(16) Auto ON/OFF Switch
Use this switch to select between auto-on active and auto-on inactive (constant on) operation. For
maximum amplifier life, we recommend the Auto ON/OFF “Active” setting.
(17) Speaker Level Output Terminals (See Figure 5)
These connections send a crossed-over speaker-level signal to the front speakers. When connected
in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes the lower bass
frequencies from your satellites, enabling them to do a better job reproducing high frequencies and
giving your receiver’s amp more headroom (up to 50% more power).
You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you
wish to bypass this crossover.
