new DSP for US market

Not open for further replies.
Not at all. DSP6 has 3 pairs of line level outputs. You can configure them in any way you that want, and a common way would be:

Outputs A --> woofer
Outputs B --> midrange
Outputs C --> tweeter

The built in amplifier can be used with "Output C". This is just an OPTION and you can use your own amps for each of the "Outputs"

You can use the built-in amp not only for tweeter but anything you run from Output C. Output C can be configured with the crossover and EQ functionality just like Output A and B.
 
I am considering one of these as an alternative to the MiniDSP 4x10 HD. Seems like a good option with the built-in amplifier for powering my tweeters. I can use my 300B amp for my midrange horns and a high-powered solid state amp for my LF drivers.

How is the noise floor, frequency response and convertor quality? I like the ability to run both digital and analog sources through this thing.

I have not compared to MiniDSP. However, the DSP-6 sounds very good. It compared favorably to more expensive units -- Najda DSP and XTA dp226, actually the DSP-6 sounded more natural and less "digital" than both of the above. Noise floor is extremely low, probably much lower than any tube amp.

It will take both digital and analogue in. I have not used digital in, so cannot comment there on SQ.

I am not sure what you mean by "frequency response".

differences between MiniDSP and DSP6

MiniDSP (most versions) all crossover and PEQs are done in IIS. DSP6 PEQ is FIR. However it is 6 bands per channel, where miniDSP is probably more bands. It isn't clear from Reckhhorn specs whether the crossover is FIR or IIS.
 
I hope you can confirm this (FIR on crossover). If so, this product (as presented on paper) has features(FIR) I am looking for (sure hope the ADC and DACs are good quality). MiniDSP requires a MiniShark system to do FIR on both those. I use a DEQX on my main system, but want to build another smaller system and can't afford another DEQX at current prices.
 
pos,

Here is the response from manufacturer:

1. DSP-6 has minimum-phase. Linear phase technology including HP, LP all EQ and time delays are available for Studio only for above US$ 5000 hard & software.
Further comment: Every setting must be tested by listening. If you hear no difference - no technical details will help you. If you hear a difference - you must be able to decide if the result it is better or worse for the given speaker. Generally spoken: The positive effects of DSP-6 to improve every speaker outnumbers the negative points more than 100 times. You must compare it with active analog filters or passive filters. If you want digital studio quality you must pay much more.
I suggest the below video for best explanation of Linear Phase vs Minimum Phase:

2. Taps = EQs?
We have 5 parametric EQs each of the 3 stereo groups.
 
Clarifying Manufactures data on DSP-6

Generally IIR filters are called Minimum Phase, and FIR are called Linear Phase. According to the previous posts, the manufacturer says theirs are Minimum Phase and FIR. That seems to be a contradiction. Any clarification would be helpful. The manufacturer claims their crossover sounds better than other (who?) by over 100 to 1. I am not saying they don't, but the Minimum Phase and FIR seems to be a contradiction.

I should add that there is disagreement of some recording engineers as to which sounds better. In theory, Linear Phase will maintain the synchronization of sounds at all frequencies, (a plus), but also have received criticism of generating "pre echo" on the start of some transients (a minus). Which sounds better is strongly debated, and varies by the test and program material used. Using a DEQX (which does use FIR EQ), personally I find the results amazing in creating a coherent image, but the DEQX is indeed powerful/expensive and creates very finely detailed correction curves (a lot more than 5 PEQ bands can.)

I am not picking on the manufacturer, just seeking clarity. 🙂
 
Please excuse the misinformation.
After further correspondence with the manufacturer below is the accurate response:

"our previous information = FIR filter was based on a German Magazine review. But the factory had just confirmed that we have IIR filters which I believe is true."


The DSP-6 is IIR filters.
