Citronic CSR-63 9-Channel Rack-Mount Mixer with Bluetooth & DSP Effects

Introducing the Citronic CSR-63, a robust and versatile rack-mountable 9-channel mixer designed to meet the demanding needs of live performers, audio engineers, and sound enthusiasts.

Whether you’re setting up an installed PA system or need a reliable mixer for mobile use, the CSR-63 is engineered to deliver exceptional audio quality and seamless control.

The CSR-63 boasts 6 mic/line channels and 3 stereo line channels. Each channel is equipped with individual gain, 2-band EQ, FX, and PAN control, alongside a smooth 60mm level fader for precise mixing.

Enhance your sound with the built-in DSP effects section, featuring 16 editable presets. For added convenience during live performances, the effects can be activated remotely via a foot switch.

Stream audio effortlessly from any Bluetooth-enabled device, integrating modern wireless technology into your setup. The 6 mono input channels feature individually switchable +48V Phantom Power, ideal for condenser microphones and other professional audio equipment.

When rack-mounted, the CSR-63 occupies slightly less than 4U of rack space, with top-mounted connectors for easy cable management. The end panels come with adjustable depth fixing, allowing you to position the controls either proudly for easy access or recessed for added protection. Unlike most rack mixers, the CSR-63’s shallow housing depth facilitates back-to-back mounting with other equipment, even in racks with rear mounting strips.

The Citronic CSR-63 is a problem-solver for both installed and mobile PA systems. Its comprehensive feature set and user-friendly design make it an excellent choice for a variety of audio applications, from live performances and studio recordings to event setups and broadcasting.

With its exceptional build quality, intuitive controls, and advanced features, the CSR-63 stands out as a reliable and versatile mixer. Whether you're a professional sound engineer or an enthusiastic performer, the Citronic CSR-63 will elevate your audio mixing experience, ensuring your sound is always top-notch.
