xpa gen 3 and mini dsp

[hotrize]

Hi. I own a XPA GEN 3 5 channel amp. I also have a mini dsp 2x4 balanced. My question is that the dsp has adjustable input sensitivity settings,either 2.0 vrms or 4.0 vrms.The input sensitivity on the xpa is 1.5v into 8 ohm load.My speakers are Legacy Focus SE rated at 4 ohm.and the subs are SVS 16 ultras and paradigm servo 15.Which settings do I use.
Thanks hotrize

Your Legacy speakers are fairly sensitive. If you have too much gain, you'll be into the noise and may lack level control finesse.

Also? When they say balanced is 2 volts, for example, is that 1 volt per LEG or 2 volts per leg? Balanced of course, a 3 wire system with a Plus, a Minus and a Ground / Shield.

As for crossover settings? I'd start by mimicing the speakers crossover. For 3 way speakers with a single 2x4? Leave the mid/tweet crossover alone and split between the woofer and the mid/tweet.

For a full system? You might have been better served with a 2x8 'kit' which can be configured either single ended or balanced. And I think it also has a choice of sensitivities?

To cross to the sub? This'll get tricky, but you might experiment with restricting the lowest octave to the main speakers and crossing over to the sub a little below that point. Leave a 'gap', if you will, so they will sum flat thru the crossover.

You have a LOT of moving parts to get right. Do you have the Calibration mic and REW on the computer? Have you opened up the Legacy speakers to get to the drivers?

Get ready to experiment until you are tired of it!
