ALS-216 Personal Trainer

Equestrian Training • Rider-Instructor Audio Link


Experience the advantages of crystal clear sound with the ALS-216 Personal Trainer. Used by top equestrian trainers and riders all over, this system allows trainers to communicate with riders over long distances with perfect speech clarity. Simple to use, the trainer wears the M-216 personal transmitter and lapel microphone, and the rider wears the PR-216 personal receiver and earphone. The rider can be as far away as 300 feet and not miss a single word. What’s more, with additional receivers, multiple reders can monitor the trainer at the same time. Plus, its rugged construction ensures long-lasting durability in even the most demanding environments.

1 x M-216 Option 1 Transmitter (Includes mic mute switch)
1 x CM-183 RT Omni-directional Lapel Microphone
1 x PR-216 Personal Receiver
1 x MDR-J10 Left & Right Mono Headphone Set

This unique receiver can be mounted on a powered speaker to create a portable wireless PA system and can be used simultaneously with the ALS-216 system. Perfect for clinics, shows, and special events, both the rider and the audience can hear the trainer without the need for a second wireless microphone system.
