744T User Guide and Technical Information

Recording

The largest, most easily accessed control on the 744T is its record key. Recording takes priority over all activity except for disk formatting, disk speed tests, and file transfers. The 744T will immediately enter record mode whenever the record key is pressed. When recording, the adjacent red LED will illuminate to indicate that the unit is in record mode.

If no inputs are routed to tracks, recording cannot take place. Make certain that at least one record track is assigned for recording.

While recording, the power, ff, rew, input, tone, and drive keys are disabled. Recording is stopped by pressing and holding the STOP key. The Stop key must be held for at least 150 ms to end recording. Although you can enter the setup menu during recording, menu items that will affect recording are lined out in the menu list.

When using the recorded track monitor selection, there is a sample rate dependent delay in the signal. At 48 kHz sampling, the delay is approximately 12 seconds. This delay is due to the record buffering topol- ogy. Audio can not be monitored until it has left the record buffer and written to the recording media.

During recording, subsequent presses of the record key can perform one of three setup-menu-selected actions:

•no action,

•new cue - cue markers are set within the file being written,

•new file - a new file is started with each press of the record key, the take counter is increased by one.

When removing the CF from the 744T, always observe the amber activity LED for the CF medium. If it is lit, wait until it goes out before removing the CF. If you remove the CF while the LED is lit, the file will be corrupted and there is a possibility of FAT corruption as well.

Playback

Just like a “tape recorder”, pressing play will begin file playback. The 744T has high-resolution playback circuitry and is appropriate for any reference audio application. Any file recorded by the 744T can be played back, including all uncompressed audio files and MP3 file playback. In addition, files copied to the storage mediums from a computer can be played back. This is useful when using the 744T as a high-resolution playback device.

The 744T plays back the last recorded audio file unless another file is selected. There are two ways to select another file for playback. To select another file in the current record directory, push either the FastForward or reverse key to put the 744T in to play-stop mode. The filename display will begin flashing and the FastForward and Reverse keys are used to step through files available in the current record directory. To select a file in an alternate directory, press the HDD key to enter the media direc- tories. Navigate to the appropriate directory. Select the file that to play back with the Multi-Function Controller and press play.

If the stop key is pressed while playing files from an alternate directory, the 744T will revert to the current daily directory.
