CONSTANT VOLTAGE DISTRIBUTION SYSTEMS
25 VOLT AND 70 VOLT CONSTANT VOLTAGE DISTRIBUTION SYSTEMS - In applications requiring a large number of speakers that
are located at a far distance from the amplifier a 25 Volt or a 70 Volt Constant Voltage method is most widely used.
MAIN ADVANTAGES IN USING THE HIGH IMPEDANCE METHOD
1) All speakers are connected in parallel usually on to a single speaker line.
2) The Amplifier Output Voltage is constant over a very wide range of load impedance.
3) The Amplifier Output Voltage remains practically constant if loudspeakers are connected or disconnected from the line.
4) Different acoustic power can be allocated in each area as required by using the power taps on the speaker line transformer.
5) Since the system provides a higher voltage at a lower current, resistive loss in the cable is reduced resulting in a higher efficiency.
6) Calculations of the output power needed and the speaker power requirements are simple and easily accomplished.

INSTALLATION TIPS
1) Determine the amount of speakers required for the
installation and their location.

2) Choose the power output needed for each speaker (typ-
ically 1.25 Watt for background music applications and 5-
70 Volt 70 Volt 70 Volt 70 Volt
10 Watt for paging horns).
