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.

Buying advice: 4 channel powered mixer

Check whether the mixer powers speakers

Built-in power decides this search. The Mackie is a desktop mixer with 2 Onyx mic preamps and phantom power, and it needs separate speakers or an amplifier. The two Rockvilles are powered mixer-amplifiers with 1800W peak output, so they drive passive speakers directly. If your speakers are passive, pick a powered mixer; if they are powered already, a desktop mixer is enough.

Count mic inputs, not just channels

All three picks give 4 channels, but mic inputs differ. The Mackie gives 2 mic inputs plus 4 line inputs, while the two Rockvilles give 4 XLR inputs each. If you run two mics and two line sources, the Mackie covers it; if you run four mics at once, pick a Rockville. Count the mics you plug in at once before you choose.

Compare effects and wireless options

Effects and wireless options separate the two Rockvilles. The RPM45BT adds Bluetooth streaming and a remote, while the RPM45 adds a fan cooling system for extended use. Both give echo, delay and reverb with per-channel bass, treble and volume controls, plus USB playback. The Mackie centers on Onyx preamps and phantom power. Pick the option set that matches your shows.

Frequently asked questions

Do I need a powered mixer for passive speakers?

Yes. A powered mixer-amplifier like the two Rockvilles drives passive speakers with its 1800W peak output. The Mackie is a desktop mixer, so it needs powered speakers or a separate amplifier. Match the mixer type to your speakers.

How many mics can I plug in at once?

The Mackie takes 2 mic inputs plus 4 line inputs, while each Rockville takes 4 XLR inputs. If you run four mics at once, pick a Rockville; if you run two mics with line sources, the Mackie covers it. Count your mics before ordering.

Which mixer has Bluetooth and a remote?

The Rockville RPM45BT has Bluetooth for wireless streaming from phones, tablets or laptops, and it comes with a remote. If wireless streaming matters to you, the RPM45BT is the pick with Bluetooth.

What effects do the Rockville mixers include?

Both Rockvilles give echo, delay and reverb with per-channel bass, treble and volume controls. The RPM45BT adds Bluetooth and a remote, and the RPM45 adds a fan cooling system for extended use. The Mackie centers on Onyx preamps and phantom power instead.
