Biamp MixPak 7 Plus+ Rackmount Powered Mixer, Road Case - Used
Biamp built the MixPak Plus+ series out of their Portland, Oregon facility as a commercial-grade all-in-one solution for venues, houses of worship, rehearsal spaces, and touring rigs that needed reliable, flexible sound reinforcement in a single rackmount package. The idea was simple and the execution was serious: a multi-channel mixer, a 300 watt power amplifier, and a 9-band graphic equalizer in one unit, built to a standard that could handle real-world use without complaint. The MixPak 7 Plus+ delivers on all of it. Standard input channels each offer high and low impedance inputs, two-band EQ, main mix level, monitor send, and effects send. The two Plus+ channels are optimized for keyboards and electronic instruments. The 9-band graphic EQ provides 15dB of cut and boost at one-octave spacing for full system frequency control, and the built-in multi-spring reverb covers basic effects needs without requiring an outboard unit. The 300 watt amplifier section includes Biamp's Auto-Limit circuit — a fast-attack, quick-release peak limiter that protects the amp while maintaining full power output. Eight-segment LED metering keeps you informed on output level at a glance. Full patching capabilities on the rear panel let you run the mixer, EQ, and power amp independently or in combination, which gives this unit a flexibility that simple all-in-ones typically lack.
This one has been tested and is working cleanly throughout — all channels functioning, EQ responding correctly, reverb working, amp section strong. Well loved and ready for the road, which the road case it comes in makes literal. This is a working piece of pro audio gear in working condition.
Condition is Very Good with signs of use consistent with a unit that has lived in professional environments. Check the photos for cosmetic specifics. Comes in a road case.
