Spec Sheet

The 4‑Series Control System (MC4) provides a secure, high‑performance, cost-effective control processor and interface. Its small form factor and versatile mounting options makes it ideal for smaller systems such as single‑room media systems, small to medium‑sized homes and offices, and MDUs (multidwelling units). The MC4 includes a built‑in infiNET EX® and ER wireless gateway for acquiring wireless devices as well as numerous control ports for controlling wired devices.

4-Series Control Engine
4-Series control systems come equipped with an upgraded multicore CPU, delivering a sizable speed and performance increase compared to all Crestron 3‑Series® control processors. The improved performance allows 4-Series control systems to handle the increasing demands of an advanced automated system. Crestron 4-Series delivers a dynamic and secure control system platform capable of managing a room full of disparate technologies.

Reliable networking and IP control afford seamless integration with other systems and devices, with add-on control capability using Crestron touch screens, wireless remotes, and mobile device apps, as well as remote management through Crestron Fusion® software and the Crestron XiO Cloud™ service.

Modular Programming Architecture
The MC4 is designed to run a single program out of the box. The optional modular programming architecture add-on allows the MC4 to run up to ten programs simultaneously.1 Programmers can develop and run independent, device‑specific programs, enabling each program to be optimized for a specific function and allowing for changes to be made to one program without affecting the whole system.

Onboard Control Ports
Through a full complement of onboard control ports, the MC4 can be integrated with a wide variety of audio, video, lighting, motorized shades, thermostats, door locks, sensors, security systems, and other equipment.

  • Gigabit Ethernet provides an interface for connecting to the building network and controlling Crestron AV switchers, audio processors, power controllers, and other IP controllable equipment.
  • Cresnet® network connectivity provides support for Crestron lighting dimmers, motorized shades, sensors, thermostats, keypads, and more.
  • Onboard RS‑232, IR, relay, and Versiport I/O control ports enable direct integration with all types of third‑party equipment.
