2. Istruzzjonijiet ta' Setup

1. Ħoll il-Mikrofonu: Carefully remove the ACM1HB microphone and its cable from the packaging.
2. Locate the Calibration Port: Identify the dedicated microphone input port on your compatible amplifier or AV receiver. This port is typically a 3.5mm jack and may be labeled 'MIC', 'SETUP MIC', or 'AUDYSSEY MIC'.
3. Qabbad il-Mikrofonu: Insert the 3.5mm jack of the ACM1HB microphone cable firmly into the amplifier's calibration port.
4. Poġġi l-Mikrofonu: Place the microphone at your primary listening position. For optimal results, the microphone should be at ear level when seated, and positioned vertically. It is recommended to use a tripod or stand to maintain stability and height.

3. Istruzzjonijiet Operattivi

Once the microphone is connected and positioned, you can initiate the automatic room correction process on your amplifier. The exact steps may vary depending on your amplifier model and its specific calibration software (e.g., Audyssey MultEQ, MCACC, YPAO). Refer to your amplifier's user manual for detailed instructions on how to start and complete the calibration sequence.

1. Aċċess Amplifier Menu: Ixgħel tiegħek amplifier and navigate to the setup menu, usually accessible via your amplifier's remote control and on-screen display.
2. Select Room Correction: Find the 'Speaker Setup', 'Room EQ', or 'Auto Calibration' option within the menu.
3. Segwi l-Prompts fuq l-Iskrin: Il- amplifier will guide you through the calibration process, which typically involves playing test tones through each speaker and taking measurements at various listening positions. The ACM1HB microphone will capture these sounds for analysis.
4. Ħlief Settings: After the calibration is complete, the amplifier will prompt you to save the optimized settings. Confirm to apply the new audio configuration.

4. Manutenzjoni

To ensure the longevity and accuracy of your ACM1HB microphone, follow these simple maintenance guidelines:

• Tindif: Wipe the microphone's plastic body with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials, as these can damage the microphone element or casing.
• Ħażna: Store the microphone in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case to prevent dust accumulation and physical damage.
• Immaniġġjar: Handle the microphone carefully. Avoid dropping it or subjecting it to strong impacts, which can affect its internal components and calibration accuracy.
• Kura tal-Cable: Do not sharply bend or crimp the cable. Coil it loosely when storing to prevent damage to the internal wiring.
