- 1 - GBE 60 0 SIX HUNDRED D ESIGN PHILOSOPHY With many years of experience designing and manufacturing both bass guitar speaker cabinets and a m- plifiers, it became obvious that there is a large market for a bass amplifier line that reproduces the nat u- ral tone of the instrument itself, while allowing for personalization of tonal texture.
- 2 - TECHNICAL INFORMATION The first stage of the GBE - 600 preamp uses a low noise bi - fet linear scaling amplifier with a 2 pole low cut point at 23 Hz to prevent excessive speaker cone excursion and intermodulation distortion. Add i- tional bandwidth roll - off is provided at 20 kHz for RFI suppression.
- 3 - With the switch in the active position, the preamp presents a lower gain and input impedance which is tailored to active pickups . An active pickup is, for all practical discussions, any pickup that uses pre - amplification between the pickup element and the amplifier input.
- 4 - Tuner Output Jack — The “ tuner output jack” is provided to allow a tuner to remain plugged into the amplifier while playing. Thi s output remains active when the “ mute switch” is pressed, allowing for tuning your instrument while not sending signal to eithe r the “ direct output” or the speaker.
- 5 - Fan Switch — The GBE - 600 is a fan cooled high powered rack mount device. A 2 speed rear panel mounted “ fan switch” is provided t o allow the reduction of fan speed and corresponding fan noise during recording and low power playing.
