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 ohms. 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
Source and level behave like a DR3 remote, but with any combination of Levels, Toggles, Selections or Commands.
On the back, there are two 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 sum 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 devices.
A built-in 4-watt stereo amplifier powers a small stereo pair of room speakers, or software can switch this amp 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.
The RAD26 fits with most decor in a matte white metal box. A programmable ambient light sensor automatically dims the display and status LEDs in darkened rooms.
