ULTRA COMPACT, MULTI-PURPOSE STAGE MONITOR
ST 12-SMA is a multi-purpose active loudspeaker, designed to be the everyday monitoring tool for rental companies and professional musicians. With its ultra compact design together with high output levels, ST 12-SMA is the answer to a wide variety of production requirements. It is particularly effective for small bands and personal use.

STAGE MONITOR
Use it as a stage monitor. The “FLAT” equalization mode is set for monitoring applications, when the system is placed on the floor.

LOUDSPEAKER
With an easy 90° rotation and a simple click on the FLAT/BOOST switch, the ST 12-SMA turns into a loudspeaker, with the equalization settings in “BOOST” mode.

LOGO PLATE
For the best visual impact RCF logo can be turned accordingly by 90°, thanks to a simple rotating movement.

TUNED FOR YOUR VOICE
ST Series provides a clear reproduction of midrange frequencies, with a specific focus on the voice

PERFECTLY FLAT RESPONSE CURVE
This turns into a maximum rejection to positive feedback between the stage monitor and the microphone, ensuring immunity from the Larsen effect (microphone-mixer-monitor chain) for an enhanced freedom of movement during live performances

SUPERIOR INTELLIGIBILITY
Voice and words are clearly recognizable even over distance.
