Using one shielded category cable drop, the R AD26 provides
any room with a dual 4-watt amp, end user control via a color
custom LCD display & encoders, a dual universal audio I/O
interface, plus headphone output and line-level input jacks for
local needs. ree logic closure inputs and three active-low
outputs add to the control capabilities. e amplier permits a
single channel option at 8 watts into 8. Applications include:
• Presentation source and volume, projector and screen control.
• Meeting room with A/V teleconferencing and speakers.
• Spa with BGM, local music input and stereo ceiling speakers.
• Hotel or cruise ship room TV and local input sound system.
A RAD26 provides enough I/O and control to support one
room in a HAL audio system which may require these features:
• Local audio line input (smartphone, laptop, MP3, DVD)
• One or two microphone or line-level inputs
• Amplier outputs for ceiling speakers
• Level control
• Source selection.

ONE ROOM RAD REMOTE
Each RAD26 may be installed onto a standard US 2-gang
electrical box, 1-gang electrical box, or ush-mounted to a wall
surface. e exterior nish is matte white.
Source and level behave like a DR3 remote, but with any
combination of Levels, Toggles, Selections or Commands.
On the back there are 2 balanced Euroblock Mic / Line /
Line-Plus audio inputs with the mode set in Halogen software.
e Line-Plus inputs accept unbalanced left and right signals
and sums them to mono. 24V phantom power is available for
condenser mics. For end users, there is a 3.5 mm Aux input on
the underside of the front, accepting the output of a smartphone,
laptop or other consumer device.
A built-in 4-watt stereo amplier powers a small stereo pair
of room speakers, or this amp can be switched in software to
power a single 8-watt speaker. Balanced line outputs can drive an
external amplier or powered subwoofer for more output.
Software logic senses an inserted connector at the Aux In or
Headphone jacks to optionally override the rear connections.

It can be from a ceiling mic, or from a handheld or lavalier wireless mic, with 24V phantom
power available for condenser mics.
A presenter can easily plug a laptop, tablet
or smartphone into the sound system. A regular
consumer cable with stereo 3.5 mm line plugs
will work.
When no plug is present, background music
or noise masking is available, sent from a HAL
multiprocessor elsewhere in the building. A
RAD26 selection decides which source, and how
loud.
e amplier is set to dual 4 watt mode to
drive the left and right speakers.

RAD26 Hotel or Cruise Ship Guest Room Application
is conguration works for private guest rooms
in hotels, resorts, and cruise ships.
e television line output connects to the rear
of the RAD26, delivering better sound than the
TV speakers. In-house video can deliver shows
to guests, virtually expanding theater capacity to
the entire ship or resort.
A guest can easily plug a laptop, tablet or
smartphone into the sound system, using a regular consumer stereo 3.5 mm line plug cable.
On cruise ships, important messages from
the captain must be heard in the room speakers.
e volume control can be set for minimum and
maximum levels so that important pages aren't
missed, yet the guest is given volume control.
e amp is in dual 4 W mode to drive the
two ceiling speakers. Depending on source material and speaker locations, stereo TV audio can
wire to the two line inputs, or as Line-Plus left
and right sum to mono. If the TV is mono'ed,
the other input could be a local talkback mic.
When a guest's headphones are plugged in,
the room speaker ampliers can be optionally
muted for the spouse to get some sleep.

ONE ROOM RAD REMOTE
RAD26 Rear Panel (attaches to wall mount bracket)RAD26 Rear Wall Mount Bracket (included)
Includes RPI (Remote Power Injector)
e included midspan power injector (not PoE) connects shielded CAT 5e (or better) cables between any HAL and the RAD26
to deliver communications and the extra power needed for the
display and ampliers. e RPI is inserted anywhere between the
HAL and the RAD26, which can be up to 100 meters (325 feet)
apart. An IEC power cable is included.
RAD26 Applications
Hotels with small meeting rooms and spa rooms require local
inputs and control, but must also receive paging or music
from elsewhere in the building. Many oces and campuses
provide meeting and conference rooms for small groups with
in-room A/V presentations, but must also receive emergency
announcements. Other RADs and DRs can provide these
functions, but require more than one shielded CAT 5 cable. e
RAD26 provides all the features required in a single RAD.
Optional RB2 Rack Mount Accessory
e RAD26 and a round 4 speaker can mount in a 19 rack
with this 3U black-painted metal panel. e RB2 was designed
with the EIA 4 loudspeaker “standard” in mind, with a mounting bolt circle diameter of 120 mm, or 4.7 ±0.05.
General RAD Description
e entire family of RAD models interface with HAL for digital
conversion at the wall. Each converts analog audio to and/or
from 24-bit, 48 kHz digital audio. Shielded CAT 5e (or better)
cable and termination transport four digital audio channels –
two channels each direction – as well as power, ground and a
communications channel, with status indicators at each RAD,
HAL, or EXP unit, and in Halogen software. e host HAL
auto-checks the CAT 5 crimp and veries audio. All RADs are
both “location-aware” and hot-swappable. Light sensors dim the
RAD indicators in dark rooms.
