Description

High-End Audio Rotary switch, up to 24 positions, Series- and ladder type attenuator

The A4 is a individual customizable audio rotary switch which offers a huge range of rotary switches in series or ladder type attenuator configuration.

The High-End Elma rotary switch is developed with a PCB based switch contact system that is specifically designed to meet audiophile requirements for super sonic performance. All switches feature Elma´s hallmark indexing feel for outstanding tactile feedback and feel with a possible torque from 1.5 to 15Ncm. Selectable end stop. You can choose between horizontal PCB or vertical switch design and a THT version without pre-soldered resistors or the SMT version with pre-soldered high-precision low-noise thin-film resistors with input impedance options 10k, 25k, 50k oder 100k Ohm. The series A4 attenuators are available up to 8 channels and the ladder type attenuators up to 4 channels. This rotary switch is also available as concentric version. We offer customized THT version with custom selected resistors - If you need any custom solution, please contact us.
