Harman Kardon CA260 Owners Manual - Page 9

Two CA260's can be used with two woofers (low frequency speakers) and two mid-high (or full-range) speakers to make up an "active" system, both amplifiers bemg drwen by the same tunerldeck. This type of system is con nected as follows. 1 Set the filter onloff switch of one CA260 to the "on" position. Then set the high passllow pass switch to the "low pass" position Connect the FILTER woofers (low frequency speakers) to thrs amplifier 2. Set the filter onloff switch of the other CA260 to the "on" position Then set the h ~ g hpassllow pass switch to the'lhigh pass" position Connect the mid-high (or full range) speakers to this ampl~fier 3. Connect the left channel input jacks of each ampl~fierto the left channel output of the tunerldeck. Connect the right channel input jacks of each amplifier to the r ~ g h tchannel output of the tunerldeck Note: If the tonal balance seems to be favoring either the high or low Irequency range, try using different line input sensitivity switch positions to make the best balance. For example, if the sound is bass heavy, set the line input sensitivity switch for the "low pass" amplifier to the "low" pos~tion.This will reduce the signal to the woofers (pJ Right channel Left channel LOW PASS 200Hz HIGH PASS / 12dBloctave \ 6dBioctave Speaker System Right channel Left channel .- - TunerlDeck Right channel ou~put Left channel output
