Gwybodaeth Diogelwch
Arsylwch y rhagofalon diogelwch canlynol bob amser:
- Disconnect the vehicle's battery before any electrical installation to prevent short circuits.
- Ensure all wiring is correctly sized and fused according to specifications to prevent overheating and damage.
- Mount y amplifier securely in a well-ventilated area, away from moisture and direct heat.
- Osgoi gosod y amplifier in locations that obstruct vehicle operation or safety features.
- Ymgynghorwch â gosodwr proffesiynol os ydych chi'n ansicr ynghylch unrhyw ran o'r broses osod.
- Peidiwch â gweithredu'r amplifier with damaged cables or if it has been exposed to water.
Cynnyrch Drosview
The Stetsom IR 800.4 amplifier features a compact design with robust performance. It includes controls for level adjustment, high-pass filter (HPF), low-pass filter (LPF), and bass boost, allowing for precise audio tuning. It supports both RCA and high-level inputs for versatile integration with various head units.

Gosod a Gosod
Mae gosod priodol yn hanfodol ar gyfer perfformiad a diogelwch gorau posibl. Dilynwch y camau hyn yn ofalus:
1. Cysylltiadau Pwer
- Pŵer (BATT+): Connect a 6 AWG cable from the positive terminal of the vehicle's battery to the BATT+ terminal on the amplifier. Install a 40A fuse within 12 inches (30 cm) of the battery.
- Tir (GND): Connect a 6 AWG cable from the GND terminal on the amplifier to a clean, unpainted metal point on the vehicle's chassis. Ensure a solid electrical connection.
- O Bell (REM): Connect an 18 AWG cable from the remote output of your head unit (or an ignition-switched 12V source) to the REM terminal on the amplifier. This turns the amplifer ymlaen ac i ffwrdd gyda'ch uned ben.

2. Cysylltiadau Mewnbwn Sain
The IR 800.4 supports both RCA (low-level) and High Input (high-level) connections. Do not use both simultaneously, as this can cause unwanted noise and ampproblemau llewyr.
- Mewnbwn RCA: Connect RCA cables from your head unit's pre-out to the RCA input jacks on the amplifier (CH1/CH2 and CH3/CH4).
- Mewnbwn Uchel: If your head unit does not have RCA pre-outs, use the high-level inputs. Connect the speaker wires from your head unit directly to the High Input terminals on the ampllewywr.

3. Cysylltiadau Siaradwr
Cysylltwch eich siaradwyr i'r amplifier's speaker output terminals using 13 AWG cables. Ensure correct polarity (+ to + and - to -). The IR 800.4 supports both stereo and bridge modes. Always check the minimum impedance supported by the amplifier for your chosen configuration.
- Modd Stereo: Connect one speaker per channel. Minimum impedance is 2 Ohms per channel.
- Modd y Bont: Combine two channels to power a single speaker or subwoofer for increased power. Minimum impedance is 4 Ohms in bridge mode.

Cyfarwyddiadau Gweithredu
Ar ôl ei osod, addaswch y amplifier settings for optimal audio performance:
- Rheoli Lefel: Adjust the "LEVEL" knob for each channel pair (CH1/CH2 and CH3/CH4) to match the output voltage of your head unit. Start with the level at minimum and slowly increase it until the sound is clear and distortion-free at your desired maximum volume.
- Crossover Settings (HPF/LPF):
- HPF (Hidl Llwyddo): Fixed at 90 Hz. When active, it allows frequencies above 90 Hz to pass through, typically used for full-range speakers to prevent low bass distortion.
- LPF (Hidl Llwyddo Isel): Fixed at 90 Hz. When active, it allows frequencies below 90 Hz to pass through, typically used for subwoofers.
- Modd FLAT: When selected, both HPF and LPF are deactivated, allowing the amplifier to reproduce all frequencies supported by the amplifier without filtering.
- Hwb Bas: Use this control to enhance low-frequency output. Adjust carefully to avoid distortion.

Datrys problemau
Os ydych chi'n cael problemau gyda'ch amplifer, cyfeiriwch at y problemau a'r atebion cyffredin canlynol:
| Problem | Achos Posibl | Ateb |
|---|---|---|
| Dim Pŵer / Ampnid yw lififier yn troi ymlaen | Blown fuse, loose power/ground/remote wire, faulty head unit remote output. | Check fuse near battery. Verify all power, ground, and remote connections are secure and have proper voltage. |
| Dim Allbwn Sain | Loose RCA/High Input cables, incorrect input selection, speaker wires disconnected, amplifer mewn modd amddiffyn. | Check RCA/High Input connections. Ensure speaker wires are connected correctly and not shorted. Check if the "PROT" indicator is lit. |
| Sain ystumiedig | Gain (Level) set too high, incorrect crossover settings, speaker impedance mismatch, poor ground connection. | Reduce the "LEVEL" setting. Adjust HPF/LPF. Verify speaker impedance matches amplifier's capabilities. Improve ground connection. |
| Amplifier Gorboethi | Awyru annigonol, rhwystriant rhy isel, defnydd cyfaint uchel hirfaith. | Sicrhau amplifier has clear airflow. Check speaker impedance. Reduce volume or allow amplififier i oeri. |
