ART

Tube preamp with optical limiter, S/PDIF, and USB connectivity.

The ART USBDualTubePre is a compact, dual-channel tube preamp designed for any basic recording system. Capable of operating as a standalone unit with USB audio interface, or as an expander for any digital system with S/PDIF digital input, each channel in the USBDualTubePre delivers superior tube tone in a fully featured input strip.

Each input of the USBDualTubePre has independent input gain control and output level, phase inversion, low frequency roll-off, true 48V phantom power, and a user-defeatable optocompressor circuit—capable of ensuring superior dynamic control of any input source.

For monitoring, an 1/8" mini headphone jack with level and monitor mix controls allow latency-free monitoring of the inputs while recording, as well as playback monitoring of audio mix via USB bus. The monitor mix is also routed to 1/4" TRS (balanced) outputs with separate level control for control room monitor source.

The USB interface is fully USB compliant. No special drivers are needed.

Great little utility recording box!

| Review By: Brian Skipworth | 3 months, 4 weeks ago

0 people out of 0 found this review helpful

Features:

A surprising number of features packed into this teeny little box. It's amazing the puzzle assembled by the circuit board and frontpanel designers. It helps to have small fingers when pressing the small, tightly-spaced buttons, but that's a direct result of the feature set.

Quality:

Feels sturdy, especially for Chinese factory-made product.

Value:

Astoundingly cheap for the huge list of features and respectable sound quality.

Overall:

This box is exactly what I needed to expand a little practice space recording rig. We have a pair of MXL pencil condensers on a stereo bar over the drums and they run to the Dual Pre then into the S/PDIF input on an old M-Audio Firewire interface. The drums come through clear and my drummer is happy he can hear every nuance of his fills.

 

This is a very solid, smartly conceived and executed product. Well done ART. Well done.

Better Than A Swiss Army Knife

Overall:
ART has done it again.    This amazing company always seems to know what my needs are.   I'm sure many others  must have the same requirements.     This handy device does just about all necessary front end audio tasks in a very compact portable unit.  It's stereo or two track mono with digital and analog outputs as well as having a USB interface.     The only notable LACK is a digital input and there's no EQ.     Those aren?t  as essential and  EQ can be done in post production.      I wish these Dual USB Tube Pre's were around years ago.     If you have any audio device that must be fed into any type of input,  this is the unit to do the job.   It  has tube circuitry,  phasing, low cut filters,  switchable monitoring  and a limiter.   WOW,    what more could you ask.      To  begin to answer that question you need to understand that this is a Swiss Army Knife type tool and isn't intended to be  in the same league as high end components.    Having said that,    it sounds great and is very quiet.    When you're on the go or have limited rack space,  this will be way more than adequate.    The interface USB is only 16bit but that is still absolute CD quality.  Again, this is a problem solver and by far out-weighs  any minor technical performance limitations. I also come across some compatibility issues which my be from something I didn't execute properly when setting up.    The S/PDIF output didn't get recognized by three of the four interfaces I have.    It does work quite well with my Tascam US 800 which is the one I need to use with it anyway.  I just want you to be aware that I'm being candid here.    Also, the first time I connected with my Vista desk top computer,   My DAW  only responded to a signal on one channel.    If these are red flags for you,  you need to investigate more fully.     I usually suspect human error  (my own),  before I pass judgment.         After all is considered,  I highly recommend   the ART USB  Dual tube preamp.
