sixteen possible routing combinations are shown on the front panel with 16 blue LEDs. Illuminated LEDs indicate input-to-track assignment.

1.Press the input key to cycle through factory routing presets. The 744T has six often-used presets for quick setup of input-to-track routing combinations. Note the routing combinations on the blue LEDs with each successive press.

2.If none of the preset routing combinations are suitable, assign a custom routing. Sequential presses of the input key will eventually cycle to the custom routing option (see Input to Track Routing, pg. 18).

3.Press Exit to leave input routing mode.

The custom input routing menu allows any input to be assigned to any track. Multiple inputs can be assigned to a single track.

Recording Parameter Setup

For most productions, the general recording parameters of sample rate, bit depth, media selection, and file format are changed infrequently. Enter the setup menu to verify recording settings. Sample rate and bit depth are displayed on the LCD panel.

1.Select the bit depth as needed.

2.Set the sample rate as needed.

3.Select the file format for recorded files.

4.Select the storage medium (internal hard drive, Compact Flash, or both) for recording.

Time Code Setup

When using a time code workflow, proper time code setup is essential. Skip this section if time code is not being used.

1.Select a time code frame rate appropriate for your project. For film, typical the time code rates are 30 fps non-drop (US) or 25 fps (EU). For standard definition video projects, use either 29.97 or 29.97 non-drop. For high-definition projects, use either 23.976 or 29.97.

2.Select the time code run mode: free run, continuous jam, record run, or 24 hr. run.

3.Use the 744T as the master clock source and jam time code to all other recording devices. This will assure that every device is using the same time reference. (See Time Code for additional information on time code setup).

Recording

Now that file basics are set, you are ready to begin recording. The 744T is a record-priority box. Pressing the record key cancels all functions—except file operations—and immediately starts recording a new file. When record is pressed, the red record LED illuminates to confirm record mode. The

filename in the LCD display shows the currently recorded file. Push the stop (150 ms) key to end recording.

Playback

When recording is stopped, the most recently recorded file is immediately available for playback.

Press the key to begin file playback from the beginning of the file.
