Single-channel EQ with a characteristically warm sound

The Summit Audio FeQ-50 is a single-channel, 4-band, parametric EQ with iron-based circuitry. The FeQ-50 was designed to be a sonically warm and harmonically pleasing equalizer that adds character and depth to any signal.

Switch-selectable frequencies plus low and high shelving

Each of the Summit Audio FeQ-50’s four bands features switch-selectable frequencies with six frequencies on each band, as well as fully sweepable gain of +/- 14dB with a center detent at 0dB. The low and high bands feature peaking or shelving select, the middle two bands with wide and narrow switches. The FeQ-50’s fully passive highpass filter has a knee at 30Hz with a 6dB-per-octave roll-off, while the signal path is transformerless.

Both XLR and 1/4″ inputs with balanced and unbalanced outs

Housed in Summit Audio’s 1/2 rack chassis, the FeQ-50 is very versatile when it comes to I/O. Both XLR-balanced and 1/4″ unbalanced inputs are accommodated on a Neutrik combo jack. For outputs, the FeQ-50 has balanced +4dB XLR and balanced -10dB TRS for both the solid-state and tube signal paths, all of which are individually buffered and can be used simultaneously.

Like all Summit Audio products, the FeQ-50 has an internal high voltage power supply and has a 3 year warranty.
