More sensitive subs, not higher power. But what I did was put a fixed 6dB (2x) gain stage between the sub outs and the amp feeding my subs. If you have an old preamp laying around (or in my case, a miniDSP 2x4 that the NAD obsoleted), that will work great. If you're handy, just a couple of flat noninverting aps fabbed from a couple opamps will do great.
Thanks SIY - that's an interesting take, one I didn't know was possible. Essentially boosting the line output correct? I am handy, but knowing how to stitch the couple caps and opamps into a solution is probably beyond me in this case. Any out of the box solutions I should look out for, or is this something that has to be custom fabbed. Alternatively, in looking at the miniDSP, 100 bucks isn't much to solve the problem. Seems like a lot of tech for seemingly simple need though.
Yeah, that's why I grabbed a miniDSP, I just didn't have the time to build something custom. But really, any used preamp will work. Set it for 6dB gain, then forget about it.
I had an M33 and my two subs would not come on until the volume was cranked way up. I don't understand the pitiful sub output from such a pricey unit and ended up returning it. However, i was told that I could use a Y splitter to allow you to plug into both the L and R inputs of your sub and this apparently doubles the voltage into your sub(s). I'm not 100% on this so perhaps someone could verify. cheers
I would already avoid the M33 subwoofer function for the reason of the not yet fixed distortion problem, because even the temporary fix Tone Control = ON reduces the max output power. Simply connect the subwoofers via the pre-outs of the M33, there you have a higher output voltage, and adjust the necessary settings directly at the subwoofers.
Will Dirac manage those outputs as well? or are those outside of the DSP?
Ok, I'm gathering then that you meant the second set of speaker outputs. Not the two preamp outputs (left/right) RCA's. I'm using powered subs as mentioned, so that obviously won't work here. If I'm misunderstanding here, please clarify. But if DSP is not applied on the preamp outputs (RCA's) then it kinda defeats the purpose of DIRAC with subwoofers. That becomes an unreasonable solution.
It is.
It works for me without any problems. Which BluOS version do you have on the M33? Have you ever done a factory reset? An update via USB is not really necessary. Simply connect to the network.
I tried the factory reset and still no luck. Hard to believe I have two bad cards. Once again, the USB Module works fine so something is funny. Any other thoughts?
