The resør 3300 is our latest addition to the rotary mixers. It features a fully discrete class-A Master Isolator, 3-Band EQ per channel, a dedicate  Microphone input with volume control, four Phono/Line preamps, Urei-style knobs, and more.

With this model, we bring an all-new discrete master Isolator developed over six months. The new class-A circuitry carries over the 24 dB /Oct filters, crossover frequencies, bypass Relay, and a "full cut" to a maximum boost of +12 dB. With the staggering number of components, including 28 BJT and 32 FET transistors, we have achieved outstanding performance in sound and measures. 

The 3-band channel EQ is an entirely new design. It brings a fresh set of frequency curves and attenuation levels across all three bands, a lower noise floor, and retaining our discrete Op-Amp on duty. 

There is a different curve across these two segments, with the Isolator having a more pronounced sweep and color. In use, this means that per channel, you get to craft your sound via the EQ and then craft further still with a different tonal balance with the Isolator. 

Across the EQ and Isolator, plenty of headroom is available across all frequency ranges, providing plenty of control when crafting the audio. 

Each of its four channels features hi-fi Phono and Line inputs. With Phono preamps delivering 44 dB of Gain, both vinyl and digital are well-balanced. Further refinements on the Phono preamps gave us even more pleasing dynamics, headroom, and a broader frequency spectrum.

We offer an additional element of customisation that one can specify when they place their order, ranging from adding an FX-bus, changing the combination of colours for the faceplate to different wood finishes and knob options.

With added FX-bus, the resør 3300 FX offers plenty of possibilities to expand your setup further by adding an external FX unit and apply those per channel.
