Harman Kardon CA260 Owners Manual - Page 8

The CA260 is capable of operating as a 180 watt mono power amplifier when driving a 4 Ohm speaker system.When used this way, two units are required for a stereo system The instructions for connecting a stereo system using two CA260's in the bridged-mono mode follow: 1. Each amplifier will have one speaker system connected from the left channel positive( t ) terminal to the right channel positive ( + ) terminal. The left channel positive terminal should be connected to the positive termlnal of the speaker system. No connections are made to either of the CA260's negative speaker termlnals. 2. The input to each CA260 is made to its left channel input jack. In other words, the left channel output of the tunerldeck is connected to the left channel input jack of the CA260 driving the "left" speaker, and the right channel output of the tunerldeck is made to the left channel input jack of the CA260 driving the "right" speaker. 3. The bridged-mono swltch on each CA260 IS placed In the "on" position. Note: Only one speaker system with an impedance of 4Ohms,or two speakers with an impedance of 8 Ohms each, can be used in the bridged-mono mode. Also, only speaker systems with a sufficiently high power rating can be safely used. Systcm Left channel Speaker System Tuner, Deck 9 Left chaririel
