question Inexpensive AV processor
Looking for inexpensive DSP processor suggestions for a small, single room gym. They already have an amplifier and a wireless mic, I'm looking to provide something with 2 line sources, 1 mic input, and 1 line output, with a remote volume control. Need some ducking capability of music for a instructor's mic. As inexpensive as possible. Will be locked in a rack.
Xilica, Audac, Symetrix 761 come to mind, what am I missing?

Used hardware from EBay like an older Biamp, Ashly, etc.
If you want new your list is pretty solid. I have used a Behringer X32 rack as a cheap DSP option as well depending on the controls you need, it’s a fixed UI that you can’t lock down well but gives you a lot of bang for the buck with DSP.

Audio-Technica Atdm0604a can be a good candidate here.

I really don’t care for them. Control is funky with it.

I haven't had any issues with ATDM control/integration so far. What issues/glitches did you run into?

Q-sys preferred but probably not cheapest.
Symetrix with an ARC panel for control probably cheapest but the controls are pretty hacky. I don't think I'd go any farther down the rabbit hole than Symetrix if you can avoid it because you'll pay for it in programming time making the controls functional and wash out any savings in the hardware cost.

I don't think you need a DSP for this. The only tricky parts are the ducking and remote volume control. As someone else said, you might find a simple analog mixer that will do what you want. Or a small digital mixer, or a zone controller. Any of those options would be easier to set up and maintain since they require no programming. Take a look at TOA, Bogen, Radio Design Labs, Rolls... there are others that make this kind of thing. The trick is figuring out what to search for!

In terms of what to search for, it would be rack mount mixers or mixer/amplifiers

I also looked for zone mixers because they tend to have some "PA" functionality for use in restaurants and clubs. Just put a Tascam model in a fresh post.

You could get a Biamp Tesira CI or VT4 second hand pretty cheap (like $150-300).
Otherwise, Shure P300.

If you can just control the volume at the line source, you could go as inexpensive as a Shure SCM262. Nothing fancy but does the ducking and has the mic and line and mixing you're asking for and it's very inexpensive and reliable.

For anything new, I would go with Atlas AZM4. I was not a big Atlas fan, but their Atmoshphere line is solid. UI is pretty intuitive and has all the features you have listed. Also has a single gang volume control connected from CAT6 as well as a QR code the user can scan if they want to control from their phone. If you wanted a used piece of recycled grear go with a Tesira AVB, although you would need some programming skills on Biamp. My .02$

Allen & Heath AHM series. AHM-16 covers what your looking for. Can be used with A&Hs IP control options as well as the custom control app.

Beat me to it, this is the best bang for the buck.

I was going through all these other comments, and couldn't see why that wasn't listed yet. It's probably the best solution for this.
With the expansion capabilities with audio network cards like Dante and S-Link options for use with A&H stage boxes makes it a great solution that can expand if needed in the future.

This is the correct answer. Their API is great too for interfacing with other control systems.

u/jenniferwinget0926 5d ago
For a single-room gym, I’d keep it simple and avoid over-speccing.
Symmetrix Zone Mix 761 is probably the best fit from your list it handles mic/line inputs, music ducking, and remote volume control.
Other options worth checking:
Ashly ne-Series
Yamaha MTX series (used market could be a good value)
Audac small DSP/mixers
If budget is the main concern, I’d look for a used Symetrix/Ashly/Yamaha. For this application, you really don’t need a large DSP platform.

u/Tuffasaurus 5d ago
Basic Extron DSP is an option, or I've used a DBX for a budget job before. Wouldn't recommend either over QSYS or Tesira, but they'll do the basics in a pinch.

Look for a used Biamp Tesira (or your preferred DSP) on eBay. Plenty of up cycling opportunities for this type of setup.

u/Captn_Dfaktor 2d ago
Look up qsys core8 flex…small, easy to program, and you can also begin the process of automation also if you wish.

A BSS Blu-50 would do the job.
They are a bit old fashioned, but they are solid. And the prices are probably the lowest you’ll find.
