Simply SMPTE Max 3-Box

Categories: , ,

The Simply SMPTE Max 3-Box system allows you to connect to the latest UHD cameras and remote heads over a long distance using a single rugged SMPTE 311M hybrid camera fibre or a pair of inexpensive single-mode LC fibres.

This greatly simplifies and speeds up rigging of a camera position, providing signal connectivity in both directions (video, audio, control and IP data).
If used as a complete system (base, mid and remote boxes), it also allows transmission of signals, 12v DC and up to 450w of mains power over a SMPTE cable as part of the link.

This was born of the need to simplify connecting up our cameras and remote heads in outside broadcast situations.
The Simply SMPTE 4K Max 3-Box will pass give channels of 3G HD-SDI, stereo audio, and Camera Corps audio control data from a camera position back to the base unit. It'll also send one channel of 3G HD-SDI, analogue Genlock and stereo audio back, and then in addition RS232, RS422 RS485 and two channels of GPIO and ethernet in both directions.

The remote unit has two 12v DC power outputs (6 amps total max) and can also supply up to 450w of isolated mains power out when used in conjunction with the mid-box as a full system.
With this range of signal compatibility, you can rig an entire camera position (with an operator or as a remote head) and get all of your signals down just one cable back to the base position.
