An image showing the BOSS Audio Systems NX2500.4 Onyx 4-Channel Amplifier, highlighting its compact design and connection terminals for power, ground, remote, inputs, and outputs.
4.3 Power Connection (BATT+)
Connect a heavy-gauge wire directly from the positive (+) terminal of the vehicle's battery to the BATT+ terminal on the amplifier. An in-line fuse holder with a fuse of appropriate rating (not supplied) must be installed within 18 inches (45 cm) of the battery.
4.4 Жерге туташтыруу (GND)
Connect a heavy-gauge wire from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection by scraping away any paint or rust from the contact point.
4.5 Remote Turn-On (REM)
REM терминалынан кичирээк калибрлүү зымды туташтырыңыз amplifier to the remote turn-on output of your head unit. This wire signals the amplifier to turn on when the head unit is activated.
4.6 Аудио киргизүү туташуусу
- RCA киргизүүлөр: If your head unit has RCA pre-amp outputs, connect RCA cables from the head unit to the amplifier's RCA INPUT terminals.
- Динамик деңгээлиндеги киргизүүлөр: If your head unit lacks RCA outputs, use the speaker-level inputs. Connect the speaker wires from your head unit's speaker outputs to the amplifier's high-level input connector (if provided).
4.7 Динамиктин чыгышын туташтыруу
Динамиктерге туташтырыңыз amplifier's speaker output terminals. Observe correct polarity (+ to + and – to –). The NX2500.4 supports various configurations:
- 4-канал режими: Connect four speakers, one to each channel output.
- Көпүрө режими: Connect two speakers (e.g., subwoofers) by bridging two channels together. Refer to the amplifier's terminal markings for correct bridging connections.
- Trimode Operation: Allows for a combination of stereo speakers and a subwoofer. Consult a wiring diagram for specific trimode connections.
5. Операция
орнотулгандан кийин, тууралоо ampоптималдуу үн аткаруу үчүн көтөргүч орнотуулары.
5.1 Башкаруу
The variable gain control (often labeled 'Input Level' or 'Gain') matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum, then slowly increase it until you achieve a clear, undistorted sound at your desired volume level from the head unit.
5.2 Кроссовер орнотуулары
The NX2500.4 features variable high-pass (HPF) and low-pass (LPF) crossovers:
- Жогорку өтүүчү чыпка (HPF): Allows frequencies above the set point to pass through, blocking lower frequencies. Use for full-range speakers to prevent distortion from bass frequencies.
- Төмөн өткөрүүчү чыпка (LPF): Allows frequencies below the set point to pass through, blocking higher frequencies. Use for subwoofers to ensure they only reproduce bass.
Adjust these settings based on the frequency response of your speakers and subwoofers to achieve a balanced sound.
5.3 Bass Boost
The variable bass boost control (0 to +18dB) allows you to enhance the low-end frequencies. Use this feature sparingly to avoid distortion and potential speaker damage. Adjust to your preference for added bass impact.
5.4 Remote Subwoofer Level Control
If a subwoofer is connected to the amplifier, the included remote level control allows for convenient, on-the-fly adjustments of the subwoofer's output level from the driver's seat.
5.5 Иштөө режимдери
The amplifier can be configured for different operating modes:
- 4 каналдуу стерео: For driving four full-range speakers.
- 2-Channel Bridged: For driving two subwoofers or high-power speakers.
- Tri-mode: A combination of 2-channel stereo and 1-channel bridged for a subwoofer.
Ensure the correct mode is selected via any switches on the amplifier and that wiring corresponds to the chosen mode.
