The Tri-State outputs provide the option to select between the Inactive, Balanced, and Unbalanced modes. The Disabled mode allows for the output to be switched off when not in use, ensuring optimal and precise management of connections. At the heart of the system is an attenuator based on CRQL technology, enabling precise adjustment to the desired output levels. CRQL stands for "Constant Resistive Quadrupoles with a Logarithmic distribution architecture”. This internal circuit has the advantage of being inherently logarithmic, thus avoiding approximations like the more commonly used linear R-2R system in this type of application. The CRQL attenuator module uses quadrupoles composed solely of high quality metal-film resistors with a tolerance of 0.1%. It allows volume adjustment between -127.5 dB and +6 dB in 0.5 dB steps. To guarantee maximum signal integrity, our CRQL module contains no semiconductor components in series with the signal. Additionally, volume changes occur within a maximum of 150 ns after an audio signal zero-crossing.
