Does A21 Invert Signal?

[Craig Simon]

I have Infinity RS1Bs. I am using a Halo A21 for the woofers. The Infinity crossover needs to be set for inverting or non-inverting amplifiers. Does the A21 invert the signal? I can't see anything in the specifications that indicate such.

Thanks.

Hello there, if you are using an active crossover on the woofer but not on the upper you may have phase issues betwwen the two. Also, if you are using balanced for the bottom end and sigle ended for the top...or vice versa you'll have some phase issues. You could always set your croosover phase to normal and reverse your speaker cables on either the amp or speaker itself.

No, not normally. However, if you are using balanced cables where the positive and negative are swapped, this will happen.

If you have a sound level meter and frequency test tones you can mearure the speaker level out put at your crossover point. Play test tones just below, at, and just above your crossover point. Now reverse your speaker wire and measure the level at the crossover point again.
One way or the other should be 1 to 3 db louder at the crossover frequency. You want the louder setting.
