The JBL CSR-3SV is a wall-mounted remote controller designed for advanced commercial audio systems, enabling volume control and multi-source selection directly from a wall panel. As part of JBL’s CSR Series, it is built specifically for use with digital zone mixers like JBL CSM-21 mixer and JBL CSM-32 mixer, making it ideal for professional multi-source installations. This controller allows users to select between 3 different audio sources while adjusting volume, giving far greater flexibility than standard volume-only controllers. It is commonly used in environments where multiple audio inputs (e.g., Bluetooth, TV, background music) need to be controlled locally. The CSR-3SV operates using analog DC control via Cat5 (RJ45) and supports cable runs up to 305 meters (1000 ft), ensuring flexible installation across large commercial spaces. Designed with simplicity and reliability in mind, it features a clean wall-panel interface and requires no programming or software, making it easy for both installers and end users. ⚠️ Note: This model is discontinued, but still widely used in existing systems.
