ART Tube Pac Mic Preamp

The Tube PAC from ART is a combination of the world's most popular tube mic/line preamplifier and optical tube compressor. ART engineers took the Tube MP and Tube Compressor and combined them into a single convenient aircraft-quality, extruded aluminum chassis. This new table-top design allows for easy placement in the studio or on the stage, with immediate access to all the controls, features, and metering. In addition to being a tremendous vocal and instrument preamplifier and compressor package, this may well be the ultimate in tube direct boxes.

The mic/line preamplifier stage is that of the TEC nominated Tube MP-a time (and studio) proven design. It provides over 70dB of gain, +48v phantom power, phase reversal, and is capable of warming up any instrument or microphone. LED level indicators are provided to monitor the output of a 12AX7a tube for harmonic content. The input level controls allows you to dial in the desired amount of tube warmth and then independently set the output level from the compressor circuitry.

The tube compressor is a VCA-less, optical design-similar to that of the classic tube compressors. Its ultra-musical sound is ideal for voice and instrument applications. Threshold, compression/limiting ratios, adjustable release times, bypass, gain reduction metering, and output gain controls are provided.

The Tube PAC is another impressive package from the world-wide leaders in tube dynamics signal-processing gear.

Customer Reviews
4 out of 5 (77 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. This review has been selected by our experts as particularly helpful. ART Tube Pac Mic Preamp Customer Review
Sound: This sounds pretty nice. Warmer and fatter than my DMP3 or Mackie pre's. I mainly got it as a bass DI for recording, then found it sounds nice with an AT2020 mic for vocals, and nice as an acoustic guitar pre for live use. Feature: Would have liked more flexibility in the compressor section, but it does alright with the "pre-sets"... Ease of Use: Super easy...plug it in and go. Again, it would have been better if the comp had more adjustability, but the settings it has make it kind of a no-brainer! Quality: I don't know here. The first one I got worked 5 minutes, then crapped out. I got a replacement, and in the meantime fiddled with the first one. Took it apart, pulled out the tubes, put them back, and now it works fine. I guess maybe the tubes weren't seated well in their sockets? We'll never know, but it works fine now. Value: Seems like a nice sounding unit for the price, especially noting the various uses I've found for these. Manufacturer Support: Don't know, never tried them! The Wow Factor: Its just something I needed, gets the job done, nothing more! Overall: For the money, nice. I've got the two now, and don't plan on getting rid of them anytime soon. They work, they sound good, and until I can kick $2000 for something REALLY Nice, I'll keep working with these.

"Good sound, good value, good preamp."
Sound: Much cleaner than I expected. Made my voice sound a bit better than I thought it would. Feature: I haven't even played around with the compressor settings yet, as much as I would like, but so far so good. Even though there's only three knobs to play with, there's plenty of variety. Quality: Feels sturdy and heavy. The knobs seem very reliable and click just right. Completely satisfied. Value: For slightly over 100 bucks, there's no reason not to get one if you are serious about getting a good, professional mic preamp. Manufacturer Support: Haven't dealt with any yet, but oh well. Overall: I like it. What can I say.
Style of Music: soft rock
