Radial J33: Bring Your Turntable Into the Studio The Radial J33 is an active stereo turntable phono preamp and DI box, delivering +37.8 dB of RIAA-corrected gain and balanced XLR outputs. It accepts a moving-magnet turntable on stereo RCA inputs and presents both mic-level XLR and consumer-level RCA outputs, so a record player can feed a recording interface, a mixing console, or a hi-fi receiver. For anyone who wants to move a vinyl collection into the digital world without losing its warmth, it is the missing link between the platter and the DAW. Why a Turntable Needs a Phono Preamp A turntable cannot plug straight into most modern gear, and there is a specific reason why. When a record is cut, the bass is deliberately reduced and the treble boosted following the RIAA curve, a standard pre-emphasis that keeps low frequencies from cutting grooves too wide and pushes surface noise up where it can be filtered out. A phono preamp does two jobs to undo this: it applies the exact inverse RIAA de-emphasis to restore a flat, natural frequency balance, and it adds roughly 37 dB of gain to lift the tiny output of a phono cartridge up to a usable line level. Skip that stage and vinyl sounds thin, quiet, and harsh. The RIAA Curve and 47 Kilohm Cartridge Loading Accurate playback depends on loading the cartridge correctly. The J33 is designed for moving-magnet cartridges and presents the industry-standard 47 kilohm input load they are built to see, which sets the high-frequency response and keeps the top end from ringing or rolling off. Its precision RIAA de-emphasis network then reverses the record-cutting curve across the audio band, so what reaches your outputs is the flat, full-range signal the recording engineer originally mastered, not the pre-emphasized version pressed into the groove. Balanced XLR and Consumer RCA Outputs The J33 speaks two languages at once. A pair of balanced XLR outputs delivers a mic-level signal that plugs into a mixing console or an interface's mic preamp exactly like a microphone, only in stereo, which is ideal for recording and archiving. At the same time, a pair of -10 dB consumer-level RCA outputs feeds a home stereo receiver or powered speakers directly. You can record and monitor through a hi-fi system from the same box without repatching. A Switchable Rumble Filter Tames Low-End Noise Vinyl carries more than music in its lowest octaves. Warped records, motor rumble, and footfalls all produce subsonic energy that eats headroom and makes woofers pump. The J33 includes a switchable rumble filter, a high-pass that rolls away this inaudible low-frequency noise while leaving the musical bass intact. Engaged during archiving, it keeps a digital transfer clean and prevents subsonic garbage from wasting bits or overloading a converter. Clean Conversion: 0.002% THD and 91 dB Dynamic Range Archiving is only as good as the preamp doing the work. The J33's active circuit posts just 0.002% total harmonic distortion and a 91 dB dynamic range, numbers that mean the preamp adds essentially no coloration or hiss of its own to the transfer. That transparency matters most when you are digitizing an irreplaceable record: the goal is to capture exactly what is in the groove, and the J33's low noise floor and low distortion keep the copy faithful to the source. Dual Power: 48V Phantom or the Included 15V Supply The J33 gives you two ways to power it. When it is connected to a console or interface, it can draw standard 48V phantom power right down the XLR cable, so no extra outlet is needed on stage or in a rack. For hi-fi and desktop use where phantom power is not available, it runs from the included 15V DC supply. Either way a rear earth/ground terminal lets you bond the turntable's ground wire to eliminate the hum that plagues phono setups. Where the J33 Fits Your Setup The most common job is archiving and digitizing vinyl to a DAW, taking the balanced XLR outputs into an interface to preserve a record collection before the pressings degrade further. It is equally at home connecting a turntable to gear that has no phono input, adding proper RIAA correction and gain to any line-level device. And for DJs, it lets a turntable plug into a mixing console or PA over balanced lines, delivering clean, hum-free stereo wherever the record needs to play.
