Behringer XENYX QX1204 USB Helimikser

Behringer XENYX QX1204USB — 12-Input Mixer with Built-In FX and USB Audio Interface

The Behringer XENYX QX1204USB combines a compact analog console with a stereo USB audio interface, giving small bands, podcasters, and project studios one hub for live sound and recording. Four phantom-powered XENYX mic preamps feed a 2/2-bus architecture with two aux sends, two subgroups, and balanced XLR main outputs. At 2.9 kg and 264 × 89 × 330 mm, this mixer travels easily between rehearsal rooms, stages, and desktops.

What Sets the QX1204USB Apart in Its Class

Rare at this price tier, the wireless-ready USB-A port accepts Behringer ULM-series digital microphone receivers for cable-free performances with up to two transmitters. The 24-bit KLARK TEKNIK Multi-FX engine ships with 100 storable presets, an LCD readout, dual-parameter control, and Tap-tempo. Long-wearing 60 mm logarithmic-taper faders are built for years of gigging.

Microphone Preamps and Input Routing — Capture Every Source Cleanly

Four XENYX mic preamps deliver a 130 dB dynamic range with a frequency response extending from below 10 Hz to above 200 kHz, capturing the full harmonic content of vocals and acoustic instruments. The mixer accepts up to 12 simultaneous inputs across 4 mono mic/line channels, 2 stereo line pairs, and an RCA 2-track input.

• Mic Preamps: 4 × XENYX — high-headroom design comparable to boutique standalone units
• Mic Gain Range: +10 to +60 dB — covers everything from quiet ribbon mics to loud stage dynamics
• Phantom Power — globally switchable +48 V supply for condenser microphones

British-Style EQ and One-Knob Compression — Shape Tone With Confidence

The neo-classic 3-band British EQ on every channel adds warmth derived from 1960s and 1970s console circuitry. One-knob compressors on mono channels 1–4 limit dynamic range, tame peaks, and add sustain without external processing knowledge.

• EQ Bands: Low ±15 dB at 80 Hz, Mid ±15 dB at 2.5 kHz, High ±15 dB at 12 kHz — broad tonal sculpting for vocals, drums, and guitars
• Compressor Channels — single-knob threshold control with LED indicator on mono inputs 1–4
• THD+N: 0.005% (0.004% A-weighted) — clean signal path from mic input to analog output

KLARK TEKNIK FX, USB Interface, and Output Flexibility — Live and Recording Ready

The built-in KLARK TEKNIK Multi-FX processor delivers studio-grade reverbs, choruses, flangers, delays, and pitch-shift effects without external hardware. A bi-directional USB-B port streams 2-in/2-out audio at 48 kHz / 16-bit to Windows or macOS, while a separate USB-A port accepts Behringer ULM wireless receivers.

• FX Engine: 24-bit KLARK TEKNIK, 100 presets — Tap tempo, dual-parameter editing, storable user settings
• USB Audio: 2 in / 2 out, 48 kHz / 16-bit — direct connection to a DAW with included recording software
• Aux Sends: 2 per channel (1 pre-fader, 1 post-fader) — separate monitor mix and FX loop routing
• Subgroups — two dedicated outputs for grouping drums, vocals, or instruments

Ideal Users — Solo Performers, Podcasters, Small Bands, and Project Studios

This mixer is the right choice for solo musicians, podcasters, and small ensembles who need a compact console that doubles as a recording interface. Solo performers benefit from the four high-headroom mic preamps and one-knob compressors that polish vocals without outboard gear. Podcasters gain a USB audio interface and 100 onboard effects for voice sweetening. Small bands route stage monitors via the pre-fader aux send while sending post-fader signal to the internal FX engine.

KLARK TEKNIK Heritage — 40 Years of Studio-Grade Effects

KLARK TEKNIK is a British audio company with a 40-year pedigree and a TEC Lifetime Achievement Award, whose DN780 reverb processor became an industry-standard reference. Behringer partnered with KLARK TEKNIK to custom-engineer the 24-bit Multi-FX engine used across the XENYX Q Series, bringing studio-grade processing to compact mixers.
