4. Setup

4.1 Power Connection

1. Ensure the mixer is placed on a stable, flat surface.
2. Connect the supplied power adapter to the 'AC POWER IN' port on the rear of the mixer.
3. Plug the power adapter into a suitable electrical outlet. Note that the mixer does not have a dedicated power switch; it powers on when connected to the mains. Consider using a power strip with an on/off switch for convenient power control.

4.2 Audio Input Connections

Connect your microphones, instruments, and other audio sources to the appropriate input jacks.

Figure 4.1: Example of a microphone setup for audio input.

• Microphones: Use XLR cables to connect microphones to the MIC inputs (Channels 1 and 2). If using condenser microphones, ensure +48V phantom power is enabled (see Section 5.5).
• Line-Level Instruments/Devices: Connect instruments (e.g., keyboards, guitars with preamps) or other line-level devices using 1/4" TS or TRS cables to the LINE IN jacks.

4.3 Output Connections

Connect the mixer's outputs to your monitoring system, amplifier, or recording device.

• Main Output: Use 1/4" TRS cables to connect the MAIN OUT (L/R) to your power amplifier, powered speakers, or recording interface.
• Control Room Output: Connect your studio monitors to the CTRL ROOM OUT (L/R) using 1/4" TS cables.
• Headphones: Plug your headphones into the PHONES 1/4" TRS jack.
• 2-Track Input/Output: Use RCA cables for connecting external recording devices or playback sources to the 2-TRACK IN/OUT.

4.4 USB Connection to Computer

The Q1002USB features a built-in USB audio interface for direct recording and playback with your computer.

Figure 4.2: Using the mixer with a computer via USB.

1. Connect a USB cable from the USB INTERFACE port on the rear of the mixer to an available USB port on your computer.
2. Your computer should automatically detect the mixer as an audio device. No special drivers are typically required for Windows or macOS.
3. Select the Behringer Q1002USB as your input/output device in your computer's sound settings and your Digital Audio Workstation (DAW) software.

5. Operating Instructions

5.1 Gain Staging

Proper gain staging is crucial for achieving optimal sound quality and avoiding distortion.

1. Start with all channel GAIN knobs at their minimum (fully counter-clockwise) position.
2. Set the main MIX fader to 0 dB.
3. While the audio source is active (e.g., speaking into a microphone, playing an instrument), slowly increase the GAIN knob for the respective channel.
4. Observe the CLIP LED for that channel. Adjust the GAIN so that the CLIP LED only flashes occasionally on the loudest peaks. This indicates a healthy signal level without clipping.

5.2 Using the Compressors

The Q1002USB features easy-to-use 'one-knob' compressors on the first two channels to smooth out dynamic range.

Figure 5.1: Visual representation of signal compression.

• Turn the COMP knob clockwise to increase the amount of compression.
• The COMP LED will illuminate to indicate that compression is active.
• Adjust the knob to achieve a more consistent and controlled sound, especially for vocals and instruments with wide dynamic swings.

5.3 Adjusting the 3-Band EQ

Each mono channel features a 3-band 'British' EQ for tonal shaping.

Figure 5.2: The 'British' EQ provides warm and musical sound characteristics.

• HIGH: Adjusts the treble frequencies (12 kHz).
• MID: Adjusts the mid-range frequencies (2.5 kHz).
• LOW: Adjusts the bass frequencies (80 Hz).
• The center position (12 o'clock) is flat (no boost or cut). Turn clockwise to boost, counter-clockwise to cut.

5.4 FX Send and Return

The FX send allows you to route signal to an external effects processor.

• Use the FX knob on each channel to send a portion of that channel's signal to the FX SEND output.
• Connect the FX SEND output to the input of your external effects processor.
• Connect the output of your effects processor back to one of the stereo line inputs (e.g., Channels 5/6 or 7/8) on the mixer.
• Adjust the level of the returned effect using the corresponding channel's LEVEL knob.

5.5 Phantom Power (+48V)

Phantom power is required for condenser microphones.

• Ensure all microphones are connected before activating phantom power.
• Press the PHANTOM +48V button to supply power to the XLR inputs. The corresponding LED will illuminate.
• Always turn off phantom power before connecting or disconnecting microphones to prevent potential damage.

5.6 USB/2-Track Routing

The USB/2-TRACK section controls how audio is routed to and from your computer.

• TO MAIN MIX: Press this button to send the USB/2-Track input signal to the main mix. This is useful for playing back audio from your computer through the mixer.
• TO PHONES/CTRL RM: Press this button to send the USB/2-Track input signal to the headphones and control room outputs, allowing you to monitor computer audio without sending it to the main mix.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Behringer XENYX Q1002USB mixer.

• Cleaning: Disconnect the mixer from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Avoid using abrasive cleaners, solvents, or waxes.
• Dust Protection: When not in use, cover the mixer with a dust cover to prevent dust and debris from entering the controls and internal components.
• Storage: Store the mixer in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
• Cable Management: Ensure all cables are neatly organized and not under strain to prevent damage to the connectors and ports.
