Miscellaneous
Ext Sync illuminates to indicate that sync source is set to an external reference in the Setup menu. The
LED blinks if there is no valid sync signal presented at the connector.
The Dithered LED illuminates during record when 24-bit digital audio is being dithered down to a 16-
bit word size. It is also turned on during playback of a 24-bit cut when the output word size is set to
16-Bits. Dithering settings can be changed in the Setup menus.
SRC illuminates to indicate that the Sample Rate Converter has been switched into the data path
between the recorded file and connectors. SRC may illuminate during either record or playback. SRC
settings can be changed in the Setup menus.
When the machine is idle with Input Monitors on, or in Record Ready, or while recording; the front panel
indicators show the state of the signal to be recorded.
When the machine is idle with Input Monitors off, or while playing a cut; the front panel indicators show
the state of the currently selected cut.
The EXT SYNC indicator shows the state of the receiver when D-Net Receiver is on, or a D-Net Receive is
in progress. All other front panel indicators are turned off. EXT SYNC is off when there is no signal at the
receiver. The indication is on when there is a valid signal at the receiver, and the indication blinks when
there is a non-conforming signal at the receiver.
All front panel indicators are off while a D-Net send is in progress.
Peak Level Meters
DigiCart/E uses quasi-peak reading LED level meters for monitoring left and right channel audio levels.
These meters have been selected over standard VU meters for their advantages in monitoring digital audio.
When a +4dBu reference signal is applied to an analog input, the amplitude of the resulting digital signal
will be 16dB below digital full scale. Unity gain is always maintained from analog input to analog output,
unless the cut’s output gain has been adjusted.
The meters on DigiCart/E have a Clip level indication. The Clip LED will turn on during record whenever
the signal exceeds digital full scale. If a clipped file is played, the Clip LED will only turn ON during the
period when the signal exceeds digital full scale.
Headphone Jack
DigiCart/E has a ¼” stereo headphone jack on the front panel for convenient monitoring. The master
volume control for this jack is set via a menu item in Setup|Set Headphone Level. The level can be adjusted
from 0-64 (1dB per step), and is saved in non-volatile memory.
Selection Knob
The front panel selection knob can be rotated to:
• Select audio files (Cuts) for playback or editing
• Scroll and select items in a list
• Select from different values in a menu
