From the seller

The Sonifex Redbox RB-MA1 is a genuine hidden gem in the professional broadcast and studio world. While "legendary" may be a strong term, it certainly applies to its exceptional reliability, durability, and ultra-low noise performance. The preamp is fully functional and in excellent technical condition, with only age-related signs of use. Huge gain reserves: With an adjustable gain range from 36 dB up to an impressive 75 dB, it has more than enough power to drive even extremely quiet, gain-hungry microphones such as the Shure SM7B, RØDE PodMic, or classic ribbon microphones effortlessly and without introducing unwanted self-noise. It also provides 48V phantom power for condenser microphones. High-quality internal components: At its core is the renowned SSM2019 preamplifier chip, known for its outstanding dynamic range, extremely low distortion (THD), and exceptionally transparent sound reproduction. Condition & Appearance: The sale is without the original box (original packaging). The unit will be packed extremely securely and shock-resistant for shipping. The front panel was professionally repainted because it had faded slightly from UV light, so it looks fresh again. Technically, everything works perfectly. Private sale. No warranty, guarantee, or returns. Original retail price: approximately €550.
