The Digital Devices MAX SX8 is a tuner card with 8 HDTV tuners on a single card with PCIe connector.
The high density of the design and the choice to select the operating mode as well as Unicable®1 and JESS®2 support and only 7 watt power consumption makes the card ideal and flexible for DVB-S/S2/S2X applications.
The card can be used with Windows 7, 8, 10 and Linux operating systems.
The operating modes are “Quad” or “Unicable”.
Using the “Quad” mode the card can either be connected to an LNB or a 4x multi switch. It supports one satellite.
In Unicable mode it requires only one coax cable to support 8 tuners using Unicable®1. Using JESS®2 it can be connected to up to 32 tuners with just one coax cable.
1 Requires Unicable®/SCR/CENELEC En50494 compliant LNB or multi switch.
2 Requires Jess®/CENELEC En50607 compliant LNB or multiswitch.

4 Maximum DVB-S2/S2X LDPC bitrate is limited to 720 Mbit/s. This bitrate is defined as symbolrate * bits/symbol, i.e. 8PSK 30 Msymbols = 90 Mbit/s. The used bitrate is dynamically allocated by the driver. DVB-S channels don't contribute to the limit.
5 Single/dual demod usage.
