Grezza 1 Posted July 11, 2022 Share Posted July 11, 2022 (edited) Carvin B2000 Black Bass Amp Fully Working and Excellent Condition. Absolutely amazing bass Head, with plenty of options and settings. In fully working order and great condition comes with power cable. Details from Carvin's Website: The mighty B2000 mono block head has been called the "King" of bass amps for one reason - its massive 2050 watts. Its style offers the classic boutique look that in part comes from the large brass knurled chrome knobs, which offer a solid feeling when using the controls. Featured in a 19" 2U rack mount package weighing under 14 pounds, the days of 80 lbs amps are over. But more then power, it’s the big tone this amp produces from its CLASS A preamp, 6 active EQs and warm 12AX7 tube. The B2000's light weight, premium features, rugged construction, including the exclusive "lock-in" AC cord, offer the bass player what he/she needs to be heard and felt. Nothing provides a better foundation than the B2000 - huge power and big tone. High Headroom Tube Driven Power Amp The high output B2000 produces 700w RMS at 8 ohms, 1300w at 4 ohms or 2050w at 2 ohms. The B2000 uses three different transparent limiters to maintain its high headroom to assure ultra clean power even with extreme string slapping. For added warmth, take advantage of the internal 12AX7 TUBE that utilizes two stages that precede the power amp section. Drive Control The DRIVE control adjusts the input level to the CLASS A preamps and compensates for the input sensitivity of various bass pickups. The DRIVE will add harmonic content to your sound when approaching 10 on the dial, which pushes the CLASS A preamps into a sweet overdrive. Dedicated Tone Circuits Tone begins with a boutique flat response. However, the 6 active tone circuits are available to carve out your signature sound, starting with the SUB BASS. Its simple yet powerful controls make it easy to dial in your idealized tone without fussing with lots of knobs. Direct Output The direct out features a DI LEVEL control and PRE/POST switch on the rear panel controlling the XLR balanced output on the rear. The PRE setting is buffered directly from the first stages of the preamp to the XLR. The POST setting includes the EQ and EFFECTS LOOP, bypassing the MASTER LEVEL. This enables level changes without affecting the XLR output. The XLR is muted by the MUTE switch. The GROUND LIFT switch next to XLR helps isolate hum to the recording or PA console. B2000 Features - MASTER level controls the overall level - ACTIVE/PASSIVE switch tailors the input for different bass outputs - MUTE switch can be engaged for quick bass changes, which is also controlled by the optional FS22 footswitch - TUNER output jack is independent of the MUTE switch - EFFECTS LOOP is designed to work with footpedals or rack processors, and is switchable from the front panel or from the optional FS22 footswitch - SPEAKER OUTPUTS feature high current SPEAKON™ combo jacks, which also accept standard 1/4" cables - 94% efficient CLASS D output delivers high current for continuous 2 ohm operation and is cool running, plus uses less AC power from the wall - Switch mode power supply operates at 90,000 Hz delivering maximum efficiency while reducing heat and weight - Variable speed fan runs silently while at low speeds - Construction features solid metal shaft controls with threaded metal bushings - Circuit boards are MIL SPEC, double sided, FR-4 glass epoxy - Exclusive AC cord features a "lock-in" function to prevent accidental cord disconnect - Designed and built by Carvin in the USA Specifications: OUTPUT POWER: 8 Ohms: 700w, 4 Ohms: 1300w, 2 Ohms: 2050w - OUTPUT MODE: high efficiency CLASS D technology - POWER SUPPLY: high frequency switching - REQUENCY RESPONSE: +/- 1 dB 20 Hz - 20 kHz amplifier section - DAMPING FACTOR: >300 - PREAMP: 3 stage CLASS A - PREAMP TUBE: 12AX7 switchable in/out - INPUT IMPEDANCE: >200Kohms - ACTIVE/PASSIVE Input Jack: 10 dB gain switch - accommodates all basses - ACTIVE TONE CONTROLS: +/-12dB @ 40Hz, 100Hz, 400Hz, 800Hz, 2kHz, 6kHz - DI OUT with Pre/Post swtich: -50 to +4 dBu adjustable, DC isolated XLR output - EFFECT LOOP: -10dBV, buffered - SOFT START: gradually turns the amp on to prevent surges that can trip circuit breakers - PROTECTION: speakers, over current, under voltage and thermal - AC VOLTAGE: 120V 60Hz (230V 50 Hz "-E" models available) - Power Requirements: 600VA - DIMENSIONS: 2U rackmount, 19" wide x 10.5" x deep 3.5" high - NET WEIGHT: 14 lbs net (5.2 kgs) - MADE IN THE USA Edited July 14, 2022 by Grezza 1 2 Link to comment Share on other sites More sharing options...
Dan Dare Posted July 11, 2022 Share Posted July 11, 2022 Nice. I have a B1000. Strictly speaking, it's my spare, but it's so good, I sometimes take it out in preference to my AG700. The preamp is excellent, especially after I fitted a slightly less gainy 12AX7. Have to admit to being tempted. GLWTS 1 Link to comment Share on other sites More sharing options...
Grezza 1 Posted July 11, 2022 Author Share Posted July 11, 2022 Hi Dan thanks I totally agree I’ve got an SWR rig as my spare but really not sure whether to move that on instead and keep this ! You could always make me an offer if you’re interested cheers Graham Link to comment Share on other sites More sharing options...
