A. INPUT - Plug your bass in here. B. 6dB - Reduces input sensitivity to allow cleaner response with high-output bass guitars: NORMALFull input sensitivity. 6dBLower input sensitivity. C. VOLUME - Adjusts the preamp signal level. Use together with MASTER {P} to set the overall loudness of the amplifier. CLIPIndicates preamp clipping. Occasional flashing is normal when you play hard. Reduce VOLUME level if you hear distortion when this LED is on. PRE AMP SIGNALIndicates sufficient signal strength. Turn up your instrument or the VOLUME level if this LED is off when playing. D. COMPRESSOR RATIO - Typically used to even out a musical performance, a compressor provides a smoothing effect between thumb and fingerstyle type attack. The compressor control on a Bassman series amplifier determines the compressor RATIO. When a signal is loud enough to enable the compressor to come on, the RATIO determines how THICK the compression will be. When turned all of the way down, the RATIO is 1:1 (off), as you turn the control up, the RATIO increases (2:1, 3:1, 4:1) and the sound of the compression becomes more noticeable. The ideal setting for compression is almost inaudible to the ear, but satisfying to the fingers (a sense of control over the instrument).
E. ROOM BALANCE - Room Balance is for the player to dial in the room as a final touch of EQ. This feature is OFF when in the center position (start the EQ process with this control centered; dial it in last). Turning the control clockwise emphasizes highs, while de-emphasizing lows (great if the stage sound is dark and muddy). Turing the control counterclockwise creates the opposite effect; emphasizing lows while de-emphasizing highs (helps with bright hardwood floors). This frees up the EQ of the amp to design your TONE instead of compensating for poor room acoustics. F. CONTOUR - This feature is for scooping out the mid-range signal, a sound typically desired for thumb style playing to achieve a modern hi-fi type bass tone. Turning this knob clock-wise increases the cut of the mid range, increasing the scooped sound. G. BASS - Adjusts low-frequency tone character. H. 2-BAND SEMI-PARAMETRIC EQ - Having more control over the mid-range frequencies is very important in defining your bass tone. This is why your Bassman comes equipped with semi-parametric control (1 band on the Bassman 100, 2 bands on the Bassman 150 & 250). The Frequency knob is there to determine WHERE you would like to adjust the sound. Level is there to determine whether you would like that particular frequency to be boosted or cut (+/-15 dB). Adding upper mids (and favoring the bridge pickup on your instrument) creates a biting tone that is great for Jazz Fusion type melodic lines. Cutting mids allows for separation between the lows and highs, resulting in a tone well suited for slapstyle funk. I. TREBLE - Adjusts high-frequency tone character.

7 J. FX BLEND - Adjusts the amount of effects loop wet signal mixed with the dry signal. K. PRE/POST - Supplies the LINE OUT {N} jack with the signal either before or after it is processed by the amplifiers equalization/tone circuits. PREEQ bypassed POSTEQ active L. LINE LEVEL - Adjusts the output level of the LINE OUT jack {N}. M. GROUND LIFT - Disconnects the LINE OUT {N} ground connection (pin-1) which may reduce hum noise in some situations. GROUNDED (normal) GROUND LIFTED N. LINE OUT - This jack allows you to send signal from the preamp section out to an external source (such as a house mixing console or a recording device). The on board level control allows for adjustment of signal strength. Use the Pre/Post control to select if you would prefer the bass signal to be affected by the EQ changes you make (post) or before the EQ, to give an unaffected signal (pre). The Ground Lift is there to eliminate buzz resulting from connection to improperly grounded equipment. O. MUTE - Disables all amplifier outputs except for TUNER OUT {X}. The LED flashes when MUTE is active. P. MASTER - Adjusts the power amp signal level. Use together with VOLUME {C} to set the overall loudness of the amplifier. PWR AMP CLIPIndicates power amp clipping. Reduce MASTER level if you hear distortion when this LED is on. Q. POWER - Switches the amplifier on-off. Illuminates when the unit is powered on.

Rear Panel

S. IEC POWER SOCKET Connect the included power cord to a grounded AC receptacle in compliance with the voltage and frequency ratings specified on the rear panel of your amplifier. T. PARALLEL SPEAKER OUTPUTS - Use the 1/4" phone jacks and Speakon connector in any combination to connect a total speaker load of 4ohms minimum. Combo units have a 4-ohm internal speaker load for maximum power output. The following configurations are recommended: One 4ohm speaker Two 8ohm speakers V. AUX IN - RCA input jacks for connecting your drum machine or CD/tape player. Control the level of this input at its source. W. EFFECTS - (1) Effects Loop - Connect SEND to the input of your effects device and the output of the effects device to RETURN. (2) Multiple Amplifiers Connect SEND on the primary unit to RETURN on the auxiliary unit. The primary unit controls all auxiliary units except MASTER. X. TUNER OUT - Connection for your bass tuner. Use MUTE {O} for silent tune-ups. Y. HORN LEVEL (combo units only) Adjusts the volume level of the horn.

MIN. MAX.

FUSE 2A 250V
U. HEADPHONES - Connect your headphones here. Disconnect speaker connections for private listening.
Z. FUSE - (combo units only) Protects the horn from overload damage. If the horn stops responding, replace the fuse with the same type and rating as specified on your amplifier (F2A, 250V).
