DRGrounding

Careful grounding of DRs is important for optimum performance. Except for the DR4, all RADs and DRs are pow-

ered from the +24 VDC & Ground twisted pair located within the shielded CAT 5e (or better) cable connecting

them to the HAL system of multiprocessors. The exposed metal of all RADs and DRs is connected to the ground

conductor inside the cable and to the cable shield when properly terminated. The shield conductor and the ground

twist are in parallel and are connected together at both cable ends. This in turn connects the HAL/audio equipment

rack grounding point and the metal (if used) junction box mounting the RADs and DRs.

NOTE: For some electrical systems (e.g., isolated grounding systems - sometimes called a single point or star

ground) the grounding procedure outlined above may short two fingers of the building ground system. If this

creates a problem, then use of non-conductive junction boxes, or insulating mounting methods are rec-

ommended (or very much required!).

Available Digital Remote Models

Following are the types of DRs currently available for your HAL System. The DR models available will vary over

time as Rane's engineers ponder and design new and better ways to remotely control an audio system. For the most

current list of DRs, see the Rane website.

NOTE: Several of the DRs mount inside a US one-gang or two-gang switchbox (DR1, DR2, DR3, and DR5).

See the Rane website for a detailed listing of acceptable models of switchboxes. Note that the Decora plates

are also included with the DR1, DR2, and DR3.

NOTE FOR DRAG NET USERS: Remember the SR3 remote for Drag Net systems and how it was too wide to

allow the mounting of two or more of them beside each other in a standard switch box? You will be happy

to know that the HAL System DRs can be mounted directly beside each other in any combination, allowing

you to use several DRs in the same two, three, or four-gang switchbox.

NOTE: DR1, DR2, and DR3 display screens are dynamic, automatically updating when the available options

change through preset activation, room combining, and so on. Therefore, the user always sees the options

that are currently available.

DR1

A DR1 provides a single level control. A DR1 is used most commonly to control volume.
