RedNet PCIeR provides bi-directional Dante audio connectivity to Mac or Windows computers, and does so with full network redundancy. The card supports up to 128 channels of 24-bit bidirectional audio at 44.1, 48, 88.2 and 96 kHz sample rates, and 64 channels at 176.4 and 192 kHz. RedNet PCIeR mounts via a standard 4-lane PCI Express card slot. ASIO and Core Audio drivers are provided.

RedNet PCIeR uses the Dante audio-over-IP implementation, which can carry up to 512 bidirectional audio channels over a standard Gigabit (or higher) Ethernet link. Software is provided for the routing, controlling, and configuration of the card and attached interfaces, including remote control of reference level, selection of preferred master clock, and sample rate.

RedNet PCIeR includes fully redundant network access via dual rear panel RJ45 ports and will switch between primary and secondary networks automatically based on network availability.
