Default Anyone familiar with this Lite remote volume kit?

V-03 (Holco) Stereo US$120.00

Click the image to open in full size.

Remote volume control board, using relay switching two set of resistor. 1dB per step, total 80dB, output impedance is constant, using Holco resistor, with four input relay and display, seperated voltage regulator board, with remote control handset, dual mono design, left and right channel fine turn or you can connect as single channel balance volume control, or add another sets to perform four channel control and max. up to six channel control.
board size: L 180mmX W 45mm
dsiplay board: L 230mm X W 52mm
I'm thinking of using it with a gainclone kit.

Thanks,
Matt

I bought this kit on eBay for $85 last year from a HongKong dealer selling as 18audioguy. It's likely worth this much.

N.B.: I don't know that the resistors on mine are Holco's (Brown, radial leads, colored dots on the tops).

While it is waiting for Brian's 4780 boards to ship before it goes into full time use, when I patched it in, the sound was similar to the Black Beauty in my system, although the remote is a cheap POS that will probably not last.

It does provide input switching, attenuation, and balance in one package.

Thank you for your reply.

What ohm did you get? I emailed the supplier and he said he can do 20k.

I wonder if the digital version would be better?

Not a lot of experience from me as I've only had the opportunity to hear one digital volume control compared to a plain old Alpha pot from Radio Shack. The RS pot was far better.

Maybe this one uses a different IC or is some way an improvement but I'd like to hear it before I invested any cash in it, or get a money back agreement if you don't like it.

The analog setup uses resistors that you can switch out if you don't like the sound.

Was documentation included? Was it difficult to setup?

Although the vendor quoted "constant 20k Input Z", it jumps all over the place (~10K - 50k) when switched through its ranges. I haven't measured output Z.

Instructions were a single sparse pictorial (I hope a pdf is attached). A little thought though, and no problem to connect.

One quirk is that balance can only be adjusted with the remote, not using the front panel buttons (unless there is some trick button combo I hadn't tried - there were no operational instructions).

the input impedance is not constant but after connect to the signal source then the impedance change is relative small.

Any speculation on how the sound quality would compare to the 3310 board? The 3310 board is a lot less expensive.

I think it should be possible to make make a relay attenuator board for a lot less than $120. Perhaps something like $50 for a simple, volume only board (with remote control)?

I haven't added the cost of all the parts, but I think it should be possible - anybody interested?

Best regards,
