Description Technical Specs
The Groove Tubes Vipre is an all-tube, variable impedancemicrophone preamplifier with selectable
rise-time and VU meter ranges. It features extremely high bandwidth, low inter-stage feedback, very high gain, enormous dynamic range and graceful overload characteristics.

All-tube audio path – NO semiconductors, transistors,
ICs or electrolytic caps anywhere in the signal path.

Eight Groove Tube compliment:
4 x 6922 (6DJ8) – preamp and rise-time circuitry
1 x 12AT7 – output driver and rise-time circuitr y
1 x GT6205 – instrument input preamplification
2 x 6AQ5 – Class A push/pull output

Switch-selectable fully-floating differential input and
fully-floating differential output.

Switch-selectable variable-impedance input, steppedbetween 300-, 600-, 1200- and 2400-ohm taps off high-performance, custom-wound input transformers.

Switch-selectable rise-times.

Precise and repeatable gain settings, in 5dB and 1dB increments from 15dB to 75dB.

Precision audio metering facilities with expanded and peak views on a true VU meter.

Robust one watt (+30dBm) output.

Massive energy storage (>60 joules) in the high tension power supply.

DC-to-daylight bandwidth (4Hz >100kHz).

Hand-wired point-to-point connections using highest possible quality components and wires.

Custom-built ceramic deck attenuators.

Superior and stable audio performance under the
widest range of preamplifier applications.
