The ME-2A module preamplifier from RCS Audio-Systems is an installation device for program input and expansion of up to two audio source modules. It serves as an interface between the audio source modules and subsequent amplifiers or power amplifiers in sound systems. The device is designed for use in professional installations where flexible and modular signal processing is required. Module integration is simple, as all necessary connections and connectors are either built into the device or located on the rear panel.

Applications

The ME-2A is intended for use in sound systems, particularly in installations featuring multiple audio source modules, such as CD players, MP3 players, or other digital sources. It can be used in radio broadcasting systems, event technology, schools, hospitals, or other facilities where central control of multiple audio sources is required. The device is suitable for both 19˝ rack mounting and tabletop operation, with mounting brackets attached to the device and easily removable for tabletop use.

Functions and Features in Detail

The ME-2A features two separate balanced XLR outputs, each assigned to an audio source module (Module 1 and Module 2). Additionally, a sum output is available, enabling the combination of both modules. Volume control is performed via the controls on the respective audio source modules, allowing individual level adjustment per source. The outputs are unbalanced XLR, with a maximum output voltage of 0.775 V (0 dBu) and an impedance of 600 Ohm.

Technology Explained Simply

The frequency response curve of the ME-2A is within ±0.5 dB from 20 Hz to 20,000 Hz, ensuring linear and distortion-free signal transmission across the entire audible range. The signal-to-noise ratio is better than 68 dB, ensuring clear and low-noise transmission. Power supply is via mains voltage 230 V AC (50/60 Hz), with an optional backup power supply via 24 V DC. Power consumption is approximately 25 W. The device dimensions are 483 mm (width) × 88 mm (height) × 350 mm (depth), corresponding to 2 RU. The weight is approximately 5.0 kg.

Compatibility and Accessories

The ME-2A can be directly connected to any mixing power amplifier or power amplifier. Compatibility with audio source modules is ensured by the modular design. Specific module types are described in the product documentation on the manufacturer’s website.

Mounting and Installation

Mounting is either in a 19˝ rack or as a tabletop unit. The necessary mounting brackets are attached to the device and can be easily removed to enable tabletop operation. Connections are located on the rear panel of the device, allowing for clear and organized cabling. Installation requires no special tools, as modules are simply inserted into the designated sockets.

Advantages in Operation

The ME-2A offers a flexible and scalable solution for integrating multiple audio sources. Individual volume control per module enables precise signal management. The ability to operate the device both in a rack and as a tabletop unit increases operational flexibility. The backup power supply via 24 V DC ensures continuous operation even during a power failure, which is advantageous in critical applications. The robust construction and clear signal transmission make the device a reliable component in professional sound systems.
