PreSonus ADL 600 2-channel High-Voltage Tube Microphone Preamplifier We make some very good tube preamps, and we are confident that you enjoy using them. But the ADL 600 is at another level. Rumor has it that some people are willing to sell their left eyeball to get one. And while we don’t accept eyeballs as payment, we do agree that the ADL 600 is the finest tube preamp money can buy. Not the finest for the price. The finest—period. Designed by famed tube-circuit designer Anthony DeMaria, the ADL 600 employs a distinctive Class A, discrete design with three military-grade vacuum tubes per channel, operating with ±300V power rails for maximum headroom and superb tone. The dual-transformer design also ensures low-noise operation, with maximum common-mode rejection. We use only the finest components, including switched attenuators, analog VU and LED meters, and custom-designed, proprietary transformers. There are no op-amps or ICs in the signal path. We went high-end all the way, right down to the last polypropylene film capacitor. The result is an ultra-low-noise tube preamp with a big, warm, smooth, clear, distinctive sound. It produces big, smooth, and articulate vocals; deep and tight bass guitars; and rich, full mixes. It makes virtually anything you run through it sound better. Maximum Flexibility Beyond superb sound quality, the ADL 600 is special because of its ease of use and flexibility. Each of the two input channels has mic, line, and instrument inputs, and you can select among four mic-input impedances, so the preamp works great with any type of microphone. The high-pass filter employs a rotary switch with three filter settings (40 Hz, 80 Hz, and 120 Hz at 6 dB/octave) for controlling room rumble and low-frequency noise. The input-gain attenuator is a military-grade rotary switch that provides 5 dB stepped increments and a total preamplifier gain of over 73 dB. The output stage is controlled by a fully variable attenuator that delivers ±10 dB of fine-tune trim adjustment, enabling you to dial in the perfect gain structure for any application. And of course, you get 48V phantom power and a 20 dB pad, controlled by big, sturdy, military-grade switches. We didn’t skimp on metering either. Fast-acting, eight-segment LED meters accurately detect fast transients and peaks. Large, backlit analog VU meters display output levels, and a -6 dB switch lets you meter particularly hot signals. Technical explanations are well and nice, but hearing is believing. Try the ADL 600 yourself and experience the thrill of using the world’s finest tube preamp. That will tell you all you need to know.
