Headphone Playback Mode
The user may select a headphone source for automatic selection upon playback. All headphone
source selections are available for Headphone Playback Mode, as well as “No Change”, which leaves
the headphone source set to the currently selected mode. Headphone Playback Mode is controlled in
the Setup Menu.
Headphone Warning Tones
The 702T can generate an audible beep, or warning “bell”, in the headphones when an error has oc-
curred. The specific error will be reported on the LCD. The output level of the warning bell is menu-
selectable from off to –12 dBFS in the Setup Menu.
Recording Start and Stop Bells
If the Setup Menu option HP: RECORD/STOP BELL is enabled, the 702T will generate beeps to alert
the user of the recorder’s current status. These beeps are only sent to the headphone monitor, these
beeps are not present in the recordings or at the analog outputs.
7-Series Status HP: Bell
Recording One 440 Hz beep
Paused (if using Rec: Record Pause) One 220 Hz beep
Stopped

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.
Metering and Display
The 702T features a 38-segment LED (2 x 19) signal level meter. The DSP-controlled meter provides
a selection of ballistics and lighting intensities. In addition, peak indicators on input channels show
overload activity.
Output Meter
0 dBFS track LEDs are programmable
as peak LEDs
(0 dBFS to -20 dBFS)
The meter uses energy efficient LEDs viewable in full sunlight. The 702T output meter is unaffected
by shock or extremes in temperature and humidity. Meter ballistics are Setup Menu selectable among
VU, Peak, Peak-Hold, VU + Peak and VU + PeakHold.
The meter uses a compound metering scale which increases meter resolution in the most important
part of the scale. From - 50 to - 40 dBFS, each LED segment equals approximately 10 dB. From - 40 to
- 12 dBFS, each segment equals 2 dB. From - 12 to 0 dBFS each segment equals 4 dB.
