5. Pengaturan

5.1 Instalasi Driver

The Midiplus Smartface II is a "Class Compliant" USB audio interface. This means it works driverless with most modern operating systems.

• Mac OS/X: No driver installation is required. The device will be recognized automatically.
• Windows (XP SP2, Vista, 7, 8): The device will function using generic USB audio drivers. For optimal performance and lower latency, an ASIO driver is available for download. Please visit the official Midiplus website for the latest ASIO driver for Windows XP/Vista/Win7/Win8.

After connecting the device, ensure it is selected as the input/output device in your operating system's sound settings and your Digital Audio Workstation (DAW) software.

5.2 Koneksi Perangkat Keras

1. Pastikan komputer Anda dihidupkan.
2. Connect one end of the provided USB cable to the USB port on the rear panel of the Smartface II.
3. Connect the other end of the USB cable to an available USB port on your computer. The Smartface II is USB powered, so no external power adapter is needed.
4. Connect your studio monitors or headphones to the appropriate outputs (Line Out L/R or Headphone) on the Smartface II.
5. Connect your microphones or instruments to the XLR/TRS combo inputs on the front panel.

6. Petunjuk Pengoperasian

6.1 Menghubungkan Mikrofon dan Instrumen

• Mikrofon: Connect dynamic or condenser microphones using XLR cables to the combo inputs. For condenser microphones, activate 48V phantom power using the corresponding switch on the rear panel.
• Instrumen (misalnya, Gitar, Bass): Connect instruments directly using a 1/4" TS cable to the combo inputs. These inputs are Hi-Z compatible.
• Perangkat Tingkat Lini: Connect synthesizers, drum machines, or other line-level devices using 1/4" TRS or TS cables to the combo inputs or the dedicated Line In (L/R) on the rear panel.

Sesuaikan Dapatkan 1 Dan Dapatkan 2 knobs on the front panel to set appropriate input levels. Monitor the Peak/Signal LEDs to ensure the signal is strong but not clipping (red Peak LED). A green Signal LED indicates a healthy signal.

6.2 Phantom Power (+48V)

Phantom power (+48V) is required for most condenser microphones. To activate it:

1. Connect your condenser microphone to the desired XLR combo input.
2. Locate the corresponding +48V-1 On/Off or +48V-2 On/Off saklar di panel belakang.
3. Flip the switch to the "On" position. The +48V LED on the front panel will illuminate.

Peringatan: Do not activate phantom power for dynamic microphones or ribbon microphones unless specifically designed to handle it, as this can damage some microphones.

6.3 Pemantauan Langsung

The Smartface II offers direct monitoring, allowing you to hear your input signal directly from the interface with zero latency, bypassing your computer's processing.

• To enable direct monitoring, flip the Monitor Hidup/Mati switch on the rear panel to "On".
• Gunakan Stereo/Mono switch to select how your inputs are monitored:
  • Stereo: Input 1 will be heard on the left channel, and Input 2 on the right channel.
  • Mono: Both Input 1 and Input 2 will be summed to mono and heard equally on both left and right channels. This is useful when recording a single mono source.
• Sesuaikan Volume knob on the front panel for your headphone monitoring level.

6.4 Software Setup (DAW)

In your Digital Audio Workstation (DAW) software (e.g., Ableton Live, Logic Pro, Cubase, Studio One), you will need to select the Smartface II as your audio input and output device.

1. Buka perangkat lunak DAW Anda.
2. Navigate to the Audio Settings, Preferences, or Options menu.
3. Select "Midiplus Smartface II" (or similar) as your audio device.
4. If using Windows, select the ASIO driver for the Smartface II if you have installed it, for optimal performance.
5. Configure your input and output channels within the DAW to correspond with the Smartface II's inputs and outputs.

The Smartface II supports full duplex operation, allowing simultaneous recording and playback.

7. Pemeliharaan

• Pembersihan: Use a soft, dry, lint-free cloth to clean the exterior of the device. Do not use abrasive cleaners, solvents, or waxes.
• Penyimpanan: Saat tidak digunakan dalam jangka waktu lama, simpan perangkat di tempat yang sejuk dan kering, jauh dari sinar matahari langsung dan suhu ekstrem.
• Perawatan Kabel: Handle USB and audio cables carefully. Avoid sharp bends or kinks that can damage internal wiring.

8. Penyelesaian masalah

• No Sound from Outputs:
  • Check all cable connections (USB, Line Out, Headphone).
  • Ensure the Smartface II is selected as the output device in your computer's sound settings and DAW.
  • Verify the headphone volume knob is turned up.
  • Check the volume levels within your operating system and DAW.
• Tidak ada sinyal masukan:
  • Ensure your microphone or instrument is properly connected to the combo input.
  • Periksa Memperoleh knob for the corresponding input and increase it if necessary.
  • Verifikasi Signal/Peak LED. If no green light, there's no signal.
  • For condenser microphones, ensure Daya hantu +48V diaktifkan.
  • Check input selection in your DAW.
  • Ensure the correct input is selected in your computer's sound settings.
• Distorted Sound (Clipping):
  • Jika Puncak LED is red, the input signal is too hot. Reduce the Memperoleh knob for that input.
  • Check the output levels in your DAW and computer to prevent digital clipping.
• High Latency (Delay):
  • If using Windows, ensure the dedicated ASIO driver is installed and selected in your DAW.
  • Sesuaikan ukuran buffer di pengaturan audio DAW Anda. Ukuran buffer yang lebih kecil mengurangi latensi tetapi membutuhkan lebih banyak daya CPU.
  • Utilize the direct monitoring feature to eliminate latency when recording.
• Perangkat Tidak Dikenali oleh Komputer:
  • Coba port USB lain di komputer Anda.
  • Coba kabel USB lainnya.
  • Hidupkan ulang komputer Anda.
  • For Windows, ensure the necessary drivers are installed (or re-install them).
