Digital Mixer for RTX 5090 Livestream: X32 vs CQ18T

Your RTX 5090 handles the visuals, but what about the sound? We compare the best digital mixers under $1,200 for a complex acoustic band livestream.

You have built the ultimate streaming PC with an RTX 5090 and a 24-core processor. It crushes OBS rendering and PTZ camera control. But if you are still relying on a daisy-chained stack of Focusrite interfaces for audio, you are bottlenecking your production.

For a small acoustic band requiring discrete multitrack recording, 6 independent in-ear monitor (IEM) mixes, and a broadcast-ready stream feed, a dedicated digital mixer is mandatory.

We evaluated three top contenders under the $1,200 budget: the Behringer X32 Rack, Allen & Heath CQ18T, and Soundcraft Ui24R. Here is the verdict for your setup.

The Scenario: “The Acoustic 8”

The challenge is to mix a specific band configuration:

  • Inputs: 2 Acoustic Guitars, 1 Mic’d Cajon, 2 Lead Vocals, 3 Backup Vocals (All on SM57s).

  • Outputs: 6 separate IEM mixes (stereo or mono) + Main PA + Livestream Feed.

  • Workflow: Must record 12+ discrete channels into Pro Tools while simultaneously sending a processed stereo mix to OBS.

Contender 1: Behringer X32 Rack (The Routing King)

Despite its age, the X32 Rack remains the industry standard for a reason.

  • The Killer Feature: 32×32 USB Interface. This is crucial for your workflow. You can send raw ISO tracks to Pro Tools for recording, while simultaneously routing a completely separate “Bus” mix to OBS for the stream.

  • Expansion: It supports AES50, meaning if you add that stereo keyboard later, you can easily expand inputs via a stage box.

  • Plugin Power: The X32’s routing flexibility allows you to insert third-party plugins (via Waves SuperRack Performer) into your live chain with low latency—something the newer, simpler mixers struggle to do.

Contender 2: Allen & Heath CQ18T (The Modern Touch)

The CQ18T is the new kid on the block, featuring a touchscreen and “smart” features.

  • Pros: It sounds incredible (96kHz audio) and is very easy to use. The “Gain Assistant” is great for quick setups.

  • Cons: It is designed for simplicity. While it can do multitrack USB, the routing is rigid. Creating a complex “Stream Mix” with different compression settings than your “Front of House” mix is more cumbersome than on the X32.

Contender 3: Soundcraft Ui24R (The Web Warrior)

  • Pros: The HTML5-based control is fantastic (no app installation needed). It has excellent preamps and built-in amp modeling for guitars.

  • Cons: Like the CQ18T, its insert point flexibility is limited compared to the X32.

The Verdict: Why the X32 Rack Wins

For a user who is already technical enough to run an RTX 5090 and Pro Tools, the Behringer X32 Rack is the only choice that fits all requirements.

  1. Independent Stream Mix: You can dedicate a stereo Bus pair solely for the livestream, applying heavy compression (broadcast style) without squashing the sound for the audience in the room.

  2. Monitor Mixes: With 8 XLR outputs + 6 Aux outputs, you can easily generate 6 independent mono IEM mixes without needing external gear.

  3. Future Proofing: When your band grows, the X32 ecosystem grows with you. The CQ18T hits a hard ceiling.

Recommendation: Pair the X32 Rack with Mixing Station (app) on a tablet for control, and let your RTX 5090 PC handle the USB audio processing via OBS.

  1. This setup is not volunteer-friendly. You should reconsider your priorities. You can have a system that is either affordable and fully functional, or one that is easy for volunteers to use.

  2. Record at least 12 individual channels into a DAW for isolated tracks to post-mix in Pro Tools. How do you see these as different tasks? They seem the same to me. Are you trying to record to two separate computers, or is this about using inserts?

    For the livestream, the key question is whether the same laptop running the DAW and recording the multitrack will also handle the stream. If not, you can send a post-fader aux mix out through one of the 1/4″ aux outputs.

    I generally prefer not to combine the multitrack recording with other audio routing, like the livestream feed, but it is possible using the user routing groups. It will require some time to configure.

    I’ve multitracked 18 channels and run lighting software simultaneously on an older T480 laptop (i5, 16GB RAM) for my band without issues. Attempting to route break music from the laptop back into the X32 was tricky, as some applications don’t handle the additional I/O well. OBS should be easier than Spotify or Google Music was, since it can use ASIO drivers.

    Personally, I would use a separate computer for the recording, SuperRack, or LiveProfessor, and a different laptop for OBS. This provides a backup if one computer fails. The livestream quality can be compromised if needed, but the in-person experience should be prioritized.

    I am a fan of the X32 Rack, though I own two, so I am biased.

  3. The X32 Rack or a used QU-16/24 would be a better fit for your budget of around $1,200. While a setup with a main mix and six monitor/IEM mixes is common, your requirement for a dedicated livestream mix rules out simpler mixers like the CQ18T or XR18, as they typically only offer the main mix plus six aux sends.

    1. The use of emojis in the paragraphs is what gave it away for me.

      Edit: The same post in the livesound subreddit explicitly stated that “AI said this would be good.”
