Bose L1 Model 1S Power Stand Amp Module

Base power unit for the Bose L1 Model 1S portable PA system


The Bose L1 Model 1S Power Stand, much like the rest of the L1 range, is a super-portable power amp and the base for your 1S portable PA system. With a lightweight design and featuring 4 retractable legs, the unit itself is very easy to transport. Also boasting a robust enclosure, the Bose 1S Power Stand can handle the stresses of touring - no problem!

The unit features integrated power amplifiers that provide clean, precise amplification for the system. Including a ToneMatch port, this is used to connect the ToneMatch audio engine that gives you overall control of the S1 PA system.

It doesn't end there though, as the S1 Power Stand also features an analogue input, trim control and signal/clip LED for line-level analog input via 1/4" TRS phone cable. This can be used for instruments, DJ mixers, MP3 players, computers or DVD players.

The stand also boasts a 'Bass Module Out' to connect with one or two B1 bass modules or one B2 bass module. The L1 system automatically adjusts equalisation appropriately when bass modules are connected, meaning that you don't have to worry about tweaking your setup.
