Smooth, big, musical...those are three words we would instantly associate with what this tube pre can do for your mics! Designed with famed tube-circuit designer Anthony DeMaria, the ADL 600 employs a distinctive Class A, discrete design with three top-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 separate mic, line, and instrument inputs, and you can select among four mic-input The ADL 600’s 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 eight 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, polarity inversion, 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. Hearing is Believing 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. 2 input channels, each with: Mic, line, and instrument inputs High-voltage, Class A, dual-transformer, vacuum-tube preamp 3 military-grade vacuum tubes Input-source select Variable mic-input impedance (150, 300, 900, 1,500Ω) Variable high-pass filter (40, 80, 120 Hz) 8-position Gain switch Variable Trim adjustment for final stage 48V phantom power -20 dB pad Polarity-reverse switch Backlit VU meter (output level) with -6 dB switch (for metering hot signals) > 73 dB of gain Input/Output 2 unbalanced ¼” instrument inputs (front panel) 2 transformer-balanced XLR line inputs 2 transformer-balanced XLR mic inputs 2 transformer-balanced XLR line outputs Physical 2U 19” rack-mountable, rugged steel chassis Internal power supply with standard IEC connector Chassis-ground link connectors (lift chassis ground)


Thoughts on Presonus ADL 600

ADL600 is a great preamp. Excellent on vocals.

Gear Porn thread - pics of your slutty setups

I am quite amazed about my Lake People converters. And with the wonderful ADL 600 Preamp, it looks nice. The second pic is my babe grand Yamaha C7 with Neumann KM184 and Apex 205 (Michael Joly Mod)

Best dynamic mics

Did you ever tried this combination MD441 and ADL600 for saxophone ? Sounds insanely good. Another candidat which I really love is the old Beyerdynamic Soundstar MK2 N400, also known as the poor mans SM7B.
