Ажиллагаа ба тохируулга
JBL S.tage GT90041 amplifier features several controls for fine-tuning your audio system.
Зураг: дээд view JBL Stage GT90041 amplifier's control panel, detailing input, gain, and crossover settings.
Gain Control (Input Sensitivity)
The "GAIN" control matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum. Play a dynamic piece of music through your head unit at about 75% of its maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back it off slightly. This ensures maximum clean output from the ampнастан.
Crossover Controls (LPF, HPF, FULL)
The amplifier features independent crossover controls for channels 1/2 and 3/4.
- LPF (Бага нэвтрүүлэх шүүлтүүр): Allows only frequencies below the set point to pass through. Useful for subwoofers. Adjustable from 32Hz to 320Hz.
- HPF (Өндөр нэвтрүүлэх шүүлтүүр): Allows only frequencies above the set point to pass through. Useful for full-range speakers to prevent them from playing low bass. Adjustable from 32Hz to 320Hz.
- БҮРЭН: Бүх давтамжийг нэвтрүүлэх боломжийг олгож, кроссоверыг идэвхгүй болгоно.
Adjust the LPF and HPF settings according to your speaker types and desired sound. For example, if using full-range speakers, set the HPF to protect them from very low frequencies. If using a subwoofer, set the LPF to ensure it only reproduces bass.
Басс EQ
The "BASS EQ" control provides a bass boost at 45Hz, adjustable from 0dB to 12dB. Use this to enhance bass response if desired. Start with 0dB and increase gradually to avoid distortion.
Protection Indicators
The amplifier includes protection circuitry. If the amplifier enters protection mode (indicated by a specific LED, typically red), it will shut down to prevent damage. Common causes include:
- Short circuit in speaker wiring.
- Overheating due to insufficient ventilation or excessive load.
- Хэт ихtage эсвэл undervoltagцахилгаан хангамжид e.
