3.2 Simli ulanishlar
Refer to the diagram below for proper wiring connections. Ensure all connections are secure and insulated to prevent short circuits.
- Quvvat (BATT +12V): Connect directly to the positive terminal of the battery using a fuse or circuit breaker within 18 inches of the battery.
- Yer (GND): Connect to a clean, solid metal point on the boat's chassis or a dedicated ground bus. Ensure the connection is free of paint or corrosion.
- Masofaviy (REM): Connect to the remote turn-on lead from your head unit or a switched 12V source.
- Kiritish (AMP1, AMP2): RCA kabellarini bosh qurilmangizning oldingi qismidan ulang.amp ga chiqadi amplifier's input jacks.
- Speaker Output (AMP1 Bridged, AMP2 Bridged): Connect your speakers to the appropriate terminals. Observe correct polarity (+ to + and - to -). For bridged operation, refer to the specific bridging instructions in your head unit's manual.

4.1 Daromadni sozlash
GAIN boshqaruvi mos keladi amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum. Increase the head unit volume to about 75% of maximum. Slowly increase the amplifier's gain until you hear slight distortion, then back off slightly. The GAIN MATCH indicator will assist in setting the optimal gain.
4.2 Krossover sozlamalari
The amplifier features variable crossovers for each channel pair (AMP1 va AMP2). Use these to direct specific frequency ranges to your speakers.
- OFF/HP/LP/BP Switch: Select the desired crossover mode.
- HI-PASS (HPF): Allows frequencies above the set point to pass. Useful for full-range speakers to prevent low-frequency distortion.
- LO-PASS (LPF): Allows frequencies below the set point to pass. Typically used for subwoofers.
- BAND-PASS (BP): Allows a specific range of frequencies to pass, defined by both HPF and LPF settings.
4.3 KICK EQ
The KICK EQ control provides a bass boost at 40Hz, adjustable from 0 to +12dB. Use this feature to enhance low-frequency response as desired, but avoid excessive boost which can lead to distortion or speaker damage.
