Setup

Proper setup is crucial for optimal performance of your XENYX QX1002USB mixer. Follow these steps to connect your equipment.

1. Power Connection

Connect the supplied power adapter to the "DC IN" jack on the rear panel of the mixer. Plug the other end of the power adapter into a suitable AC power outlet. The mixer does not have a power switch; it powers on automatically when connected to power.

2. Input Connections

The QX1002USB offers various input options:

• Microphone Inputs (Channels 1-2): Use XLR cables to connect microphones to the MIC inputs. These channels feature Behringer's XENYX Mic Preamps and can provide +48V phantom power for condenser microphones (activated via a switch on the top panel).
• Line Inputs (Channels 1-2): Use 1/4" TRS or TS cables for line-level sources such as keyboards, drum machines, or other audio devices.
• Stereo Line Inputs (Channels 3/4, 5/6, 7/8, 9/10): These stereo channels accept 1/4" TS cables for stereo line-level sources. Channels 9/10 also serve as the USB return channel.

3. Output Connections

Connect your monitoring and recording devices to the mixer's outputs:

• Main Outputs (MAIN OUT L/R): Connect these 1/4" TRS outputs to your main PA system, powered speakers, or power amplifier.
• Control Room Outputs (CTRL ROOM OUT L/R): Use these 1/4" TS outputs to connect to your studio monitors.
• Headphones Output (PHONES): Connect your headphones to the 1/4" TRS jack for personal monitoring.
• FX Send Output (FX SEND): This 1/4" TS output sends the signal to external effects processors.
• 2-Track Input/Output (2-TR IN/OUT): RCA connectors for connecting external recording devices or playback sources (e.g., CD player).

4. USB/Audio Interface Connection

Connect the mixer to your computer using a standard USB cable. The QX1002USB functions as a 2-in/2-out audio interface, allowing you to record the main mix to your computer and play back audio from your computer through the mixer (via channels 9/10).

Operating Instructions

This section details the functions of the various controls on your XENYX QX1002USB mixer.

1. Input Channels (Mono Channels 1-2)

• GAIN: Adjusts the input sensitivity for the microphone or line input. Set this to achieve a healthy signal level without clipping.
• COMP (Compressor): A one-knob compressor for dynamic range control. Turn clockwise to increase compression. Use this to smooth out vocal or instrument dynamics.
• EQ (Equalizer): Three-band "British" EQ for tone shaping.
• HIGH: Adjusts treble frequencies.
• MID: Adjusts mid-range frequencies.
• LOW: Adjusts bass frequencies.
• FX: Controls the amount of signal sent from this channel to the internal Klark Teknik effects processor.
• PAN: Positions the channel's signal in the stereo field (left to right).
• LEVEL: Adjusts the overall volume of the channel in the main mix.

2. Stereo Input Channels (Channels 3/4, 5/6, 7/8, 9/10)

• These channels typically have fewer controls, often including EQ, FX send, BALANCE (instead of PAN), and LEVEL. Channels 9/10 also serve as the USB return.

3. Klark Teknik Multi-FX Processor

• PROGRAM: Rotary encoder to select from 100 built-in effects presets (reverb, chorus, flanger, delay, pitch shifter, multi-effects). The display shows the selected program number.
• TAP: Button for setting the tempo of time-based effects (like delay) by tapping it rhythmically.
• FX TO MAIN: Controls the overall level of the effects signal sent to the main mix.

4. Main Section

• MAIN MIX FADER: Controls the overall output volume of the main stereo mix.
• PHONES/CTRL ROOM: Controls the volume for the headphones and control room outputs.
• LEVEL METER: LED meters display the output level of the main mix. Aim for levels around 0 dB to avoid clipping (red CLIP LED).
• PHANTOM POWER (+48V) Switch: Activates phantom power for condenser microphones connected to channels 1 and 2. Ensure microphones are connected before activating.
• USB/2-TR TO MAIN: Routes the USB return or 2-Track input signal to the main mix.
• USB/2-TR TO CTRL ROOM/PHONES: Routes the USB return or 2-Track input signal to the control room and headphones outputs.

Maintenance

To ensure the longevity and optimal performance of your Behringer XENYX QX1002USB mixer, follow these maintenance guidelines:

• Cleaning: Disconnect the mixer from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners, abrasive cleaners, or solvents, as these can damage the finish and internal components.
• Ventilation: Ensure that the ventilation openings are not blocked. Adequate airflow prevents overheating.
• Storage: When not in use for extended periods, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. Protect it from dust and moisture.
