Introduction
Using one shielded category cable drop
, the RAD26 provides any room with a dual 4-watt amp, end
user control via a color custom LCD & encoders, a dual universal audio I/O interface, plus headphone
output and line-level input jacks for local needs. Three logic closure inputs and three active-low outputs
add to the control capabilities. The amplifier permits a single channel option at 8 watts into 8
Ω
.
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
•
Amplifier outputs for ceiling speakers
•
Level control
•
Source selection
Each RAD26 may be installed onto a standard U.S. 2-gang electrical box, 1-gang electrical box, or
flush-mounted to a wall surface. The exterior finish is matte white.
Source and level behave like a Rane 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. The Line-Plus inputs accept unbalanced left and right signals and sums them to
mono. 24 V phantom power is available for condenser mics. For end users, there is a 3.5 mm (1/8")
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 amplifier 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
amplifier 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.
