5.1 מאָנטירן די Ampליפער
Choose a mounting location that is dry, well-ventilated, and secure. Ensure sufficient space around the amplifier for air circulation. Use the provided mounting hardware to firmly secure the amplifier to a solid surface in the vehicle.

5.2 וויירינג קאַנעקשאַנז
Refer to the diagram below for connection points. Always use appropriate gauge wiring.
בילד 5.2: איבערview of amplifier connections and controls.
- מאַכט קאַנעקשאַן (+24V): Connect a fused 24V power cable directly from the vehicle's battery. Ensure the fuse is located close to the battery.
- ערד קאַנעקשאַן (GND): Connect a short, heavy-gauge cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle chassis.
- ווייטער-אינסטאלירן (REM): If using low-level inputs, connect this to the remote output of your head unit. If using high-level inputs with Auto-Turn-On, this connection may not be necessary.
- רעדנער אַוטפּוץ: Connect your speakers to the FRONT and REAR output terminals. Observe correct polarity (+/-). For bridged mode, refer to the specific bridging instructions.
- אַרייַנשרייַב קאַנעקשאַנז:
- הויך-מדרגה אַרייַנשרייַב: Connect the speaker outputs from your head unit directly to the amplifier's high-level input terminals. This is ideal for factory radios without RCA outputs.

5.3 Auto-Turn-On Function
The AT401 features an Auto-Turn-On function for high-level inputs. This allows the amplifier to turn on automatically when it detects an audio signal from the head unit, eliminating the need for a separate remote turn-on wire. Ensure the switch is set to the appropriate mode (DC or VOX) for this function.

6. אַפּערייטינג ינסטרוקטיאָנס
Once installed, the AT401 amplifier offers various adjustments to fine-tune your audio system.
6.1 Gain (SENS) Adjustment
The gain control (SENS) matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum. Gradually increase the head unit volume until distortion is heard, then back off slightly. Then, slowly increase the amplifier's gain until the desired volume is achieved without distortion.
6.2 Crossover (X-OVER) Settings
The AT401 features integrated 12 dB/octave electronic crossovers, adjustable from 40 to 400 Hz. These allow you to filter specific frequency ranges to your speakers.
Image 6.1: Adjustment options for crossovers and input sensitivity.
- HPF (הויך-פּאַס פילטער): Allows frequencies אויבן the set point to pass through. Use for full-range speakers to prevent low bass distortion.
- LPF (נידעריק-פּאַס פילטער): Allows frequencies אונטן the set point to pass through. Use for subwoofers.
- פול: Disables the crossover, allowing all frequencies to pass.
Adjust the FREQ knob to select the desired crossover frequency for each channel pair (FRONT/REAR).
