Input
1. PASSIVE: This jack allows for the connection of a bass guitar with passive-pickups to the BMAX-T. 2. ACTIVE: This jack allows for the connection of a bass guitar with active-pickups to the BMAX-T. It is attenuated, with respect to the �passive input�, by about 6dB to allow for the higher level output of active-pickup systems.
Pre-amp
3. BRIGHT: The Bright Switch connects a capacitor to the GAIN circuit creating a 10dB boost @ 10Khz. 4. GAIN: This controls the output of the preamp section post EQ. 5. 3-BAND INTERACTVE EQUALIZER: The Bass and Treble controls are mainly �boost� and the Mid control only �cut�. While there is no absolutely flat position, the response is reasonably flat with the controls set at TREBLE:2, MID:10, BASS: 2, with the bright switch off. The circuit can be described as interacting, such that when all 3 tone controls are turned to 0 then no signal is passed at all.
Para-mids
6. FREQ: A range from 250hz to 1000hz is adjustable with the FREQ knob. 7. GAIN: This control is adjustable as follows: �0� = -12dB �5� = 0dB �10� = +12dB
