PCB for the Balanced Input and Attenuator for the USB SuperCodec project in the December 2021 issue of PE.
Please note this PCB is supplied without components.
This compact balanced input attenuator is designed to fit into the same instrument case as the USB SuperCodec covered in the September to November 2021 issues of PE. It provides four attenuation settings of 0dB, −10dB, −20dB and −40dB and has performance to match the superlative SuperCodec. Together, they form a potent recording and/or measurement system.
The PCB for the USB SuperCodec is available here.
