Be sure that total impedance of speakers and the amplifier is equal, do not raise
amplifier output power to above the permissible input power of speaker if the latter is
smaller then the former. If the amplifier output power should be raised above it, by
mistake, the speakers would be damaged.

When it is desired to operate the speakers from the distance over 50 m of the
amplifier, it is recommended that the line matchiong transformer be installed on the
speaker units to prevent excessive line losses. This method of load matchin known
as the cosntant voltage distribution system, eliminates the calculation of load
impedance and series-parallel speaker arrangemetns. In this method, all speakers
are connected in parallel.
These constant voltage outputs are most convenient for distribution of power when a
number of speakers are installed. Each speaker must have 100V line transformer
with a tap that gives the power desired for that speaker.
The total number of power settings for all speakers should be equal to the amplifier
power rating or less.
