The SNI-50A features adjustable output levels. These adjustments are typically small potentiometers (screws) on the unit itself, allowing you to match the output signal strength to the input sensitivity of your amplifier. Use a small screwdriver to carefully turn the adjustment screws. Start with the adjustments at their minimum setting and gradually increase them until the desired volume and clarity are achieved without distortion.

• Turn the head unit volume to about 75% of its maximum.
• Adjust the SNI-50A's output level until the amplifier's input gain is set correctly (refer to your amplifier's manual for gain setting instructions).
• Avoid setting the output level too high, as this can introduce distortion.

7. Tiaki

The PAC SNI-50A requires minimal maintenance to ensure long-term performance.

• Te horoi: Periodically wipe the unit with a soft, dry cloth to remove dust. Do not use liquid cleaners or solvents.
