The Avalon M5 is a 2U half-rack/desktop mounted Class A microphone preamp unit.
With a straightforward design layout, the Avalon M5 just lets you get on with the job - getting the best out of your microphone collection. If you want to hear smooth and shiny vocals, a clean and transparent sound that captures all the detail with a full dynamic range - then the Avalon M5 is where you need to go.
Built around the low-noise Class A circuitry that has made Avalon Design famous since its inception, the M5 preamp keeps signal paths short and uninterrupted - so less signal is lost in transit and all the best comes out. Fitted with a variable HPF, phase reverse, pad and phantom power, the M5 Preamp also functions as a top-quality DI box as well.
This high-quality mic preamp boasts some impressive technical figures with impressive + 30dB headroom and -126dB of noise, the Avalon M5 is extremely clean. 64dB of gain is provided in stepped 2dB increments, and should be enough to power Ribbon microphones.
From the start, Avalon Design set out to make professional products for professional situations - they wanted you to notice how good the best can sound. With the Avalon M5 Preamp to set your sound, it will get the best out of you, too.
