DI/O Preamp System

The ART DPS (DI/O Preamp System) represents a true breakthrough in quality tube microphone preamplification with digital conversion. The combination of great features, stellar audio quality and the incredibly affordable price of the DPS are simply outstanding.

The DPS features two channels of high performance discrete preamplification and are coupled with ART's proprietary V3™ (Variable Valve Voicing) 12AX7A gain stage. The DPS also offers a choice of both analog and digital outputs. Enhancements to our legendary tube stage maintain our classic "warm sound." The new enhanced mic preamp design can accept +20dB peaks while maintaining over 120dB dynamic range and incredibly low distortion.

V3™ delivers multiple tube voicings specifically tailored to voice, guitar, bass, synths and acoustic instruments. This powerful processor is an incredible microphone preamplifier and DI box.

Our OPL™ Output Protection Limiter is available to control overshoots and normalize levels before digital clipping occurs.

High-Z instruments or balanced microphone signals are input through front and rear panel jacks. Unique to its' class, the unit provides level monitoring via two analog meters.

The Digital Section of the DPS: The digital outputs of the DPS include S/PDIF, TOSLINK or ADAT (front panel selectable). The A/D is front panel adjustable from 44.1 to 96K, or syncs to ADAT or external word clock (32KHZ to 100KHz).

You can patch into any ADAT stream and select which pair (or all) of channels the DPS transmits. A versatile insert loop on each channel provides access for additional signal processing or direct access to our high quality A/D converter. Separate gain controls on analog and digital outputs allow you to optimize the unit for simultaneous applications. The DPS was conceived, designed and manufactured to the highest standards to provide years of quiet, reliable performance.
