3. Setup
3.1 Unpacking and Initial Inspection
Carefully unpack the mixer and all accessories. Inspect the unit for any signs of damage during transit. Retain the packaging materials for future transport or storage.
3.2 Power Connection
Connect the supplied power cable to the mixer's power input and then to a suitable AC power outlet. The "Planet Earth" switching power supply is designed for global use (100-240 V), ensuring flexibility and energy efficiency.
3.3 Connecting Microphones and Instruments
The X1222USB features 6 mono mic inputs (XLR) with phantom power and 4 stereo line inputs. Channels 5/6 and 7/8 also include additional mic inputs. Use XLR cables for microphones and 1/4" TRS or TS cables for line-level instruments and devices.
- Microphones: Connect microphones to the XLR inputs (MIC) on channels 1-8. Activate phantom power (+48V) if using condenser microphones.
- Line-Level Devices: Connect keyboards, drum machines, or other line-level devices to the 1/4" LINE IN jacks. Stereo channels (5/6, 7/8, 9/10, 11/12) accept stereo signals via two 1/4" jacks (Left/Mono and Right).
- Channel Inserts: Channels 1-4 feature 1/4" TRS insert jacks for connecting external processors like gates or compressors.

3.4 Connecting Main Outputs and Monitoring
- Main Mix Outputs: Connect the balanced main mix outputs (XLR) to your power amplifier, powered speakers, or recording device.
- Control Room/Headphone Output: Use the 1/4" CONTROL ROOM OUT jacks to connect to studio monitors. Plug headphones into the 1/4" PHONES jack for personal monitoring.
- Rec Outputs: The stereo REC OUT (RCA) allows connection to a recording device.
4. Operating Instructions
4.1 Channel Controls
- GAIN: Adjusts the input sensitivity for each channel. Set this to achieve a healthy signal level without clipping.
- COMP (Channels 1-4): The "one-knob" compressor allows easy dynamic range control for vocals and instruments. Turn the knob clockwise to increase compression.
- EQ (HIGH, MID, LOW): The 3-band "British" EQ allows you to shape the tone of each channel. Adjust these knobs to boost or cut frequencies.
- AUX: Controls the amount of signal sent to the auxiliary sends. AUX 1 is pre-fader (for monitoring), and AUX 2 is post-fader (for effects or external sends).
- PAN/BAL: PAN (mono channels) positions the signal in the stereo field. BAL (stereo channels) adjusts the balance between left and right signals.
- MUTE: Mutes the channel's output to the main mix, subgroups, and aux sends.
- LEVEL FADER: Controls the overall volume of the channel in the main mix.

4.2 Main Section Controls
- Graphic EQ: The 7-band stereo graphic EQ can be assigned to the main mix or monitor mix for precise frequency correction.
- FBQ Feedback Detection System: Activates the FBQ system, which illuminates the faders of critical frequencies to help eliminate feedback.
- FX Processor: Select and adjust 16 editable, studio-grade effects. Use the PROGRAM knob to select effects and PARAMETER to adjust their settings. The TAP button allows for tempo-syncing time-based effects.
- XPQ 3D Stereo Surround: Engages the XPQ 3D effect for an enhanced stereo image.
- Voice Canceller: Reduces the vocal presence in pre-recorded tracks for karaoke applications.
- Main Mix Fader: Controls the overall output volume of the main stereo mix.

5.2 Recording Software
The mixer is compatible with various digital audio workstation (DAW) software. Behringer often provides free audio recording, editing, and podcasting software bundles (e.g., Audacity, Podifier, Juice, Podnova, Golden Ear) and instrument/effect plug-ins, which can be downloaded from their official website. This allows you to turn your computer into a complete home recording studio.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the mixer's surface. Avoid abrasive cleaners or solvents.
- Dust Protection: Keep the mixer covered when not in use to prevent dust accumulation, which can affect faders and rotary controls.
- Environmental Conditions: Operate the mixer in a dry environment, away from extreme temperatures, direct sunlight, and excessive humidity.
- Ventilation: Ensure proper ventilation around the unit to prevent overheating.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Power off; cables disconnected; faders down; mute engaged. | Check power, all cable connections, raise main and channel faders, disengage mute buttons. |
| Distorted sound | Input gain too high; output level too high; faulty cable. | Reduce input GAIN; lower main mix fader; check/replace cables. |
| Feedback (howling sound) | Microphone too close to speakers; critical frequencies boosted. | Reposition microphone; activate FBQ Feedback Detection System; use graphic EQ to cut problematic frequencies. |
| No phantom power for condenser mic | Phantom power not engaged. | Ensure +48V phantom power is switched on for the relevant channels. |
| USB audio not recognized | Incorrect USB cable; driver issue; computer settings. | Use a high-quality USB cable; install/update drivers from Behringer website; check computer's audio input/output settings. |
