Transparent solid-state, warm tube distortion, and everything in between.

With the BlueTube DP V2 dual-path preamp, you get the best of two worlds. Our popular Class A XMAX solid-state preamps are widely lauded for their clarity and transparency, delivering incredibly high headroom, deep lows, smooth highs, and a rich overall sound.

Singer-songwriters can run their vocal through one channel and their guitar through the other, feeding both to the P.A.—no guitar amp needed. And we didn’t forget the extras: an 80 Hz highpass filter, phantom power, a -20 dB pad to control hot input signals, polarity reverse, and a backlit VU meter.

So when we decided to upgrade our popular TubePre V2, we focused on improving an already high-quality soundwithout jacking up the price. Like the original TubePre, the new version is a fully professional tube preamp, with a dual-servo (no capacitors) gain stage that lets you boost the program signal to smoking hot levels without significantly increasing the background noise. Discrete components and high-voltage operation offer dynamic range and detail not found in other single-channel tube preamps in its class. All Rockville pro audio cablesare made with 100% copper which boosts the efficiency of the cable. There isnothing better than 100% copper. Most of the cheaper cables on the market do notuse 100% copper, instead they make their cables with CCA (Copper Clad Aluminum).CCA cables do not perform on the level that 100% copper cables perform at. CCAwill not conduct signals efficiently. A 12 gauge CCA cable will not even performas well as a 14 gauge 100% pure copper cable, which will in turn.

The XMAX preamplifier runs on power rails of 30V. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound.
