Getting Started 1 Special Design Features Thank you for purchasing the Nº326S Preamplifier. The Nº326S features audio circuits, controls, architecture, and optional phono modules based on the critically acclaimed Nº32. In fact, some audio circuits, such as the proprietary discrete volume attenuators, are identical to those found in the Nº32. The Nº326S is similar to the Nº320S, but the main circuit board has been replaced with an ® Arlon board that responds more quickly to transient signals in

An advanced dual-mono design allows the Nº326S to achieve exceptional channel separation. Both audio channels use independent power supplies, communication circuits, and audio circuits. In fact, each channel’s audio circuits are located in a separate area of the chassis. This innovative approach isolates each channel, allowing the Nº326
