SIGNAL LED: Indicates the presence of an instrument signal at the tube stage. -10 db SWITCH: Lowers the BASSBASE'S input impedance (e.g. for active instruments). DIRECT: Press this button to send the original instrument signal (unaffected by gain settings, voicing controls, FX loop and notch filter) directly to the DI OUT jack, at MIC level. GROUND LIFT: Removes the ground from the chassis at the DI OUT jack. I,/’ ,_‘. ,/,’ GRND DIR 0 0 -10 dB 0 CLIP LED: Indicates all types of clipping in the BASSBASE’s preamp (including post-EQ section and FX loop distortion). In other words, an illuminated CLIP LED does not necessarily mean the GAIN control is set too high, it may also indicate the FX signal level is not adjusted properly. MUTE: Switches all of the BASSBASE 400’s outputs except for the TUNER OUT off. Use this button for breaks between sets, switching instruments, or when tuning. The RED MUTE LED will illuminate to indicate the amp is muted. DI OUT: Use this jack to send signals to a mixing console or additional power amp. INPUT Connect your bass to this jack. CAIN: Controls the input sensitivity and drive level of the BASSBASE preamp. 0 10 -5 -5 +5 -15 +15 BASS: This EQ control defines the bottom end. At the 12 o’clock position, the signal remains completely unaffected. TREBLE: Use this control to adjust the high end, particularly the sizzle and overtone range. FREQ HZ LEVEL dB t FREQ HZ: Defines the center frequency for the VARIMETRIC EQ's LOW RANGE section. Please refer to Section 3.2! LEVEL: This control adjusts the level of the frequency you selected via the FREQ HZ control. Turn clockwise to increase, counter-clockwise to decrease. BASSBASE 400 -MANUAL Red VARIMETRIC LED: Illuminates to indicate the VARIMETRIC EQ is active. FX LOOP ON: Press this button to activate the EBASSBASE 400’s VARIMETRIC ON: Activates the VARIMETRIC EQ. , DYNACLIP LED: Illuminates when the DYNACLIP power amp circuit is active. DYNACLIP eliminates undesirable power amp distortion and provides 20% additional headroom in comparison with conventional power amps. PROTECT LED: Illuminates when one of the power amp circuit breakers has tripped. Inadequate ventilation, a short circuit in the SPEAKER OUTS or direct current in the output will trigger the circuit breaker. TEMP LED: Indicates that thermal overload (overheating) is the reason why the protective circuit has activated (e.g. when the ribbed ventilation duct is obstructed). -MAINS: AC power switch. MAINS PHONES parallel FX loop Green FX LED: Indicates the FX loop is active. NOTCH FILTER: This adjustable, extremely narrow-band filter is not used for normal sound- shaping, but to suppress specific stage and room resonances (e.g. a stage floor’s sympathetic vibrations). FREQ KHZ LEVEL dB FREQ HZ CUT dB FREQ: Use this control to adjust the notch filter’s center frequency within a range of 30 to 500 Hz. LEVEL: T s control adjusts the level of the center frequency you selected via the FREQ KHZ control. MASTER: Controls I the BASSBASE 400’s PHONES: Plug headphones overall output. with an impedance rating within the 4-600 ohm range into this jack. FX-MIX : The FX MIX pot adjusts the balance between the original signal and the processed signal. DRY = original signal only, WET = processed signal only. FREQ KHZ: Defines the center CUT: Turn this control up to suppress the frequency for the EQ's HI frequency you selected via the FREQ RANGE section. control. BASSBASE 400 -MANUAL REAR PANEL: FOOTSWITCH VARIMETRIC: Connect a standard single-channel footswitch to this jack. If you use a HUGHES & KETTNER FS-1, its LED will illuminate when you activate the VARIMETRIC EQ. TUNER OUT: Output jack for an external tuning device. I FOOTSWITCH FX LOOP: Connect a standard single- channel footswitch to this jack. If you use a HUGHES & KETTNER FS-1, its LED will illuminate when you activate the FX LOOP. LINE OUT: The full-range signal from this jack can be sent to a mixing console or additional power amp. RETURN: Connect this jack to the FX processor’s OUTPUT jack. - 10 db SWITCH: Press this damping switch to lower the signal level sent to the input of effects processors expecting an instrument-level signal such as stomp boxes. ‘t I MAINS SOCKET: Connect the included power cable (Euronorm) to this socket. The fuse bracket is integrated in the socket; make certain you use specified replacement fuses only! SEND: Connect this jack to the FX processor’s INPUT jack. SPEAKER OUTPUTS: Output jacks for connecting external bass speaker cabinets (these jacks are wired in parallel). The overall impedance rating is 4 ohms. For instance, you can connect one 500 watt cabinet with a minimum rating of 4 ohms or two 500 watt cabinets with a minimum rating of 8 ohms each. If you operate the BASSBASE 400 at a higher impedance rating, power output will decrease accordingly. It is very important that you heed the maximum rated handling capacity of any speaker cabinets you choose to connect, especially if you have borrowed ...
