Connectivity and compatibility

The MX400SMP uses a five-pin XLR connector that carries both balanced audio and logic signals, simplifying the wiring and control setup. Its logic-enabled LED input allows integration with room controllers to manage microphone status lights remotely. This makes it well suited for conference rooms, council chambers, and classrooms where clear communication and easy status monitoring are essential.

Installation and setup

Installation requires drilling a single 1-inch hole in the mounting surface, where the preamp drops into place and secures firmly. The design includes rubber isolation rings that separate the unit from the mounting surface, effectively reducing vibrations and table noise. This straightforward setup keeps wiring tidy and concealed, making it ideal for permanent installations in professional environments.

Ideal uses and environments

The MX400SMP fits well in corporate meeting rooms, council chambers, houses of worship, and educational settings where high-quality audio and reliable microphone control are critical. Its ability to reduce background noise and protect against RF interference ensures clear, uninterrupted sound even in busy spaces with multiple electronic devices. This preamp is a strong choice for any installation requiring clean gain staging and easy microphone status monitoring.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
