I received the 10-channel model and quickly got into the single-knob compressors available on channels 1 and 2. They were perfect for instant control when set up to about mid-way on the knob. They have a reasonably fast attack time to bring sudden unexpected peaks under control quickly with a minimum of fuss: it's basically grab and go.

Also a winner for me is the GigFX™ effects engine for quickly finding a pre-set digital effect. I used it on lead vocals, drums, keyboards and guitars as well entire track mixes that needed a touch of room liveliness. I thought the #24 Slap/Reverb and the #13 Doubler were especially good effects.

I also tried the Onyx Mic Preamps and they are quiet and have enough gain (up to 60dB) for most modern microphones and applications. I believe that with this Mackie ProFXv3 10-channel mixer tucked under your arm, you could walk into and be ready for most any gig.

The 2x4 USB I/O means you can have two stereo mixes on your computer sent to the ProFXv3 mixer at the same time. You could have a full track mix and another mix (say drums or vocals only) when you might need extra control over for monitoring. This works great for recording vocals alongside a pre-recorded track--a popular hip-hop production methodology.

The Mackie ProFXv3 Series Effects Mixers are built super tough with a steel chassis and there are optional protective dust covers available.

Prices range from $149.99 MSRP for the Mackie ProFXv3 6-channel model up to $899.99 MSRP for the Mackie Pro FXv3 30-channel console. As tested, the Mackie ProFXv3 Series Effects Mixer 10-channel version sells for $229.99 MSRP.
