Hi,
I want to know if I can plug my sub PSW202 in the speaker level input whitout any speaker plug in the output.
I want to use the B circuit from the receiver.
Thanks !

    No problems. Normally the speakers are in parallel with the amplifier when both speaker "A" and speaker "B" are used. So an example, one pair of speakers in the speaker "a" position (8 ohms), and one pair of speakers in the speaker "b" position (8 ohms). When the speaker "a" switch is on, the amplifier sees 8 ohms. When the speaker "a" and speaker "b" switch is on the amplifier see 4 ohms. So, speaker "a" sees a pair of speakers (8 ohms) and speaker "b" sees the input to the sub ( not 8 ohms, much higher) the amp will see an impedance greater than 4 ohms, so no problems. I can check at work tomorrow to see what the real input impedance of the speaker inputs are on the PSW202, but it is not 8 ohms, it is much higher, I think around 700 ohms. You can use a ohm meter to see with the DC resistance is when the + of one speaker and the + of the sub input are on the red lead of the ohm meter, and the - of the same speaker and the - of the same sub input are on the black lead of the ohm meter. Let us know what you find.:smile:

    The input impedance of the speaker in of the PSW202 is appox 2.2kohm. This makes the amplifier see just under 8 ohms, (approx 7.9 ohms) when speaker A in hook up to a 8 ohm load and speaker B is hooked up to the PSW202. Have fun.
