Presonus Studio Channel

VCA-based compressor and three-band parametric EQ

Studio Channel is a professional channel-strip consisting of Class A tube pre-amp, VCA-based compressor and three-band parametric EQ that can be used in professional and project studios. Ideal for all types of microphones, instruments, keyboards and synths, Studio Channel has the sonic power and flexibility to capture the tone of your dreams – be it delicious vocals, crystal clear acoustic guitars, punchy basses, dynamic pianos, punchy basses.

Studio Channel is noticeably better than the preamps found in many mid-range mixers and sound cards. Adding a VCA-based compressor and studio-quality EQ on top of the Class-A Tube pre-amp gives you not only wide and big tube sound, but precise control over your sound. Since recordings are usually channel-by-channel, you need a signal path that will allow you to capture a wide variety of sounds and tones while recording, which is why Studio Channel is the ideal device for any studio.

Studio Channel has everything you need to get a wide soundstage. The pre-amp solid is inspired by the award-winning BlueTube pre-amp. Working with a high output 12AX7 tube operating at twice the voltage of its competitors in its class, Studio Channel provides extremely high headroom and wide sound. Thanks to the dual gain control and Tube drive adjustment, any sound can be achieved, from a completely “transparent” sound to an “overdrive” sound.

Compressor in Studio Channel; It is a variable, ultra-fast and smooth VCA-based compressor with all kinds of compressor settings such as ratio, treshold, attack, release and gain make-up. VCA-based compressors are known for their musicality and ultra-fast attack time that can capture even the fastest transients. From slap bass to snare drum, vocals and piano, Studio Channel’s compressor lets you record any recording at the highest level possible, with full control over your dynamics without distortion.

The EQ in Studio Channel is like a Swiss army knife, you can easily eliminate unwanted frequencies and make fine adjustments to give your recordings the tone you want. Custom amps on the EQ circuit provide extreme musical gain/cut, allowing you to achieve silky highs, deep and powerful bass and crystal clear mids. The width around the selected frequency can be adjusted with the variable Q setting in the mid-band of the EQ section.
