BBE BMAX-T All-Analog Tube Bass PreAmp

BBE BMAX-T All-Analog Groove Tube Bass PreAmp Overview :

The all-analog BMAX-T is a Tube bass preamp with a Class-A,DC regulated tube preamp section which follows in the tradition of the classic tube preamp designs of the 50s and 60s.

Applications :

• Recording studio
• Live concerts

Features :

• High voltage (300V) tube front end with hand-picked 12AX7 tube, providing pre-amp gain and passive interactive tone control
• High-end DI section is transformerless
• 1% metal film resistors
• Military-spec PC board
• Custom-made toroidal power transformer

Specifications :

• Frequency response @ line out
• 15Hz to 30kHz ±3dB
• Signal to noise ratio
• 100dB @ unity
• Total harmonic distortion (THD)
• Tube section: 1%
• Post-tube section: less than 0.02%

Maximum output

• +22dBu
• Noise
• -77dBu @ unity gain, eq flat

Input impedance

• Passive: 1M Ohm
• Active: 100k Ohms

Output impedance

• Balanced XLR: 600 Ohms, pin #2 hot or “+”Unbalanced ¼”: 1k Ohms

Interactive EQ
