Essential features include a dedicated headphone output and a balanced direct output with switchable digital impulse-response cabinet emulation, making it a complete tool for various musical applications.

Características principales

• Six-band graphic equalizer with high and low shelf controls for detailed tone sculpting.
• XLR output with switchable cabinet simulation for direct connection to mixing consoles or audio interfaces.
• Headphone output with integrated IR cabinet simulation for silent practice and monitoring.
• Dedicated footswitch to independently engage or bypass the distortion engine.
• Master volume control to adjust the overall output level of the unit.

Configuración

Proper setup ensures optimal performance and sound quality from your Alpha Omega Ultra pedal. Follow these steps to connect your unit:

1. Conexión de energía: Connect a 9V DC power supply (center negative) to the 9 V CC input jack on the rear of the pedal. Ensure the power supply meets the pedal's requirements to prevent damage.
2. Entrada del instrumento: Conecte su bajo a la APORTE conector que utiliza un cable de instrumento estándar de 1/4 de pulgada.
3. AmpSalida del amplificador: Conectar el PRODUCCIÓN jack to your bass amplifier's input using a standard 1/4-inch instrument cable.
4. Entrada auxiliar: For practicing with backing tracks, connect an audio source (e.g., smartphone, MP3 player) to the AUX IN jack using a 1/8-inch stereo cable.
5. Salida de auriculares: Para practicar en silencio, conecta tus auriculares a la AURICULAR output jack using a 1/8-inch stereo cable.
6. Direct Output (XLR): For connecting to a mixing console, audio interface, or PA system, use an XLR cable from the SALIDA DIRECTA. This output includes switchable cabinet simulation.
7. Levantamiento de tierra: If you experience hum or ground loop noise when using the XLR output, press the ELEVADOR DE TIERRA button located near the USB port to isolate the ground connection.
8. Conexión USB: El USB port is used for connecting the pedal to a computer to load Impulse Responses (IRs) for cabinet simulation and for firmware updates.

Controles:

• mezclar: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the overdriven signal's volume is controlled by the Level knob, allowing for fine blending.
• Nivel: Sets the overall output volume of the overdriven signal.
• Conducir: Controls the amount of gain in the overdriven signal.
• Modificador: Selects between the Alpha (tighter, more defined) and Omega (rawer, more aggressive) distortion circuits. The knob blends between these two distinct voicings.
• Growl (Toggle Switch): Engages a bass boost before the distortion stage, adding thickness and low-end saturation.
• Bite (Toggle Switch): Engages a high-mid boost (2.8kHz) before the distortion stage, enhancing presence and attack.
• Maestro: Controls the overall volume of the pedal, affecting both clean and distorted signals, as well as the headphone and XLR outputs.

Ecualizador gráfico:

The Alpha Omega Ultra features a six-band graphic equalizer for precise tonal adjustments. Each slider controls a specific frequency band:

• Bajo: Low shelf control.
• 250 Hz: Mid-range frequency control.
• 500 Hz: Mid-range frequency control.
• 1.5 kHz: High-mid frequency control.
• 3 kHz: High-mid frequency control.
• Triplicar: High shelf control.

Interruptores de pie:

• Distortion Footswitch: Activates or bypasses the distortion engine. When engaged, the LED illuminates.
• Pedal de derivación: Activates or bypasses the entire pedal. When engaged, the LED illuminates.

Simulación de gabinete:

The Alpha Omega Ultra includes digital impulse-response (IR) cabinet simulation. This feature is active on the XLR Direct Output and the Headphone Output. You can load custom IRs via the USB port and Darkglass Suite software to tailor your cabinet sound.
