HARVEY Pro 19" DSP Controlled Audio Matrix with mixing, 1RU


HARVEY is a flexible audio and media control matrix and a key component for PA systems and conference systems.

HARVEY is available in different configurations regarding the number of analog IO channels and with or without Dante option. Until further notice, the configurations 12x16 and 16x16 are supported by HARVEY mx.16.

Audio and Control Matrix HARVEY

The new HARVEY product line, previously known as HARVEY 8x8 or HARVEY 8x8-DA, is now called HARVEY Pro. The name suffix "Pro" serves to clearly identify the current series, technically nothing changes.

HARVEY Pro is available in various IO configurations, which are appended to the name, e.g. HARVEY Pro 8x8, HARVEY Pro 16x8 or HARVEY Pro 8x8-DA

In addition to audio signal processing, lighting and media control, HARVEY Pro allows for a flexible response to different market requirements with regard to the number of channels. The audio input and output channels can be scaled in steps of 4, allowing HARVEY Pro to cover the spectrum from small projects with an 8×8 audio matrix to special applications with e. g. 4×24 channels. An appealing wall-mounted remote control for the most important functions completes the product portfolio.


The unit has extensive audio processing functions that can be configured in a way that is tailored precisely to the respective application. These settings can also be saved as a preset and retrieved at the press of a button so that you can change fast between different installation options.


Due to the varied control interfaces HARVEY mx.16 can connect to very different devices and act as a central control unit for audio, lighting and media technology. It converts the data between the interfaces and eliminates the need for additional converters. In addition to the new HARVEY Remote Control RC4 also all established media control systems are suitable for controlling HARVEY and all of the other devices connected to it.


The user interface of HARVEY mx.16, the HARVEY Composer, has a simple operating philosophy: The menu structure is clearly arranged, elements are composed in a project by drag & drop and configured immediately in the context menu. That allows you to configure complex projects with only a few mouse-clicks.

The user interface of HARVEY is characterized by its clarity and simple structures. It allows for intuitive use and enables every user to develop detailed planning layouts for complex projects in only a few steps. Learn More.
