AEA TRP500 Preamp Module - Lunchbox 500 Series - B-Stock

AEA TRP500 Preamp Module - Lunchbox 500 Series - B-Stock

The AEA TRP500 is a 500 series preamp that delivers neutral, but rich and musical tonality with up to 85 dB of quiet DC-coupled gain.

This is a B-Stock Item. The unit comes with all original packaging and manufacturer warranty.

Based on the circuit and topology of the company’s original AEA TRP preamp, the TRP500 has the low noise, musical sonics, and ultra-high gain and impedance (100,000 Ohms) that AEA is renowned for. The TRP500 excels at drawing out the warmth and lush sound of ribbon mics as well as other top-level microphones. With up to 85 dB of quiet DC-coupled gain, minimal path architecture, and a gentle 115 Hz or 230 Hz high pass filter, this preamp puts as little as possible between you and your audience

Features:

• Single-channel, 500 series format
• 85dB of quiet, DC-coupled JFET gain
• Ultra-high impedance (100,000 Ohms)
• Switchable 115 Hz or 230 Hz high-pass filter
• Switchable phantom power and polarity reverse

Specifications

• Max Gain at 1kHz: 85 dB of gain, balanced-in to balanced-out
• EIN (Max gain): < –128 dBu (22 Hz to 22 KHz, unweighted, 40 Ohm source), typically -130 dBu
• DC Current Draw: from +16/-16V Rails: 130 mA
• Frequency Response:
• 30 dB gain: (+0/-0.6 dB from <10 Hz to 200kHz)
• 85 dB gain: (+0/-1 dB <20 Hz to >100kHz)
• (+0/-2.5 dB <10 Hz to 200kHz)
• THD+N: 0.0017% (1kHz, 22Hz-22kHz @30 dB Gain +4 dBu output)
• XLR Output Max Level: +28.5 dBu into 600Ω load (before 1% THD)
• Input Impedance: 11.9kΩ (with Phantom), 100kΩ (no Phantom)
• Output Impedance: 50Ω
• Max Input Signal Level: 21.5 dBu at minimum gain (before 1% THD)
• Mic Gain Control: 21.5 dBu at minimum gain (before 1% THD) 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
