Over the past 20 years the Ashdown ABM range has become the industry standard for bass players in pursuit of real bass tone, versatility, power and tour proven reliability. Now in its fifth incarnation, ABM EVO IV pairs class-leading pre amp sophistication with up-rated powerhouse performance and an all-new 9-band EQ. \u003cbr\u003e\u003cbr\u003eLovingly built and engineered the ABM 600 Dual VU Rack head is made for the road. The 3U rack chassis is fabricated from 2mm mild steel, with front and rear mounts to ensure your head can easily be racked and protected when travelling. \u003cbr\u003e\u003cbr\u003eDual VU Meters allow monitoring on the input gain as well as output level. \u003cbr\u003eThe ABM DUAL VU RACK EVO IV head teams the legendary ABM preamp with a gut-rumbling 600W power stage which will see you through any show when paired with the right cabinets\/s. \u003cbr\u003e\u003cbr\u003eVariable Valve Drive Plus - from zero to rock hero! \u003cbr\u003eOur Variable Valve Drive preamp section has also been upgraded in EVO IV. Delivering more current to the 12AX7 tube enables more drive and harmonic content than ever before, enabling players to dial in a sound from pristine clean, to the fattest, fullest bass overdrive currently available. The Drive level can be preset and kicked in and out via footswitch, providing access to a huge range of clean, warm and overdriven tones. \u003cbr\u003e\u003cbr\u003eThe best EQ in the business, just got better! \u003cbr\u003eBassists plugging into EVO IV will be greeted straight away by the flickering of the new Input VU meter, allowing them to quickly find the sweet spot for their instrument. From there, EVO IV features a sophisticated 9-band EQ, with familiar Bass, Middle and Treble controls and six sliders providing precision cut and boost at 100Hz, 180Hz, 340Hz, 1.3KHz, 2.6KHz and 5KHz. The EQ can be switched in via footswitch taking the player from a flat fretless sound to their favourite EQ setting instantly. The NEW 9-band EQ is a revelation of sonic perfection and will surprise older ABM users. \u003cbr\u003e\u003cbr\u003eOne knob compressor \u003cbr\u003eOther ABM favourite features are retained in EVO IV, including Ashdown's famous One Knob Dynamic Compressor sub octave note for huge bass tones. Kick it in and this simple to use, great sounding compressor delivers a powerful, even sound, guaranteed to help your bass fill out any mix. \u003cbr\u003e\u003cbr\u003eSub-Harmonic Generator \u003cbr\u003eOnce heard - never forgotten. The ABM Sub-Harmonic generator adds an octave below the notes being played bringing fullness to any bass part. The Sub level is independently controllable, letting you dial in anything from a subtle hint of deep bass to a full-on subterranean funk. \u003cbr\u003e\u003cbr\u003eProfessional Connections \u003cbr\u003eNot that you'd expect any less, ABM is loaded with connectivity. A tuner output, Line out, transparent FX loop and a Line Input for the connection of an external sampler or sound source. Output muting cuts the signal from the DI output but leaves the tuner output ?live', allowing the player to tune up in silence.\u003cbr\u003e\u003cbr\u003eFlexible Footswitching \u003cbr\u003ePaired with our FS-4 footswitch (not included) the ABM comes alive for onstage use, enabling on-the-fly tonal gearshifts. With footswitchable Valve Drive, Compression, EQ and Sub Harmonic Generator, ABM puts dozens of sound combinations at your feet, without so much as an effect pedal in sight. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eSPECIFICATIONS\u003c\/b\u003e\u003cbr\u003ePower Output: 600 Watts\u003cbr\u003ePower Requirement: 115-230 Volts\u003cbr\u003eSpeaker Outputs: 4 x Jack\/Speakon outputs\u003cbr\u003eFrequency Response: -3dB @ 17Hz und 30KHz\u003cbr\u003eHigh Instrument Input: Impedance 3.9m Ohms, input range 150mV\u003cbr\u003eLow Instrument Input: Impedance 10k Ohms, input range 300mV - 40V p-p\u003cbr\u003eLine Input: Impedance 22k Ohms, input level 0dBu nominal\u003cbr\u003eDI Output: 600 Ohm balanced, Level 0dBu nominal\u003cbr\u003eTuner Output: Impedance 22k Ohms, Level 0dBu nominal\u003cbr\u003eImpedance: Minimum 4 Ohms Per Side \u003cbr\u003eEffects Send: Impedance 22k Ohm, Level 0dBu nominal\u003cbr\u003eEffects Return: Impedance 22k Ohms, Input Level 0dBu Nominal\u003cbr\u003ePreamp Tubes: 1 x 12AX7\u003cbr\u003eDimensions (H x W x D): 139 x 457 x 304 mm\u003cbr\u003eWeight: 10.5 kg\u003c\/p\u003e","brand":"Ashdown Engineering","offers":[{"title":"Default Title","offer_id":47043740434646,"sku":"ABM600DR-EVO-IV","price":2299.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/3980\/files\/lg_1_1_761557.webp?v=1752173052","url":"https:\/\/www.lamusic.com\/products\/ashdown-engineering-abm-evo-iv-dual-vu-rack-head-abm600dr-evo-iv","provider":"L.A.
