Headliner R4 Rotary Mixer

Description

The Headliner R4 is a professional 4-channel analog rotary DJ mixer designed for precision, warmth, and seamless control. Featuring four stereo channels with multiple input options, an analog filter section, and a high-quality build, the R4 delivers exceptional sound for DJs playing house, techno, funk, soul, and disco.

Each channel includes gain control with peak LED, a 3-band isolator EQ, a headphone cue selector, a channel volume knob, and a filter activation switch. The master channel provides an analog filter with selectable High Pass and Low Pass modes, offering frequency and resonance controls to shape the sound.

For monitoring and connectivity, the R4 features a dedicated headphone cue control section with volume and mix control, as well as independent master and booth outputs with balanced XLR and unbalanced RCA connections. A separate record output and an additional front-panel microphone input with level control ensure full flexibility.

Built for durability and superior performance, the R4 boasts genuine ALPS potentiometers, a sturdy metal enclosure with stained wood side panels, and modular internal construction. The external split rail power supply, connected via a locking Mini XLR, ensures stable operation.
