INSTALLATION CONSIDERATIONS

LIMITATIONS IN VOLUME WITH HIGH MAGNIFICATION SETTINGS
Using an 8x setting limits the power to each speaker pair to one-eighth of the amplifier’s output.
In a typical application of IM volume controls, a system has eight pairs of 8-ohm speakers throughout the house and in
adjacent outdoor locations. Each pair of speakers is connected to an IM volume control with its switches set for 8x.
With eight pairs of speakers, one-eighth of the amplifier’s power is available to any pair. Therefore, an amplifier rated at
100W per channel RMS into 8 ohms will deliver up to 12.5W to each of the eight pairs – whether you play all eight pairs or
just one pair. This translates into a drop in the maximum volume capability of about 9dB at the 8x setting.
