2 Channel Tube Mic Preamp


The TPS II (Tube Preamp System 2) is a two channel high performance preamplifier coupled with ART’s proprietary V3™ (Variable Valve Voicing) functionality. With variable valve voicing, the TPS II is completely versatile and maintains a high quality of performance you would expect from an ART tube preamp. The TPS II also features variable input impedance which allows users to dial in and match any microphone type from large condensers to ribbon mics.

Like it’s predecessor, the DPS, our newly improved V3 feature provides optimized reference points to begin the recording process for guitars, bass guitars, synths, acoustic instruments, percussion, vocals and more. Unique to its’ class, the TPS II provides level monitoring with two analog meters as well as two newly added input monitoring LED meters. High-Z instruments or balanced microphone signals are input through front and rear panel jacks.

This newly enhanced TPS II can accept +20 dB peaks while maintaining over 120 dB dynamic range, quiet performance and incredibly low distortion.

ART’s legendary tube stage maintains our classic “warm sound” and adds additional tube voicing specifically tailored to vocal, guitar, bass, and acoustic instruments making the TPS II an incredible DI box. Our OPL™ (Output Protection Limiting) feature is also included to control overshoots and normalize levels before clipping occurs.

The TPS II was conceived, designed and manufactured to the highest standards to provide years of quiet, reliable performance. Audition one, and you too will know why the TPS II is indeed the most cost effective professional mic preamp system you’ll find on the market today.
