Rotary Switch Behavior; Headphone Favorite Selection; Headphone Playback Mode; Headphone Warning Tones - Sound Devices 744T User Manual And Technical Information

There are two B-format monitoring selections, one for inputs and one for tracks. They are listed as
INPUT B-FMT STEREO and TRACK B-FMT STEREO. For most recording and playback applications
the track monitor selection is appropriate. If the user wants to hear the inputs at all times, the input
monitor selection is appropriate.

Rotary Switch Behavior

The action of the Rotary Switch during recording and playback is set from among the three available
options:
• Disabled: pushing the Rotary Switch has no effect.
• Selects Favorite Mode: places the headphone source into the mode selected in the HP Favorite
menu.
• Headphones to C/D meters: shows the level of the headphone output on the C/D track me-
ters.
• Playback/Monitor Drive Select: pushing the Rotary Switch toggles between Internal Hard
Drive, CompactFlash, and External Hard Drive for playback and monitoring while recording.

Headphone Favorite Selection

If "SELECTS FAVORITE MODE" is selected from the choices above, pushing the Rotary Switch selects
the assigned "Headphone Favorite" source. This feature is helpful to quickly return to a selected
headphone monitoring selection while recording or playing. One of the available headphone selec-
tion can be selected as the headphone favorite.

Headphone Playback Mode

A single headphone source can be set to automatically activate upon playback. All headphone moni-
tor combinations are available for the Headphone Playback Mode, as well as "No Change", which
makes no change to the headphone selection during playback. Headphone Playback Mode is select-
ed in the setup menu.

Headphone Warning Tones

The 744T can generate an audible beep, or warning "bell", in the headphones when an error has
occurred. The specifi c error will be reported on the LCD. The output level of the warning bell can be
selected from off or –20 to –12 dBFS in the setup menu.
Recording Start and Stop Tones
If activated from the setup menu the start of recording can be indicated audibly by a single, 440 Hz
tone sent solely to headphones. When recording is stopped, two 220 Hz tones play in headphones.
Low Battery Warning
When either the attached battery or external power supply voltage reaches their low warning levels
(6.5 V for the attached Li-ion, 11.0 V or user-selectable for external) warning tones are played in
headphones. The warning tone is a three pop note of 880 Hz every 20 seconds.
If all warning tones are turned off, no tones are sent to headphones, including low battery warning
tones.
