We - 5 people rock cover band - use this mixer to drive our PA in the rehearsal room and to power the stage monitors when gigging without a dedicated sound engineer. We are using all available mono channels and are very happy with the features - the power amp with Speakon outputs, two pre-fade monitor mixes, two FX engines (we use a fair sounding reverb for the four vocals and a bit of chorus for acoustic git), not-at-all noisy preamps, faders, and knobs, very low fan noise under load, fairly precise "meter bridge" (quite sufficient for live music).
In its Thon case, it does feel quite heavy, but can still be put on any cab or small table when on-stage.
After 2 years of use, we have one defective LED but it's pretty nearly perfect.
We have used its older sibling (PMP4000) for 8 years before it broke down. We didn't find anything better than the PMP6000 to meet our needs -
great price-performance ratio for live bands. We hope it lives 7 or more years, too!
