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 fi le 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-se-
lected actions: 
•  no action, 
•  new cue - cue markers are set within the fi le being written, 
•  new fi le - a new fi le 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 fi le will be 
corrupted and there is a possibility of FAT corruption as well. 
Playback 
Just like a “tape recorder”, pressing play will begin fi le playback. The 744T has high-resolution play-
back circuitry and is appropriate for any reference audio application. Any fi le recorded by the 744T 
can be played back, including all uncompressed audio fi les and MP3 fi le playback. In addition, fi les 
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 fi le unless another fi le is selected. There are two ways to 
select another fi le for playback. To select another fi le in the current record directory, push either the 
FastForward or reverse key to put the 744T in to play-stop mode. The fi lename display will begin 
fl ashing and the FastForward and Reverse keys are used to step through fi les available in the current 
record directory. To select a fi le in an alternate directory, press the HDD key to enter the media direc-
tories. Navigate to the appropriate directory. Select the fi le that to play back with the Multi-Function 
Controller and press play. 
If the stop key is pressed while playing fi les from an alternate directory, the 744T will revert to the 
current daily directory.
