SapphireTX Camera Back User Manual
Introduction to the SapphireTX Transmitter
The SapphireTX camera-back transmitter, integrates a True 4K HEVC encoder with a
COFDM modulator creating a single, slimline package, suitable for camera-back mounting
whilst supporting twin SFP cages, thus allowing video input in formats of Single 3G-HDSI,
Quad 3G HD-SDI, 12G and Dual 6G (Arri format).
Back to back V Lock or Anton Bauer battery plates facilitate pass-through power whilst an
additional external power connector is provided at the base. Analogue stereo audio inputs
are supported as well as camera control and Tally interfaces.
SapphireTX is equipped with a high-quality, low- latency H.265 (H.264 is also available)
encoder capable of UHD and HD formats in 10bit 4:2:2 with automatic HDR support.
SapphireTX-D additionally supports legacy DTC low-latency HD H.264 encoding.
Up to 8 stereo pairs of audio in either MPEG-1 layer 1, or PCM format (4 stereo pairs in
AAC-LC) can be extracted and encoded by The SapphireTX whilst analogue audio inputs
with power are included for direct microphone connection.
Camera control and functionality is accessible through a single colour panel on the side or
using the web browser interface; BWS’ camera control being supported as standard with the
option of future upgrade to Bi-directional IP camera control.
