    This DACT CT2 attenuator is an individual channel fine adjustment control with 0.5dB level change between each step. It is ideal for when fine control of levels is required or for channel matching either in stereo of for surround sound systems. It is equally suited for audiophile applications and for professional applications. The series resistor networks consist of 23 non-inductive, low noise, SMD metal film resistors. The layout of the PC board and the choice of SMD resistors have reduced the signal path to a minimum length (typical five times shorter than conventional stepped attenuator designs with leaded resistors). The PCB design combined with the special resistors also account for the very low series inductance and the very low stray capacitance. The result is a bandwidth beyond even the most demanding audiophiles requirements.

    There has been special care taken to ensure the durability of the CT2. Therefore, all contacts and PCB traces are gold plated to prevent any corrosion. As a result, the CT2 will maintain its specifications after long time of use even in hot and humid environments. The rotary switch itself is a gold plated high precision switch manufactured in Switzerland.
