The digital transmission processor d07 has a digital signal output. For the
problem-free combination of following digital devices, the digital signal
processing can be locked to an external clock reference. The selection of the
corresponding sync source is made in the SYNC MODE menu during setup. If
the chosen sync input is connected with the sync signal, this signal is used for
synchronization automatically. All sync sources can be used for locking A/D-
converters at the analogue inputs as well. The digital output signal can be
clocked with the following clock frequencies:
INTERNAL locks both the A/D-converters and the digital output with
the internal reference 44,1 or 48 kHz. Digital inputs are
connected via sample rate converter
AES INPUT locks with the clock frequency of the input signal at
digital input CH 1/2 (AES/EBU, 44,1...48 kHz)
EXT AES locks with the AES signal at the sync input
(AES, 44,1...48 kHz) Digital inputs are connected via sample
rate converter
EXT WCLK locks with the word clock signal at the sync input
(WCLK, 44,1...48 kHz) Digital inputs are connected via sample
rate converter
optional:
EXT VIDEO locks with black burst at sync input (internal 48 kHz) Digital
inputs are connected via sample rate converter
The analog audio inputs are RFI filtered and analogue outputs are balanced
and floating like transformer coupled devices. All the audio connectors are via
rear panel mounted connectors. Standard XLR connectors are used. These
are always wired to the AES standard:
pin 1 X
pin 2 L
pin 3 R
Balanced connections are preferred whenever the other equipment provides
balanced inputs/outputs. All line level connections should be wired with twin
screened cable for low noise and reliability. The screens of the cable should
be connected at one end only. Input cable screening therefore needs to be
derived from the signal source end as pin 1 is ground lifted at low frequencies
for the inputs.
If the equipment driving the digital audio level processor d07 has unbalanced
outputs then you will need to add a wire jumper such that the screen
connection of Pin 1 of the XLR is shorted to Pin 3.
If the equipment being connected to the d07 have only unbalanced inputs,
then we recommend still to use a balanced (ie. 2 core shielded cable) cable
where Pin 1 and Pin 3 are connected in the cable ends away from the digital
audio level processor d07.
