The SPRO 1200 power amplifier is professionally designed for both installed sound application and portable PA. It is rugged and offer the best value at an affordable price.

The SPRO 1200 is designed with Class H topology and Switching Mode Power Supply (SMPS), therefore the weight is ultra-light. It provides selectable stereo mode, parallel mono mode and bridged mono mode in variable ways of using the unit, and it has been thoroughly tested and designed to mount into a standard 19"rack.


The SPRO 1200 model is equipped with selectable input and output terminals that make them suitable for professional sound application: XLR and 1/4" TRS input terminals with binding post and Speakon output terminals, which accept balanced and unbalanced connections. Use these connections to connect the output signals from a mixer, a crossover or an EQ to your SPRO 1200 amplifier. And there are extra XLR output connectors for signals easily passing through to multi-amps setups. Binding post and Speakon output connections for dual channels or bridged mono channel. Setting to subwoofer will only allow frequency output at 20Hz to 200Hz to play.

Protection circuits include short circuit protection and detent gain controls. The circuit breaker is designed to protect the amplifier and your speakers in the event of an AC overload. Detent gain controls for easily repeatable settings.  

Built-in limiter allows signals below a specified input power to pass unaffected while attenuating the peaks of stronger signals that exceed this input power.

Indicators clearly showed the status of the protection systems and other parameters: each channel is designed with separate PROTECT indicator indicates protection circuit activation; SIGNAL, level at -20dB, -10dB, and CLIP indicators; PARALLEL, STEREO, and BRIDGE indicators show unit's amp mode status. Continuously dual 2-speed fans efficiently prevent overheating and maintain high stability.
