BEHRINGER XENYX QX1204USB Analog Mixer

For the volunteer at the back of the room.

The band arrives early and the service starts within the hour. Whoever runs sound has that time to get every voice clear. The QX1204USB puts four XENYX mic preamps and built-in effects on one 2.9 kg desk.

Steady voices with one knob

Each mono channel has its own compressor. Turn COMP clockwise and loud peaks are squashed while quiet passages come up. A 3-band EQ with a 2.5 kHz mid and a low cut filter tidy each microphone. Switchable +48 V phantom power feeds condenser mics.

Monitors and effects from the same desk

On the QX1204USB, aux send 1 can be switched pre-fader to feed stage monitors. The FX send goes straight to the built-in multi-FX processor, designed by Klark Teknik. Its presets include reverbs, delays, chorus and flanger.

Record the service, add a wireless mic

USB sends the main mix to a computer. Audio from the computer joins the main mix with the 2-TR/USB TO MAIN button. A USB wireless input takes a receiver for up to 2 Behringer ULM microphones. Each channel uses one source at a time: wireless, XLR or ¼" input. No driver is required, though PC users are advised to install the ASIO driver.

Features

• XENYX mic preamps: 4 mic inputs on balanced XLR connectors with a discrete input circuit and a gain range of +10 dB to +60 dB
• Mic preamp noise: E.I.N. of -134 dB (-136 dB A-weighted) at 0 Ω source resistance, measured 20 Hz to 20 kHz
• Phantom power: the PHANTOM switch supplies +48 V to the XLR connectors of the mono channels for condenser microphones
• One-knob compressor: each mono channel has a COMP knob, and the adjacent LED lights when the effect is engaged
• 3-band EQ: shelving bands at 80 Hz and 12 kHz plus a 2.5 kHz peak mid on all mono channels, each with up to 15 dB boost or cut
• LOW CUT filter: a high-slope filter on the mono channels removes unwanted low-frequency signal components
• Line inputs: each mono input also has a balanced ¼" line input, used instead of the mic input, never both at once
• Wireless input: a USB receiver input takes signals from 2 independent Behringer ULM wireless mics
• Monitor send: on the QX1204USB, aux send 1 switches pre-fader with the PRE switch for setting up monitor mixes
• Klark Teknik multi-FX: the FX send feeds the built-in processor, with presets such as CHURCH, PLATE REVERB 1, ECHO, CHORUS, FLANGER and TALKBOX
• Effect editing: turn PROGRAM to scroll through the effects, then press PARAM 1/2 to edit parameter 1 and 2
• Channel SOLO: the QX1204USB SOLO switch routes a channel to the solo or PFL bus to monitor it without affecting the main output
• ALT 3-4 subgroup: the MUTE/ALT 3-4 switch diverts a channel from the main mix to the Alt 3-4 bus and its unbalanced ALT 3-4 outputs
• Stereo channels: two balanced ¼" line inputs per stereo channel, with a LEVEL switch for +4 dBu or -10 dBV
• USB audio: a Type B connector with stereo in/out, 16-bit converter and 48 kHz sample rate; the computer receives the main mix
• Main outputs: balanced XLR connectors carrying the MAIN MIX signal at a nominal level of +4 dBu
• 2-track connections: RCA 2-TRACK INPUT and a 2-TRACK OUTPUT carrying the main mix for a recording device
• Size and weight: 265 x 330 x 90 mm (W x D x H) and 2.9 kg
