AEA RPQ503
UPC/EAN #652401978459
MPN #RPQ503
500 Series mic preamp with Ribbon Mic EQ, phantom power, and high-output gain. Cinemag input transformer, variable impedance, ultra-low noise design.
The AEA RPQ503 is a premium 500 Series mic preamp module specifically designed to bring out the full potential of ribbon microphones-especially AEA's own-but it works beautifully with condensers and dynamics as well. This high-gain, low-noise preamp is engineered with transparency and headroom in mind, preserving the integrity and detail of the original signal while adding subtle warmth.
At the heart of the RPQ503 is AEA's acclaimed CurveShaper EQ, which gives users fine control over tonal shaping without compromising the original character of the source. The HF boost enhances clarity and presence-ideal for vocals, acoustic instruments, or any track needing air-while the low-frequency filter helps manage proximity effect or tame excessive bass. With up to 81 dB of quiet gain, it's particularly suited for low-output ribbons and delicate sources, making it a studio essential for engineers who demand precision and musicality.
Features
Optimized for Ribbon Microphones: Provides high-gain, low-noise amplification ideal for passive ribbon mics.Powerful Dual Stage Gain: Clean 81dB of gain ensures full signal clarity even with quiet sources.Custom Input Impedance: High input impedance (63K ohms) preserves low-end and detail, especially for ribbons.Contour Circuit: Unique EQ circuit boosts presence or cuts muddy lows without altering character.Compact 500 Series Format: Fits into any standard 500 Series chassis like the AEA SNAQBOX.High-Headroom Performance: Handles transients and loud sources cleanly without distortion.Front Panel DI Input: Instantly connect instruments with dedicated high-impedance input.
