3. Opsætning
3.1 Udpakning og første inspektion
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 Strømtilslutning
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 Tilslutning af mikrofoner og instrumenter
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.
- Mikrofoner: Connect microphones to the XLR inputs (MIC) on channels 1-8. Activate phantom power (+48V) if using condenser microphones.
- Linjeniveau-enheder: 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 ampen højttaler, aktive højttalere eller en optageenhed.
- 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. Betjeningsvejledning
4.1 Kanalkontrol
- GEVINST: Justerer indgangsfølsomheden for hver kanal. Indstil denne for at opnå et sundt signalniveau uden afskæring.
- COMP (Kanal 1-4): The "one-knob" compressor allows easy dynamic range control for vocals and instruments. Turn the knob clockwise to increase compression.
- EQ (HØJ, MELLEM, LAV): 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.
- STUM: Mutes the channel's output to the main mix, subgroups, and aux sends.
- LEVEL FADER: Styrer den samlede lydstyrke for kanalen i hovedmixet.

4.2 Main Section Controls
- Grafisk 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.
- Stemmeannullerer: Reduces the vocal presence in pre-recorded tracks for karaoke applications.
- Main Mix Fader: Styrer den samlede udgangsvolumen for hovedstereomixet.

7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen lydudgang | Power off; cables disconnected; faders down; mute engaged. | Check power, all cable connections, raise main and channel faders, disengage mute buttons. |
| Forvrænget lyd | For høj indgangsforstærkning; for højt udgangsniveau; defekt kabel. | Reduce input GAIN; lower main mix fader; check/replace cables. |
| Feedback (hylende lyd) | 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-lyd genkendes ikke | 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. |
