From Summit Audio

Unique passive design

The Summit Audio FeQ-50 draws from years of research and experience to be able to fit a true tube passive design into a chassis of this size. Coveted by top professionals for decades, passive EQs have better phase coherence, and the inductors offer a rich, smooth harmonic quality.

This and that

The FeQ-50 provides both tube and solid-state outputs, each with their own 1/4” (-10) and XLR (+4) jacks. With four simultaneous outs available, you can do all sorts of multi-tracking tricks with a single signal.

Parametric 4 band EQ

The FeQ-50 is a four-band passive equalizer covering the entire audible frequency spectrum, so it can be used on any audio source material. You can subtly sculpt and fine-tune an instrument or vocal to make it fit perfectly into a mix, or you can totally transform a sound into something entirely different and new. 

Really well built

The Summit Audio design philosophy considers the entire package when it comes to crafting gear. We pay special attention to the details of construction and have included many refinements over the years so units are durable enough to handle the rigors of the road. That is one of the reasons why you will find Summit gear on tour with many of today’s top touring acts around the world.

Hand-crafted in the USA

Each piece of Summit gear is meticulously crafted by hand in our shop using only the best quality components and attention to detail. Quality components and engineering know-how are the critical element to the sound and longevity of audio gear.
