Silent PA. Silent Conference System Equipment Australia

Private public address systems equipment for exhibitions and conferences when personal, direct, discreet and quiet communication is required.

Silent PA silent conference systems enables direct communication with your delegates wherever they are without PA speakers blaring away and interrupting others at a conference or exhibition and in any language.At the trade show below the client wanted their customers to be able to walk between exhibits in their own time and listen to talks from various speakers within each area regardless of sound from various pieces of machinery and other speakers. They had ten channels to choose from and did not require instruction.

Silent PA at a trade exhibition: Can you see our IR radiators?

When multi-theatre exhibitions are used delegates can move from area to area and simply change their IR (infra-red) or RF (radio-frequency) receiver channels to suit the area they are in. It’s very simple and we have unique 3cm large back-lit displays on our receivers that allow easy selection of channel, stand or room numbers that even visually impaired delegates can use with ease.

Silent Conference Headphones

Which are best - most suitable
Personal Hearing Aide induction loop:
There is also no need for hearing disability Induction loop drivers to be installed in the area as hearing impaired delegates can simply swap their earphones for a personal neck worn induction loop provided by us.This personal induction loop is for use with hearing aides -remove our earphone and plug in this induction loop in its place. Delegates will know how to activate their own hearing system to make use of the 'loop'.
Double over the head head-phone:
Usually best used where there is a noisy environment.
Single ear-phone:
No foam - slips over the ear lobe - not in the ear. Hygienic. Discreet - most people don't even know you are wearing one. Also makes it easier to hear the 'feeling' of the room and not to shout at delegates next to you when speaking to them.

What is required for silent PA?

IR or RF Silent PA speech receivers?

We use either IR (infra-red) or RF (radio frequency) speech receivers.

Both have their advantages - both technically and cost wise. Both cannot be eavesdropped as with IR you must be in the same room to hear the IR and the ListenTalk RF system has advanced encryption algorithms. We will advise you of the pros, cons and price differences of course.

Our digital infra-red transmitter is located in a central sound control room and a simple coaxial cable is looped between each IR radiator in each area or booth.

Our digital IR radiators in each theatre or area which are wired from the control room.

Our digital IR receivers either located in each theatre or distributed at entrances so delegates can move with them.
Usually a technician to take care of changes, power disruptions or whatever.It’s really very simple.
