Public Address Systems

We offer a full design, manufacturing and equipment supply for Public Address systems.
Our range extends from simple desk mounted systems, for use as an  example in small retail outlets, to full networked DSP based mixing, routing and audio processing systems.
With this range of hardware and software solutions, we can offer a design which gives  a performance to price ratio which is unequalled.

We can also provide a full design service for both loudspeaker types and distribution from drawings to site survey. 

Amplifier specifications are detailed below.

6 INPUT CHANNEL PREAMPLIFIER

Six balanced-switched inputs are provided, all with selectable sensitivity, phantom powering and fully configurable priority ladder.

A unique dual audio path architecture allows each of the six inputs to be routed to either of the two pre-amplifier outputs via phono sockets on the rear of the unit.

24 volt dc battery backup facility is included and also a 24 volt dc, 250mA output supply. Volt free relay contacts are  provided from the first four input channels for relay switching, busy indication's, volume restoration, etc.

Front panel indications include an audio level bargraph for each output.

Features

• Selectable sensitivity (10mV, 200mV or 770mV @ 600 ohms) and phantom power on all inputs
• Fully configurable audio routing and priority ladder
• Two configurable pre-amplifier outputs
• 24V dc backup
• 24V dc, 250mA output supply
• Output relay contacts
• Bass, Treble, individual channel volume and master volume controls
• Rackmount kit, connectors and manual included

 

6 INPUT CHANNEL 250W MIXER AMPLIFIER
