2882 Overview
Figure 8.1: Mobile I/O 2882
What it is
Mobile I/O is a portable, high–quality, modular multi-format audio converter, interface, and processor for
professional audio applications. The 2882 model line is equipped with eight balanced analog inputs (4 on
XLR and 4 on 1/4" TRS), eight balanced analog outputs (1/4" TRS), fully configurable ADAT® / TOSLINK
optical I/O (with full auto-SMUX support), BNC wordclock in/out plus independent stereo AES/EBU and
S/PDIF Digital I/O ports (provided on the base-configuration EdgeBus card).
Host computer connection and box daisy-chaining are provided by two MHLink Gigabit Ethernet ports,
each of which support 128 channels of bidirectional audio at 192khz/32 bit data rate. A UAC2 class-com-
pliant USB-C connection is available as an alternative computer interface.
Analog inputs are capable of 24-bit/ 96kHz operation, although the analog outputs, digital i/o and internal
routing and processing paths support sample rates up to 192kHz.
What it has
• 20 simultaneous input channels and 20 simultaneous output channels (with the base S/PDIF•AES
EdgeBus card)
• 8 independent channels of mic-pre with switchable phantom power
• A/D and D/A conversion at 44.1, 48, 88.2, 96kHz Sampling Rates (D/A conversion operates at 176.4
and 192kHz. A/D conversion is not supported at 4x sample rates.)
• 24 bit 110 dB Dynamic Range A/D converters
• 24 bit 120 dB Dynamic Range D/A converters
• 8 Balanced Analog Inputs – 4 XLR, 4 TRS 1/4"
• 8 Balanced Analog Outputs – 8 TRS 1/4"
• Digital I/O, DSP processing, routing and formats conversion at 44.1, 48, 88.2, 96, 176.4 and 192kHz
Sampling Rates
• 8 channels of ADAT® Optical Input and Output (or 2 TOSLINK). Optical inputs auto-sense ADAT®
vs. TOSLINK format. Optical output format is user-selectable. SMUX is automatically implemented
to support high sample rates.
• MH EdgeBus programmable and pluggable audio expansion slot.
2882 base configuration includes the S/PDIF•AES Stereo Digital I/O EdgeBus card pre-installed
