An Extension Speaker Designed for the RoadMan 102 Ecosystem
The Roadman 102 SL is designed as a "slave" speaker intended to complement a RoadMan 102 sound system. Its role is clear: to increase coverage and sound presence by adding an additional point of diffusion, while remaining consistent with the system architecture thanks to the Audio-Link connection principle. This product line logic allows an installation to evolve according to needs, from a simple setup to multi-speaker cascading diffusion.
Intended Uses and Users
This slave active speaker is aimed at users who already have (or plan to have) a RoadMan 102 system and wish to quickly extend their sound coverage: speeches, hosting, classes, meetings, presentations, small stages, community events, or temporary installations. The inclusion of rechargeable batteries makes it a relevant ally when access to a power outlet is limited, while maintaining a familiar setup for technical teams and presenters.
Thanks to its portable format and speaker stand mount, it easily integrates into a "mobile" configuration: you can position it where coverage is lacking (back of the room, side zones, proximity reinforcement), then move and store it without wasting time.
Audio-Link Connectivity, Class D Amplification, and Mobility: Daily Efficiency
Audio-Link Cascading via XLR
The Roadman 102 SL offers an Audio-Link input and output in XLR format (female XLR input, male XLR output). This approach ensures clean and reliable cascading to multiply diffusion points. The Audio-Link Slave volume control allows adjusting the level of this speaker within the system to balance sound coverage according to distance and acoustics.
Class D Amplification and Custom Speakers
The Class D amplification is designed to provide good efficiency, low heat generation, and integration suited for a portable speaker. The speaker configuration combines a 10-inch (254 mm) woofer/midrange and a 1-inch (25.4 mm) tweeter, both with ferrite magnets and "custom" components specified by the manufacturer. The result aims for clear voice diffusion and sufficient dynamics for accompanying musical content.
Power Supply: Mains or Batteries, with Charge Monitoring
Supplied with 2 rechargeable batteries (12 V / 4.5 Ah) and a power adapter, the speaker can be used in mobile or plugged-in configurations. A charge/battery indicator helps anticipate remaining autonomy and manage sessions. Short-circuit protection contributes to reliability during regular use.
