Product Overview
The AEA TRP500 preamp is built on the foundation of the company's renowned circuit and topology of their original TRP preamp. It boasts low noise, musical sonics, and ultra-high gain and impedance of 100,000 Ohms. The TRP500 is a master at capturing the warmth and rich sound of ribbon mics as well as other high-end microphones. With a maximum gain of 85 dB and a minimal path architecture, this preamp ensures minimal interference, providing a clear and direct connection between you and your audience. Additionally, its gentle 115 Hz or 230 Hz high pass filter further enhances the audio quality.
AEA Features:

- Max Input Signal Level: 21.5 dBu at minimum gain (before 1% THD)
- Mic Gain Control: 12-position switch provides from +7dB to +65dB of gain for the preamplifier circuit, as measured between the input and output when the OUTPUT control is set fully counterclockwise (0 dB)
- Mic Output Trim: Output potentiometer provides from 0 dB (unity gain) to +20 dB of gain
- High Pass Filter Frequencies: 3-position on-off-on switch provides switchable first order passive high pass filter (-6 dB per octave) with cutoff frequencies (-3 dB) at 115 Hz and 230 Hz
- XLR Connector Polarity: Pin-1 is ground, pin-2 is high, pin-3 is low
- LED Signal Level Indicators: The green LED snaps on at -20 dBu to indicate the presence of signal; the yellow LED snaps on at 0 dBu; the red LED snaps on at +20 dBu to warn of approaching signal overload, which is 8 dB prior to clipping
