I've been using the four channel Mackie 402 VLZ4 as a recording mixer and on guitar meets DJ gigs, and it has performed exceptionally on both situations. The chassis is made of thick steel, connectors feel solid, knobs turn smoothly and everything is logically laid out. Good build quality all around.
Channels 1 and 2 are for microphone or line level input and have a high impedance switch, a low-cut switch and a two band EQ. You can configure these as a stereo pair with the pan button. Global switchable 48-volt phantom power is only fed to the XLR connectors, not the 6.3 mm jacks. The preamps sound lovely - tons of gain and very clear. Channels 3 and 4 are for stereo or mono line input. They get hard panned if both are connected. There are also tape in / outs that can be used for connecting to an audio interface. Tape in can optionally be routed to main out, which essentially makes it channels 5 and 6. Nice!
There is only one pair of balanced outputs available, which might be an issue for some. I use headphones for monitoring and mixing, so for me it's been fine. Also there are no variable pan knobs, mute switches or effect sends. Take a look at the eight channel 802 VLZ4 if you think you will miss these features.
This is a really good no-frills small format mixer. It's simple, well built and sounds great!
