Panasonic SA-XR series HP filter for tweeter amp?


Speak-up

Recommended Posts

Hi, SA-XR users,

I'm seeking some advice from anyone who knows the circuitry of either a XR57 or XR70 that could help me with a crossover idea.  When in Biamp mode, would it possible to set up a 1st order high pass filter for the digital tweeter amp so as to bypass the need for even a capacitor on the speaker leads? I'd like to start with a high pass frequency of around 1.3kHz, first order slope for my tweeters(Stage Accompany SA8535's).  It would also lighten the load for the tweeter amp not needing to run full range.  Even the best capacitors in the world add coloration.  Worth a try, I'd think.

Thanks and I'm looking forward to any advice.
