The ARX MSX 32 BST is a high-performance 8-input, 32-output active microphone and line splitter designed to meet the rigorous demands of modern audio production. Built for live sound, broadcast, and installed systems, the MSX 32 delivers pristine audio, exceptional headroom, and flexible routing in a rugged 2 RU format—making it an ideal solution for complex signal distribution setups.
- 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.
- 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.
- 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.
Internally, high-grade components and powerful RF filtering ensure outstanding common mode rejection (CMRR) and resistance to interference, even in challenging environments.
