FULL PRODUCT DESCRIPTION

TW1010 volume control

Communication Technology central Tri-wire controller with override, music/speech, music only, speech oonly use with TVC-25.

TVC-25 and TW1010 volume controls

TW1010 is an interface between the amplifier and loudspeaker/s to allow low cost overall paging override, volume restoration,where a number of individual loudspeaker line volume controls are to be installed.

Without TRIWIRE, each volume control would need to be fitted with an override relay requiring centrally sourced powering, involving 4 wire cabling. As the name suggests, the TRIWIRE system uses only three wires linked to the volume controls, enabling a lower cost of installation.

A special TRIWIRE line volume control, TVC25, is recommended for use with this system, though any of the CommunicationTechnology range is compatible.

TW1010 has the advantage of being low profile and suitable for all back boxes of at least 20mm depth, supplied standard with an Ivory White plastic front panel. For installation in close proximity to the host amplifier.
