Module options - System
iDR-64 RackExtra DSP
This is the DSP mix engine, the ‘brains’ of the iLive system.
The DSP (Digital Signal Processing) handles the audio signal
processing such as EQ, dynamics, delays and mixing. The
‘RackExtra’ version includes additional DSP to handle up to
8 internal stereo effects ‘racks’.
Note: The DSP is in the MixRack not the Surface. Audio
in the Surface is converted to digital and transported via
audio network Port A to the MixRack where it is processed
by the iDR-64 RackExtra module. The surface cannot be
used as a stand alone mixer without the iDR10, iDR0, iDR-
32 or iDR-48 MixRack which houses this module.
REMOTE AUDIO (RAB) part M-RAB-B, C or D
Handles the audio clock, headphones signal and interface
for up to two digital audio networks.
HEADPHONES A built-in headphones amplifier with
volume control and ¼” output socket lets you listen to the
signal currently selected using the PAFL function. This is the
same signal presented to the Surface headphones / local
monitor system.
SYSTEM LOCK The yellow LED lights to indicate digital
audio sync lock. If it is not lit check that the correct system
Audio Clock Source is selected.
Setting audio clock source (Surface TouchScreen
MIXRACK / Mixer Pref / Audio Sync ) If the MixRack is part
of a single rack system, or the master in a linked
FOH/Monitor system then set the Clock Source to ‘Internal’.
If it is the slave getting its channel preamp sources via the
Port B network then set it to MixRack Remote B. If it is being
synchronized to an external DARS source then set it to
‘DARS’.
Port A (ESA) and Port B (ESB) audio network options -
Currently only EtherSound is available as an internal option.
The iDR10 may be ordered with none, one or both
EtherSound option cards fitted:
Part M-RAB-B 1x ES (ESA)
Part M-RAB-C no ES
Part M-RAB-D 2x ES (ESA and ESB)
Use Port A to transport audio to and from the iLive Surface
and/or other EtherSound equipped devices such as break
out / break in boxes and speaker controllers. Use ESB to
transport audio between iDR racks and other EtherSound
equipped devices such as the Digigram LX6464 PCI
multitrack recording card.
Note: With no ES option fitted you can still connect the
PAFL monitor and talkback signals to the iLive Surface using
analogue connections.
