KEY FEATURES

32 Microphone Channels

The device features 32 low-noise channels, each configurable for various input types, including dynamic, 48V, LEMO (200V), 4mA (28V) CCP/ICP/IEPE/CCLD microphones/accelerometers and line. The gain can be set in calibrated 6dB steps. The frequency range covers 5Hz to 40kHz. Input channels can also support DC coupling upon request.

Dual Headphone Amplifiers

The MICAMP M-32 features two independent headphone amplifiers, each with individual
controls and solo functionality for every input.

Line Outputs

The MICAMP M-32 is equipped with 12 line outputs, making it ideal for use with Dolby Atmos® systems.

Optional USB Streaming

Two channels can be sent though USB audio. This feature enables seamless streaming of audio to devices such as a car head unit via a Bluetooth-enabled smartphone.

Power Input

The MICAMP M-32 is powered by an external power-source accepting 10 – 18 V. The units maximum power consumption is 100 W with all channels activated and the power amplifier running at full power, but much care has been taken to only power the absolute necessary for battery powered use cases.

Digital Output Control

The device is equipped with 8 automotive- grade digital outputs for controlling external devices such as amplifiers, speaker switches, relays, and similar equipment. These outputs can be managed remotely through the provided software or via third-party MIDI-enabled software or hardware.

MIDI over MADI controllable with TEDS

The configuration of MICAMP M-32 is made via conventional MIDI or MIDI over MADI which enables a completely galvanically isolated device. Each channel can read TEDS data from the microphone and calibration data from the amplifier for each gain step.

Optional Speaker Measurement

The MICAMP M-32 has the ability to replace two input channels with current and voltage measurement to measure speaker impedance. The device is equipped with a 2x20W amplifier, providing flexibility for users to choose between utilizing the internal amplifier or connecting an external one for their measurement needs.

Automatic Clock Sync

The interface includes an advanced clock synchronization function, allowing it to synchronize with various master clocks. An internal clock is available if no external clock is provided. The clock circuitry is designed with extremely low jitter, ensuring high precision. A word clock output is also provided, and all word clock I/O is fully galvanically isolated.

AES/EBU and S/PDIF

The MICAMP M-32 includes 8 fully galvanically isolated AES/EBU inputs and 8 fully galvanically isolated outputs. The inputs are completely clock independent and are re-clocked to the low jitter internal clock circuitry.

Intuitive software control​

The amplifier can be controlled by the supplied software or with third-party software through MIDI scripting. All TEDS data can be exported to csv or displayed directly in the software. When the device has received a change, it automatically stores the configuration to non-volatile memory. The device can also be used as a standalone unit. Each channel’s configuration is reflected both on the device’s front panel and in the software interface. All channels are monitored for clipping, there is also a signal detect indication for each channel in both the software and the front panel.
