    Product Description

    The ART Tube PAC 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 tabletop 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.
