RCS Audio-Systems ME-1 A Module preamplifier, 1 U content_copy

The ME-1A module carrier from RCS Audio-Systems is a module preamplifier in 1 U format, specifically developed for professional sound reinforcement systems and audio installations. It serves as a base unit to integrate up to two AM-series source modules space-savingly, enabling a flexible and modular audio infrastructure. The device is designed for use in 48,3 cm ( 19 inch ) racks as well as for desktop use, making it suitable for various applications such as studios, conference systems, or emergency call systems.

Applications

The ME-1A is particularly suitable for applications where multiple audio sources need to be combined in a compact format. The ability to install freely combinable AM modules allows for customized configurations – for example, combining a DAB tuner with a USB/SD player or an RDS tuner with a CD player. The integrated priority logic makes the device especially interesting for security and emergency call systems, where certain signals (e.g., emergency announcements) automatically take precedence over other sources.

Functions and Equipment in Detail

On the rear of the device, there is one stereo RCA output per module (Channel 1 and Channel 2), allowing the signals from individual modules to be output independently. Additionally, a stereo RCA priority output is provided, which prioritizes the signal from the right-installed module (Module 2). As soon as playback of this module ends, an automatic, seamless switch occurs to the left module (Module 1). This function enables continuous audio output without interruption, which is advantageous for critical applications.

Technology Explained Simply

The power supply of the ME-1A is designed flexibly: the device can be operated either via 230 V AC mains voltage or via a 24 V DC backup power supply, ensuring continuous operation even during a power failure. The dimensions are 483 mm (width) × 43 mm (height) × 295 mm (depth), corresponding to the standard format 1 U. The device weighs 2.8 kg and is thus light enough for desktop placement, yet stable enough for rack use.

Compatibility and Accessories

The ME-1A is designed for use with AM modules, which are connected via a standardized socket. The inputs include a 75 Ohm coaxial antenna input for radio modules, a whip antenna connector, and a Record-In connector (stereo RCA) for external signal transmission. The outputs are also configured as stereo RCA, enabling universal connection to amplifiers or speakers.

Mounting and Installation

The device is designed for 48,3 cm ( 19 inch ) rack mounting and features the necessary mounting holes. Alternatively, it can also be used as a desktop unit, with its dimensions and weight ensuring stable positioning. Installation involves inserting the desired AM modules into the two sockets and then connecting the inputs and outputs.

Advantages in Operation

The ME-1A offers high modularity and space-saving by combining multiple functions in one device. The priority function ensures reliable signal transmission, especially in critical scenarios. The dual power supply (mains and backup) increases operational reliability. The RCA connectors enable easy and universal integration into existing audio systems. The device is thus a compact, flexible solution for professional applications that prioritize efficiency and reliability.
