Adding the iDR-in and iDR-out Audio Expanders
iDR-in and iDR-out are add-on audio expander units for the iDR-4 and iDR-8 audio mix processors. They provide
additional analogue audio inputs and outputs to add to those on the main unit. The iDR-in has 8 mic/line inputs, the
iDR-out has 8 line outputs. Only one of each may be added to the iDR system bringing it up to a maximum 14x14
audio matrix. These units do not have any processing built in. They simply convert between analogue and digital
audio to work with an 8 channel wide digital bus which feeds the main unit via a CAT5 STP cable. The DSP power is
available on the main unit which features the full 16x16 processing matrix. Both units have 8 front panel LEDs in
addition to the 3 status indicators. These are 3-colour soft LEDs which can be assigned as audio meters, mute
indicators or static patch related indicators. They are programmed in the usual way using the iDR System Manager
software. The iDR-in features input preamps complete with switchable 48V phantom power, 20dB pad, gain control
and pre-converter soft limiter. Control of the expanders is via the DR-Link port using a CAT5 STP cable. This means
that two CAT5 cables are required to interconnect an expander to the main unit. Maximum distance between the units
is 250 metres. Local mains power is required.
Make sure you have read the Important Safety
Instructions printed earlier. Also check that your local
mains supply is compatible with that printed on the rear
panel of the unit. Ensure that the correct mains lead with
moulded plug and IEC connector has been supplied. For
your own safety and optimum performance make sure the
system is correctly grounded.
To avoid any unexpected audible clicks or thumps
always turn connected power amplifiers down or off before
switching the iDR or any other signal equipment on or off.
Check the connections
The iDR-in AUDIO OUT
connects to the iDR-4 AUDIO IN. The iDR-out AUDIO IN
connects to the iDR-4 AUDIO OUT. Ensure that the expander
DR-Link IN connects to DR-Link on the iDR-4 it is associated
with. If both expanders connect to the same iDR-4 then daisy
chain from DR-Link OUT on one to DR-Link IN on the other.
Turning the expander on or off
Turn the unit on
by pressing the rear panel power ON/OFF switch. The power
LED lights up. The link LED lights if the DR-Link connection is
established with the iDR-4. Then the lock LED lights once
audio communication is established with the iDR-4. The iDR
System Manager detects the presence of the expander.
Checking for expanders
You can use the front
panel iDR-4 Setup menus to check if any expanders are
connected and working. This is useful when the expanders are
located far away from the main unit. With the face plate
removed access menu *8 Diagnostics and scroll to Audio Exp.
