Key to SeaWorld's decision to purchase the Lectrosonics system was the introduction of the latest version of the company's waterproof miniature belt-pack transmitter, the MM400B. Previous versions of the MM400 did not feature a power switch and could only be turned off by removing the battery. The new MM400B features a waterproof power switch and allows that switch to be programmed as an audio mute.
This new feature of the Digital Hybrid Wireless transmitter combines 24-bit digital audio with an analog FM radio link to provide audio quality and extended operating range of the analog wireless systems. This allows the participating trainers and human performers to communicate instantly, without waiting through a power-up cycle. The 16 MM400B transmitters, four on each of the Venue system's available frequency blocks, are used with Countryman headset microphones. The Venue receivers are fed with Lectrosonics ALP700A LPDA weatherproof antennas.
Since this first system was installed in the San Diego SeaWorld Park, the other four SeaWorld locations have placed their orders for similar systems including the MM400B transmitters and Venue receivers.
Clyde and Seamore in Deep, Deep Trouble opened in mid-March, following major renovations, and is the eighth production to command the San Diego park's Sea Lion and Otter Stadium. The show submerges park guests two to eight times a day.
