RAD26 - Audio Amplifier Rane - Free user manual and instructions

USER MANUAL RAD26 Rane

User Guide (English)

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.

Example

This configuration works for presentations in both boardrooms and classrooms.

The mic connects to the rear of the RAD26. It can be from a ceiling mic, or from a handheld or lavalier wireless mic, with 24 V 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 (1/8") 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.

The amplifier is set to dual 4-watt mode to drive the left and right speakers.

The logic outputs can be configured as toggle controls to move the motorized screen up and down, and turn the projector on and off.

HAL lets you page into this room, ducking the local audio, or overriding it—automatically.

1. RAD Status Indicators: These LEDs show the state of operation for the RAD Port:

• TX LED: Lights green when audio is successfully transmitted.
- RX LED: Lights green when audio is successfully received.
- Comm LED: Lights green when communication is established with another device.
- Power LED: Lights green when the RAD Port is receiving 24-volt power. This also indicates that the twisted pair for power within the cable is wired and crimped properly.

Rear Panel

1. RAD Port (RJ-45): This port uses a Shielded CAT 5e cable to connect to any HAL RAD Port. The CAT 5 distance from a HAL RAD Port to the RAD26 must not be more than 100 m (325 ft). RPI (sold separately) can go anywhere in between to supply display and amplifier power. RPI is required when using HAL models.
2. Inputs: Two balanced, switchable Mic / Line / Line-Plus audio inputs are available. The Line-Plus inputs accept unbalanced left and right signals and sums them to mono. 24 V phantom power is available for condenser mics. Three Logic inputs allow for additional controls such as push to talk, push to mute, etc.
3. Amplifier Outputs: Two 8Ω loudspeaker outputs can power stereo 4-watt speakers, or a single 8-watt speaker.
4. Outputs: Two balanced line outputs are available for driving an external amplifier or powered subwoofer for more output. Three Logic outputs allow for control of another device, light, projector, hot tub, etc.

RPI (Remote Power Injector) (sold separately)

The 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 amplifiers. The RPI is inserted anywhere between the HAL and the RAD26, which can be up to 100 meters (325 feet) apart.
