M4x Blade Communication System

M4x Blade


Raven Electronic's M4x Blade quickly connects to your laptop via USB or ethernet to provide voice communication solutions. At the heart of the M4x Blade are DSP (digital signal processor) powered “modules”. They provide “access points” for several different types of communication equipment including radios, telephones, orderwire, and even alarm and control equipment.

Event-driven, intuitive software enables you to configure the ports as necessary.

The M4x Blade can accommodate up to eight access points, and under software control, can bridge or conference them in any combination. And that’s just the beginning of the versatility the M4x Blade offers. You can easily set it up for SNR voting, 800 MHz rebanding, conventional radio simulcast, repeater intertie, incident response, interoperability, and system troubleshooting. Choose up to 4 different modules (for up to 8 individually configured ports) based on your needs.

M4x Mini-Blade Communication System

The versatile and economical M4x Mini-Blade can also quickly connect to your laptop via USB or ethernet to provide voice communication solutions. It has two ports and offers the same easy-to-use software as the eight port M4x Blade for added flexibility. In addition to functioning in all the same ways as a bridge, it provides many more features and capabilities, such as: tone remote control, 2175 notch filter, or voice frequency switch.

Event-driven, intuitive software enables you to configure the ports as necessary.

The M4x Mini-Blade has just the right number of ports to perform the following: VOX and audio delay, DTMF radio channel steering, and troubleshooting. The 4-wire module comes standard with every Mini-Blade. However, there are other modules available to provide greater flexibility. 

M4x Interface Modules

2 Port 2-Wire/4-Wire Analog VF/VOX

This two-port module has a 2-wire and a 4-wire interface. This module has the capability of DTMF detection, VOX detection with relay output, voice delay up to 1 second on each channel, M-lead (PTT) relay outputs and E-Lead (COR) inputs. The input can be 600 ohm or high impedance, and output is always 600 ohm. This module is designed for very low frequency signals. It also includes the added feature of automatic gain control.


I/O Interface

This module has the capability of monitoring or control of up to 16 control points. Each line can be programmed as either an input or an output.


Conference Bridge

This module is a conference bridge for large multi-blade systems that need conferencing capabilities.



3-channel module that incorporates Digital Voice Systems' AMBE 3003TM Vocoder technology. It is used for gateway applications for digital mobile radio systems for JVC Kenwood NEXEDGE. (One module for every three talk paths)



2 Channel RS-232 Interface

(2) ports Module, Inputs & Outputs can be routed to the host computer or other RS-232 ports.


2-Port Telephone

Two channels for 2-wire and 4-wire telephones, restricted to two modules per single blade.



Based on a field-proven VoIP engine, our VoIP solution provides a new dimension in power for the M4x product line. It's not just another VoIP product, it's a digital control mechanism for voice and data services that is integrated with our entire line of M4x module products including radio, telephone, I/O, and serial modules.


Relay Interface

This Relay Module has six DPDT relays or eight SPDT relays



Two channels for connecting 2-wire circuits with telephone battery voltage applied.
