ເມື່ອຕິດຕັ້ງ, ປັບ ampການຕັ້ງຄ່າ lifier ສໍາລັບປະສິດທິພາບສຽງທີ່ດີທີ່ສຸດ.
5.1 ໄດ້ຮັບການຄວບຄຸມ
The variable input gain control (MIN MAX GAIN) matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum. Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear slight distortion, then back off slightly. This ensures maximum clean output.
5.2 ການຕັ້ງຄ່າ Crossover
The ST-4XP-SQ-III features variable electronic crossovers for both High-Pass Filter (HPF) and Low-Pass Filter (LPF).
- HPF (High-Pass Filter): Allows frequencies ຂ້າງເທິງ the set point to pass through. Use this for full-range speakers to prevent them from playing low bass, which can cause distortion and damage.
- LPF (ຕົວກອງຕໍ່າຜ່ານ): Allows frequencies ຂ້າງລຸ່ມນີ້ the set point to pass through. Use this for subwoofers to ensure they only reproduce bass frequencies.
- ເຕັມ: Bypasses the crossover, allowing all frequencies to pass.
Adjust the HPF and LPF settings according to your speaker types and desired sound. Typical settings for full-range speakers might be an HPF between 80Hz-120Hz. For subwoofers, an LPF between 80Hz-100Hz is common.
5.3 Bass Boost
The variable bass boost control allows you to enhance low-frequency output. Use this feature sparingly, as excessive bass boost can lead to distortion and potential speaker damage. Adjust to taste, ensuring the sound remains clear.
5.4 Auto-on with Speaker Level Inputs
When using speaker level inputs, the amplifier can automatically detect an audio signal and power on. Ensure the 'AUTO TURN ON' switch is set to 'ON' if you wish to utilize this feature. If using a remote turn-on wire, set this switch to 'OFF'.
