The Transmitter has 2 omni antennas, signal interfaces are:
1x 3G/HD/SD-SDI input
1x HDMI 1.3 input
(If both SDI and HDMI are connected, the system transmits SDI as priority.)
1x 6-17V DC input
The Panel Receiver adopts 14dBi high Gain Panel Antenna and build-in wireless receiver design, to set up by lighting tripod.
The Panel Receiver interfaces are:
1x 3G/HD/SD-SDI output
1x 7-36V 4pin LEMO DC input
In Line-of-Sight, S-4904P supports non-compressed 3G/HD/SD-SDI and HDMI 1000 meters (3300 feet) transmission, with less than 1 millisecond latency.
Embedded Audio Transmission
S-4904P supports SDI and HDMI embedded audio (CH1&2) transmission.
S-4904P wireless system works at 5.1-5.9GHz License-free frequency. The frequency bands are user configurable and support 3-4 pairs wireless channels to work together in one location.
The wireless output power is less than 63mW, which will not do harm to human bodies.
Users can set several Receivers at the same frequency point as the Transmitter, to enable 1 Transmitter to multi Receivers multicast mode.
Power Supply and Set-up
