Pre-amps with variable high and low pass filters?

[Lew3vans]

Hi i would like to know some options for a decent pre amp with variable high and low pass filters. I have seen Emotiva PT2 has this feature (for example) but I am struggling to find others.

Do you know of any you might recommend?

£1800 max would be the budget.

Sorry. I only know of AVRs which have even more than just a high/low pass, but fit your budget. Just use their preouts.

Sounds like the Parasound P5 or P6 would fit your needs.

Do you mean high and low pass filters with strong attenuation, for example for crossovers? Or high and low pass filters with mild adjustable strength, for tone controls?

Really just to cut the low end signal going to the speakers to minimise them trying to reproduce sounds they aren’t great at.

And to se the crossover point for the signal to go to the bass.

That’s exactly what I was looking for.

Shame they look like they were designed in the dark 40years ago!

I will still consider it though!

miniDSP Flex?
DAC rather than pure pre-amp but you've not specified the source you want to use, so it may be appropriate

 

[ampguy]

SMSL A300 very little tweakability but works for me

Thanks for the reply.

It would be for multiple sources.

I already have an SMSL SU-9 Dac which is great for digital source selection anyway between main inputs from ROON (usb), Sonos (coaxial), TV (optical)

But I also have analog inputs…. Turntable and rca in from a set of decks.

I’m sure there would be a one solution fits all out there! But I really do like the SU-9 coupled with the SH-9 headphone amp.

It I then want to run 2 mono amps from it

Bit of a messy set up I guess!

Fortunately, they look much better in person. In fact, I quite like the look of the silver units.
I have the P5 and contemplating getting the P6. The connectivity factor alone, makes it hard to beat or maybe i should say, anything comparable in its price range.
Great thing is, almost any place that carries these, offer a pretty good return time. However, I think after one gets said unit, unless there is an issue, I doubt you would want to return it. The flexibility alone, is what done it for me. Sound wise, I have zero complaints.

Doesn't the little Marantz NR1200 do what you want?

I’m not sure to be honest I have had a look at the spec sheet and can’t see that it has adjustable filters/crossovers

Hope I didn’t offend! Apologise for criticising in an abrupt way!

Absolutely not, I didn't find anything offensive or criticizing about your previous post. So, you're all good.
Besides if someone finds something unattractive, then there's nothing wrong with that.

Download the manual and take a look.

Thanks been though and it only has low pass. Seems a good piece of kit though!

Perhaps a MiniDSP SHD:

Minidsp SHD Review Updated (DSP, DAC & Streamer)

This is an update to the review of minidsp SHD that I did a couple of years ago. My tests have evolved since then and company has stated that they fixed a few issues I found in that test. The SHD costs US $1,195 and includes a USB DAC, streaming engine (based on Volumio) and of course, DSP...

Minidsp Flex Review (Audio DSP)

This is a review and detailed measurement of the Minidsp Flex audio signal processor. It was sent to me by the company and costs US $475 for unbalanced and $550 for balanced that I tested. Flex borrows the interface from SHD and puts it in a compact package. Seeing how I really liked that...

Balanced version, there are several configurations.
Even an 8-channel version, I built a 3-way active DSP speaker with a Flex Eight:

Active DSP DIY speakers, for testing a few ideas

FFLOTSAM (Fabricated From LeftOver Things Studio Active Monitor) Active DSP speakers, for testing a few ideas I had some stuff lying around; a few random Baltic Birch-ply panels, some countertop material, a few cans of partially used brown spray paint, and some not-too clumpy spar varnish (that...

I use the two remaining channels to feed a parametrically EQ'ed signal to a headphone amp.

I'm also using the Flex Eight to EQ a JBL D2 Horn:

I have been interested in the Project M2 DIY Thread for some time. I helped a friend install a fabulous home theater with 708i, but I have been fascinated by the M2. Recent reviews of the 708i were interesting, especially given my positive impressions of the speaker. Erin's review of the M2...

I going to build a pair of JBL M2 clones using a MiniDSP crossover. There are even FIR filters available for JBL M2 clones available on their FIR forum. They have a good community, and app notes about multi-sub integration, REW, measurements, etc. I've built several speakers with their kit and it has been a really good experience.

Hope this helps.

As an alternative to a pre-amp with high and low pass filters: many subs have high and low pass filters built in. Pre-amp out to sub; high pass from sub back to amp; or in my case with passive subs, to satellites (L&R speakers).

That is so stupid! Almost all subwoofers include the low pass filter already. I don't know what these manufacturers are thinking by doing this, but it seems many of them are doing it the same stupid way.
