Twenty-four step volume control with 60dB attenuation range and 0.5dB level change per step.

These attenuators use series resistor networks consisting of 23 non-inductive, low noise, SMD metal film resistors. The layout of the PC Boards and the choice of SMD resistors have reduced the signal path to a minimum length (typical five times shorter than conventional stepped attenuator designs). This design method achieves very low series inductance and low stray capacitance giving bandwidth beyond even the most demanding requirements.

There has been special care taken to ensure the durability of CT2. All contacts and PCB traces are gold plated to prevent corrosion. The rotary switch itself is a gold plated, high precision switch manufactured in Switzerland. There are zero compromises made in the design and manufacture of these devices.
