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 6 channels. Switch torques of 1.5, 2.5 and 5 Ncm are standard, populated with low-noise, high precision SMT resistors (standard input impedances are 10k, 25k, 50k or 100k or 600Ohms), or non-populated THT versions which can be populated by the customer.The A47 series feature Elma’s hallmark indexing feel for superior tactile feedback.Features47 positions, with selectable end-stopsLow profile; 36 by 36 mmsUp to 6 channelsAvailable with pre-populated thin-film SMT resistors or non-populated THT versions10k, 25k, 50k, 100k or 600 Ohms standard input impedanceExceptional sonic performance with precise switch feelLow-bounce contact system with 3 micron gold platingMotorized, IR controllable versions availableFree Excel resistor calculator tool available
