A digital stage box moves microphone inputs and other audio connections from the stage to a compatible mixing console over a digital link, helping reduce long analog cable runs. The right choice depends on how many inputs and outputs you need, which connection system your console supports, and whether extras like personal monitoring connections or bundled cables will help your setup. These four options range from a 16-input Behringer unit to 32-input Behringer and Midas models.

Behringer SD16: A Smaller Stage Box with ULTRANET
The Behringer SD16 is the compact-capacity choice in this group, with 16 programmable Midas-designed mic preamps and eight analog XLR outputs. That gives you fewer connections than the 32-input models, but it can be a better fit when your stage plot does not need a full 32 inputs.
Its AES50 networking uses Klark Teknik SuperMAC technology, and the four-port ULTRANET hub is designed to connect compatible P16 personal monitoring mixers. The product description also lists connectivity for compatible Turbosound systems. These features make the SD16 worth considering when personal monitoring or other ULTRANET equipment is already part of your setup.
The main trade-off is straightforward: eight outputs and 16 inputs leave less room for expansion than the larger boxes here. Before choosing it, count your microphones, instrument feeds, and output needs, then confirm that your console and connected equipment support the required connection formats.
Pros:
- 16 programmable mic preamps in a more modest I/O configuration
- Eight analog servo-balanced XLR outputs
- Four-port ULTRANET hub for compatible personal monitoring mixers
- AES50 networking with SuperMAC capability

Midas DL32: Extensive I/O for Larger Live Setups
The Midas DL32 is a 32-input, 16-output stage box built around 32 Midas PRO microphone preamps with switchable 48 V phantom power. Its large input count can support a busy stage, while the 16 electronically balanced line-level outputs provide multiple routes back to stage equipment.
Dual AES50 SuperMAC ports allow compatible DL16 stage boxes to be cascaded without a merger or router, according to the product description. The DL32 also offers ULTRANET connectivity for personal monitoring and compatible Turbosound systems, plus ADAT interfaces. These connections can be helpful, but only if they match the rest of your audio system.
Compared with the SD16, the DL32 offers twice the input and output count and is better suited to larger productions. Its extensive I/O may be unnecessary for a small band or simple setup, so consider your actual channel needs rather than buying capacity you will not use.
Pros:
- 32 Midas PRO mic preamps with switchable 48 V phantom power
- 16 electronically balanced outputs
- Dual AES50 ports support cascading compatible DL16 stage boxes
- ULTRANET and ADAT connections add system options
Cons:
- May be more I/O than smaller setups need
- Its connections are most useful when they match your existing gear
Verdict: Pick the DL32 if you need 32 inputs, 16 outputs, and an AES50-based setup that can benefit from its Midas preamps and additional interfaces.
Behringer S32 with Surge Suppressor: High Capacity and a Power Block
This bundle combines a Behringer S32 stage box with a six-outlet SS-6B power strip. The S32 provides 32 remote-controllable Midas-designed preamps and 16 servo-balanced XLR outputs, giving it the same core I/O count as the other S32 option in this guide.
Two AES50 ports let you cascade compatible S32 units without a merger or router, and the description lists Klark Teknik SuperMAC technology for low-latency digital audio. Dual ADAT outputs, MIDI I/O, and USB for system updates round out the connections. The included power block has a heavy-duty metal construction and a 15-foot cord, which may be convenient when a stage or rack setup needs additional outlets.
The bundle’s extra value depends on whether you need the power strip; it does not add more audio inputs or outputs than a standard S32. As with the other AES50 boxes, check console compatibility and plan for the correct digital connection before choosing this model.
Pros:
- 32 preamps and 16 analog outputs
- Dual AES50 ports, ADAT, MIDI, and USB connections
- Includes a six-outlet power block with a 15-foot cord
- Useful I/O capacity for larger live rigs
Cons:
- The power strip adds little value if your setup does not need extra outlets
- Requires a compatible AES50 console or system
Verdict: Choose this bundle over a standalone S32 when the included power block is useful to your setup; otherwise, compare the bundle contents carefully before deciding.
How to Choose a Digital Stage Box for Live Sound
Match the Stage Box to Your Console
Start by checking the digital connection your mixing console supports. These products list AES50 networking, but you should confirm the exact compatibility requirements for your console and system before buying. A stage box is not a universal adapter, so a high channel count will not help if it cannot connect to your mixer.
Count Inputs and Outputs Separately
List every microphone and other stage input you expect to use, then leave room for instruments or additional performers. Next, count the outputs you need for monitor mixes and other stage sends. A 16-input, eight-output model may suit a compact setup, while 32 inputs and 16 outputs provide more capacity for larger productions.
Consider Your Monitoring Setup
If musicians use personal monitoring equipment, check whether the stage box’s ULTRANET connections fit the system you already own. The SD16 and larger models in this guide list ULTRANET features, but the connection is most useful when your connected mixers or other equipment support it. Do not assume it replaces every monitor output or monitoring component in your rig.
Check Expansion and Other Digital Connections
Think about whether you may add another stage box or need ADAT or MIDI connections. The S32 models and DL32 list dual AES50 ports, and the DL32 description specifically notes cascading compatible DL16 units. Check the product details for the exact connections you need rather than relying on the general term “digital stage box.”
Evaluate Bundled Extras
Bundles can be convenient, but their accessories solve different problems. The S32 cable bundle lists four 20-foot XLR microphone cables, while the other S32 bundle includes a six-outlet power block. XLR cables do not replace the digital network link, and a power strip is only useful if your setup needs its outlets and cord length.
Plan for Placement and Power
Consider where the stage box will sit, how its cables will reach the equipment, and how you will supply power at that location. Also check the stage box’s physical and mounting requirements in the full product listing. A layout that is easy to wire and access can make setup and changes during a live event simpler.
Frequently Asked Questions
What does a digital stage box do?
It brings audio connections to the stage and sends audio and control signals over a digital link to compatible mixing equipment. This can reduce the need for long analog cable runs between the stage and mixing position.
How many inputs do I need?
Count your microphones, instruments, and any other sources that need a stage connection. The SD16 has 16 inputs, while the S32 models and DL32 have 32. Leave some headroom if your setup may grow.
Are these stage boxes compatible with every digital mixer?
No. The products listed here use AES50, so check that your console supports the required connection and is compatible with the specific stage box. Confirm system requirements before buying.
What is ULTRANET used for?
ULTRANET provides a connection for compatible personal monitoring equipment and, where listed, compatible Turbosound systems. Check the connected equipment’s requirements to confirm that it will work with the stage box.
Do the bundled XLR cables connect the stage box to the mixer?
No. The four XLR cables listed with the first S32 bundle are microphone cables for analog audio connections. The digital connection is a separate link, described as Cat 5e for remote operation on that listing.
Should I choose the S32 or the Midas DL32?
Both offer 32 inputs and 16 outputs in the supplied product details. Compare the listed preamps, connections, and compatibility with your system. The DL32 specifically lists Midas PRO preamps, ULTRANET, ADAT, and cascading compatible DL16 boxes.
Is a 32-input stage box too large for a small band?
It may be more capacity than a small setup needs. If 16 inputs and eight outputs cover your stage plot, the SD16 may be a more suitable fit. Choose based on your actual channel and output needs, plus any room you want for expansion.
Final Recommendation
For a larger AES50-compatible setup, the Midas DL32 is a strong option when its 32 inputs, 16 outputs, and listed expansion connections fit your system. The Behringer S32 bundles offer similar core capacity, with the choice between extra XLR cables and a power strip depending on what your rig needs. For a smaller setup, consider the SD16 and make sure its 16 inputs and eight outputs are enough. In every case, confirm console compatibility and count your inputs and outputs before choosing.
