Alto Professional has announced that MIXPACK and MIXPACK Express, two new portable PA systems, are now shipping. Their all-in-one designs include a central powered mixer with a storage compartment and two loudspeakers. These three components attach to one another to form one pod-like structure with wheels and a handle for easy transport. Loudspeaker cables are also included with both systems, as well as two speaker stands.

MIXPACK offers built-in Alesis DSP effects, six inputs, two Aux sends with stereo returns, RCA input/output, switchable phantom power, three-band EQ on each channel, headphone out, LED meters, 600 watts of power, and a 3-way loudspeaker with a 12-inch cone woofer, four 6.5-inch MF drivers and two 1-inch HF drivers.

MIXPACK Express provides 350 watts of power, up to six channels of audio, seven-band graphic EQ, two-band EQ on each channel, one Aux send/return, RCA input/output, Headphone output, LED meters and built-in effects.

"MIXPACK PA systems are perfect for anyone who wants a sleek, portable system." says Jay Schlabs, executive director of Alto Professional. "They combine everything you need: powerful sound, EQ, quick setup and break down, even built-in effects."

The Alto MIXPACK Pro is the most powerful in the MIXPACK line of portable powered PA systems. A 15" subwoofer and two 6.5" speakers get the sound pumping in seconds behind 1000 watts of pure Class AB power so you're never left wanting more. The satellites lock securely on the back side of MIXPACK Pro and the included handle and wheels make moving the whole rig no problem. Put simply, there has never been a more easy and powerful way to bring this much power to any location.

Alto MIXPACK Pro doesn't stop with professional amplification and speakers. An eight-channel mixer is included so you can connect everything from musical instruments to microphones to an iPod. Four simple screws can be removed allowing the mixer portion to be detached and conveniently placed into your audio rack so you don't have to bend over to make adjustments during a show. Maybe your band is music gigging or you are a live sound engineer or sound contractor looking for something you can set up quickly without sacrificing quality or power, Regardless of where the performance takes you, MIXPACK Pro is easy to set up with all the right connections.  Stands are included and tuck neatly within the cabinet for transport so you can get the sound where it needs to go without any hassle.

Once all your gear is connected to Alto MIXPACK Pro, you can go to work on fine tuning for the event space with MIXPACK Pro's built-in 24-bit digital effects and 7-band graphical EQ. Effects include Hall, Room Vocal & Plate Reverb, Mono & Stereo Delay (max Delay Time 650ms) Chorus, Flanger & Reverb Modulations, Stereo Delay Chorus Rev+Delay and Rev+Chorus combinations. 256 total effects spread across 16 types with 16 variations mean that you are always ready for any room and any performance. 

When you need to get in and out in a hurry with high-power, clarity and flexibility, MIXPACK Pro is the ultimate portable PA choice. Also available are the 600W MIXPACK and 350W Alto MIXPACK Express
