Product Description Product Specs/Additional Information Related Videos Audio Product Description The Bullhead 3K represents the pinnacle of our design ethos to create powerful, intuitive, flexible tools to help bassists achieve their creative and sonic goals. We wanted to offer players an amp with unparalleled power, headroom and dynamic range, and a completely revolutionary approach to signal routing and input/output flexibility. The result is a unique and groundbreaking bass head that meets the needs of the most discerning and imaginative professional players. In addition to the remarkable clarity, warmth, and fidelity of the Bullhead 3K’s award-winning Mike Pope-designed preamplifier and 4-band switchable EQ, the 3K’s dual Pascal power amplifiers deliver an unrivaled payload of wattage and precision that is musical, crystal clear, and effortlessly fast.DUAL INPUTS AND OUTPUTS The 3K’s front and rear inputs feed the dual amplifiers in several intuitive and flexible ways, depending on how you intend to use the amp. They offer two independent or linkable power channels, each delivering 1500w x2 at 8 ohms (2500w at x2 4 ohms). They can be easily configured to run two completely independent rigs side by side or sum the front input to both amplifiers.The 3K’s front input (Input 1) feeds the iconic Mike Pope-designed Trickfish preamp, which includes our 4-band switchable EQ. The rear input (Input 2) features a separate Gain and Master Volume on the top right of the front panel. With the “Amp 2” switch engaged, Output 2 becomes independent of Output 1, effectively creating two high-powered bass amps in one.HIGH PASS/LOW PASS FILTERS On the top left of the front panel, you will find the 3K’s defeatable, variable High Pass and Low Pass filters for Output 1 (or for both outputs when they are summed from Input 1). When engaged, they provide a steep 24dB per octave cut, below (HPF) or above (LPF) the frequencies you desire. This allows complete control over the total “width” of the 3K’s frequency range. The High Pass can be set to tame the low end anywhere between 38Hz and 310Hz, while the Low Pass can be set to reduce treble content starting at 15kHz, all the way down to 330Hz. These precise filters allow you to tailor the incredibly wide and full range bandwidth of the 3k, to pocket your sound in whatever sonic region you desire, while keeping the overall tone or character of your sound completely intact. Product Specs/Additional Information Input – This jack can be used to connect an instrument via a standard 1/4″ mono cableInput Attenuator – A switchable input attenuator offers 0dB or -10dB settings, accommodating both high-output active and lower-output passive instrumentsHigh Pass Filter – Eliminate unwanted bass frequencies using a steep 24dB/octave filter, adjustable from 38Hz to 3kHzLow Pass Filter – Soften piercing highs with a customizable 24dB/octave filter, tunable from 330Hz to 15kHzBass Cut/Boost with Frequency Select – Shape your low-end with a ±12dB shelving control, featuring a selectable starting point of either 40Hz or 80HzLow Mid Cut/Boost with Frequency Select – Fine-tune your low-midrange with a ±12dB bell-shaped EQ, centered at either 330Hz or 473HzHi Mid Cut/Boost with Frequency Select – Adjust your high-midrange using a ±12dB bell-shaped EQ, centered at either 1kHz or 1.8kHzTreble Cut/Boost with Frequency Select button – Tailor the high frequencies using a ±12dB treble shelf EQ, with starting points at either 4kHz or 8kHzMaster Volume – Controls the overall volume of main amplifier outputAmplifier Mute – Mutes the signal to the amplifierAmplifier 2 Gain & Master Volume – Controls the gain and master volume output for amplifier 2. Turning the switch to the “ON” position routes the signal of the rear amplifier 2 input to the amplifier 2 speaker outputPower Output (x2)4 Ohms: 2500W @ 0.05% THD 8 Ohms: 1500W @ 0.05% THD *RACK EARS INCLUDED AC Mains Input Connector – Attach supplied IEC power cable firmly into socket. Universal mains for 100V-240V operationSpeaker Output Main – Connect a speaker cable here for use of the main (amplifier 1) output. This Speakon combo jack allows for either Speakon or ¼” speaker cable operationSpeaker Output Amplifier 2 – Connect a speaker cable here for use of the amplifier 2 output. This Speakon combo jack allows for either Speakon or ¼” speaker cable operationAmplifier 2 Input with Phase Selector – This jack can be used to connect an external source via a standard 1/4″ mono cable. Connecting a source with the AMPLIFER 2 switch off will be mixed with the front input signal. With the switch to the amplifier 2 set to ON, the signal will be routed to the second power ampAmplifier 2 Direct Out with Ground Lift – Connect a balanced XLR cable to send the direct signal of amplifier 2 to a mixer, interface, or other input source. This DI also features a dedicated ground lift selectorAux Input – The Line In jack accepts a signal from a laptop, phone, MP3 player, or other input source. Connect headphones for silent practicing with the volume controlled by the master volume on the front of the ampTuner Output – This jack can be used to connect an tuner via a standard 1/4″ mono cableEFX Loop – SEND jack routes the signal TO the destination device. The RETURN jack returns the signal FROM the destination device. The series/parallel switch changes the EFX Loop from parallel operation to serial operation. The EFX loop also has a dedicated ground lift to eliminate unwanted humMain Direct Out – Connect a balanced XLR cable to send the direct signal to a mixer, interface, or other input source.
