In-line 10 band PEQ without USB input

[ChurchSoundGuy]

Hello

I was wondering if anyone could point me in the direction of a particular device that is basically like a Fiio BTR13 (for the 10 band customisable PEQ) but instead of having a USB input, would be a jack input? Could be powered off USB or DC-in or battery, no real issue. Ideally similar portability as the BTR13. The idea is that i play drums in a band, and would like to have my monitor feed EQ'd to a particular curve that fits headphones/IEMs that i might use, similar to equalizer APO. Only real solution i could think of for having a sef contained powered device is something like a DEQ2496 but its pretty huge

Has to be a jack/xlr input tho, and can't use bluetooth output due to latency (playing live).

Any and all suggestions welcome, thank you!

What device is your monitor feed coming from?

Mixing desk but not particularly customisable PEQ wise.

I get the feeling something like the mini-dsp 2x4 HD would be along the lines, but ideally something smaller is what im looking for.

That's one requirement too many I'm afraid.

No thumb drive sized DAC+Amp with Line in and PEQ exists.

The closest things I can think of are:

-miniDSP PocketADC + Topping DX5II/JDS Element IV
-miniDSP 2x4HD/WiiM Pro + Headphone Amp (e.g. L30II)
-DIYAH Kameleon

Hmm

Any reason i couldn't use a WiiM Mini with a powerpack powering via USB port, or even my phone? 10 PEQ, jack input, jack output....

You could, but you'd still need a headphone Amp since the WiiM cannot directly drive headphones (Aux output is for external Amps only)

Could it drive an IEM?

It's not designed to handle low impedance loads.

Sound will come out, but the WiiM will be overstressed and is likely to change the IEM's tonality due to insufficient damping.

Output impedance I don't know. I'd say take the lowest impedance headphones/IEMs with the highest reactance (impedance swing) and calculate the impact of amplifier output impedance and make sure that the impact stays below 0.5dB? Somebody else can do the maths here, maybe @staticV3 or @oratory1990 feels like doing that

I chose 21 IEMs from @csglinux's database with especially low impedance and high variability and created this spreadsheet:

Output Impedance Frequency Response Deviation

Stereophile measured the Mini's output impedance at 33Ω, so you can put that into the spreadsheet and see the worst case frequency response impact.

THE WiiM Ultra has both digital & analogue in and out and 10 band stereo PEQ.

THE WiiM Ultra has both digital & analogue in and out and 10 band stereo PEQ.

The difficult condition is that it be tiny.

 

[ChurchSoundGuy]

Sweet, this could work then....

Desk jack monitor aux output > 3.5mm converter > Wiim mini aux input > peq through wiim > wiim mini aux out > 3.5mm to dual mono 6.35mm splitter > stereo belt pack headphone amp/ mini mixer > iems.

And not cost me £349 in the case of the ultra.

Could work but you will pick up some latency from the WiiM, it's not designed for live use.

Old Skool: Yamaha YDP-2006. It's six (per channel) fully parametric bands instead of 10, but fulfills all the other requirements. It's digital processing, balanced analog ins and outs, switchable pro (+4 dBU) or consumer (-20 dBU) input levels, settable levels, bypass, multiple sets of EQ settings, etc., etc. Channels can also be time-delayed. Just stereo. I have a couple and paid about a hundred bucks for each.

Appears to be really low from testing - aux in to aux out i don't think i noticed any perceptable latency at all.
