Check the listing for details. BAE 1073MPF 2-channel Microphone Preamp. Condition: New. Listed at 2895.00 USD. Dual-channel 1073-style Preamp with Highpass Filter The classic Neve 1073 wrote the book on characterful mic preamplification, so in designing its 1073MPF dual-channel mic/line preamp, BAE aimed high. It's amazing how well they succeeded. Done up in classic RAF blue-gray livery, the handwired, transformer-coupled, pure Class A 1073MPF is quite versatile, with 71dB of gain that lets you capture subdued sources with your favorite ribbon mic. Cranking the main gain stage enhances your tracks with tasty vintage-style coloration. The 1073MPF includes a highpass filter that lets you roll off mud, rumble, and other low-frequency content that can mar an otherwise perfect take. Under the bonnet reside the finest components, such as Carnhill transformers — like those found in vintage 1073s.
