Description

Professional Audio Attenuator switch with 24 positions, recommended to replace a potentiometer with a quality stepped 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. The A4 switch can be assembled with resistors up to 3.6mm diameter for the ladder type switch. 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.
