Presonus Tubepre V2 Single-Channel Tube Preamplifier/Di Box $129.95 The masters at PreSonus have been designing preamps for a long time, and they always focus on audio quality first and foremost. Now theyve upgraded on their most popular single-channel preamp, the TubePre v2 is focused on improving an already high-quality sound. 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.The TubePre v2 provides an even wider palette of sound options, and a much more focused tube saturation than the original TubePre. It has been upgraded to employ PreSonus popular XMAX Class A solid-state preamp, which is followed in the signal path by a 12AX7 vacuum-tube stage. Twist the TubePre v2 Drive saturation control to add the color that only a hand-selected 12AX7 vacuum tube can deliver from gentle warmth to total fuzz.Housed in a rugged case, the TubePre v2 rear panel sports separate unbalanced 1/4 instrument and balanced XLR mic inputs and unbalanced 1/4 and balanced XLR line outputs. Plenty of professional extras including a high-pass filter, phantom power for condenser mics, polarity reverse switch and a backlit VU meter.The TubePre v2 is more than a mic preamp, though. Thanks to its separate instrument and mic inputs, it also serves as a dynamite direct box (DI) for guitars and basses. And its small enough to carry almost anywhere, although you also can screw-mount it to a standard rack tray.XMAX Class A preamp input stage12AX7 Dual-servo vacuum tube output stageInput Gain control48V Phantom power80 Hz High-pass filter-20 dB PadInstrument input selectPolarity-reverse switchBacklit VU meterClip LED1 Unbalanced instrument input1 Balanced XLR mic input1 Unbalanced line output1 Balanced XLR line outputCompact 1/3U rack-mount chassisExternal 12 VDC, 1A power supply |

Presonus Bluetube Dp V2 2-Channel Mic/Instrument Tube Preamp $229.95 The PreSonus name is synonymous with quality and performance in any studio, and they continue to build on that reputation with the BlueTube DP v2, a 2-channel tube preamp with PreSonus popular Class A XMAX preamps, which have been widely acclaimed for both their clarity and transparency. PreSonus tube preamps are known for their warm, smooth sound. With the Blue Tube DP dual-path mic/instrument preamp, you get both types of high-quality sound in one unit.The BlueTube DP v2 is an improvement on the classic BlueTube DP preamp. The solid-state path now feeds PreSonus pure Class A XMAX mic preamplifier with 80dB of variable gainan upgrade from the original BlueTube DPs solid-state stage. The tube path features a 12AX7 tube, which operates on voltages double that of other preamplifiers in its class, producing lots of headroom and big tone. BlueTube DP v2 offers lower noise, more high-end clarity, and an even smoother tube sound than its predecessor.You still get all the secondary features you expect in a professional-grade preamp: 48V phantom power, an 80Hz high-pass filter, -20dB pad to control hot input signals, and a polarity-reverse switch. Each channel has an illuminated VU meter so you can visually monitor your input levels.A Tube Drive control provides a wide range of sounds: when its clicked off, youre using the solid-state preamp for quiet, transparent amplification; when its engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion.Versatile and AffordableWith two combo mic/instrument inputs, the half-rackspace BlueTube DP v2 is a great choice for guitars and basses as well as for vocals. 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. It also serves as a DI box, thanks to balanced XLR and unbalanced 1/4 outputs, and is housed in a new, rugged, 1/2U case. Try the BlueTube DP v2 as a front end for a DAW, too; sure, your recording interface might already include preamps, but few of them give you both tube and solid-state operation.We have also updated the preamps compact, rugged enclosure; it has more rounded edges and looks modern and sleek. It can be used as a desktop unit or it can be screw-mounted to a standard rack tray.Dual path mic/instrument tube preampHigh-headroom Class A XMAX mic preamplifier with 80dB gain range12AX7 Vacuum tube gain stageTube Drive tube-saturation control48V Phantom power80Hz High-pass filter-20dB Pad to reduce hot input levelsPolarity-reverse switchIlluminated analog VU input-level meter2 Balanced combo mic/unbalanced instrument inputs2 Balanced XLR main (L/R) line outputs2 Unbalanced main (L/R) line outputsCompact 1/2U chassisExternal 12 VDC, 1A power supply |

Used Presonus Adl 600 Stereo High Voltage Tube Microphone Preamp $2001.95 The PreSonus ADL 600 is a high-voltage, 2-channel microphone preamp designed by world-renowned analog tube circuit designer Anthony DeMaria. It utilizes a Class A discrete design with 3 vacuum tubes per channel for maximum headroom and tonality.Control and FlexibilityThe ADL 600 is designed for supreme sonic performance and flexibility with XLR microphone/line inputs and 1/4" instrument inputs. The input selector allows for selection between Hi-Z instrument input, line input, and 4 different mic impedances for a number of applications. The rotary High Pass Filter switch has 3 settings (40Hz, 80Hz, and 120Hz @ 6dB per octave) for controlling room rumble and low-frequency noise. The input gain attenuator delivers 5dB-step increments and a total gain of over 72dB. The output stage is controlled by a variable conductive plastic attenuator that delivers +/-10dB of fine tune trim adjustment to dial-in the perfect gain structure for the application at hand. The ADL 600 also includes 48V phantom power and a -20dB pad. Under the HoodThere are no op-amps or integrated circuits (IC's) in the signal path to ensure the purest sound possible. The dual-transformer design guarantees ultralow-noise operation with maximum common mode rejection.MeteringThe ADL 600 is loaded with both fast-acting 8-segment LED meters for accurately detecting fast transients and peaks, as well as large analog VU meters for metering output level.ComponentsThe overall approach to the ADL 600's design was to keep the signal path as simple as possible by keeping the component count to a minimum. The few components that are in the signal path were chosen for their sonic qualities: custom audio transformers, polyfilm pulse capacitors, 1% metal film resistors, and conductive plastic potentiometers. Also, rotary switches and fixed 1% metal film resistors are used in the preamp gain circuit to keep noise to a minimum and to prevent any coloration that may be caused by a potentiometer.The custom-designed input transformer is fully encased in a Mumetal enclosure, yielding excellent noise characteristics and magnetic shielding. The transformer interfaces the balanced mic/line inputs to the tube preamp circuits. On the primary side of the transformer are circuits for +48V phantom power, microphone impedance, 20dB pad, and line input. All of these are switched by sealed relays for reliability. Also, the relays are located at the point where the switching is required. This minimizes the signal path length and helps to keep noise low.The combination of a 12AT7A tube and a 6922 tube form the principle gain stage, giving the ADL 600 its open and airy sound. This is primarily due to the circuit topology and the wide power supply rails applied to this stage--+/-320VDC. A high endurance Grayhill rotary switch and 1% metal film resistors are used to set the gain in 5dB steps. Polyfilm pulse capacitors are used for interstage coupling to maintain stunning clarity.
