LS-750/850 SERIES

SPECIFICATIONLINE UPAPPEARANCEDOWNLOAD

An optical fiber transmission has an attractive function both for HD＆4K

What specifications are ideally requested for today’s high-end optical fiber system?
Here is the answer. After deep investigation of advanced HD production and the 4K production, LS-750 & LS-850 have been developed with the most innovative features.
This flagship optical fiber transmission system can transmit 4K pictures (either 3840/60P or 4096/60P) coming from 4 x 3G-SDI.
And also one more 3G/HD-SDI signal can be transmitted simultaneously which can be quite useful for the monitoring system integration.
Because LS-750/850 can transmit all of ancillary data and metadata on SDI standard, any type of 4K/HD/SD camera can be connected with the innovative system.
Even more is its amazing power supply function. There are three types depending on the application, up to 300W @ 12V + 100W @ 24V can be supplied. There is no need to worry about power supply in the field from drama / cinema production to live broadcast.

These five 3G / HD-SDI inputs can be operated and transmitted independently, so it is not only 4K, and for example, you can perform a remote work such as transmitting images from five HD cameras with just one LS-750. It has the ability to significantly reduce HD relay costs.

In addition, one return video signal (3G / HD-SDI, 1080 / 60P or 1080 / 60i signal), camera remote control signal, intercom audio, genlock signal, etc. can be used simultaneously with one optical fiber cable (SMPTE / Alive cable). ) Can be transmitted, and power can be supplied to the attached camera.
One of remarkable feature is IP communication capability, which is getting more important to control some of advanced accessories.
By having variety and flexible interfaces, LS-750 / 850 can work not only with current cameras, but should work also with the future cameras so that this system can be usable for longer years to prevent vain investment.

Powerful Power Supply Capability via a SMPTE Hybrid Fiber Cable

All signals between LS-750 camera adaptor and LS-850 base station can be transmitted in a SMPTE Hybrid Fiber cable with power supply for the camera and accessories.
The possible power supply capability is Max.60W for LS-750/850, but it can be up to 300W for LS-750GT/850GT high power model.
Furthermore, high power model LS-750GTS / 850GTS can supply about 200W, and extra high power model LS-750GT / 850GT can supply about 300W. (Please consult us because the power supply varies depending on the cable extension distance.)
(Note) The standard type of optical fiber connector is Tajimi type. Please specify when ordering if you want LEMO type. If not specified, standard Tajimi type is delivered. If the specifications are changed after delivery, it will be charged.

LS-750 (“4K Plus X” optical fiber transmission camera adaptor)

With a V mount, it is a multifunctional and powerful optical fiber transmission camera adaptor that cannot be imagined from the compact housing that can be easily mounted on the HDS-300S and other cameras.
One of the notable features of the LS-750 is that all 5 LS-750 3G / HD-SDI inputs are equipped with active through outputs. This makes it possible to perform optical fiber transmission of the same image while recording the camera image at hand with a local recorder connected to the camera adapter, and to ensure backup recording for important recordings.
By connecting the return video (3G or HD) output from the LS-750 to the PROTECH Ultra-OLED viewfinder HDF-EL800, you can shoot the camera while switching between the camera video and the return video. In addition, since it can have full-scale intercom and tally functions, it is possible to construct a practical relay camera system in combination with any camera / camcorder.

LS-850 (“4K Plus X” optical fiber transmission base station)

Base station for LS-750 series. Equipped with 5 3G-SDI outputs that can handle 4K live with plenty of room, return, tally, intercom, genlock, and camera remote terminal, even when power is supplied to the camera adaptor, the cable can be extended up to 2km.

AC / DC drive possible

Considering field operation as well as AC drive, both LS-750 and LS-850 can be driven by battery (12V type / 14.4V type). The low power consumption design enables long-time operation and allows use in an environment where AC cannot be obtained.

Linked monitor function: Real-time display of system connection status.

By connecting a camera remote controller such as Sony / Panasonic, or a lens controller such as C-motion, two serial communication is possible between the camera adaptor and the base station.

This makes it possible to remotely control the lens iris, camera white balance, gain, gamma, black level, and details from the base station. (There are differences in operation items and stability depending on the camera and controller to be connected. Also, LANC control can only be transmitted in a mode that can be used by connecting the remote control directly to the camera. Please contact us for details.)

IP network communication function

Since the LS-750 / LS-850 is equipped with an IP network (Ethernet) communication function up to 100Mbps, it is possible to remotely control camera peripherals that operate under network control, which has become the mainstream in recent years.

2W / 4W intercom installed

The 2W intercom is equipped with two lines, an engineer line and a producer line, as well as a clear cam line.
In addition, broadcasting intercom such as 4W system can be connected as it is. (Excluding some models)
