This versatile preamplifier is designed with a focus on sonic purity, providing a rich and warm tone that is highly sought after in the audio industry.

The 12628-8 is built using hand-selected, high-mu 6922 vacuum tubes. These tubes provide a natural and detailed sound, with a low noise floor and a high degree of headroom.

The output transformer is also custom-wound by Manley Laboratories, providing a balanced and high-impedance output. This makes it compatible with a wide range of recording equipment, including console inputs, tape machines, and digital recorders.

Additionally, the 12628-8 includes a high-pass filter, which can be engaged to roll off unwanted low-frequency noise or rumble. This feature is particularly useful when recording acoustic instruments or vocals.

Overall, the Manley Laboratory 12628-8 is a top-of-the-line microphone preamplifier that delivers a rich and warm tone, low noise floor, and high degree of versatility. Its discrete Class A circuit design, custom-wound transformers, and hand-selected tubes make it a favorite among professional recording engineers and audio enthusiasts alike.
