Product Description

The ADL 600 is a high voltage two-channel original microphone preamplifier designed by world-renown analog tube circuit designer Anthony DeMaria. The ADL 600 utilizes a unique high voltage, Class A discrete design with three vacuum tubes per channel for maximum headroom and tonality. The ADL 600 is built by hand in the USA by PreSonus and utilizes the finest components in the world including switched attenuators, military-grade vacuum tubes, analog VU and LED meters, custom-designed proprietary transformers, and the list goes on. No expenses are spared with the ADL 600 down to the last polypropylene film capacitor. The ADL 600 is big, warm, smooth, and clear; a sound like no other.

Control and Flexibility

The ADL 600 is designed for ultimate sonic performance, however its ease of use and flexibility allowing for many types of input sources further sets it above all other preamplifiers. The input selector allows for selection between Hi-Z instrument input, line input and four different microphone impedances for a wide variety of sounds and applications. The high pass filter is a rotary switch with three filter settings (40Hz, 80Hz, and 120Hz @ 6dB per octave) for passively and unobtrusively controlling room rumble and low frequency noise. The input gain attenuator is a military-grade rotary switch delivering 5dB step increments and a total preamplifier gain of over 72dB. The output stage is controlled by a fully variable conductive plastic attenuator delivering +/-10dB of fine tune trim adjustment to "dial-in" the perfect gain structure for the application at hand. The ADL 600 also includes 48V phantom power and a -20dB pad both controlled by big sturdy military grade switches.

Under the Hood

The ADL 600 is built with the finest components available in the world. The ADL 600 is a fully discrete transformer input and output Class A design incorporating three military-grade vacuum tubes per channel operating at voltages of +/-300V power rails for maximum tube tonality and headroom. There are no op-amps or integrated circuits (IC's) in the signal path to ensure the purest sound possible. The dual transformer design also ensures ultra low noise operation with maximum common mode rejection.

Metering

The ADL 600 is loaded with both fast-acting eight-segment LED meters for accurately detecting fast transients and peaks, as well as large high quality analog VU meters for metering output level.

Breathtaking

The ADL 600 sets a new standard in tonatily for tube preamplifiers. Vocals become big, smooth and articulate, bass guitars are deep and tight, and mixes become richer than ever. The ADL 600 is breathtaking both in terms of appearance and in sound performance. The ADL 600 delivers a sound like no other.

Customer Reviews
5 out of 5 (19 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. ""Better Late Than Never""
Overall: It only took a few years before I finally pulled the trigger on this unit, ( I've done a lot of research and painstakingly tried a variety of pres) but, I'm glad I did! The unit arrived late this morning and I ran vocals and mic'd my acoustic guitar thru it this evening. Beautiful, warm tone..I couldn't be happier!I have a pair of Focusrite ISA One's that I dearly love and have used for quite some time ( I won't give 'em up). The ADL 600 just takes things to a different level and makes my sound a warmer and larger, especially if I do solo acoustic guitar.This unit is solid, heavy, powerful (like an old muscle car), but more importantly is the quality of sound it produces. I know some may think this pre is 'old-hat', but I know one thing. It sounds reaaally good. Isn't that what it's all about? Monet well spent! Period!It ain't cheap, but why settle for something less when it comes to making your music?
Style of Music: Varies with the mood.

zZounds has verified that this customer bought this product from us. "Is it a Dream"
Sound: First off I didn't think that I would ever be happy, and proud to say that I own a Line 6 PODxt. Until one day I brought home my ADL. When I ran my POD through this pre amp, I about died. It actually sounded like I was going through an actual cab. I also tried it on my Martin (acoustic) and I was floored with the brightness and tone that came out. Vocals were another, alive, and vibrant! The only thing that I was not truly happy with was none of my basses sounded beyond this world, great sound, but for some reason I still like my Robby for my basses. Lastly, running a mix back out through the ADL, was a very good decision, after rerecording back into my DAW, I use a Precision Limiter from U.A. and everything sounds perfect!!! Feature: Sleek, Elegant, Sharp, Mean, and just straight up BEAUTIFUL Ease of Use: SUPER EASY!! with having the analogue meters, you also have light meters that help you push the ADL into your compressor, and get the fullest tone that it can produce without going into too much distortion. Quality: Yes. Everything is sound, and sturdy. The knobs are strong yet very smooth. The trim nob seems a little too loose and fast, but it is very accurate with its movements. Last, the switches are very strong and durable. I don't think you would ever accidently bump into one and it would snap off! Value: It is a little pricey, but you DO get what you payed for! Manufacturer Support: Never had to deal with them. The Wow Factor: I think that if I could afford it, and after I get the other mic pre's that I want, I would definitely buy a second one. Overall: This Pre would ALWAYS be in my arsenal, I believe that ANY equipment can be used in something. Everything has its place, and so does the ADL.
Style of Music: Varies! The only thing that gives me a hard time is Country.
