The Sound craft EFX Series combines all the features of the popular Sound craft EPM mixer with a built-in 24-bit, digital Lexicon effects processor, expanding the Sound craft low-cost, multipurpose compact range. The Sound craft EFX8 mixer uses the same Audio DNA processor featured in many of the Digitech and Lexicon outboard equipment including the highly respected Lexicon MX400 processor. With over 35 years experience, the Lexicon name is synonymous with the best reverb and processing in the business, ensuring the finest quality effects not usually found in a console at this price level. The Effects section fits neatly into the mixers compact framework which is available in 8 or 12 mono input variants, both with 2 stereo channels and an effects send on each channel. There are 32 effects to choose from with a tap tempo function, 3 effects parameter controls and a user effects setting store facility. An effects channel level clip LED and Mute function gives the user even more flexibility. The emphasis with the Sound craft EFX is very firmly on quality build and audio performance, with an easy to understand control surface in line with the Sound craft professional range. The Sound craft EFX8 uses the highly-transparent GB30 Mic amp (designed by Graham Blyth for the company’s 30th anniversary, and also used on the larger LX7ii and GB Series professional consoles). The Sound craft EFX also offers all the features of the Sound craft EPM most notably a configurable aux send, XLR and ¼” metal jack connector sockets, RCA phono stereo playback inputs and record outputs, 3-band EQ with a swept mid on the mono inputs, 3-band EQ on the 2 stereo inputs, TRS insert sockets, inserts on all mono inputs, ten-segment LED output metering and a headphone output.
