The Bricasti Design

Model 20 Preamplifier

Available in Platinum and classic black finish, the M20 Series dual mono preamplifier builds on the analog design of the M12 dual mono source controller to deliver a rich analog experience with fluid, fast and tonally balanced audio. The M20 Features fully differential and independently buffered signal paths for superior isolation and purity of sound. A proprietary, all discrete resister ladder attenuator, ceramic circuit boards and three dynamic Class A linear power transformers create the ultimate platform for your audio system.

Reference tone

The attenuator is a discreet ladder of digitally controlled resistors in 1dB steps utilizing Vishay foil resistors in key locations in the circuit; we find them to have a unique sound so we employed them to impart a tonal character to the M20, and PCB material is made from ceramic materials with excellent dialectic properties. The final output buffers are a proprietary discreet design and level control is accomplished using a R2R ladder technique allowing for perfect balance and tonal character at any level with recall, programmable input offset and remote control capabilities.

Heart of your system

There are three separately buffered analog outputs, two balanced one unbalanced. The output buffers are our own discreet design that is based on our other products like the M1, M12 and M21. All signal switching and hard output mutes are done using logic controlled relays. With 3 separately buffered outputs the M20 is ideal for bi amp applications with two balanced outs to drive two power amps or running two or three zones.

Uniquely Bricasti

The M20 is a fully differential dual mono preamp powered by three linear power supplies, one for each of the analog sections and a separate supply for the digital control circuit processor to ensure isolation from the analog PCB and power supplies. So in this way the M20 is a full Class A design. The M20 comes complete with Stillpoints isolator feet, is available in our Classic finish of anodized black and clear aluminum or in the platinum Series with chrome front and brass fittings.

Masterfully connected

The M20 includes 2 balanced XLR inputs/outputs and 1 unbalanced, RCA input/output. Pre-set channel naming conventions from the display can be uniquely customized through the menu as well as fine adjustment of level offset. The trigger-out mini-jack on the rear can be connected to the our power amps like the M28s or DACs like the M21 to send a 5V DC voltage trigger to power them in and out of standby from power off or standby on the M20.

Handcrafted in the USA

All of our products are crafted in the old world tradition, in a classic brick mill building in Massachusetts USA by a team of individuals dedicated to excellence.
