W5-2 Wall mount MultiLoop hearing loop driver

Part code: W5-2 Wall mount MultiLoop hearing loop driver

The W5-2 is designed particularly for small rooms where there is no AV rack and no network monitoring requirements, but can still make use of Ampetronic’s industry leading spill control design.

W5-2 Wall mount MultiLoop hearing loop driver

The W5-2 is designed particularly for small rooms where there is no AV rack and no network monitoring requirements, but can still make use of Ampetronic’s industry leading spill control design.

Design templates for low spill in especially small rooms are available to download from the Loopworks portal here. These are optimised specifically for the W5-2, including two turn options with twin core flat copper tape for higher loss environments.

Note that a Loopworks account is needed to access design template downloads, it is free to register and grants access to the full suite of Loopworks tools and resources.

Use the calculator below to find the most suitable design template for your room and determine the required cable length.

A suitable design will be automatically chosen based on the room length. Follow the links below to download installation drawings for the chosen design.

Gap to wall distance must balance between coverage and overspill control. In larger rooms a distance of 0.5m is generally recommended.

Where rooms are narrow or furniture is close to the walls a smaller gap may be required to cover all listening positions, however this will lead to increased overspill in that direction.

Top and bottom gaps are automatically worked out to centre the chosen design within the room length.

Array B Cable:

Up to 5m of 2.5mm² twisted feed cable can be used between the amplifier and loop tapes.
