Tổng quan về Preamp PreSonus Studio Channel

The Studio Channel’s Class A preamplifier starts with a high-output 12AX7 tube that operates on voltages double that of other preamplifiers in its class. The result is lots of headroom and big tone. Gain and Tube Drive controls enable a wide range of sounds, from transparent and clear to edgy and overdriven. A -20 dB pad, 80 Hz highpass filter, and polarity reverse let you tweak your signals to sit properly in the mix.

Our VCA-based compressor is known for musicality and fast attack, with the ability to tame the fastest transients. From slap bass, to snare drum, to vocals, the Studio Channel’s compressor allows you to record blazing-hot signals with accurate dynamics control. In addition to ratio, threshold, attack, release and gain controls, it offers a convenient Auto Attack/Release feature with preset attack and release curves. The backlit VU meter can display gain reduction or output gain.
