You need at least 8 to 12 inputs for a small group session; first, connect your primary microphones to the XLR 1/4 combo inputs to ensure every voice is captured.
PMXU128BT mixer functions as a 24-bit USB audio interface
This mixer functions as a USB audio interface, which allows it to send and receive digital audio signals to a computer for use in a DAW (Digital Audio Workstation), a software application used for recording and editing audio. The PMXU128BT captures signals at a 24-bit depth, providing sufficient information to process audio with a high dynamic range. Because it includes a USB soundcard, it acts as the bridge between your hardware and your recording software without requiring a separate external interface. We included this mixer in our comparison of studio mixers because it offers a high input count for its price point. For a small group, the 12-channel capacity is sufficient to run a podcast with 4 guests or connect a full studio rack of outboard gear at the easier end of the range. The device also provides +48V Phantom Power—the electricity needed to power condenser microphones—on its inputs.

What to Check Before Buying the PMXU128BT Mixer
Checking these specific technical details ensures your recording workflow remains stable during a live session.
- Confirm your computer recognizes the mixer as a Class Compliant USB device to avoid the need for proprietary drivers.
- Verify that your specific DAW supports the 24-bit resolution to maintain the high dynamic range provided by the hardware.
- Check if your specific recording software provides a low-latency path for real-time monitoring of the 12 inputs.
- Ensure your recording space allows for the 15 ft wireless range if you plan to use the Bluetooth streaming features.
Alternative Options for the PMXU128BT Mixer
The PMXU128BT Mixer is a multi-channel mixing console, which is a physical surface with knobs and sliders used to balance and route different audio signals. While this unit handles small groups well, you should look at alternatives if you need to mix a live band with a full drum kit, which typically requires 16 to 24 inputs. Buyers requiring high-density routing or more complex physical routing for large-scale touring may find that other professional-tier consoles provide the necessary expansion that a 12-channel limit cannot reach.
