3. INSTALLATION
The ACCENT2 audio inputs are RFI filtered and
with the outputs electronically balanced and
floating. All the audio connectors are via rear
panel mounted connectors. Standard XLR
connectors are used. These are allways wired
to the AES standard:
pin 1 X Screen screen
pin 2 L Live audio 0°
pin 3 R Return audio 180°.
AUDIO CONNECTIONS 3.7
Balanced connections are to be 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 ACCENT2 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 mpx01
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
ACCENT2.
REMOTE CONTROL 3.8
GPI IN / TALLY OUT 3.8.1
The Digital Dynamics Processor ACCENT2
can be remote-controlled by means of parallel
GPI contacts. Even it can signal specific
device statuses via parallel Tally lines.
use : remote-controlled changeover of
presets or other events
