Sampling Frequency
To record via the digital inputs, the DR16pro must be set to the same sampling frequency as that
used by the incoming digital signal. This is because the DR16pro has to synchronize with the
incoming signal (word sync). If you are recording from a CD, prerecorded MD, this will be 44.1kHz.
If you are recording from a DAT that was recorded via analog inputs, this will be 48kHz.
If you attempt to connect a digital input from a source with a sampling frequency different than the
current setting of the DR16pro, the message “BAD INPUT” will be displayed when you press a
TRACK REC key. See “Selecting the Sampling Frequency” on page 31.
Digital Audio Interfaces
The DR16pro includes a built in stereo (2-channel) AES/EBU interface that can be used as a
record source for any track. Additionally, a multi-channel digital audio option card can be fitted
providing up to an additional 8-inputs and 16-outputs in either AES/EBU or ADAT format.
Digital Audio Formats
There are two industry-standard digital audio formats. Type 1 is usually referred to as AES/EBU
format. Type 2 is also known as S/PDIF format. Both the built in stereo digital audio interface on
the rear panel of the DR16pro (XLR and RCA/phono) can receive either Type 1 or Type 2 signals
as input.
To switch to digital inputs:
1) Press the DIGI key.
The LED over the DIGI key lights. Input channels 1 and 2 are switched to digital. No analog
signals at channels 1 and 2 will be input.
If no digital signal is input at the currently active connector, the LED flashes and the message
“PLL UNLOCK” will flash on the display.
To select the active digital connector:
1) Press the SUB-MENU key.
The indicator in the key will flash and the text “SUB-MENU” will appear on the display.
2) Press the DIGI(D IN) key.
The display will show the currently active connector.
3) Use the JOG/SHUTTLE control to select the digital connector.
4) Press the STORE/ENT key.
The new connector will be selected.
