5.1 ການເຊື່ອມຕໍ່ສາຍໄຟ
ປະຕິບັດຕາມຂັ້ນຕອນເຫຼົ່ານີ້ສຳລັບສາຍໄຟທີ່ເໝາະສົມ:
- Power (+BAT): Connect the +BAT terminal to the vehicle's positive battery terminal using a fuse (not included) close to the battery.
- ດິນ (GND): Connect the GND terminal to a clean, solid chassis ground point in the vehicle.
- ການປ້ອນຂໍ້ມູນທາງໄກ (REM IN): Connect the REM IN terminal to the remote output of your head unit or ignition switch. This signal turns the DSP on and off.
- Audio Inputs (A, B): Connect your head unit's RCA outputs to the DSP's Input A and Input B.
- Audio Outputs (1, 2, 3, 4): Connect the DSP's RCA outputs (1-4) to the inputs of your ampຜູ້ຊ່ວຍຊີວິດ.
- Remote Output Sequencer (AMP S1, S2, S3): These outputs provide sequential triggering for external amplifiers or other accessories. Connect these to the remote input terminals of your ampຜູ້ຊ່ວຍຊີວິດ.
5.2 Sequencer Feature
The DSP 2.4X includes a built-in sequencer feature that allows for sequential activation and deactivation of connected devices, such as amplifiers, via the remote trigger connection (REM). This helps prevent turn-on/turn-off thumps and protects your audio system components.
- The sequencer has three outputs (S1, S2, S3).
- These outputs are activated and deactivated sequentially based on the REM IN signal.
- The triggering interval between each output can be set from 0s to 4s.
- If the interval is set to 0s, all three outputs will activate/deactivate simultaneously after a 3-second delay from the REM IN signal change.
- Use cables of at least 20 AWG for remote signal connections.
