Groove Tube GT55

The flat black GT55, the solid state version of the GT66, is a true Class A condenser microphone equipped with a 1.1-inch, hand-assembled and tested large-diameter capsule with an ultrathin 3-micron gold evaporated diaphragm. The GT55 has a cardioid polar pattern and warm Class A FET electronics. At the heart of the GT55 is a hand-assembled, hand-tested 1.1-inch diameter capsule. This 3-micron evaporated gold diaphragm with Disk Resonator technology provides amazing sensitivity that delivers a sparkling, transparent sound across the full frequency spectrum. The Groove Tubes' Disk Resonator technology gives the GT55 an extended frequency response ideal for accurately capturing the realism of just about any sound source. Large-diaphragm microphones often get bogged down resonating at low frequencies preventing them from efficiently reproducing frequencies above 14 kHz -15 kHz. Groove Tubes' Disk Resonator interacts at high frequencies with part of the diaphragm, extending the range of the capsule well beyond 20 kHz.
