The general concept of a 100V line loudspeaker system is that a quantity of 100V line loudspeakers are connected in parallel across the amplifier output terminals. The loudspeakers may be arranged in any order, any combination and if necessary, using any number of feeds from the amplifier. They may be grouped onto sub-circuits which may then be controlled by switching or group volume controls, etc., as required to suit the operational requirements of the system. Sub circuits may be dedicated to ëPage-onlyí operation and switched in by means of relays powered by the comprehensive MACRO current sinks. See APPENDIX C for typical arrangements.

The 100V line loudspeaker output terminals will deliver conventional full program content, i.e. all music and all paging/priority signals. For 100V line loads connect between the two outer terminals and for 50V line systems connect between the centre and right terminals.

All three 100V line output terminals fully floating, earth-free, and centre-tapped. This latter is useful in certain critical installations where careful balancing of the loudspeaker network may be necessary. The terminal marked ëCTí may be earthed to chassis if required.

Low impedance output

Power output to the loudspeaker load may be taken at low impedance (low Z) The terminals marked A-O-B present a very low impedance output across A-B and which is centre-tapped at O. These terminals are not specifically rated, but as a guide, the output impedance across the A-B terminals is in the order of 2 ohms. The centre-tap is a direct connection to 0V level (chassis, signal earth, and -24V).

Typical loudspeaker load arrangements

 

 

The following are acceptable examples of loudspeaker loading arrangements:

A

400 x 1/2 Watt 100 Volt line speakers =

200 Watts total load to the amplifier. Use a 250 Watt amplifier

B

200 x 1 Watt 100 Volt line speakers

=

200 Watts total load to the amplifier. Use a 250 Watt amplifier

C

2 x 50 Watt 100 Volt line speakers =

100 Watts total load to the amplifier: Use either a 100 Watt amplifier (or a 250 Watt

 

amplifier to allow for 150 Watts future development).

D12x 5 Watt 100 Volt line speakers = 60 Watts total load to the amplifier, and therefore 40 Watts spare capacity for future expansion if using a 100 Watt amplifier

E10 x 5 Watt, and 6 x 2 Watt 100 Volt line speakers = 50 + 12 Watts = 62 Watts total load to the amplifier. Use a 100 Watt amplifier.

F4 x 60 Watt units each tapped at 30 Watts, and 20 x 4 Watt units tapped as follows: 5 @ 4 Watt, 5 @ 2 Watt and 20 @ 0.5 Watt 100 Volt line speakers = 160 Watts total load and therefore 90 Watts spare capacity for future expansion or for final adjustments. Use a 250 Watt amplifier

See APPENDIX C for typical loudspeaker arrangements.
