Processor Options

Update on the Pioneer ODR referenced on page 1: I am now running one in my car, and the only caveat is that pioneer's "optical" bus is some type of proprietary non-optical digital interface. So, I'm just running analog into the unit via IPbus adapter.

Beyond that, the processing is very nice. Fully configurable 4-way crossover, with adjustable points and slopes (slopes adjustable in 6dB/oct. increments from 6 to 36 dB/octave) Furthermore, the slopes are independantly adjustable on each end of each band. Over- and underlap are also possible with this crossover. It is able to adjust the level of each band, as well as running in 2 or 3-way mode. Time alignment and phase for each band are also adjustable.

The internal EQ can be set up in 2/3 or 1/3 octave resolution, in addition to the standard bass/trable adjustments found on most HUs.

Finally, the level of each source can be adjusted to match the others, using FM radio as the reference. (No more volume adjustments when switching sources!)

Basically, for the money, I'm pretty happy with the unit. I also have a P1R laying on the shelf that I got in a package deal with the ODR. This has many of the same features of the ODR, with a more limited X-over and EQ, but is contained in a single DIN chassis rather than DIN + external enclosure.

other option is the alto mobile drive20 or drive30

I feel ya. I've been considering the audiocontrol stuff untill i found out the price. Freaking $300-600

For that I'd rather just get the alpine


Sigh, im stuck undecided on what to do

I'm thinking EMU 0404 usb - optical toslink - some kind of dsp.

I dont care about dolby. I would like time alignment and EQ. I dont care much about crossover controls as i can set that at the amp, and im keeping my passive component crossovers.

I just want to be able to have optical input to 6 rca channels out at a decent clean voltage with good sound quality.

if you find it, let us know...;)

btw - why RCA, you can make your own cables...so why limit yourself? why not 1/4" or 1/8"?

I have good quality RCA cables already. Less work/time/money

plus I dont really like 1/4" 1/8" connections. I find them noisy most of the time. Id rather have a seperate connection for each channel.

1/4" and 1/8" can still be individual channels...just like RCA!

btw - what RCAs are you running?

I used a drive 30 for awhile in a previous car audio setup. It has some slight noise issues but with some playing on the gains I eliminated the majority of it. I would think it would be a better choice then the ucs for carputer use as it can be adjusted via serial cable on windows pc's. Prices are around $500 new. theres been some discussion on eca about the Behringer, but I haven't read much of them myself. I'm trying to decide if I want to do a carputer and sell all my spendy gear and do something a bit smaller in my pickup or not...wweeee!

Any sigificant differences between the Alto mobile UCS and the Drive 30? looks like they both have serial cables

There is a big thread going on right now about using the PC for EQ, time alignment, x-overs and using outboard DACs to run the signal to the amps. No external processors needed. Not very expensive either, computer cost=?, DAC cost=$140 per 2 channels. A 2 way setup would need 2 DACs, a 3 way, 3 DACs. This setup should be super high end, better than all the processors in this thread.

Good stuff is at the end.

UCS has more crossover slopes,burr brown's,more gain adjustablitly, one less output, cant assign outputs to whichever input you want though.Drive 30 has higher output levels.Lower input levels...Just what I see from a glance. Also if you have not computer the ucs needs a progammer, drive 30 has a built in display.

From what I have heard and read, there were grounding issues inside the Alto 30 unit that causes ground loop noise. SOme people have managed to get them to work noise free but the S/N ratio is pretty low on those.

Here's a new option. The Precision Power DCX-730. People over on diymobileaudio.com seem to like it. There are a few reviews of it.
