plifiers, it became obvious that there is a large market for a bass amplifier line that reproduces the natu-
ral tone of the instrument itself, while allowing for personalization of tonal texture.
As with our speakers, Genz Benz amplifiers strive to maximize your instrument's natural tone and feeling
without imparting additional coloration or reducing impact and playability. This results will always be true
to your instrument's basic natural qualities and your personal tonal signature.
The circuit design, features and physical construction have been carefully calculated to give you, the ex-
perienced player, the best performance and value in bass guitar amplification. Featuring sturdy jacks and
controls, solid state preamp and shaping filters, 5 band active EQ, a balanced direct output and an in-
dustrial duty bipolar power amplifier with toroidal power transformer, the Genz Benz GBE 400 bass am-
plifier gives you the tools and versatility necessary to sound your very best on stage.

TECHNICAL INFORMATION The first stage of the GBE 400 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. Addi- tional bandwidth roll-off is provided at 20 kHz for RFI suppression. The variable gain stages are a feed- back-divider type control, providing a maximum gain of about 30 dB. - Page 3 (approximately 4KHz) of the signal, allowing exaggeration of per- cussive effects and string sound. Active 5 Band Equalization — The “active 5 band equalization” used in the GBE 400 amplifiers is com- posed of 1 shelving low frequency control, 3 peaking midrange controls and 1 shelving high frequency control.
