Headliner R4 Mark2 - 4 Channel Rotary DJ Mixer

The Headliner R4 Mark2 is a four-channel analog rotary DJ mixer designed for DJs who appreciate warm analog sound, tactile control, and an intuitive mixing experience. Combining smooth rotary channel controls with a 3-band isolator EQ on every channel, a selectable high-pass and low-pass analog filter, and flexible monitoring options, the R4 Mark2 delivers expressive sound shaping and expanded connectivity in a refined format.

Each channel features genuine ALPS potentiometers, dedicated gain control with peak indication, headphone cue selection, filter activation, and independent rotary volume control. The redesigned analog filter circuitry provides clean engagement and smooth performance, with dedicated Frequency and Resonance controls for precise tonal shaping. The comprehensive headphone section includes Cue/Master blending, split monitoring, level control, and both 1/4-inch and 1/8-inch headphone connections.

The R4 Mark2 offers expanded input flexibility with switchable phono/line RCA inputs on all four channels, dedicated stereo line inputs on channels 1–3, and support for up to seven connected stereo line-level sources. Channel 4 also features a dedicated microphone input routed through its full channel control section, providing access to gain, 3-band isolator EQ, cue monitoring, rotary level control, and analog filtering. An additional front-panel microphone input with independent level control provides further connectivity.

Independent Master and Booth sections feature balanced XLR and unbalanced RCA outputs, while a separate RCA Record output allows DJs to capture their performances without affecting the main output level. Finished with a sturdy metal chassis and premium dark wood side panels featuring pronounced grain and precision-etched Headliner branding, the R4 Mark2 combines classic rotary mixing aesthetics with versatile modern functionality.
