I am a bit behind in my work so sorry about that. I’ll get them posted today but in the middle of a project. In the meantime, here they are for you.

Thanks for such a fast response.

143

Thank you, Paul!

144

so in serial and than in PS Preamp

You can use a speaker level or line level input to the first sub and then use the “sub out” XLR jack to connect to the XLR in on the second sub and so on, connecting as many as you like.

Subwoofers are one of the rare cases in audio where more is always better.

146

Chris, do you have a the time delay for the DSP of the F12? Usually these are 12-20 msec right?

147

My pleasure, kind sir! Exciting to get this project off the ground. Chris just went overboard on every aspect of this compact beast. I’ve never seen a woofer move air like that, it’s almost a little terrifying being next to it when he cranks up the signal generator to show excursion limits!

Can the wireless transmitter by paired with two different subwoofers, one for the Left channel and one for the Right channel. I.E. one transmitter and 2 subs, one for each channel.

149

Yup, the transmitter can run dozens of them and I think it’s the app that decides which is what. I’ll defer to Chris for this but definitely you need only 1 transmitter to control multiple subs. Pretty slick system.

150

the output of the wireless transmitter is summed to mono. Modern multi-sub optimization and EQ/delay etc assumes mono operation (for mitigating room modes etc). If you still want to run stereo, you can wire them that way but this isn’t assignable via the wireless transmitter

This is also to be compatible with other WiSA systems like that from Buckhardt and others.

151

Standard controls (volume, crossover, phase, auto on/off) are available on the rear panel of the sub, no app required. The app is for advanced setup (auto EQ, manual eq, delay etc) and controlling everything from your listening position.

152

No, the DSP part is very fast but the A/D then D/A has a millisecond or two of latency.

The thing that can be 15-20 ms of latency is some other brands wireless adapters or certain active speakers on the market using things like DIRAC live or advanced FIR filtering that can add audible delay.

Hello Chris:
I am definitely interested in subs for my FR-30’s. My equipment includes PMG Pre, PMG DAC, with Airlens, PW SACD. and BHK 600 Monos. I have a few questions:

  1. My understanding is that it is better to connect the sub via high outputs instead of lows.. Is it better to connect off the amps or speakers? or does it matter.
  2. Since it’s bass can you get by without exotic and expensive cables?
  3. I recall Paul mentioning about special connections for the then current BHK 300’s, something about grounding. How would connect to the BHK 600’s or FR-30 speakers?
    Thanks for your help and it looks like you got a winner with this new sub.
154

You’re going to like what subwoofers can bring for your system, even with the mighty FR30.

155

Nice! Would you say around 5 msec then for everything? Including ADC, PEQ and DAC.

156

More like 2-3. The wireless adds 2.6 ms on top of that.

157

Hopefully @Chris_Brunhaver can chime in on connecting the PSA sub from the BHK600’s versus from the FR30’s

158

Others may have had success, but I get only the title page for the sub manual.

159

All 3 work for me.

Thanks for running such a monster PS audio rig (all of the goodies).

  1. Some people prefer speaker level inputs (versus line level). It’s mostly a convenience feature - both high and low level input work great. The belief with high level is that it will bring more of your amplifier sound into the subwoofer sound but I wouldn’t say that other factors dominate how well a subwoofer blends.
  2. Connect to either amp or speaker terminals (to the sub) - whichever is closer.
  3. I wouldn’t generally recommend expensive cables for sub bass duty (I’d prefer to add more subs or a professional calibration) but everything matters in high end audio.
  4. That is a REL issue. We have floating bridge amps that didn’t play well with their high level sub input (because they were grounding out the negative terminal of the amp). This isn’t a concern on our high level sub input implementation.
