ARX MSX 32 8x32 Active Microphone/Line Splitter (BST)

Eight Channels, Four Splits per Channel

Each of the MSX 32 BSTs eight channels provides four independent outputs:

• A and B splits on the front panel, transformer balanced
• Main and Monitor outputs on the rear panel, electronically balanced (with optional transformer balancing)

A Link switch enables signal chaining from one channel to the next, allowing a single input to feed up to 32 outputs, making the MSX 32 ideal for press feeds, large FOH/monitor splits, or broadcast distribution.

Clean, Flexible Gain Structure

Each input features:

• A rotary gain switch with selectable gain from 0 to +40 dB (in 10 dB steps)
• A ?20 dB pad switch with LED indicator
• A 48V phantom power switch with silent switching via ARX?s SilentSwitch technology

This flexible gain control and input padding ensures compatibility with a wide variety of signal sources, from condenser mics to hot line-level feeds.

Onboard Monitoring and Metering

The MSX 32 BST includes:

• PFL (Pre-Fade Listen) switches on each channel
• 6-LED signal-level metering for precise visual feedback
• Headphone output with level control for signal monitoring and troubleshooting
• PFL loop connectors for linking monitoring between multiple MSX 32 units

These tools provide technicians with quick, reliable ways to check signal integrity and trace routing issues in complex systems.

Built for Mission-Critical Environments

The MSX 32 BST operates via a low-noise, internal toroidal power supply, with support for the optional PSU 32 redundant power unit. Front-panel status LEDs indicate when backup power is connected, giving operators visual assurance of continuous system operation.

Internally, high-grade components and powerful RF filtering ensure outstanding common mode rejection (CMRR) and resistance to interference, even in challenging environments.

Robust Construction and Smart Layout

Housed in a rugged 2 RU all-steel chassis, the MSX 32 BST features an intuitive, user-friendly front-panel layout and professional-grade XLR I/O throughout. All connections are clearly labeled, and rack ears are built in for easy installation.
