Based on the circuitry and topology of the company's original AEA TRP preamp, the TRP500 boasts the low noise, musical tones, and ultra-high gain and impedance (100 000 Ohms) which make the AEA famous. The TRP500 excels at bringing out the warmth and lush sound of ribbon mics as well as other high-end microphones. With up to 85 dB of quiet DC-coupled gain, minimal path architecture, and a smooth 115 Hz or 230 Hz high-pass filter, this preamp puts as little as possible between you and your audience.
Like all AEA products, the TRP500 is handcrafted in Pasadena, California using locally sourced parts. AEA is a family business with a small team of skilled technicians, many of whom are musicians themselves. Passive microphones, combined with the AEA line of ribbon-specific preamps, are the key choice for demanding recordists who want complete control over their signal path.
The ultra-high gain DC-coupled JFET circuit has two input impedances: 11,900 Ohms with phantom power “ON” and 100,000 Ohms with phantom power “OFF”. The 100,000 Ohm mode brings out the best in passive ribbon and tube mics, and also provides a unique balanced input for high-impedance vintage dynamic mics. This versatility ensures the highest possible sensitivity, bandwidth, transient response and clarity for a wide variety of microphones.
