10-In 2-Out Analog Studio Matrix Source Selector – Balanced Line & Microphone Switcher

Balanced Analog Line / Microphone Source Selector – 0 dB Signal Path

The 10-In 2-Out Analog Studio Matrix Source Selector is a fully passive professional audio routing solution designed to independently route up to 10 balanced audio inputs to 2 separate balanced outputs.

Each input features an individual 3-position A / Mute / B rotary selector, providing direct control over the signal routing:

• A – Routes the selected input (1–8) to Output A.

• M (Mute) – Completely disconnects the input from both outputs.

• B – Routes the selected input (1–8) to Output B.

Both outputs can operate simultaneously, allowing independent source selection for two different signal paths.

IMPORTANT – SOURCE SELECTION LIMITATION

Each individual input can only be assigned to one output at a time. Only one input should be assigned to each output at any given time. The user must ensure that multiple inputs are not accidentally routed to the same output, as this would passively combine their signals. All unselected inputs remain electrically disconnected from both output buses, preventing unwanted signal connections and bleed.

+48V Phantom Power Compatibility

The unit also supports dedicated switching for +48V phantom-powered microphones. Phantom power routing is handled separately from the passive audio signal path, with dedicated switching for the Hot, Cold and Shield connections.

The unit does not generate phantom power; it routes the existing +48V phantom supply.

INDEPENDENT SOURCE ROUTING

All three XLR connections are individually switched and electrically isolated from one another:

• Pin 2 – Hot: Independently switched.
• Pin 3 – Cold: Independently switched.
• Pin 1 – Shield / Ground: Independently switched.

No signal connection is shared between sources. Only the selected source is connected to the corresponding output.

Important: Pin 1 must remain electrically separate from the XLR connector shell (Chassis). Please ensure that the cables used do not internally connect Pin 1 to the XLR shell, as this would bypass the independent Pin 1 switching.
