The AEA RPQ with Curve Shaping and P48 power puts all the controls for ribbon mics at your fingertips: 80 dB of clean quiet JFET gain, P48 phantom power for active studio ribbons such as AEA’s A440, and LF trim and HF boost contols that are tuneable and defeatable so that you can tame proximity problems and/or add a little more to the top. The RPQ has the speed, quietness, and headroom needed for high resolution ribbon recordings, and it sounds good with condenser and moving coil mics. AEA’s DC-coupled JFET topology delivers all the dynamics, subwoofer bass and fast transients that your ribbon and other mics are capable of. Its discrete front end and integrated circuit architecture meld the quietness of solid state with an openness reminiscent of tubes. Live and location recording is another area where the RPQ shines. Its Low-Energy-Storage (LES™) circuitry recovers instantly from overloads, a big advantage with unpredicatable dynamics, and its exceptional No Load™ input impedance of over 10,000 Ω makes it an ideal active mic splitter. Mic splits usually load down, changing a mic’s sound, but not the RPQ.RPQ Electronics Specifications80 dB of gain at 1 kHz, balanced-in to balanced-outNoise figure A-weighted Frequency response -3 dB 200 kHzBalanced mic input impedance >10 kΩDC-coupled inputs protected from external P48 DCAC-coupled inputs with switchable P48 phantom powerTwelve position stepped gain control from 7 to 55 dBTrim gain continuously adjustable from 0 to +19 dBSwitched LF trim: -3dB points tuneable from 18 to 350 HzSwitched HF boost peak +6 dB at 12 noon, +16 dB maxHF max boost +3dB points tuneable from 2 to 18 kHzXLR out has 6 dB gain, balanced or unbalanced loadXLR max output+28 balanced, +22 unbalanced, 600 Ω¼” TRS max output unbalanced +22 dBu, 100 kΩ loadPin 2 high on XLRs, tip high on ¼” TRS jacksGreen LED snaps on at ~ -5 dBu, Red at ~ +20 dBuYellow LED brightens from ~ 0 to +20 dBuRPQ Physical DetailsP48 Phantom & Polarity-Reverse pushbutton switchesRotary potentionmeters (pots) detented at 12 noonGrayhill series 71 stepped gain switch and trim potLF Cut pushbutton switch and one potHF Boost pushbutton switch and two potsPushbutton power switch, LED power indicatorInternal torroidal transformer with linear regulatorsMale recessed IEC power plugLaser engraved front panel markingsMetalic blue and steel gray powder coat finishAluminum and steel chassisClear coated polished aluminum end capsDetachable polished aluminum rack earsChassis: 17.25” wide, 11” deep, by 1.7” highMetric: 44 cm wide, 28 cm deep, by 4.3 highWeight: 6.75 pounds, Metric: 3.1 KgSpecifications as of Oct. 1, 2008, subject to change Link: Wes Dooley, founder of AEA, talks about Studio Mic Pre Standards in the 50’s
