The ART Pro Audio Tube PAC Preamplifier/Compressor is a combination of the TEC nominated Tube MP, a tube mic/line preamplifier, and the Levelar, an optical tube compressor. This new 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, the unit also functions as an excellent tube direct box.
The mic/line preamplifier stage of the Tube PAC 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 allow the user to dial in the desired amount of tube warmth and then independently set the output level from the compressor circuitry.
The tube compressor on the Tube PAC 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.
