A LANC input, also known as a LANC jack or port, is a type of control interface found on certain video equipment.
LANC stands for Local Application Control Bus System. LANC control jacks are used for controlling the tape transport of video equipment and connected peripherals. This jack has the same function as a jack labeled CONTROL L or REMOTE.
What Does a LANC Input Do?
Primarily, a LANC input allows external devices or controllers to manage functions related to tape operation on a video recorder or camera. This includes commands like:
- Start/Stop recording
- Playback
- Fast Forward
- Rewind
- Pause
By using a LANC connection, professional video setups or remote control units can precisely control the operation of cameras and recorders without needing physical access to the device's built-in controls.
Alternative Names
As mentioned in the reference, you might encounter LANC inputs labeled differently depending on the manufacturer or specific model. Common alternative names for a LANC jack include:
- CONTROL L
- REMOTE
These names all refer to the same type of control interface based on the LANC protocol.
Where Was LANC Used?
LANC was widely used on consumer and professional video cameras and recorders, particularly those using tape formats like Video8, Hi8, Digital8, MiniDV, and some early digital camcorders with tape-based recording. While less common on modern file-based digital cameras, the protocol's principles of external control are still relevant in various professional video production workflows.
Key Characteristics of LANC
| Feature | Description |
|---|---|
| Purpose | Remote control of video equipment (tape transport, recording, playback) |
| Full Name | Local Application Control Bus System |
| Also Known As | CONTROL L, REMOTE |
| Connectivity | Typically a small, multi-pin connector (often 2.5mm mini-jack size, but with specific pinout) |
This dedicated port streamlined operations for tasks like editing (allowing precise transport control from an editing deck or computer interface) or remote camera operation (for instance, on a jib or crane).
LANC technology provided a simple yet effective way to integrate different pieces of video equipment and controllers, enhancing flexibility in video production.
