TPS II
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 manu-
factured 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.
