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 more recent
‘RackExtra’ version includes additional DSP to
handle up to 8 internal stereo effects ‘racks’. Older
systems with 2 effects may be upgraded to this
version by swapping out the iDR-64 DSP module.
Note: The DSP is in the MixRack not the Surface.
Audio in the Surface is converted to digital and
transported via EtherSound 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 or iDR0 rack 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 iDR10 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 EtherSound network ESB then set it to
‘ESB’. If it is being synchronized to an external
DARS source then set it to ‘DARS’.
ESA and ESB audio network options - 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 ESA 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.
