LZSIG's streaming gear lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How many instruments can I plug into the LZSIG mini mixer at once?

Four. It is a 4-in, 1-out line mixer, so it can combine four sources, such as an electronic drum kit, keyboard, guitar and computer, into a single output.

Do I need adapters for 1/4 inch and 3.5mm cables?

No. The jacks accept both 6.35mm (1/4") and 3.5mm (1/8") plugs in TRS or TS form, so you can use instrument cables and headphone-style cables without adapters.

Does this mixer come with a power supply?

No. The mixer runs on 5V DC, and the power adapter is sold separately. LZSIG recommends a CE- or UL-certified supply for the best audio quality.

Can I output in mono instead of stereo?

Yes. A mono/stereo switch lets you choose between a summed mono mix and a stereo line mix to match your amp, PA or recording input.

How do I reduce hum or noise when using it?

The mixer has an MPS power management chip designed to remove ground noise, plus ROHM low-noise op-amps. For the cleanest signal, use a certified 5V DC supply and keep the unit away from other electronics.
