DESCRIPTION
The A47 audio switch series incorporates a PCB based switch contact system that is specifically designed to meet audio- phile requirements for superb sonic performance. These series attenuators provide 47 positions and are available from 1 to 6 channels. Switch torques of 1.5, 2.5 and 5 Ncm are available standard, populated with low-noise, high precision SMT resistors (standard input impedances are 600 ohm, 10 k, 25 k, 50 k or 100 k ohm) or non-populated THT versions (can be populated by the customer). The A47 series feature Elma’s hallmark indexing feel for superior tactile feedback. 11/65/EU)
