do you have a manual for the stereo one Jack?
The Dualcore is the stereo one Ron, the other 2 are for mono only, it's just one takes a mono signal from say a surround sound processor and the other takes a stereo input and outputs to a mono sub. It is possible to use 2 subs though using the phase inversion switch on one of the subs (or connecting one out of phase) which would work fine.
here are some connection examples for the cheaper units.
Heres the manual for both cheaper units.
good man thanks
Here is a great FAQ for the Dualcore, the product is evolving fast via firmware as users expand and the feedback comes in regarding devices connected to it and users needs, the company seems more than happy to change and add to the firmware in the direction of what the customer wants. It's quite refreshing to deal with them!
YHPM regarding the input sensitivity setting.
I was surprised to see I had missed a few updates already; as you say they seem to be very keen to keep the customers happy.
I got one deliiverd last night, Great personal service from Jack. The Dual Core is so easy to set up and use. I have been thinking about addressing room issues for a while. now. Bass was getting boomy at higher volumes.
Previously I had My Laptop, Sky box and BDP hooked up to the Digital in connections on my Wadia 861. I wanted to be able to use the DSPeaker on all these so I got a 4 to 1 remote S/pdif splitter. I also connected the Digital out from my Wadia to the splitter. I then connected the single output to the DSP in and out to the Wadia DAC S/Pdif in.
I used the RCA analogue in and out for TT duties. ( you can also select analogue in and digital out, sending your TT through the Wadia DAC.
First attempt at running the test tones had my TV and Guitar vibrating like hell. After curing these problems I ran the Room set up again and the bass problem is gone. Mids and highs are also cleaned up. Great result. messing with the House curve etc features now but it got it pretty much right first time. No lack of bass, just less wooly.
Pretty flat now .
Seriously considering one of these for use with a tapped horn, to run 20-50hz under the Tannoys.
Question - I'm thinking the tapped horn can be mono at these frequencies, would I need the mono or stereo one? (would be stereo out from the integrated - assuming I can get the V20 modded for to give a pre-out - but mixing down somewhere along the line to mono before going into a separate amp for the tapped horn (most likely a Topping like Speedysteve uses) and into a single mono speaker driving the tapped horn enclosure.
I'm assuming the correction unit will ensure a flat cure to 50hz without me having to mess around with the Tannoy crossover? (If i went up to 140hz I'd need stereo tapped horns and alterations to the crossover).
The difference between theory and practice is greater in practice than in theory.
