TUBEULTRAGAIN

Tube Microphone/Line Preamplifier

T1953

s Ultra low-noise discrete microphone/line preamplifier with selected 12AX7 tubes

s ULTRA-TUBE circuitry (UTC) adds desired amount of warmth without additional noise

s Mic input stages are based on high quality, discrete conjugate transistor pair circuitry

s Ultra-wide bandwidth from 18 Hz to 30 kHz for open sound

s Warmth control allows precise dosage of desired tube effect

s Completely versatile DI-Box due to servo-balanced inputs and outputs

s Level converter from -10 dBV to +4 dBu

s Soft mute +48 V phantom power to avoid switch-on thumps

s Fully tunable and switchable 12dB high-pass filter

s Switchable phase reverse to correct phase problems

s Ultra low-noise 4580 audio operational amplifiers offer outstanding sound performance

s Highly accurate metering with true RMS level detection

s Servo-balanced gold-plated XLR and 1/4" TRS inputs and outputs

s High-quality detented potentiometers and switches with vintage-style knobs

s Huge back-lit analog VU meters and stylish retro design

s BEHRINGERs high-performance OT-1 output transformer retrofitable
