Description
The EXP5x is a 12 Mic/Line/Line-Plus input & DSP expander
for the HAL1x, which is required for operation. It also supplies
four DR ports useful for adding source selection and/or volume
control remotes such as the DR3. Each of the 12 inputs
independently supports either dynamic mic, phantom mic, +4
dBu line-level, or Rane’s new Line-Plus input. Line-Plus accepts

SHIELDED CAT 5e - 24 VDC @ 50 mA
-10 dBV unbalanced Left/Right Monoed together on the +
and - ports, respectively. For stereo unbalanced sources, Line-
Plus allows connecting the stereo RCA left tip conductor to the
+ terminal, the RCA right tip to the - terminal, and both RCA
shields to the shield on the EXP5x Euroblock. Select Line-Plus
and you get a properly monoed audio channel.
EXP5x Application Example
The EXP5x is perfectly suited to expand a HAL1x’s analog audio
inputs. Control is also expanded given its 4 DR ports. Each of the
12 inputs can independently accept mic, line, or Line-Plus audio
— the ultimate in flexible input topologies. Also worth noting
is the performance enhancement achieved since the mic input
topologies automatically compensate for the sensitivity difference
between condenser and dynamic mics.
In a meeting room with ten microphones (see facing page), one
audio source (e.g., blu-ray) and a laptop on the podium, all these
channels can connect directly to one EXP5x. A single DR3 in the
room can select the audio source (blu-ray or laptop) and adjust
the room volume. Or, the DR3 can be programmed as a mixer
allowing independent level adjustment of all 12 sources in the
room: 10 mics, blu-ray and laptop. If the podium location moves
from the north to the east wall, duplicate remotes can provide
multiple control locations. Use a preset recalled from a switch clo-
sure, DR2 remote or 3rd-party Ethernet control system to “spin”
the room or disable any DR remote in a room.
There are equipment placement options. If the HAL1x lives
in the equipment room, the EXP5x can live in the podium along
with the blu-ray, and a single CAT 5 returns to the HAL1x. How-
ever, if you are upgrading an existing facility, the EXP5x connects
at the end of the existing analog conduit feeds in one or more
equipment rooms.
If you had 12 such meeting rooms, use 12 daisy-chained
EXP5x Expanders and a single HAL1x. The figure on the next
page shows only four such rooms. There would be plenty of spare
DR ports available for adding control locations. The four RAD
ports on the HAL1x support the addition of page sources (e.g.,
PAGER1) or portable 8-channel AM2 Automixers. AM mixers
can be added to larger rooms - even during a meeting - to add 8
more gain-shared mixed mics to the 10 in any given room. Re-
view the cascading feature of the Gain-sharing Auto Mixer or the
Room Combine Processing blocks within Halogen for details.
