Headliner R4 Rotary DJ Mixer

The Headliner R4 is a 4 channel analogue rotary DJ mixer that brings classic feel, modern flexibility and serious sound quality into one compact, club ready package. With its smooth ALPS rotary pots, powerful analogue filter and comprehensive I/O, it is built for DJs who want warmth, precision and hands on control whether you are blending deep house, techno or disco edits.

Each of the four stereo channels offers line, phono or mic connectivity, full 3 band isolator EQ and a dedicated filter switch, while the master section gives you an analogue high pass / low pass filter, flexible headphone monitoring and independent master, booth and record outputs. Housed in a sturdy metal chassis with stained wood side panels, the R4 looks and feels as good as it sounds.

Classic Rotary Feel with Modern Control

The R4 delivers the smooth, musical response that rotary fans love, thanks to genuine ALPS potentiometers on the channel level controls. Four stereo channels each feature gain with peak LED, 3 band isolator EQ, headphone cue selector, generous channel volume knob and a filter activation switch, giving you precise control over every element of your mix while encouraging expressive, long form blending.

Powerful Analogue Filter on the Master

At the heart of the mixer sits an analogue filter on the master channel. You can switch between high pass and low pass modes and sculpt your sound with dedicated frequency and resonance controls. From subtle sweeps to dramatic build ups and breakdowns, the filter lets you shape transitions and add movement to your sets without relying on external effects.

Flexible Connectivity for Vinyl, Digital and Microphones

The R4 is designed to integrate easily into a wide range of DJ setups. Three stereo channels offer selectable line and phono RCA inputs for turntables and media players, while the fourth channel can be switched between stereo line and mono microphone. An additional microphone input with its own level control is located on the front panel, making it simple to connect an MC or host.

Independent Master, Booth and Record Outputs

Independent master and booth outputs, each with their own volume controls and both balanced XLR and unbalanced RCA connectors, ensure the R4 can feed club systems, monitors and smaller rigs with ease. Dual LED level meters on the master output help you keep levels in check, while a dedicated record output on unbalanced RCA jacks lets you capture your sets without affecting the main mix.

Comprehensive Headphone Monitoring

The headphone cue section is designed for confident, accurate beatmatching. You get headphone volume control, a cue/master mix control and a split monitor switch, along with a high current headphone amplifier and both 1/4” and 1/8” jacks. Whether you prefer traditional cueing or split monitoring, the R4 makes it easy to hear exactly what you need.

Robust Build and Modular Design

Built into a sturdy metal enclosure with stained wood side panels, the R4 combines a classic aesthetic with a road ready construction. Its modular internal design and external split rail power supply, connected via a locking mini XLR, are engineered for superior audio performance and reliable operation in demanding environments.

• Four Channel Analogue Rotary Layout - Four stereo channels with smooth rotary level controls, gain with peak LED, 3 band isolator EQ and cue selectors give you detailed control over your mix while delivering the fluid, musical feel that rotary mixers are known for.
• Master Analogue Filter with HP/LP Modes - A dedicated analogue filter on the master channel offers selectable high pass and low pass modes with frequency and resonance controls, letting you craft dynamic sweeps, tension building cuts and warm tonal shifts directly from the mixer.
• Extensive I/O for Turntables, Players and Mics - With four line inputs, three phono inputs and two microphone inputs across the rear and front panels, the R4 accommodates a wide variety of sources, from vinyl decks and media players to microphones for vocals and announcements.
• Independent Master, Booth and Record Outputs - Separate master and booth outputs with both balanced XLR and unbalanced RCA connections, plus a dedicated record output, provide flexible routing to PA systems, booth monitors and recording devices while maintaining clear, controlled levels.
