EXP3x Zone Output Expander
Description
The EXP3x is an 8-channel analog output & DSP expander for
the HAL1x, which is required for operation. It also sports 8 logic
outputs, 6 DR remote ports and 2 RAD ports making a 4-input,
12-output audio device — depending on which two RADs are
connected. Thus, 32 daisy-chained EXP3x Expanders provide 256
discrete zone outputs maximum, including output compression,
parametric EQ, two levels of paging and background music.
These 32 EXP3x Expanders would also provide 64 RAD ports,
192 DR ports and 256 logic outputs.
The dedicated DSP for each of the 8 analog outputs offers two
signal processing choices independently selectable, per output.
When you need background music, paging and emergency pag-
ing on an output, select the Zone Output processing set. This
provides a Zone Processor block, an Emergency Zone in addition
to a Compressor and a 5-band parametric EQ with high- and
low-cut filters. When Line Output is selected, the compressor and
parametric EQ are available without the zone processing block
and emergency paging blocks.

EXP3x Application Example
Each EXP3x provides full support for an 8-zone cluster without
consuming HAL1x DSP, DR or RAD resources. All of the DSP
required for paging, distributed background music selection,
PEQ, dynamics and Level control is included in the device. DR
and RAD resource also scale with the device with provision for 6
DR ports and 2 RAD ports.
For example, a single DR3 remote in a manager’s office or rack
room can provide independent level for all 8 outputs from the
EXP3x. Selection and level within 5 different zones is available us-
ing 5 DR3 remotes. The first RAD port allows local zone sources
such as a page or podium mic, plus a laptop feed when using a
RAD2. Or, as shown on the facing page, a Rane PAGER1 Paging
Station( ) instead supplies paging throughout many zones. Per-
haps the weekend DJ or band needs to plug a mixer into the wall
and automatically or manually override the background music
with a DR remote. A RAD3 in the second EXP3x’s RAD port
( ) provides balanced XLR line-level inputs to the system for the
DJ or band mixer.
The logic outputs on the EXP3x are suited for legacy paging
systems where relays within each zone’s 70/100 volt volume
controls must be tripped during a page. Simply link the Logic
Out to a Page Active in the Paging Manager, and use a Logic Out
to drive a relay. This turns up the remote’s volume during pages.
With 8 logic outputs, 8 zones of old-school constant voltage
paging are supported.
Pushing the EXP3x Zone Output Expander
If your application requires eight floors of combined retail and
office space, where each floor contains 8 zones, the EXP3x is
clearly a winning solution with one HAL1x. This would support
64 zones, a handful of building-wide global background music
channels connected to the HAL1x directly, paging via Pager1s
within individual or even across a few floors, plus a couple local-
only audio sources per floor. Add up to 58 DR remotes, one or
two RADs per floor and you’re done. You can even spread the
EXP3x devices across different equipment rooms using dedicated,
CAT 5e or better cable runs as long as they don’t exceed 100
meters (300 feet). Use standard Ethernet Gigabit Media
Converters within the daisy-chained Expansion Bus to achieve
distances up to 12 kilometers, or 7.5 miles.
In existing room combine facilities, the EXP3x slots ahead of
the amplifiers to upgrade existing facilities.
