Behringer SD16 Review

Build and Design
Audio Quality and Preamps
- Equipped with 16 Midas-designed, remote-controllable mic preamps, delivering clean, audiophile-quality sound with low noise and ample headroom.
- Supports +48V phantom power, fully programmable via the connected mixer, ensuring flexibility for various mics and instruments.
- Users praise the preamps for their clarity and warmth, often comparing them favorably to the X32’s preamps, though some note they lack the depth of higher-end Midas PRO series.
- No noticeable latency or jitter thanks to Klark Teknik’s SuperMAC technology over AES50, ensuring reliable audio transmission.
I/O and Connectivity
- 16 XLR/jack combo inputs and 8 servo-balanced XLR outputs, ideal for stage setups needing a mix of mic and instrument inputs.
- AES50 networking (Klark Teknik SuperMAC) supports up to 100m runs over a single CAT5e cable, replacing bulky analog snakes with minimal setup.
- Integrated 4-port Ultranet hub for direct connection to Behringer P16-M personal monitor mixers, streamlining IEM setups without additional hardware.
- USB Type-B port for firmware updates via PC, though some users report frustration with Windows-only firmware updates (no Mac support).
- Limitation: Output assignment (e.g., 1-8, 9-16) is set via a side switch, which can be hard to access when racked, and only 8 outputs may not suffice for larger monitor setups.
Performance and Features
- Plug-and-play simplicity with X32/WING mixers; users report seamless integration, often requiring minimal configuration beyond routing on the mixer.
- AES50 allows cascading multiple stage boxes (e.g., SD16 with S16 or S32), providing flexibility for larger setups with up to 48 channels per port.
- Outputs are assignable in blocks (e.g., 1-8, 9-16), but lack the S16’s onboard control options like headphone monitoring or VU meters, making it less versatile for standalone use.
- Users appreciate the combo inputs for direct 1/4″ connections, especially for keyboards or guitars, reducing setup time in live scenarios.
- Drawback: Some report AES50 port failures after 1-2 years, though this isn’t widespread; firmware updates (e.g., to v2.2) can resolve compatibility issues with older X32 setups.
Value and Reliability
- Priced around $585, offering strong value for a 16-channel digital snake with Midas preamps and Ultranet integration, undercutting competitors like the Midas DL16 ($698).
- Users frequently highlight its cost-effectiveness, with many churches and small venues calling it a “game-changer” for replacing analog snakes.
- Warranty is 1 year standard, extendable to 3 years if registered within 90 days of purchase—a point of contention for some who missed the registration window.
- Mixed reliability feedback: most units perform flawlessly for years, but some users report issues like AES50 port failures or firmware update challenges.
User Experience

Summary

The Behringer SD16 is a cost-effective, reliable digital stage box that excels in simplifying audio setups for live sound and studio applications. Its 16 Midas-designed preamps, combo inputs, and Ultranet integration make it a versatile companion for X32 or WING mixers, particularly for small to mid-sized venues or churches. The AES50 networking ensures ultra-low latency over long cable runs, and the compact design is a boon for portability. However, the side-mounted ports can complicate racking, and the lack of onboard controls limits standalone use compared to the S16. Despite minor reliability concerns with AES50 ports, the SD16 offers excellent value, earning high praise for its performance and ease of use in budget-conscious setups.
