Soundcraft EFX12 – 12-Channel Analog Mixer with Lexicon Effects

Product Overview

The Soundcraft EFX12 is a 12-channel analog mixer built for live sound, houses of worship, and multi-speaker installations that demand both audio quality and built-in effects. Combining the professional GB30 mic preamp design with a 24-bit Lexicon digital effects processor, this analog mixer delivers signal processing quality typically reserved for outboard gear. The EFX12 is a strong choice for sound engineers seeking a Soundcraft analog mixer with Lexicon reverb in a rack-mountable, compact chassis. Its straightforward channel strip layout and 32 onboard effects presets make it practical for both installed and portable applications.

Product Description

The Soundcraft EFX12 builds on the proven EPM platform by adding a full-featured 24-bit Lexicon digital effects section powered by the same AudioDNA processor found in Lexicon's MX400 outboard unit. The 12+2 channel frame includes 12 mono XLR/TRS combo inputs and 2 stereo input channels, each with an FX send for routing signal to the onboard effects engine. The GB30 mic preamp — designed by Soundcraft's Graham Blyth — provides +22dB of headroom and transparent gain across a 55dB range, making it suitable for condenser and dynamic microphones alike.

The effects section offers 32 presets covering reverb, delay, chorus, and specialty programs including a custom karaoke preset. Tap tempo allows real-time BPM synchronization of delay effects, and a user effects store function saves a custom configuration for recall. The configurable auxiliary bus can be used for monitor sends or outboard processing, and TRS insert points on all mono channels allow inline signal processing without breaking connections. RCA phono inputs and record outputs provide a convenient stereo playback and recording loop compatible with consumer sources. Ten-segment LED output metering gives a clear visual reference for output levels, and the headphone output with its own level control allows independent monitoring without disturbing the main mix.

The EFX12 is easily rack mountable using optional rack ears, making it suitable for both tabletop and installed rack deployments. The 3-band EQ with swept mid on mono inputs and 3-band EQ on stereo channels gives engineers precise tonal control. The comprehensive solo system allows individual channel isolation for monitoring and troubleshooting during live events. Available from Creation Networks, the EFX12 is well suited for AV integrators and worship tech teams looking for a reliable analog mixing console with onboard effects.
