Elma A47 Audio Attenuator
Description
The High-End Audio rotary switch A47 by Elma has a special PCB contact-system for audio purpose. The A47 attenuator has 47 steps and can set up to 6 channels. The torque is 1,5Ncm 1-2 wafers, 3-4 wafers 2.5Ncm and 5-6 wafers 4Ncm and can be assembled with lownoise high-precise SMT thin-film resistors (10k, 25k, 50k, 100k or 600 R) or as THT-Version without preassembled resistors and eyelets for DIY assembling. For assembling you can take resistors with a diameter up to 2.8mm.
Elma A47 rotary switches have a high precise, tactile with a first class surface feel
