iLive xDR-16 Getting Started Guide 5 AP8331 iss.2
The xDR-16
Mic/Line inputs High performance, recallable
analogue preamps for balanced or unbalanced
microphone and line level signals. Gain, Pad
and 48V are digitally controlled within the
preamp. Digital Trim and Polarity are available
within the DSP channel.
Inputs are identified by Slot (card position) and
Socket (number), for example A1 or B8. Any
input can be patched to any DSP channel
using the
PREAMP screen.
Line outputs Line level, balanced XLR
outputs. Nominal level +4dBu with +22dBu
maximum providing +18dB headroom.
iLive signals can be patched to any output
socket using the
OUTPUTS screen. The
outputs are relay protected to prevent power
on or off thumps.
Rack Ears Fit
into a 19” rack
or flightcase.
Network A built-in 2 port network switch for plugging
in a laptop or wifi router / access point located near
the expander. Can also be used to bridge third party
non-iLive network data over ACE to the network ports
on the master MixRack. All devices on the iLive
network must have compatible IP addresses. A
recessed switch lets you reset the xDR IP address to
factory default of 192.168.1.20.
ACE™ Port A Connect a single CAT5 cable up to
120m (400’) (depending on cable type) to link audio
and control between the xDR and the MixRack. You
do not need a separate Network cable because
control is bridged over ACE. The xDR plugs into one
of the two Link ports on the ACE option card fitted to
Port B in the master MixRack.
SYSTEM LOCK
indicates expander
digital audio is
sync locked to the
MixRack.
Port B audio network option
slot. If required, fit one of the
option cards available for system
expansion, recording and
distributed audio networking.
Capable of up to 64 outputs and
48 inputs, 48kHz sampling rate.
Port B gets its signals from the
MixRack via the xDR Port A ACE
link and therefore shares audio
with the XLR inputs and outputs.
Refer to the Routing Map later in
this guide for details on which
signals are available.
Backup power supply input The
xDR has a mains power supply
built in. This socket lets you add
the external iPS10 rack mount
power supply as a redundant
backup.
Mains power input Use the IEC
mains power cord provided with
the xDR. The cord can be held in
place using the plastic clip. Press
the switch to power the unit on or
off. Read the Safety Sheet
provided with the unit before using
the xDR-16.
Fan Do not obstruct
the fan or the ventilation
slots on the side of the
unit.
AES digital out option Shown
fitted in the last card position.
Each socket handles two signals,
in this case 5-6 and 7-8.
