Soundcraft EFX12 - 12-Channel Analog Mixing Console with 2 Stereo Channels and Built-in Lexicon Effects in Dark Blue Finish

The Soundcraft EFX12 is a 12-channel analog mixing console designed to offer professional-grade sound and flexible control in a compact, user-friendly format. It builds on the popular Soundcraft EPM mixer, incorporating a built-in 24-bit Lexicon digital effects processor, giving users access to 32 high-quality effects without the need for external gear. With a combination of 12 mono input channels, 2 stereo channels, and multiple connectivity options, the EFX12 is an excellent choice for live sound, studio applications, and multimedia setups where high audio quality and ease of use are essential.

The standout feature of the Soundcraft EFX12 is its Lexicon effects processor, which is known for its superior reverb and processing quality. This processor, based on the AudioDNA chip found in professional Lexicon products like the MX400, offers 32 studio-quality effects, including reverbs, delays, and modulation effects. Users can adjust effects parameters via 3 dedicated controls and utilize the tap tempo function for time-based effects. Additionally, the built-in effects section has a clip LED and mute function for fine-tuning and managing effects during live or studio use.

At the heart of the Soundcraft EFX12 is its GB30 microphone preamps, providing transparent, low-noise amplification for each input. These preamps, designed by Soundcraft's co-founder Graham Blyth for the company's 30th anniversary, are also used in larger professional consoles like the LX7ii and GB Series. This ensures that the EFX12 delivers the same high-quality sound expected in more expensive mixers. The console is equipped with a 3-band EQ with a swept midrange on mono channels and a 3-band EQ on the stereo channels, offering precise control over the tonal balance of each input.

Connectivity options include XLR and 1/4-inch metal jack inputs, RCA phono playback inputs, and record outputs, making the Soundcraft EFX12 versatile enough for a variety of sound applications. Each mono channel features TRS insert points for connecting external processors, while a configurable aux send allows for flexible routing to monitors or external devices. The ten-segment LED output metering provides accurate monitoring of output levels, and the intuitive solo system and headphone output enhance user control over monitoring and mixing.

Compact, durable, and easily rack-mountable, the Soundcraft EFX12 is built to withstand the demands of live sound environments while being equally at home in the studio. Its professional features, combined with an easy-to-navigate interface, make it a solid choice for musicians, sound engineers, and venues requiring reliable performance and high-quality sound.
