The Behringer S16 is the budget AES50 stage box paired with X32-series consoles. Sixteen Midas-designed preamps at the stage and eight XLR returns, all multiplexed onto one shielded Cat5e — two AES50 ports allow redundancy or daisy-chaining to a second S16 for 32 inputs from a single console port. A mainstay of IEM rigs where the stage-to-rack run would otherwise need a 16-pair analog snake.

Power draw sits at 22 watts nominal and tops at 30, so it's easy on your rack's power budget. The 184mm depth and 4.8kg weight are honest stage-rack numbers — not ultralight, but it won't punish a shallow utility rack either.

If you're running an X32, X32 Rack, or X32 Compact as your console core, the S16 is the obvious, lowest-friction stage boxThe I/O endpoint on stage: mics plug in there and one digital line (AES50, Dante) carries everything to the console. The snake, digitized. choice — the AES50The Behringer/Midas console-to-stage-box link: 48 channels each way over one shielded Cat5e cable, with near-zero latency. integration is native and setup is minimal. It is not an open-protocol DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. or AVBAudio Video Bridging — open network audio (MOTU, PreSonus) where the switch reserves bandwidth so streams can’t glitch.

Sixteen Midas-designed preamps at the stage and eight XLR returns, all multiplexed onto one shielded Cat5e — two AES50 ports allow redundancy or daisy-chaining to a second S16 for 32 inputs from a single console port. A mainstay of IEM rigs where the stage-to-rack run would otherwise need a 16-pair analog snake.View gear →
S32The Behringer S32 brings 32 Midas-designed preamps to the stage and carries every channel — plus 16 returns — back to the console on a single AES50 link over shielded Cat5e. Two AES50 ports for primary + redundant operation. The go-to mate for X32 Rack and Wing Rack when the rig needs full-band mic channels without a pair of 24-pair analog snakes coiled in the truck.View gear →
SD16The Behringer SD16 is a budget-friendly 16-input, 8-output AES50 stage box compatible with Behringer X32 and Midas M32 consoles. Daisy-chains to additional SD16s for larger channel counts. The default pickup when a budget X32 / M32R rig needs more inputs at the stage.View gear →
SD8The Behringer SD8 puts eight remote-controlled Midas-designed preamps and eight returns on an AES50 run, in a compact chassis that lives on stage or in a drop rack. For X32/WING rigs it is the cheapest way to add an eight-channel drop without a full S16. Chains with other SD/S boxes over the second AES50 port.View gear →
