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/HDSDI, 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.
