Each loudspeaker can be ‘tapped’ to receive a specific voltage, making individual
control of the loudspeaker output possible. Take care to use the correct tap
setting for the output voltage of the amplifier you are using. In the case of
SmartAmps, which can drive either 70 or 100 volt lines, the 70 volt setting is
recommended.
The total number of loudspeakers it is possible to connect to a single amplifier
channel is determined by adding the total wattage of the loudspeakers together.
For speech systems, where low frequency response is not critical, these systems
can offer extremely good value for money.
A 100 Watt amplifier running at 100 volts can drive 100 loudspeakers tapped at
1 Watt, 50 loudspeakers tapped at 2 Watts, or 2 loudspeakers at 50 Watts and
anywhere in between. Up series loudspeakers have a wide range of transformer
taps to choose from.
