LEN L4KP01 PPDuo is a HD/3G & 4K/12G SDI compatible galvanic isolator that acts as a Port Protector & Doubler to protect sensitive ports from transient voltages when hot swapping cables. The PP Duo protects your camera from induced voltages in long cable runs and provides a second SDI port with HD, 3G & 4K/12G SDI compatibility.
In some circumstances, the latest generations of advanced 4K/12G cameras may sustain damage to their SDI circuitry when connecting their SDI outputs to a cable. These problems typically arise from stray transient voltages present in the cables, which "earth" through the camera output BNC when first connected, placing great stress on the camera's internal circuitry.
The Current Solution
To overcome these problems camera manufacturers have typically recommended to avoid using certain cable types and rigorously following a precise connect/disconnect sequence which typically includes attaching the power source to the accessory before attaching it to the BNC cable.
Failure to adhere to these instructions may result in substantial damage to an expensive camera plus all the substantial costs and inconvenience associated with an interrupted shoot. However, many videographers have found that following these instructions is sometimes impossible during a shoot - for example when it is necessary mid shoot to change accessory batteries, or a moments inattention when members of the crew unfamiliar with these requirements are involved.
The new LEN Solution
Our PPDuo Port Protector & Doubler galvanically Isolates the Camera from the cable, preventing transient voltages in the cable reaching the camera.
PPDuo Port Protector & Doubler additionally incorporates our well established and market leading Splitter technology to add a second SDI signal output.
The LEN PPDuo is a unique galvanic isolator (designed to protect the SDI port) and port doubler, specially developed to overcome problems when connecting or swapping cables on the latest generation of advanced 4K/12G cameras.
Using a PPDuo essentially removes the risk of problems associated with connecting or swapping of cables, including "hot" swapping. With its unique advanced design PPDuo not only reliably protects your camera but also provides a second SDI port. Connect PPDuo to your camera SDI port and you then have two protected SDI output ports, each capable of outputting a high quality, clean 4K/12G signal. All LEN products are `passive' designs so that you do not need a power supply or to worry about reduced battery life. PPDuo simply plugs in to provide the protection you need, plus that extra port!
