Headliner HL90120 R4 4-Channel Analog Rotary DJ Mixer

Headliner R4 is a four channel analog rotary DJ mixer designed for professional and enthusiast DJ environments. It enables precise level control and tonal shaping for DJs who prefer rotary mixing workflows, supporting multi-source vinyl and line based setups. This makes it ideal for club, studio, and home DJ systems where control, flexibility, and sound character are critical.

The R4 features fully analog signal paths with selectable high pass and low pass filter modes, frequency and resonance controls, and three band isolator EQ on each channel. Multiple line, phono, and microphone inputs support turntables, media players, and microphones within a single mixer.

Built with a robust metal chassis and stained wood side panels, the R4 supports reliable performance and long term durability. Independent master and booth outputs, record outputs, and headphone monitoring provide flexible system integration across a wide range of DJ setups.
