{"product_id":"aea-trp3","title":"AEA TRP3","description":"\u003cdiv lang=\"en\"\u003e\n  \u003cp\u003e\u003cstrong\u003eAEA TRP3\u003c\/strong\u003e is a two-channel, third-generation microphone preamplifier in a half-rack chassis, designed for passive ribbon microphones. The Gen 3 circuit by Fred Forssell delivers 68 kΩ input impedance (phantom off) and a gain range of 7–85 dB with THD+N of 0.0015% at 30 dB gain — among the lowest distortion figures in this class of preamps. The TRP3 shares topology and sonic character with the RPQ3 but omits the EQ section in favor of a more compact, road-ready format.\u003c\/p\u003e\n\n  \u003ch3\u003e68 kΩ and 85 dB Gain — Purpose-Built for Passive Ribbons\u003c\/h3\u003e\n  \u003cp\u003ePassive ribbon microphones demand high input impedance and high clean gain simultaneously — two requirements that most standard preamps address poorly. The TRP3 presents 68 kΩ (phantom off), allowing passive ribbons to operate without the high-frequency loading loss that occurs with standard 1.5–2.5 kΩ preamp inputs. With phantom engaged, input impedance drops to 11.3 kΩ due to the feed resistors required for 48 V delivery; still several times higher than typical mic preamps and sufficient for condenser and dynamic sources. Bandwidth at full 85 dB gain reaches –3 dB at 9 Hz and above 200 kHz — the full transient and low-frequency content of any microphone passes through without restriction. Maximum output of +27 dBu into 600 Ω provides headroom for long cable runs to consoles or converters.\u003c\/p\u003e\n\n  \u003ch3\u003eHPF, Phantom and Portable Half-Rack Format\u003c\/h3\u003e\n  \u003cp\u003eThe switchable high-pass filter offers –3 dB at either 115 Hz or 230 Hz at 6 dB\/octave — effective for controlling proximity effect and mechanical rumble without touching an EQ insert later in the chain. The twelve-position gain switch (+7 to +65 dB) combined with a continuous output trim (0 to +20 dB) gives a total range of 7–85 dB with repeatable, session-to-session settings. Per-channel +48 V phantom power and polarity reverse are individually switchable. The lightweight aluminum half-rack body is designed for location recording and studio use alike: a single TRP3 mounts in 1U with optional rack ears; two units fit side by side in 1U with the optional rack shelf, keeping a matched stereo pair in a single rack space.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2-channel AEA Gen 3 mic preamp, half-rack format\u003c\/li\u003e\n    \u003cli\u003eInput impedance: 68 kΩ (phantom off) \/ 11.3 kΩ (phantom on)\u003c\/li\u003e\n    \u003cli\u003eGain range: 7–85 dB (12-position switch +7 to +65 dB + output trim 0–+20 dB)\u003c\/li\u003e\n    \u003cli\u003eTHD+N: 0.0015% (1 kHz, 22 Hz–22 kHz, 30 dB gain, +4 dBu output)\u003c\/li\u003e\n    \u003cli\u003eBandwidth (85 dB gain): –3 dB at 9 Hz and \u0026gt;200 kHz\u003c\/li\u003e\n    \u003cli\u003eMax output level: +27 dBu (600 Ω load)\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 50 Ω\u003c\/li\u003e\n    \u003cli\u003eMax input level: +20 dBu (minimum gain)\u003c\/li\u003e\n    \u003cli\u003eHPF: –3 dB at 115 Hz or 230 Hz (switchable, 6 dB\/oct)\u003c\/li\u003e\n    \u003cli\u003e+48 V phantom power per channel (switchable)\u003c\/li\u003e\n    \u003cli\u003ePolarity reverse per channel\u003c\/li\u003e\n    \u003cli\u003eExternal switching PSU (included)\u003c\/li\u003e\n    \u003cli\u003eOptional accessories: rack ears (1 unit in 1U) and rack shelf (2 units in 1U)\u003c\/li\u003e\n    \u003cli\u003eHandmade in Pasadena, California, USA\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eChannels: 2\u003c\/li\u003e\n    \u003cli\u003eFormat: half-rack, 1U (with optional rack ears)\u003c\/li\u003e\n    \u003cli\u003eInput impedance: 68 kΩ (phantom off) \/ 11.3 kΩ (phantom on)\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 50 Ω\u003c\/li\u003e\n    \u003cli\u003eGain range: 7 dB – 85 dB\u003c\/li\u003e\n    \u003cli\u003eTHD+N: 0.0015% (1 kHz, 30 dB gain, +4 dBu output)\u003c\/li\u003e\n    \u003cli\u003eBandwidth (85 dB gain): –3 dB at 9 Hz \/ \u0026gt;200 kHz\u003c\/li\u003e\n    \u003cli\u003eMax input level: +20 dBu (minimum gain)\u003c\/li\u003e\n    \u003cli\u003eMax output level: +27 dBu (600 Ω)\u003c\/li\u003e\n    \u003cli\u003eHPF: –3 dB @ 115 Hz or 230 Hz, 6 dB\/oct\u003c\/li\u003e\n    \u003cli\u003ePhantom power: +48 V (per channel, switchable)\u003c\/li\u003e\n    \u003cli\u003ePolarity reverse: yes (per channel)\u003c\/li\u003e\n    \u003cli\u003ePower: external switching PSU\u003c\/li\u003e\n    \u003cli\u003eMade in: USA (Pasadena, CA)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"AEA","offers":[{"title":"Default Title","offer_id":54014135075153,"sku":"52367","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AEATRP31.jpg?v=1781105186","url":"https:\/\/wrdtunes.com\/de-fr\/products\/aea-trp3","provider":"Wired Tunes","version":"1.0","type":"link"}
