Headliner R4 Mark2

The Headliner R4 Mark2 is a four-channel analog rotary DJ mixer designed for tactile control and flexible mixing. It combines large rotary channel controls, 3-band isolator EQ on every channel, and a selectable high-pass/low-pass analog filter with dedicated Frequency and Resonance controls.

Each channel features gain control with a Peak LED, headphone cue selection, filter activation, and rotary volume control. Genuine ALPS potentiometers provide smooth operation, while the refined filter circuitry ensures clean engagement and consistent performance.

Channels 1–3 each have a dedicated stereo RCA line input and a second stereo RCA input switchable between phono and line. Channel 4 adds a switchable phono/line input and a microphone input routed through its full channel controls, including gain, isolator EQ, filter, and cue monitoring. A separate front-panel microphone input is also provided.

The headphone section offers Cue/Master blending, split monitoring, level control, and both 6.3 mm and 3.5 mm headphone outputs. Independent Master and Booth sections feature balanced XLR and unbalanced RCA connections, while a separate RCA Record output allows recording without affecting the main output level.

The mixer has a sturdy metal chassis, premium dark wood side panels with precision-etched branding, and modular internal construction. It is powered by an external split-rail power supply with a locking Mini XLR connection.
