SPL Gold Mike Tube Preamp

The Gold-Mike is another jewel in the SPL Tube series. Like all SPL tube processors, it combines the unique sonic qualities of tube technology with state-of-the-art manufacturing, meticulous component selection and high-tech conception. The technical standards are predicated on an uncompromising effort to combine the sonic advantages of tube technology with modern semi-conductor amplification design, allowing for up to 72 dB of gain - a value that tube-only designed preamps simply cannot match. The Gold-Mike's whisper quiet performance makes it ideal for digital recording and even the most demanding recording subjects, such as choirs, are easily handled. The Class A tube amp, designed as two independent mono blocks, guarantees absolute channel separation and stereo recordings in particular will benefit from a wider stereo depth. Features include: Spl's unique "FLAIR" circuitry, which enhances the presence and intelligibility of any signal. Vocals, for example, seem to move closer. Other features include a 50Hz high-pass filter, phase reverse switch, 30 dB pad, switchable 48-volt phantom power with independently filtered power supply, high-quality ALPS potentiometers, click-free switches, five LEDs per channel, two backlit VU meters, Warm-up LED indicates tube status during warm up, Star ground wiring scheme for best sound performance, extra wide PCB ground connections guarantee stable voltage distribution, Power supply with state-of-the-art filtering schemes and solid power reserves (6000 µF in the main supply and 400 µF in the tube supply), XLR inputs, XLR and 1/4" outputs (can be used individually or simultaneously).
