TTU-3DX-L. The Battery-Operated TTU for Portability and When Cutting a Hole Isn’t Practical.

The TTU-3DX-L Series is a simple way to provide clear and high quality communication through glass or any barriers of any kind. This battery-operated unit allows for these units to be moved to various locations. It’s perfect when portability is a concern.

TTU-3DX-L Series is the best choice when it’s impractical to cut a hole through an isolation barrier. The prism shaped units are mounted on a countertop on both sides of the barrier and allow hands-free, clear communication.

The TTU-3DX-L is the most popular countertop voice communication system for security and isolation booths (shown with standard 18” gooseneck microphone)

Installation

The TTU-3DX-L comes ready to operate. The prism units are quickly and easily mounted on the counter-top on opposite sides of the barrier. The unit can be positioned against the barrier or any location convenient for the user. It comes with a power supply with 100-240 VAC input and 15 VDC, 1A output.

A Note on Part Numbers

The TTU-3DX-L has a number of options. Adding options to a unit modifies the part number. For example, the standard gooseneck microphone length is 18” but we offer a 10” and 24” option. A TTU-3DX-L with a 10” microphone would be part number "TTU-3DX-L-10.” The options above can be combined to meet your needs. For example a TTU-3DX-L with Wireless, Push To Talk, Noise Cancelling, ADA Compliance, and a 10” microphone would be “TTU-3DX-L-W-PTT-NC-ADA-10.” Note that the ADA Compliant Option includes a Monitoring and Recording Option so the two options can not be combined.
