An SM Wireless solution designed for reliability, from stage to installation
The analog SM Wireless systems continue the "SM series" spirit, which has become a professional reference thanks to a frequency response announced as very linear and proven reliability. Offered in complete sets (single, double, or rackable), the range aims to simplify choice according to usage: singing, hosting, speech, or specific configurations. This logic is reflected in the available packs (21 complete sets announced), including fitness-oriented versions, to provide a coherent and immediately operational system depending on the context.
A wireless headset microphone for singers, presenters, and hands-free performances
This "SM35 Headset" pack targets artists and speakers who want to maintain great freedom of movement while keeping stable pickup. The headset mic format is particularly relevant for hosting, stage singing, dynamic performances, or any situation where a handheld mic would be restrictive. The BLX1 bodypack transmitter is worn discreetly, while the rackable BLX4RE receiver naturally integrates into a mixing desk, flight rack, or fixed installation.
