Presonus STUDIO CHANNEL 1 Ch Vacuum Tube Ch Strip Mic/Instrument Preamplifier
We named this channel strip the Studio Channel, and indeed it’s a wonderful studio tool. But it’s great for live performance, too. Featuring tube preamplification, a VCA-based compressor, and three-band EQ, it delivers a huge variety of timbres. Produce luscious, in-your-face vocals, dynamic acoustic piano, and fat, solid bass guitar, not to mention crystal-clear acoustic guitars and cracking snare. Yes, we got the name wrong; we should have called it the Anywhere Channel. But we got the design right.
Impressive headroom and a huge variety of fat sounds.
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.
Fast, smooth, musical VCA compression.
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.
Sweet three-band EQ—before or after the compressor.
The three-band equalizer in the Studio Channel is a precision tool, with the ability to carve out unwanted frequencies as well as tailor your tone to enhance your sound. The EQ can be pre- or post-compressor, and you can bypass each stage independently. Custom-designed amplifiers deliver sweet-sounding gain and cut for smooth highs; deep, solid lows; and clear midrange. The midrange band is fully parametric, with variable Q, while the high- and low-frequency bands are semi-parametric, with Frequency and Gain controls but fixed Q, and can be either shelving or peak bands.
Tasty spices that work with virtually everything.
In the lunch room at PreSonus’® Baton Rouge headquarters, it’s an article of faith that Cajun spices taste great with almost everything. The Studio Channel is equally versatile, delivering great sound for virtually any type of recording or live music. And with separate XLR mic, balanced ¼-inch line, and unbalanced ¼-inch instrument inputs and balanced XLR and ¼-inch outputs, you can connect it to almost any recording interface, amp, or P.A. This really is an Anywhere Channel! Hear it for yourself at your favorite PreSonus dealer.
