The A47 audio switch series incorporates a PCB based switch contact system that is specifically designed to meet audiophile requirements for superb sonic performance.
These series attenuators provide 47 positions and are available from 1 to 8 channels. Switch torques of 4 and 8 Ncm are standard, populated with low-noise, high precision SMT resistors (standard input impedances are 10k, 25k, 50k or 100k), or non-populated THT versions which can be populated by the customer.
