The FMX-1602 from RCS Audio-Systems is a professional audio mixer with 16 input channels, designed for use in sound reinforcement systems, studios, events, and fixed installations. The device features extensive sound control and an integrated effect processor, making it suitable for both live and studio applications. It can be operated as a tabletop unit and can optionally be integrated into rack systems using a 48,3 cm ( 19 inch ) rack mounting kit (RMK-16, 8 HE).

Applications

The mixer is suitable for a wide range of applications, including professional sound reinforcement systems, recording studios, conference technology, and events. The combination of flexible inputs, comprehensive channel controls, and integrated effects makes it particularly suitable for users requiring precise sound shaping and flexible signal routing. The option to install the device in a rack increases its versatility in professional installations.

Functions and Features in Detail

The input section includes 10 mono channels (CH 1–8 as MIC/LINE, CH 9/10 and 11/12 as stereo) and three additional stereo channels (CH 13/14 and 15/16). The mono channels are equipped with gain, trim, 4-band EQ, and a low-cut filter at 75 Hz. The stereo channels feature 3-band EQs and pad switches (–20 dB) for CH 9/10 and 11/12. Pan and balance controls allow for precise sound distribution in the stereo field. Channels CH 1 and CH 2 offer insert points for external effect devices. A central +48 V phantom power switch supplies condenser microphones. Two AUX paths (pre- and post-fader) provide flexible signal routing.

Technology Explained Simply

The FMX-1602 features an integrated DSP effect processor with 16 preset effects that can be mixed into the main sum or monitor sum. Input sensitivity is –55 dBu for microphones and –35 dBu for line inputs (mono), and –20 dBu for stereo inputs. Output impedance is under 100 Ohm for all outputs, and 1 kOhm for tape out. The frequency response ranges from 20 Hz to 60 kHz (+0 / –1.5 dB), enabling broad sound reproduction. Signal-to-noise ratio exceeds 90 dB, and crosstalk attenuation is more than 85 dB, ensuring clear channel separation. EQ ranges include highs (12 kHz ±15 dB), high mids (3.0 kHz ±12 dB), low mids (800 Hz ±12 dB), and lows (80 Hz ±15 dB). The low-cut filter at 75 Hz with 18 dB/octave reduces unwanted low frequencies.

Compatibility and Accessories

The device is compatible with an optional 48,3 cm ( 19 inch ) rack mounting kit (RMK-16, 8 HE), enabling integration into standard rack systems. Inputs consist of XLR and 6.3 mm jack sockets for mono channels, and 6.3 mm jack sockets for stereo channels. Two RCA inputs (2-Track IN) are also provided.

Mounting and Installation

The FMX-1602 is delivered as a tabletop unit and can optionally be installed in a 48,3 cm ( 19 inch ) rack using the RMK-16 rack mounting kit. Dimensions are 411 mm (width) × 354 mm (depth) × 72 mm (height, excluding feet). The device weighs approximately 5.7 kg. Power supply is 220–240 V AC at 50–60 Hz, with a power consumption of 25 W.

Operational Advantages

The combination of comprehensive channel controls, flexible routing options, and the integrated DSP effect module enables precise and creative sound shaping. Central phantom power and support for insert points increase flexibility when using external effect devices. High technical specifications such as signal-to-noise ratio and crosstalk attenuation ensure clear and clean audio transmission. The ability to operate the device both as a tabletop unit and in a rack increases its versatility across various application scenarios.
