SYSTEM CONFIGURATIONS
MULTIPLE AMPLIFIER CONFIGURATION
For the audiophile, there is the possibility to install three stereo (2 channel) amplifiers and achieve
unparalleled sound quality. Using the optional remote control, you can also run the gains of all
three amps up and down together from one remote.
Performance is tremendous since you are dedicating individual amplifiers to parts of the music
spectrum thus gains and tone controls can be adjusted independently to achieve a truly balanced
sounding system.
