500 Series EQ

Dangerous Music didn’t bring BAX to the 500-series until it could be done with zero compromise. BAX500 follows the same core design principles as the rackmount BAX EQ, using identical exacting components selected for both performance and sound, and tested to draconian tolerances to ensure consistency, reliability, and long-term stability.The Broad BAX500 shelves shape several octaves at once, allowing small adjustments to unlock depth, sheen, and weight without pinching the sound or introducing phase incoherence or harshness. Where narrow, surgical EQs excel at solving problems, BAX500 is designed to make musical decisions—revealing what’s already there rather than imposing a new character.High Cut and Low Cut filters with smooth, natural slopes remove infrasonic rumble and ultrasonic interference that quietly eat headroom, smear transients, and reduce clarity. By cleaning up the extremes before further processing, BAX500 helps mixes translate more easily while preserving openness and punch.The signal path is DC-coupled up to the Low Cut filter and features a relay-controlled hard-wired bypass that physically removes the circuit from the signal path for true A/B comparisons. The steel enclosure is fully shielded to protect against unwanted electromagnetic interference, and the laser-etched, paint-filled faceplate is designed to remain legible and durable over decades of use.

Console-grade EQ in a Compact ModuleTeeming with legendary Neve character, the 88R LBEQ packs four bands of parametric, console-style EQ into a convenient 500 Series module. The Neve 88R LBC is patterned after the topology of the large-format 88RS console, yielding a sublime combination of high-precision transparency and high-impact tone shaping. From subtle enhancement to intricate frequency surgery, you’ll value this module’s console-grade flexibility, melding ±20 dB gain per band, extensive frequency overlap, and smoothly adjustable Q. Moreover, the 88R LBEQ’s musical response, nonexistent phase shift, and broad headroom rival that of its large-format predecessor. Boasting the same sonic pedigree trusted and employed by such iconic facilities as Abbey Road, AIR Studios, and The Village, the 88R LBEQ brings elite-class tone-sculpting capabilities to modern hybrid studios seeking both legendary Neve sonics and the power, headroom, and control modern engineers demand.Precision EQ with a revered pedigreeThe Neve 88RS console stands as one of the brand’s crowning achievements, revered for its sonic accuracy, aural transparency, and muscular punch. Built around the same precision topology as the 88RS, the 88R LBEQ packs the same sonic wallop as the venerated large-format console, reimagined as a compact 500 Series module. And it does so without compromise, delivering over +27dBu of headroom, greater than 107dB dynamic range, and ultra-low distortion of less than 0.004%. Moreover, it draws less than 145mA RMS while maintaining optimal headroom and transient response. With the 88R LBEQ, you’ll gain access to the same authoritative character found in the world’s top studios, such as Abbey Road, Air Studios, and The Village.Neve: the legend continuesAt Sweetwater, the name Neve commands reverence. Rupert Neve started designing audio equipment in the tube console era but made his mark with solid-state designs. Setting up shop in Little Shelford in the ’60s, Mr. Neve faced many obstacles establishing his brand amid a new technological landscape. Transistors were new, expensive, and difficult to obtain in quantity in the UK. Reliable faders didn’t exist yet — a far cry from today’s world, where parts are affordable and readily available from multiple suppliers, all competing to win bids. Nevertheless, Rupert persisted. And by the early 1970s, the Neve company was humming along, taking orders and building custom transformer-balanced consoles for recording and broadcast studios the world over.Neve 80-series consoles had a huge, punchy, and authoritative sound that defined the sound of ’70s rock. From London to New York to Los Angeles and beyond, top studios were installing Neve desks as fast as they could. By 1978, with the introduction of the majestic 8078 — the pinnacle of handwired analog “production” consoles — and NECAM automation system, Neve boards were the main component of the success formula for any recording studio with world-class aspirations. In the decades since, Neve has innovated with groundbreaking products such as the VR, VX, and 88R series consoles. And today, the company continues to advance the state of the art with cutting-edge pro audio gear that sounds incredible and intelligently addresses the challenges of the digital age.Neve 88R LBEQ Features:Packs console-style EQ into a convenient 500 Series moduleNeve 88RS-style topology yields a sublime combination of high-precision transparency and high-impact punch4 bands of parametric EQ tackle subtle enhancement and intricate frequency surgery with equal aplombDelivers ±20 dB gain per band, extensive frequency overlap, and smoothly adjustable QMusical response, nonexistent phase shift, and broad headroom rival that of the full-sized 88RS consoleHandcrafted in England using premium components and calibrated in house

They're classic SSL parametric mid-bands capable of the traditional SSL processing techniques but also go far beyond, offering absolute surgical precision all the way to creative 'notch' style filtering and resonant screaming. Focus modeFocus mode allows users to ‘hone in’ on problem frequencies or specific frequencies they want to accentuate or attenuate. Pressing the ‘Focus’ switch in, automatically narrows the chosen Q setting further and increases the range of gain available beyond the normal +/-9 dB operation, to a huge +/-18 dB. In true flexible SSL workflow fashion, it transforms this sweet sounding, musical SSL EQ into a more surgical tool.HPF & TrimRemove rumble and tighten up low frequencies, the HPF found on UV EQ brings a world of flexibility when processing low end. The interaction with LF shelving band offers unique ways to sculpt signals and yes, UV EQ is capable of the sought after boost + cut effect. Dedicated Trim control means you can hit convertors with plenty of headroom or smash into them the perfect amount when clipping is desired.

Loved by Generations of Professional ProducersThe E-Series EQ 500 series module reproduces the legendary sonic signature of an early 80's classic, the equaliser section of the Solid State Logic SL 4000 E console channel strip, which has featured on countless classic recordings from the 1980's to the present and shows no sign of stopping. The 611 design E-Series EQ also feature on Solid State Logic's latest audio production console, ORIGIN. FeaturesImmortal SSL 4000 E Series circuitry"Black-242" and "Brown-02" twin EQ designVersatile 4 band channel EQBell curve option on HF and LFFully parametric LMF and HMF with QBased on classic 611E console channel stripUnique response & tonal characterThe E-Series EQ Module features two different EQ's found on editions of the console produced between 1981 and 1989. Each EQ has unique response curves and tonal character. Historically the type of EQ fitted in an individual console was distinguished by the colours used on the LF knob caps so the two flavours have become known as the 'Brown' and 'Black' EQ's. On the E Series EQ Module you can switch between these two different flavours of EQ that have been loved by generations of professional producers.

Το API 550 EQ έπαιξε σημαντικό ρόλο στην ιστορία της μουσικής ηχογράφησης στις ΗΠΑ κατά τη διάρκεια της δεκαετίας του '60 και του '70. Αρχικά δημιουργήθηκε για χρήση στις API κονσόλες, η πιο πρόσφατη έκδοση του 550, το «Β», είναι η εξέλιξη του αρχικού μοντελου 550 του 1967, μέσω του 550A, με πρόσθετο filter band και διάφορες νέες συχνότητες. Ενσωματώνει την αποκλειστική διάταξη κυκλωμάτων και τα εξαρτήματα του API (όπως του θρυλικού API 2520 op-amp), το 550B συνδυάζει επιδέξια το παρελθόν με το παρόν. Πολλές επιτυχίες στηρίζονται ακόμα στο μοναδικό 550 ήχο. Πολλά EQ προσφέρουν σήμερα μια τεράστια ποικιλία  περίπλοκων χαρακτηριστικών γνωρισμάτων, αλλά το API 550B παρέχει ακριβώς το σωστό αριθμό ρυθμίσεων στον επαγγελματία ηχολήπτη. Το 550B θα είναι ένα ανεκτίμητο εργαλείο που θα χρησιμοποιήσετε επανειλημμένως.

Λίγοι ισοσταθμιστες απολαμβάνουν το σεβασμό και το θαυμασμό του API 550A. Σχεδιασμένο από τον πλέον θρυλικό Saul Walker στο τέλος της δεκαετίας του '60, το 550A αρχικά χρησιμοποιήθηκε ως modular ισοσταθμιστείς OEM. Καθώς η βιομηχανία ασπάστηκε γρήγορα την sonic ποιότητα του 550A, βρέθηκε πολύ γρήγορα σε πολλά  custom μοντέλα κονσόλων του Frank DeMedio και άλλων κορυφαίων δημιουργών. Πολλές από αυτές τις κονσόλες είναι ακόμα και σήμερα σε λειτουργία. Σαράντα χρόνια αργότερα το 550A παραμένει το πρότυπο με βάση του οποίου όλα  τα αλλά EQ κρίνονται, και έχει παίξει πολύ σημαντικό ρόλο στη βιομηχανία της ηχογράφησης για δεκαετίες.        ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ 3 bands of classic API equalizationEach band offers 5 API selected frequency centersReciprocal and repeatable filteringmaximum 12 dB of boost/cut per bandEQ Band 1 and 3 offer shelf/peak switching"Proportional Q" narrows filter Q at extremesTraditional API fully discrete circuit designHigh headroom +30 dB clip level
