The Studio V3 offers all of the features of the original Tube MP with versatile onboard presets to easily dial in a great tone. V3 stands for Variable Valve Voicing, and refers to the sixteen presets in three overlapping groups: Neutral, Warm, and OPL. Each has a precisely voiced EQ curve, Warm presets add tube saturation, and OPL presets engage Output Protection Limiting for dynamic control of loud signals and big transients.Each preset has a suggested application, but they all have a unique character, so any could be an inspiring match for your performance. Theres also a Flat preset for the classic sound of the original Tube MP. Like the original, the Tube MP Studio V3 has XLR and 1/4 connections with variable gain and switchable boost, phantom power, and phase reversal. Fast and flexible, the Tube MP Studio V3 is a mic preamp and instrument DI designed for maximum tone with minimum tweaking.Main Features:Provides Superior Preamplification for: Microphones, Instruments and Line Level SourcesV3 Variable Valve VoicingOPL Output Protection LimitingHand Selected 12AX7A Provides 70dB of Gain Smooth, Warm and Fat Sound QualityVariable Input and Output Gain ControlsExcellent as a Tube DIXLR and 1/4 Inputs and Outputs+48 Volts of Phantom PowerPhase Reversal SwitchPortable, All Steel ConstructionSpecifications:Inputs: XLR (Balanced), 1/4″ TSOutputs: XLR (Balanced), 1/4″ TSInput Impedance: 2k XLR,, 840k 1/4Output Impedance: 600 XLR, 300 Maximum Input Level: +14 dBu XLR, +22 dBu 1/4″Maximum Output Level: +14 dBu XLR, +22 dBu 1/4″Maximum Gain: 50 dB – 60 dBFrequency Response: 10 Hz to 30 kHz, +/-.5 dBTotal Harmonic Distortion: <0.1% (typical)Equivalent Input Noise: -129 dBu to - 105dBuCMRR: >75 dB (Typical @ 1 kHz)Power Requirements: SA 9 VAC @ .8A (Typical) Export Units Configured for Country of DestinationDimensions: 5.0 x 5.5 x 2.0 (12.7 cm x 13.97 cm x 5.1 cm)Weight: 1.5 lbs / 3.3 kg
