This device helps protect the telephone systemin event of an equipment failure causing a dangerous voltage to be fed to telecom line. The unit contains devices which are activated if a voltage between line and ground exceeds the correct level, they also in turn place a short circuit from line to ground protecting telecom line and causing two integral fuses to be activated which isolates telecom line from the fault.

SOUND DISTRIBUTION EQUIPMENT

STUDIO ROUTERS

SIX WAY PLUS ONE ROUTER Unit allows any number of the six stereo signal sources to be routed to air. If no source is selected, unit automatically reverts to a stand by input ( sustaining service). Each studio is provided with an illuminated panel mounting latching press switch to connect studio to 'air'supplied fitted in individual plastic enclosures.   Unit provides unity gain and is designed to work with inputs of standard 0dB (PPM4 ) input impedance to V.E. mixer stage 10K. Output unbalanced to drive into 600R or greater. Alternative model available with transformer isolated balanced output to drive into 600R.   An auxillary 24 volt at 5m/a max. switched feed is available to drive external opto-couplers for mains powered 'ON AIR' signs etc.If required an alternative unit fitted with six integral opto-couplers is available to drive mains powered signs etc.which are not fitted with integral opto-couplers.(max current 1 amp at 240 volt).   ALL VERSIONS MOUNTED IN A.B.S. ENCLOSURE SIZE 380 x 300 x 120 mm. ALL SOCKETS MOUNTED ON SIDE WALLS OF ENCLOSURE. ALL AUDIO INPUTS AND OUTPUT X.L.R. CONNECTORS. CONTROLS MULTI PIN CONNECTOR. MAINS INPUT STANDARD I.E.C. CONNECTOR.

STUDIO TO AIR ROUTER SYSTEM THE EASY WAY TO CONTROL OUTPUT FROM ALL STUDIOS   WHAT DOES IT DO? Logic control enables either one or more studios to be put on air at the same timebut only with the authorisation of the 'ON AIR' studio. Each studio control unit incorporates a visual display which will instantly advise the presenter of the studio, if it is 'ON AIR'? At the same time the visual display will indicate if a second studio is feeding the system or a studio requires to be allowed access. Each studio or signal source is provided with a four button control panel which connects to the master controllerand can be fitted in most types of mixing desk. Panels supplied fitted in individual plastic enclosures. HOW DOES IT WORK ? If system is powered up and AUTHORISATION button illuminated the system is ready for use. If no button except AUTHORISATION is illuminated the studio may now claim the station output by pressing the STATION button. This will cause the STUDIO button to become illuminated plus STATION buttons on all other terminals. Your studio is now 'ON AIR' This will cause all authorising buttons to flash. Identification of the studio requesting access If you wish to obtain access to the on air circuit already being used by a studio, you must press STATION button on your console followed by REQUEST button. is made easy by differing flashing sequences. If the 'ON AIR' studio accepts your request they will press their AUTHORISATION button which will cause your STUDIO button to illuminate. You are now 'On Air'. Only an 'ON AIR' studio is able to authorise access to the transmission circuit. Non 'on air' AUTHORISATION buttons will not function.To take studio off air press STUDIO button.

PUBLIC ADDRESS POWER AMPLIFIERS

FOR USE AS SOUND RE-INFORCEMENT IN THEATRES, PUBLIC BUILDINGS, FUNCTION HALLS, EXHIBITION CENTRES ETC. Available in varying power ratings from 100w - 300w per channel in mono or stereoThis range of Mos-Fet power amplifier modules offer high quality audio power. They are used nationally and internationally by professionals in the leisure, disc, public address & studio industries where they are well known for their quality,reliability and performance. The 100w 100volt line models have successfully found a niche in hotel and hospital sectors. The latest Mos-Fet devices have been utilised, together with a sophisticated circuit design. The amplifier is fitted with special protection circuits to minimise the possibility of damage to the output devices in the event of an open or short circuit to the transmision line, these factors result in exceptional clarity and realism which is essential to compliment today's high-technology sound equipment. As reliability is of prime importance, generous power supplies are employed incorporating a toroidal transformer and glass fibre printed circuit board mounted on solid aluminium chassis with extensive heatsinking.These features, and many more combined with rugged construction, deliver a superlative level of reliability.
