Product Description

Here’s What RCF Say About the M 20X Desktop Digital Mixer

M 20X is a fully recallable mixer, with 16 remote controlled preamps and 11 motorized faders. Despite its dimensions, the M 20X packs a whole suite of capabilities, such as high-profile preamplifiers, top of class DSP with studio-quality processing, WiFi remote control and a comprehensive set of multitrack recording and playback functions. The mixer offers a total of 20 analog inputs and 14 output channels, between the balanced analog outputs and the AES/EBU digital output.

M20 MixRemote App

Complete remote control of all M 20 models is available with M20 MixRemote, a dedicated App developed for both iOS and Android.

Enhanced FX Engines

Four buses are dedicated to internal FX engines, arranged as two high-quality digital-reverbs, a programmable delay and a fourth FX which can be configured as delay or modulation. All FX engines offer multiple algorithms to match the specific needs of a show. It is possible to reserve one reverb for some inputs and use the second reverb as a general-purpose FX for other sources.

Record & Playback

All 20 inputs can be recorded in multitrack WAV format on the local SD card, and played back as channel inputs, no computer required. A 24-track, 24-bit, 48-kHz low-latency USB audio interface is available and allows access to all inputs and several internal signal nodes. Extensive routing options allow both offline soundcheck and host-based effects processing. A flexible stereo file player can access USB mass storage devices (up to four different drives), with arbitrary sample rate, in MP3, WAV, and AIFF formats.
