This Eartec intercom kit provides you with everything you need to create a four-user full-duplex intercom system. It consists of the TCS Intercom Power Station, four Ultra Heavy-Duty Single-Ear Headsets, and four XLR cables.
The TCS Intercom Power Station can support up to six wired headsets in full-duplex mode with no beltpacks required for simultaneous hands-free talking between all users. It is housed in a rugged plastic console to withstand the rigors of use in the field. It is portable, but can also be permanently installed, and runs off the included 12V battery or on AC power.
The Ultra Heavy-Duty Single-Ear Headsets feature a unique septagonal earcup design that fully covers the ear for long-lasting comfort. They do not require beltpacks because volume and amplification are built into the headsets. Each headset is constructed from durable polycarbonate and has a flexible gooseneck mic boom.
Each cable has a 3-pin female XLR connector on one end and a 3-pin male XLR connector on the other to connect the headsets to the power station. The broadcast-grade cables are shielded to protect against signal interference and provide a grounded connection.
Note: This system can be expanded to six users by adding two more headsets. It can be further expanded to accommodate 12 users by adding a junction box per each additional user.
