Bose Professional is debuting the S1 Pro multi-position PA system — an all-in-one PA, floor monitor, practice amplifier and primary music system. Designed for general PA use, the S1 Pro is 15 pounds (6.8 kilograms) and with dimensions of 13″ x 9.5″ x 11.2″ (330 x 241 x 286 millimeters), it easily fits in an airplane’s overhead compartment.

The S1 Pro is engineered to be used in four different positions to accommodate a wide range of applications — tilt-back, elevated, mounted on a speaker stand or placed on its side (as a floor monitor). Built-in sensors detect positional changes and trigger Auto EQ, which automatically recalibrates the system’s internal settings for each different placement/application, ensuring that users always sound their best with optimum sound in any position.

The S1 Pro comes with a three-channel mixer. Reverb and tone controls are featured on two channels with XLR / quarter-inch combo jacks and a third channel is for either 3.5 mm (1/8”) line-in or wireless Bluetooth connectivity. Additionally, a line-out jack offers easy expansion to other systems. 

Using the wireless channel, music can be played from a mobile device easily using Bluetooth streaming (great for pre-produced backing tracks or background music), while getting great sound quickly with integrated ToneMatch processing for microphones and instruments. Additionally, users can enjoy hours of play on-the-go with the S1 Pro’s optional rechargeable lithium-ion battery; a special setting and intelligent circuitry offer a choice between trickle charge or dedicated full-power charge.

The S1 Pro multi-position PA system is $599 (optional rechargeable lithium-ion battery is also available at $99). Here are all the specs.
