eq215x and ax-406a

Hi just got a couple of questions. This is the order the components are in line.
HU->EQ->AX-406A-AMP

rca from hu-> input on eq
aux output from eq to input on x-over

I've set the voltage from the aux output and reading 6.5 v on the rca's. These rca cables go into the input on the x-over. With everything wide open on the x-over (the input level controls and the output level controls on the x-over i'm getting nothing showing. Is this normal?

Thanks
kevin

No, that's not normal. Make sure your RNETs are seated properly, without them you get zero sound. I had one of my RNETs sit a bit loose and it caused my sound to cut in and out when it would gain and loose proper connection. I fixed her good.

do you know if your xover was working before this? lights come on, power plug is all the way in

Been away all weekend. To the ones who've posted so far.

I've not checked the rnets to make sure there seated properly, but here is the thing though. With the eq aux outputs running into the x-over the x-over is getting around 7 volts. I can't turn the gains (input that is) on the x-over up before it starts clipping at this point. Now I "can" turn the output gains on the bandpass section of the x-over and the speakers get louder. Keep in mind everything is on flat, 0 and turn all the way down on the 2125 too!

I'm getting sound from the 3-way configuration, it's just I find it really odd when i check the voltage that it's just basically at 0.

Does the output levels on the bandpass, high, low on the x-over act as a line driver (amplifying the input signal?).

The x-over was working before. All lights come on, etc...

Thanks,

Kevin

How are you measuring the outputs? Maybe your crossover doesn't ground the RCA shields... try probing ground elsewhere, and make sure you are using a 60Hz tone!

You know, I my need to try to ground elsewhere then. I'm playing a 60hz tone at 0db.

Ground probe at the rca shield and positive probe at the rca connector pin. Those terms just don't quite sound right atm, lol. Anyway, the way i'm testing is the way you described or someone else in a past post.

On another side note, I just found out that i've got a 100hz rnet on the u23 chip so I've gotta try and find a 60-70hz rnet to replace that. I think i'd rather have my midbass drivers go down lower than 100hz. What do you think?

Thanks !
