How we ranked these audio mixers

Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Mixer channels / decks weight 3
Mic preamps weight 2

Buying advice: passive audio mixer

Count the channels you mix at once

Channels decide how many sources reach one output. The Rockville mixer takes 6 channels, the mickXer takes 5, the Cubilux mixer and the ART mixer take 4 each, and the Rolls mixer takes 4. Count your sources first, then pick a mixer with at least that many channels.

Check the connector type on each channel

A mixer only helps if your gear plugs into it. The Rockville mixer takes XLR and 1/4 inch connections, the mickXer takes 3.5mm connections, the Cubilux mixer takes 3.5mm connections, the ART mixer takes 1/4 inch connections, and the Rolls mixer takes RCA connections. Match the connector to your sources before buying.

Decide whether you need power or not

Passive mixers run without a power supply, while powered mixers add features that need power. The ART mixer uses a passive design with no power supply, and the mickXer and Rolls mixers are also passive. The Rockville mixer is the powered option here, with a USB interface, Bluetooth, and DSP effects that need power.

Frequently asked questions

What does passive mean in an audio mixer?

A passive mixer blends signals without a power supply or built-in amplification. The ART mixer uses a passive design with no power supply, and the mickXer mixer is also a passive mixer.

Can a passive mixer record straight to a computer?

If USB recording to a computer is the goal, a passive mixer alone does not cover it. The Rockville mixer is the pick here, with a built-in USB interface for computer recording.

How many sources can I mix at once?

The Rockville mixer takes 6 sources, the mickXer takes 5, and the Cubilux, ART, and Rolls mixers take 4 each. Count the sources you plan to mix, then choose a mixer with enough channels.

Do I need phantom power for a passive mixer?

Phantom power matters only for microphones that need it. The Rockville mixer supplies 48V phantom power on channels 1 and 2, so it is the pick when a mic needs that power.
