MPK801 Multi-Channel

Many microphones. One synchronized array.

The ARK141 Sensor Hub synchronizes every MPK801 in the array to within 100 ns, so you can compare and combine channels with confidence. Up to 14 microphones per hub.

The Sensor Hub

One hub to synchronize them all

Built for industrial environments, not just your desk. Full environmental ratings in the datasheet.

The ARK141 Sensor Hub connects up to 14 MPK801 microphones, delivering power and data to each one over a single Sensor Cable and keeping every channel synchronized to within 100 ns. At its core, the ARK141 is an Ethernet switch that doubles as the master clock, distributing sync to every connected microphone. No per-channel preamp rack, no multichannel converter - just add a mic to add a channel.

The Microphone

Ruggedized precision broadband measurement microphone

Precision engineered, with the durability to go from the bench to the factory floor. Full environmental ratings in the datasheet.

The MPK801 simplifies audio capture and reduces array costs. Pre-calibrated and compensated microphones deliver high-quality data up to 80 kHz, consistent to ±0.5 dB from unit to unit, so channels are directly comparable. Industrial M12 cables carry data and power to each microphone on a single connection to the ARK141 Sensor Hub. Calibration data lives on each microphone and is applied automatically, so a replacement drops straight in with no recalibration and no model retraining.

Pricing

Your total is built from one ARK141 Sensor Hub plus the number of MPK801 microphones you need, from 2 to 14. You set the microphone count on the next step and calculate the total.

Custom configuration

Starts at 1× ARK141 + 2× MPK801, adjustable up to 14 mics per hub.

Software & Data Integrity

Built for data you can trust

The MPK801 is engineered around the integrity of your data stream. Built-in packet-loss tracking means you always know your recording is complete, and heartbeat monitoring flags any microphone the moment it stops reporting - so nobody has to check by hand whether data is still arriving.

Heartbeat monitoring - a failed unit is identified by name the moment it stops reporting

Packet-loss tracking for verified, complete recordings

On-sensor calibration data, applied automatically. Swap a unit and keep measuring, with no recalibration and no model retraining

Linux audio driver (ALSA) - one input device, one channel per microphone, no per-device enumeration

A Windows driver and a Python API will be available at the end of 2026.

Applications

Independent MPK801s give you parallel measurements. Synchronization through the ARK141 gives you three things they can't.

Cross-asset correlation

Build models that recognise when event B on machine 2 reliably follows event A on machine 1. Synchronization within 100 ns captures timing relationships across separate assets, not just within each one.

Cross-sensor validation to reduce false positives

Simultaneous, correlated readings from multiple positions confirm real events rather than firing on any one microphone's noise. Independent recordings cannot do this; synchronized ones can.

Spatially-diverse dataset generation

Capture the same acoustic event from multiple angles at the same instant. Richer training data than single-microphone datasets can produce, at a fraction of traditional multi-channel DAQ cost.

Specifications

MPK801 in a synchronized array

Acoustic performance is identical whether an MPK801 runs standalone or in an array. What changes is how it is connected, powered and synchronized — shown first below.
