5.2 Simba rekubatanidza
- B+ (Positive Power): Connect the B+ terminal to the vehicle's positive battery terminal using a suitable gauge power cable. An inline fuse (not supplied) must be installed within 18 inches (45 cm) of the battery.
- GND (Pasi): Connect the GND terminal to a clean, solid chassis ground point on the vehicle. Ensure the connection is free of paint and corrosion for optimal conductivity.
- REM (Remote Turn-On): Connect the REM terminal to the remote turn-on output of your head unit. This signal turns the amplifier on and off with your audio system.
5.3 Zvisungo zveMutauriri
Connect your subwoofer to the speaker output terminals of the amplifier. Ensure correct polarity (+ to + and - to -) for optimal sound reproduction. The PA 1 is a monoblock amplifier designed for a single subwoofer.
5.4 Input Signal Connection
The PA 1 offers both high-level and low-level (RCA) input options:
- High-Level Input: Use the provided high-level cables to connect directly to your vehicle's speaker outputs. This is ideal for factory head units without RCA pre-outs. The amplifier features High-Level Input Resistance (EPS) and adjustable input voltage (1-15V or 15-40V) for optimal integration.
- Yakaderera-Level Input (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit to the ampLifier's RCA yekupinza jacks.
5.5 Remote Level Control
Connect the wired remote level control to the 'REMOTE' port on the amplifier. This allows for convenient adjustment of the subwoofer output level from your listening position.

6.2 Wana Kugadziridza
The GAIN control matches the amplifier's input sensitivity to the output level of your head unit. To set the gain, start with the control at its minimum position. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the GAIN control until you hear distortion, then back it off slightly until the sound is clear. This ensures maximum clean output from the amplifier.
6.3 Low-Pass Filter (LPF)
The LPF (Low-Pass Filter) allows only frequencies below the set point to pass through to the subwoofer. Adjust the LPF frequency (range: 30 Hz - 220 Hz) to blend the subwoofer's output seamlessly with your main speakers. The filter slope is adjustable between 12 dB/octave and 24 dB/octave for precise control over the frequency rolloff.
6.4 Subsonic Sefa
The SUBSONIC filter removes extremely low frequencies (range: 20 Hz - 50 Hz) that are typically inaudible and can cause your subwoofer to over-excurt, potentially leading to damage. Setting this filter helps protect your subwoofer and improves overall sound quality by focusing its output on audible bass frequencies.
6.5 Input Voltage Kugadzirisa
For high-level inputs, the amplifier features a switch to adjust the input voltage range (1-15V or 15-40V). Select the appropriate range based on the output voltage of your vehicle's head unit to ensure proper signal processing.
