Configurar

Instalação do driver

Before connecting the US-144MKII to your computer, it is crucial to install the latest drivers. The included CD may contain outdated drivers. For optimal performance and compatibility, always download the most current drivers directly from the official Tascam website. This ensures proper functionality and avoids potential issues, especially with newer operating systems.

1. Visit the official Tascam support website.
2. Locate the support page for the US-144MKII.
3. Download the appropriate driver for your operating system (Windows or macOS).
4. Follow the on-screen instructions to install the driver. Do not connect the US-144MKII until prompted by the installer, or until the installation is complete.

Conectando a Interface

1. Connect the US-144MKII to your computer using the supplied USB 2.0 cable. The unit is bus-powered, so no external power adapter is required.
2. Connect your microphones to the MIC/LINE Inputs (L/R) using XLR cables. If using condenser microphones, ensure the PHANTOM Power switch is engaged.
3. Connect line-level instruments (e.g., synthesizers) to the MIC/LINE Inputs (L/R) using 1/4-inch TRS cables, or a guitar/bass to the LINE/GUITAR IN (R).
4. Conecte seus monitores de estúdio ao SAÍDA DE LINHA (E/D) Conectores RCA.
5. Connect headphones to the 1/4-inch headphone jack on the front panel.
6. If using MIDI devices, connect them to the MIDI IN / OUT portas.

Operacional

Basic Recording Workflow

1. Ligar: Connect the US-144MKII to your computer via USB. The unit will power on automatically.
2. Configuração do software: Open your Digital Audio Workstation (DAW) software (e.g., Cubase LE4, included). Go to the audio settings/preferences and select the Tascam US-144MKII as your audio input and output device.
3. Ajuste de ganho de entrada: Connect your microphone or instrument. Speak into the microphone or play your instrument at the loudest expected level. Adjust the ENTRADA botão até que o SIG/OL indicator lights green consistently, only occasionally flashing red on peaks. Avoid constant red illumination, which indicates clipping.
4. Monitoramento:
   • For zero-latency monitoring, adjust the MON MIX knob. Turning it towards "INPUT" increases the direct signal from your microphone/instrument, while turning it towards "COMPUTER" increases the playback from your DAW. Find a balance that allows you to hear both clearly without delay.
   • Adjust your headphone volume using the TELEFONES knob and monitor speaker volume using the SAÍDA DE LINHA botão.
5. Gravação: Create a new audio track in your DAW, select the appropriate input (e.g., Input 1 for Mic L), and arm the track for recording. Press record in your DAW to begin.

Usando Phantom Power

If you are using a condenser microphone, it requires +48V phantom power. Ensure the microphone is connected before activating phantom power. Press the FANTASMA power switch on the front panel. The corresponding LED will illuminate. Always disengage phantom power before disconnecting condenser microphones.

Conectividade MIDI

The US-144MKII includes MIDI In and Out ports. Connect your MIDI keyboard, controller, or other MIDI devices to these ports. Your DAW software will recognize the US-144MKII as a MIDI interface, allowing you to send and receive MIDI data for controlling virtual instruments or external hardware.

Manutenção

• Limpeza: Use um pano macio e seco para limpar a parte externa da unidade. Não use produtos de limpeza abrasivos, ceras ou solventes.
• Armazenar: When not in use for extended periods, disconnect the USB cable and store the unit in a clean, dry place away from extreme temperatures.
• Cuidados com os cabos: Avoid bending or crimping USB and audio cables excessively. Store them neatly to prevent damage.

Solução de problemas

• No Sound/Device Not Recognized:
  • Ensure the latest drivers are installed from the Tascam website.
  • Verify the USB cable is securely connected to both the interface and the computer. Try a different USB port or cable.
  • Check your computer's sound settings and your DAW's audio preferences to ensure the US-144MKII is selected as the input/output device.
  • Restart your computer and the interface.
• Latency Issues (Delay in Monitoring):
  • Utilize o MON MIX knob for zero-latency hardware monitoring.
  • In your DAW, reduce the buffer size in the audio settings. Lower buffer sizes reduce latency but require more CPU power.
  • Ensure your computer meets the minimum system requirements for your DAW and the interface.
• Noisy Sound/Interference:
  • Verifique se todas as conexões dos cabos estão seguras e íntegras.
  • Ensure proper gain staging; avoid setting input levels too high, which can cause clipping and distortion.
  • Try using a different USB port, preferably one directly on your computer's motherboard rather than a hub.
  • Keep the interface away from other electronic devices that might cause interference.
• Interface Disconnects on Mac Sleep:
  • This can be a known behavior with some Mac systems. Try adjusting your Mac's energy saver settings to prevent USB ports from sleeping.
  • If the issue persists, you may need to unplug and re-plug the USB cable, and re-select the interface in your DAW's preferences after your Mac wakes up.
• Problemas de energia fantasma:
  • Ensure the microphone is properly connected before engaging phantom power.
  • Verify the microphone itself is functional and requires +48V phantom power.
