4.1 Kontrolli ta' Front Panel

Image: Front panel of the Warm Audio WA12 MKII, showing all controls and indicators.

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.
Buttuna 48V: Activates +48V phantom power for condenser microphones. An indicator LED illuminates when active.
Buttuna PAD: Applies a -20dB attenuation to the input signal, useful for very loud sources to prevent clipping.
Buttuna POL (Polarità): Inverts the polarity (phase) of the input signal. Useful for correcting phase issues when using multiple microphones.
Buttuna TONE: Engages a tone-shaping circuit that alters the input impedance from 600 ohms to 150 ohms, providing a different sonic character.
Pum GAIN: Controls the input gain for the microphone or instrument signal, ranging from 29dB to 65dB.
Pum tal-ĦRUĠ: Jaġġusta l-livell tal-output ġenerali tal-preampaktar ħaj.
VU Meter LEDs: A series of LEDs indicating the output level, ranging from -20dB to +18dB, with indicators for 0dB, +08dB, and +18dB (clipping).
Buttuna POWER: Turns the unit on or off. An indicator LED illuminates when the unit is powered on.

4.2 Konnessjonijiet tal-Panew ta' wara

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

Input tal-mikrofonu XLR: Connect your microphone via a standard XLR cable.
Output tal-Linja XLR: Connect this output to your audio interface, mixer, or other recording equipment.
Input tal-Enerġija IEC: Connect the provided IEC cable here to power the unit.

5. Setup

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

Konnessjoni tal-Enerġija: Connect the IEC power cable to the rear panel of the WA12 MKII and then to a grounded AC power outlet.
Konnessjoni tal-mikrofonu: Connect your microphone to the XLR Microphone Input on the rear panel using a high-quality XLR cable.
Instrument Connection (Optional): If using an instrument, connect it to the 1/4" Instrument DI Input on the front panel. Ensure the HI-Z button is engaged.
Konnessjoni tal-Output: Connect the XLR Line Output on the rear panel to an input on your audio interface, mixer, or other recording device.
Qawwa Mixgħul: Press the POWER button on the front panel. The power indicator LED will illuminate.
Settings Inizjali: Set the GAIN and OUTPUT knobs to their minimum positions before connecting any audio sources to avoid sudden loud signals.

6. Istruzzjonijiet Operattivi

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

Gwadan Staging: 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.
Phantom Power (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.
Kuxxinett: 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.
Ton: 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. Manutenzjoni

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

Tindif: Uża drapp artab u niexef biex tnaddaf il-barra tal-unità. Evita prodotti tat-tindif jew solventi li joborxu.
Ħażna: Meta ma tkunx qed tuża l-unità, aħżenha f'post frisk u niexef 'il bogħod mix-xemx diretta u minn temperaturi estremi.
Ventilazzjoni: Ensure the unit has adequate airflow around it during operation to prevent overheating.
Kura tal-Cable: Handle all cables with care. Avoid bending or crimping them excessively.
