Volume Controller / Patch Panel
When there is a need to control the volume of speakers, a volume controller shall be required, either at localized area or from the rack. Often a group of speakers at a localized area such as meeting room or function room shall need volume controller and also local music source, independently from the main feed, but would require a bypass in case of emergency broadcast. Amperes has all the parts to achieve this ..
Various ratings of speaker volume controllers are available to choose from and speaker patch is available for patching local source to a localised speakers while allowing central paging overriding signal. They had been serving well for the past decade.
​
PR7400 allows central paging to override a local source, without the availability of 24V DC overriding signal. Please click to read further of what it can offer.

VC8000 has slimmer front face plate, with grip slip knob, preventing overturn of the switch. It is available in ratings from 10W 8 Ohm, 10W 100V line to 100W 100V.
​
It is suitable for 4 wire system installation and comes in standard white colour. Other colour can be requested.
VR7615
VR7600 Series
Rack Mount Zone Volume Controllers
The rack mounted versions are meant for installation at central rack. allowing zone by zone volume attenuation.
​
Standard versions are 6 x 50, 6 x 100 and 6 z 150W per channel. If combinations of wattage is required, it can be customised upon ordering.
AV7200
Auto Volume Controllers
AV7200 is auto volume controller for localised areas. It varies the speaker volume at 100V line level instead of sending back control data to rack for volume adjustment. As such, it can be applied to existing installations, controlling speaker load of up to 100W.
​
Among suitable installation areas are shopping malls, transportation stations, public building lobbies, etc.
Speaker Patch Panel
VP7501
Local Speaker Patch Panel
To utilise the speakers in a localised area such as meeting room, retail unit or restaurants, a patch panel shall be required to allow local amplifier to power up the speakers.
​
This however would still allow emergency broadcast to override the local music / paging source when required.
​
VP7501 is 50W in rating comes with standard 86 x 86 mm face plate. American version of 70 x 120 mm is available upon request.
VP7810
Speaker Overriding Unit
It is normally used in hotel rooms, which allows central paging 100V line audio to override music from TV to a 8 Ohm speaker in bathroom or foyer. In another word, it converts 100V audio line downwards to drive 8 Ohm speaker.
​
It comes with overriding relay and LED indicator to show the presence of 24V DC overriding voltage.
Remote Paging Override Module
PR7400
Remote Paging Override Module
PR7400 is a new addition to VC / VP category, which is a module for providing a relay contact whenever a paging is in progress, as well as converting the 100V line paging audio to line level, all in a box.
​
The available functions of the unit shall be :
​
Relay :
NO and NC relay of 1A contact allows local BGM source overriding, bypass local volume controller to allow central paging to pass through. This is useful during essential paging and whenever 24V DC overriding signal is not available in the cabling works.
​
100V - Line audio converter
When it is required that the central paging to be broadcasted to local speakers utilising the local amplifier / system, it provides an audio conversion with balanced line audio.
