The RCS Audio-Systems FMX-1202 is a professional audio mixer with 12 channels, designed for use in event technology, live events, studio operation, and similar applications. The device features a modular input structure that can process both microphones and line signals, offering flexible signal distribution via various outputs and Aux paths. The design allows for use as a tabletop unit or installation in a 19-inch rack, with mounting brackets RMK-12 available as an option.

Applications
This mixer is suitable for applications requiring clear and flexible signal processing from multiple sources. These include live events, conferences, training sessions, small studio recordings, or as a central mixing station in multi-channel systems. The combination of mono and stereo inputs along with integrated effects makes it particularly versatile for scenarios requiring quick adjustments to sound design.

Functions and Equipment in Detail
The input section includes 6 mono input channels, which can be operated via XLR connectors for microphones or via 6.3 mm jack connectors for line signals. Channels 5/6 and 7/8 are configurable as stereo inputs via two 6.3 mm jack connectors each, while channels 9/10 and 11/12 can be used either as mono (L) or stereo (L/R) via 6.3 mm jack connectors. Mono channels 1 to 4 feature separate preamplifier settings for MIC (Gain) and LINE (Trim), a 3-band channel EQ, and a Low-Cut switch at 75 Hz. Channels 5/6 and 7/8 include a Pad switch (-20 dB) and a 3-band channel EQ, while channels 9/10 and 11/12 are also equipped with a 3-band channel EQ. Signal distribution is managed via pan controls for mono signals and balance controls for stereo signals. An adjustable headphone output allows monitoring of all channels, with a solo function per channel available for precise checking of individual inputs. Each channel has an assignment selector for the main mix (Main L/R) and an alternative sum output (Sub 1/2). Phantom power (+48 V DC) for all microphone inputs is centrally switchable.

Technology Explained Simply
The mixer provides two Aux paths: one pre-fader and one post-fader, which can be used for monitor or effect applications. The main mix outputs (Main L/R) are available via XLR balanced connectors and 6.3 mm jack connectors (unbalanced), controlled by stereo faders equipped with LED meters for level indication. Two additional alternative outputs (Sub 1/2) via 6.3 mm jack connectors are also available and controlled by dedicated faders. For integrating 2-track recording or playback, two RCA inputs (with level control) and two RCA outputs (L/R) are provided. Two unbalanced Aux send and two adjustable Aux return inputs are also integrated, with the returns optionally switchable to the monitor path.

Compatibility and Accessories
The FMX-1202 mixer is designed for use in 19-inch racks, with mounting brackets RMK-12 (8 HE) available as an option. The integrated effects engine offers 16 digital effects, which can be mixed into the overall sum via an adjustable DSP master. The effects can also be switched to the monitor path via a selector and can be turned on and off using a separate foot switch. An additional preamplified signal output via a mono-out jack connector with level control is also available.

Mounting and Installation
The device can be operated as a tabletop unit or installed in a 19-inch rack, with mounting brackets RMK-12 available as an option. Installation requires no special tools, as mounting is done via standard rack holes. Operation is performed via front panel elements, which provide all necessary controls and switches for signal processing.

Advantages in Operation
The FMX-1202 offers clear, intuitive operation with good signal distribution and flexible input structure. The integrated effects and the ability to control them via a foot switch increase efficiency in live applications. The combination of mono and stereo inputs along with separate Aux paths enables precise sound shaping. Central phantom power and LED meters for the main mix support professional signal processing. The ability to use the mixer as a tabletop unit or installed in a rack increases operational flexibility.
