The Behringer SD8 - I/O Stage Box with 8 Preamps is designed to connect the onstage talent to the Front of House (FOH) console. The stagebox provides 8 remote-controlled Midas-designed preamplifiers as well as eight servo-balanced analog XLR outputs. Two of the programmable inputs are compatible with Hi-Z sources so you can connect keyboards, acoustic, and bass guitars, etc. A USB port is included for fast and easy system updates via your PC.

An integrated 2-port Ultranet distribution hub is included for direct connection to the company's P16-M personal monitor mixers without the need for any additional hard wire. The compact unit features rugged protective bumpers and the option to be rack mounted using the included rack ears.

A single Cat 5e cable connects the stagebox, and up to three stageboxes can be cascaded together for a total of 24 inputs and 24 balanced outputs. An onboard Ultranet distribution hub provides power and 8 channels of audio to two of the company's Powerplay P16-M personal monitor mixers.
