2-channel Tube Preamp with Mic/Line/Instrument Inputs, Variable Input Impedance, and Custom VU Meters.
The Groove Tubes SuPRE is a two-channel stereo microphone and instrument preamplifier that uses a high resolution tube signal path for legendary Groove Tubes tone and response. Like the ViPRE, it features variable transformer impedance settings on each channel (300/600/1200 ohms), with four high-quality Nickel core input and output transformers. The SuPRE provides a hefty 72dB of gain on each channel, using four specially selected GT pentode/triode dual element vacuum tubes (2xGT6922 dual triodes and 2x GT6CH8 pentode/triode tubes).
The Groove Tubes SuPRE Features: - Classic Groove Tubes sound from high-resolution tube signal path
- Variable transformer impedance settings on each channel
- High-quality Nickel core output transformers
- Mic and Line inputs on rear panel
- Instrument input on front panel
- 3-position attenuation: 0dB, 15dB, 30dB
- 75Hz high-pass filter
- 72dB gain on each channel
- Large, independently adjustable VU meters
The SuPRE's front panel packs in a lot of control features while remaining cleanly laid out and easy to use. An input selector selects between rear-panel Line or Mic inputs, while a front-panel Instrument input automatically overrides the rear panel jacks when an instrument is inserted. A 3-position attenuation switch drops mic levels, selectable at 0dB, 15dB, and 30dB, and 75Hz high-pass filtering are provided. SuPRE's +48V phantom power is available individually on each channel. Large custom rotary variable attenuators control gain over the available 72dB range. SuPRE's two large custom VU meters, each with individually adjustable range control, allow for 0Vu line-up with virtually any outboard gear.
