• 1/4" Instrument DI Input: Connect high-impedance instruments such as guitars or basses here.
• HI-Z Button: Engages the high-impedance input for instruments, optimizing the signal path.
• Tombol 48V: Activates +48V phantom power for condenser microphones. An indicator LED illuminates when active.
• Tombol PAD: Applies a -20dB attenuation to the input signal, useful for very loud sources to prevent clipping.
• POL (Polarity) Button: Inverts the polarity (phase) of the input signal. Useful for correcting phase issues when using multiple microphones.
• Tombol NADA: Engages a tone-shaping circuit that alters the input impedance from 600 ohms to 150 ohms, providing a different sonic character.
• MENDAPATKAN Knob: Controls the input gain for the microphone or instrument signal, ranging from 29dB to 65dB.
• Kenop KELUARAN: Menyesuaikan tingkat output keseluruhan dari praamppengangkat.
• VU Meter LEDs: A series of LEDs indicating the output level, ranging from -20dB to +18dB, with indicators for 0dB, +08dB, and +18dB (clipping).
• Tombol power: Turns the unit on or off. An indicator LED illuminates when the unit is powered on.

4.2 Sambungan Panel Belakang

The rear panel of the WA12 MKII provides the necessary connections for integrating the unit into your audio setup.

• Masukan Mikrofon XLR: Connect your microphone via a standard XLR cable.
• Keluaran Jalur XLR: Connect this output to your audio interface, mixer, or other recording equipment.
• Masukan Daya IEC: Connect the provided IEC cable here to power the unit.

5. Pengaturan

Follow these steps to set up your Warm Audio WA12 MKII:

1. Sambungan Daya: Connect the IEC power cable to the rear panel of the WA12 MKII and then to a grounded AC power outlet.
2. Koneksi Mikrofon: Connect your microphone to the XLR Microphone Input on the rear panel using a high-quality XLR cable.
3. Koneksi Instrumen (Opsional): If using an instrument, connect it to the 1/4" Instrument DI Input on the front panel. Ensure the HI-Z button is engaged.
4. Koneksi Keluaran: Connect the XLR Line Output on the rear panel to an input on your audio interface, mixer, or other recording device.
5. Nyalakan: Press the POWER button on the front panel. The power indicator LED will illuminate.
6. Pengaturan Awal: Set the GAIN and OUTPUT knobs to their minimum positions before connecting any audio sources to avoid sudden loud signals.

6. Petunjuk Pengoperasian

Operating the WA12 MKII involves adjusting its various controls to achieve the desired sound and level.

• Dapatkan Stagsedang: Begin by slowly increasing the GAIN knob until the desired input level is achieved. Monitor the VU Meter LEDs to ensure the signal is not clipping (red +18dB LED). Adjust the OUTPUT knob to control the signal level sent to your recording device.
• Daya Phantom (48V): If using a condenser microphone, press the 48V button to supply phantom power. Always connect the microphone before engaging phantom power and disengage it before disconnecting the microphone.
• Bantalan: For very loud sources (e.g., close-miked drums, loud guitar amps), engage the PAD button to reduce the input signal by 20dB, preventing distortion.
• Polarity (POL): Use the POL button to invert the phase of the input signal. This can be crucial when recording with multiple microphones to avoid phase cancellation issues.
• Nada: The TONE button changes the input impedance, offering a different sonic flavor. Experiment with this setting to find what best suits your microphone and source.
• HI-Z: When connecting an instrument directly to the 1/4" input, ensure the HI-Z button is engaged for proper impedance matching.

7. Pemeliharaan

Proper maintenance will ensure the longevity and optimal performance of your WA12 MKII.

• Pembersihan: Gunakan kain lembut dan kering untuk membersihkan bagian luar unit. Hindari pembersih atau pelarut abrasif.
• Penyimpanan: Saat tidak digunakan, simpan unit di tempat yang sejuk dan kering, jauh dari sinar matahari langsung dan suhu ekstrem.
• Ventilasi: Ensure the unit has adequate airflow around it during operation to prevent overheating.
• Perawatan Kabel: Handle all cables with care. Avoid bending or crimping them excessively.

8. Penyelesaian masalah

If you encounter any issues with your WA12 MKII, refer to the following common problems and solutions:

• Tidak Ada Daya:
  • Check if the IEC cable is securely connected to the unit and the power outlet.
  • Pastikan stopkontak berfungsi.
