Harman Kardon AVR 146 connection to Subwoofer?
I just got a Harman Kardon AVR-146. Everything was OK until I got to the Subwoofer connection. The AVR-146 has speaker connections for the center, left, right, left-surround, and right-surround. But for the subwoofer connection, it has what looks like a purple component connection. Its completely different that the other outputs from the receiver. The Polk subwoofer I have is expecting the same connection as the other speakers. Am I missing something? Please help.
That purple connection is a standard line level subwoofer output. This is the best way to hook up your sub. You will probably have to tell the receiver in its menu to send this signal to the sub. Your Polk sub almost certainly has a line level input. If it only has speaker level inputs just send the speaker wire to the sub first. The sub should then have speaker level outputs that pass on the signal to the main L&R speakers. This connection usually passes the signal through a crossover. If you want to avoid this you can send the signal to the sub from the "speakers 2" output on the receiver.
