The WP series of wall plates are US-made brushed aluminum plates fitted with Neutrik® XLR connectors firmly machine-riveted into place, and are designed to fit standard US single-gang electrical boxes. Note that the XLR gender used in intercom is the reverse of that normally used in audio applications to avoid the voltage present on an intercom circuit from being accidentally applied to a microphone.
Information about our specialty cables is also included is this Technical Information sheet.
The TR1 is the smallest, lightest package we could design while making it possible to manipulate in a hurry, or in the dark. On the front panel are inputs for both ¼” and 3.5mm plugs, and a rotary volume control which can be turned down, but not all the way off. Internal jumpers allow the technician to set the lowest level preferred. The rear panel features a green LED indicating that the unit is connected to the system and is receiving the required 18~30 VDC from the power supply. A red LED flashes indicating that audio traffic is being received. An external, recessed switch allows the technician to choose between single and two channel operation.
Connection to the IFB circuit is made using the TR1’s removable cables that terminate either in a 3-pin female or a 3-pin male XLR or, provided with a cable which Ys, both are possible. A variety of lengths are available on request. Connection to the TR1 is via a 3-pin mini XLR. The cable used is steel reinforced..
The SB1 will split one cable run into four, or split one cable run into two and add a new isolated circuit with two connectors. The ‘Isolate” switch changes the function.
Though beltpacks, etc. often let you run the circuit into one XLR and then loop onwards to the next station from a second XLR, often it is awkward and inconvenient to have two cables trailing off your hip. Running a circuit to a position near several beltpacks and into an SB1 will allow you to run only one cable to each of 2, 3, or 4 beltpacks. Not only is this more convenient but often requires a great deal less cable.
Where you have too few outlets at the back of a Master Station or Power Supply, plugging in an SB1 turns one into four.
The SB1 is tough and can tolerate lying around on the floor as well as the rigors of loading in and out.
