Audio Design Services Ltd., St David’s House, Adcroft Street, Higher Hillgate, STOCKPORT SK1 3HW. INTRODUCTION Features The ADS 5240 is a 240 watt rms, 2-zone, mixer amplifier, ideally suitable for powering medium and large sound systems. The technically sophisticated, built-in features, allow a wide range of applications at a competitive price. Further, the design features make the amplifier one of the simplest to configure and install with no internal adjustments or retrofit options required.
Safety Information WARNING – THIS APPLIANCE MUST BE EARTHED IMPORTANT The wires in the mains lead are coloured in accordance with the following code Green and yellow Earth (E); Blue: Neutral (N); Brown: Live (L).
Audio Design Services Ltd., St David’s House, Adcroft Street, Higher Hillgate, STOCKPORT SK1 3HW. OPERATION General Installation • ALWAYS ensure that the equipment is properly earthed (grounded). Operating without an earth is dangerous and may cause high levels of audible hum from the speaker outputs. NEVER remove the top cover of the amplifier or make an internal adjustment with the AC mains supply connected. All internal servicing should be performed by a competent and qualified engineer.

Priority Connections Input 1 Closing the priority contacts directly below input 1 will cause all other inputs to be muted by greater than 40dB Inputs 2–5 Closing the priority contacts below each of inputs 2 to 5 will cause all other inputs to be muted assuming no other input was already accessed. These inputs operate on a ‘firstcome-first-served’ principle; priority will not be established if another input had gained priority by being used first.
Input Options Input 1 Input 1 has four options, each selected by a set of slide switches located directly below the input socket. The option is turned on with the switch set in the upper position. The options are • VOX – allowing a Voice Operated Switch facility to be used. When this facility is turned on, any signal (such as speaking into a microphone) above the threshold level will cause all other inputs to be muted. When the signal is stopped, the other input levels will gradually be restored.
Tape Out This output uses a phono connection (see Rear Panel No.17 on Page 8, labelled TAPE OUT – phono connection diagram below) Pin (Signal) Sleeve (Screen) Two phono sockets are available. These are connected together internally and provide a fixed mono output, independent of the master gain control. Loudspeaker Out It is possible to connect 100V line loudspeakers or 8Ω low impedance loudspeakers (see Rear Panel No.14 on Page 8). Under no circumstances must the two be mixed.
Facility Terminals dc Output The two top terminals of the four terminals labelled FACILITY (see Rear Panel No.15 on Page 8 and diagram below) provide a 24V current protected output, which can be used to supply external devices (such as relays or line pre-amplifiers) to a maximum of 250mA. Restoration The two bottom terminals of the four terminals labelled FACILITY provide volume restoration.
