Does this work with DSP pro? I figure they've changed it by now.

This is the next thing I have to Build :-) a couple of the last posts here are using the mini din plug and it should work with the DSP pro.

You ever give this a shot? How'd it work out. Gonna try this with my Pro. Thinking of taking apart my URC-2a and making it less ugly

I haven't yet... I'm still using my URC also. I'd consider taking mine apart too but I'd like to really have a metal knob that sticks out a little more rather then a thumb wheel

Cool, thanks for the response. I'm with you on the knobs, I got some aluminum ones Ima try. Let you all know how it turns out.

I ordered a Director... Any idea if I can have a potentiometer within arms reach for system volume control and put the director say in my sun glasses holder and just use it for input changes?

Default Re: How to make your own Remote Controller for Helix and Brax DSPs

I wanted to say thank you to this group for all of the good information about this unit, and to give an update.

I have the Helix DSP Pro, and the information is accurate for the pinout as of this posting.

I'm using a digital potentiometer to control the Helix, and in my findings, 10k just isn't enough. Even at 0 which reads about 9.5k on the multimeter, signal is still passed over the RCA from low to high. In order to get the volume to totally stop I had to have a resistance of 55.7k.

In my findings, the basic steps are 55k, 53k, 37k, 25k and then every ~407 ohms from 25k up to 300 ohms has a noted increase in volume. My source unit only has 64 steps so its possible the increments are even smaller than 407 per step but thats roughly 1db when measured with my SPL meter.

If you use an analog potentiometer this might not be an issue if it goes to a complete circuit disconnect at 0.

I hope this helps someone else. I had to combine a 10k and 50k to get this working.

It would be MIGHTY helpful if anyone knows the DIGITAL control and not the analog one. I cant believe the Director unit is using the analog like the small remote does.

Question Re: How to make your own Remote Controller for Helix and Brax DSPs

Installing my DSP Pro today.

What type of connector do I need to connect to the processor?

Also what type of switch do I use if I want to be able to toggle between the two presets? I am assuming a toggle switch would not work, correct?

Looks like an 8-pin mini din connector such as this recepticle I saw on pg1 that looks like the port on the DSP:


Maybe something like this:
