3. Configuració i connexions

3.1 Desembalatge i inspecció

Desembaleu amb cura la batedora i inspeccioneu-la per detectar qualsevol signe de danys durant el transport. Conserveu l'embalatge original per a futurs transports o emmagatzematge.

3.2 Connexió d'alimentació

Connect the supplied power cable to the mixer's power inlet on the rear panel and then to a suitable AC power outlet. Ensure the power switch is in the OFF position before connecting.

3.3 Connexions d'entrada

The UB2442FX-PRO offers various input options:

• Entrades de micròfon (XLR): Connect microphones to the XLR inputs (1-10) for balanced microphone signals. Activate phantom power (+48V) via the dedicated switch if using condenser microphones.
• Line Inputs (1/4" TRS/TS): Connect line-level devices such as keyboards, drum machines, or preamplifiers to the 1/4" TRS/TS inputs (1-16). Channels 1-10 are mono, while 11/12, 13/14, 15/16 are stereo pairs.
• Insercions de canal: Use the 1/4" TRS insert jacks on mono channels (1-10) to connect external signal processors like compressors or gates.

3.4 Connexions de sortida

The mixer provides comprehensive output flexibility:

• Main Outputs (XLR): Connect these balanced XLR outputs to your main PA system or recording interface.
• Sub Outputs (1/4" TS): Use the four subgroup outputs to route specific channels to external devices or separate ampcanals lifiers.
• Aux Sends (1/4" TS): Connect these to monitor systems, external effects processors, or other auxiliary devices.
• Control Room Outputs (1/4" TS): Connect to studio monitors for critical listening.
• Sortida d'auriculars (TRS de 1/4"): Connect stereo headphones for personal monitoring.
• Direct Outputs (1/4" TS): Each mono channel (1-10) has a direct output for multi-track recording.

3.5 Muntatge en bastidor

The mixer can be installed into a standard 19-inch equipment rack using the included rack-mount brackets. Attach the brackets to the sides of the mixer with the provided screws.

4. Funcionament del mesclador

4.1 Channel Strip Controls

Each input channel features a set of controls to adjust the signal:

• GUANY: Adjusts the input sensitivity for microphones or line-level signals. Set this to achieve a strong signal without clipping.
• TALL BAIX: Activates a high-pass filter to remove unwanted low-frequency rumble.
• EQ (equalitzador): 3-band equalizer with HIGH, MID (semi-parametric), and LOW controls to shape the tone of the channel.
• AUX SENDS: Controls the amount of signal sent to the auxiliary outputs for monitors or external effects.
• PA: Positions the channel's signal within the stereo field (left to right).
• MUT: Silences the channel's output to the main mix and subgroups.
• SOLO: Isolates the channel's signal for monitoring through headphones or control room outputs without affecting the main mix.
• SUB 1-2 / 3-4: Routes the channel to the selected subgroup.
• PRINCIPAL: Routes the channel directly to the main stereo mix.
• CHANNEL FADER: Adjusts the overall volume level of the channel.

4.2 Controls de la secció principal

The main section provides overall control of the mixer's output and monitoring:

• FADERS DE MIXA PRINCIPAL: Controls the overall volume of the main stereo output.
• SUBGROUP FADERS: Controls the volume of the four subgroups.
• PROCESSADOR FX: Selects and adjusts the built-in digital effects. Use the program knob to scroll through 100 presets and the FX send controls to apply effects to channels.
• AUX RETURNS: Controls the level of signals returning from external effects processors or other devices connected to the aux return inputs.
• CONTROL ROOM/PHONES: Adjusts the volume for the control room outputs and headphone output.
• MESURA DE NIVELL: Provides visual indication of output levels for the main mix and subgroups.

4.3 Using the Multi-FX Processor

The integrated multi-FX processor offers 100 studio-grade presets. To use it:

1. Gireu el PROGRAMA knob to select an effect preset. The display will show the preset number.
2. Utilitza el ENVIAR FX controls on individual channels to send a portion of that channel's signal to the effects processor.
3. Ajusteu el FX A PRINCIPAL fader in the main section to control the overall level of the effect returning to the main mix.

5. Manteniment

5.1 Neteja

Clean the mixer's exterior with a soft, dry cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the finish or internal components. Keep faders and knobs free from dust and debris.

5.2 Emmagatzematge

When not in use for extended periods, store the mixer in a cool, dry environment, away from direct sunlight and extreme temperatures. If possible, use the original packaging or a protective case to prevent dust accumulation and physical damage.

Aquesta secció tracta problemes comuns que podeu trobar amb la vostra batedora.

• Sense sortida de so:
  • Check power connection and ensure the mixer is turned on.
  • Verifiqueu que tots els cables d'entrada i sortida estiguin connectats correctament.
  • Ensure channel faders, main mix faders, and subgroup faders are raised.
  • Check that MUTE buttons are not engaged on channels or main mix.
  • Confirm that the correct input source is selected on channels.
• So distorsionat:
  • Reduce GAIN levels on input channels to prevent clipping (indicated by PEAK LEDs).
  • Lower channel faders or main mix faders if output meters are consistently in the red.
  • Check for impedance mismatches between connected equipment.
• Brunzit o soroll:
  • Assegureu-vos que tots els equips estiguin correctament connectats a terra.
  • Use balanced cables (XLR or TRS) where possible.
  • Check for faulty cables or connections.
  • Mantingueu els cables d'àudio allunyats dels cables d'alimentació.
• Channel Not Responding:
  • Verify the input source is working correctly.
  • Check the channel's MUTE button and SOLO button status.
  • Ensure the channel fader is raised and GAIN is set appropriately.
  • If using phantom power, ensure it is activated for condenser microphones.
