16 Channel Customizable Passive Analog Summing Mixer – Select D-Sub / TRS / XLR Connections, 2 or 4 Outputs

16-Channel Customizable Passive Analog Summing Mixer

A professional 16-channel passive analog summing mixer, built to match your studio setup.

You choose the connectors. You choose the output configuration.

This 1U rackmount summing mixer combines up to 16 balanced input channels through a passive analog summing network. It is designed for connecting DAW audio interfaces, synthesizers, keyboards and other studio equipment.

Choose Your Input and Output Connections

The connector configuration is customizable when ordering. You do not have to use a fixed connector layout.

Input connections – choose one:

• D-Sub
• TRS Jack
• XLR

Output connections – choose one:

• TRS Jack
• XLR

Output configuration – choose:

• 2 balanced output channels
• 4 balanced output channels

Your selected connector types and output configuration will be built into the unit.

8 Stereo-to-Mono Switches – 16 Individual Mono Inputs

The mixer features 8 independent Stereo-to-Mono switches.

Each switch converts one stereo input pair (Left + Right) into two separate mono input channels.

This means you can use the mixer in different configurations:

• 8 stereo input pairs
• Up to 16 individual mono input channels
• Any combination of stereo and mono inputs

For example, you can use separate mono inputs for Kick, Snare, Bass and Vocals, while keeping synthesizers and other stereo instruments in stereo.

When a Stereo-to-Mono switch is disabled, its input pair operates as a normal stereo pair.

This gives you control over how the 16 input channels are allocated in your DAW.

Fully Balanced Passive Analog Signal Path

The mixer uses a passive analog summing network with selected Vishay Dale military-specification metal-film resistors.

• No power supply required
• No active amplification stages in the signal path
• Balanced input and output architecture
• Point-to-point hand wiring
