A range of 50/70/100V line remote volume controls for loads of 25, 100 and 300 watts with provision for local volume restoration for paging announcements by inbuilt 24v relay override.

Each control has been designed to provide excellent frequency response with minimum quiescent power loss, using uniquely wound auto-transformers for maximum efficiency.

Key Features: 

A rugged, stepped, user control.
Collet fixing knobs.
Permanent, push-on, wiring connectors conveniently at one end of the p.c. board, so wiring is easy and ‘installation stable’.
Easily adjustable, colour coded, on-board header receptacles for option selection; 300 watt excluded, uses terminal selection.
Detailed, diagrammatic instructions make preparation and installation easy.

Pre-set Attenuation

LVC300 excepted, when operating with remote relay override, paging levels can be pre-set attenuated so that, in noisy warehouses or a quiet office, paging volumes can be optimised to the prevailing ambient noise conditions.

Versions are available to special order with a paging on/off switch, for example, for discussion or conference areas, so that meetings need not be disturbed by unwanted paging announcements.

Also suitable, by ‘on-board’ option selection, for three wire amplifier sourced paging override systems, TRIWIRE.

Large Range of Panels

As standard LVC025 and LVC100 volume controls are fitted to ivory plastics UK switchplates, moulded from ABS material to make them virtually unbreakable. Subject to a small minimum quantity, front panels can be hot foil stamped with the ultimate supplier or installer, even the installed venue name. Various metal front panel options are available at extra cost.
