Setup and Installation
Unpacking
- Carefully remove the amplifier from its packaging.
- Inspect the amplifier for any signs of damage that may have occurred during shipping. If damage is found, contact your dealer immediately.
- Ensure all accessories (if any) are present.
Wiring Connections
Proper wiring is crucial for the amplifier's performance and safety. Always use high-quality wiring and connectors.
- Power (BATT+): Connect a heavy-gauge wire (e.g., 8-gauge or larger, depending on total system power) directly from the positive terminal of the vehicle's battery to the amplifier's BATT+ terminal. Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Ground (GND): Connect a heavy-gauge wire of the same size as the power wire from the amplifier's GND terminal to a clean, unpainted metal surface of the vehicle's chassis. Ensure a solid electrical connection.
- Remote (REM): Connect a smaller gauge wire (e.g., 18-gauge) from the amplifier's REM terminal to the remote turn-on output of your head unit. This wire signals the amplifier to turn on and off with your audio system.
- Speaker Outputs: Connect your speakers to the amplifier's speaker output terminals. Observe correct polarity (+ to + and - to -) for each speaker. The TT2200 supports 2-channel stereo operation or bridged mono operation.
- RCA Inputs: Connect RCA cables from the pre-amp outputs of your head unit to the amplifier's RCA input jacks.
- Hi-Level Input: For head units without RCA outputs, use the provided Hi-Level Input connection. Connect the speaker outputs of your head unit directly to this input.
Operation
Initial Power-On
- After all connections are made and verified, reconnect the vehicle's battery negative terminal.
- Turn on your head unit. The amplifier's power indicator should illuminate.
- Start with the amplifier's input sensitivity (gain) control set to minimum.
- Gradually increase the head unit's volume to a moderate level, then slowly increase the amplifier's input sensitivity until the desired volume is achieved without distortion.
Adjusting Settings
- Variable Low-Pass Crossover (LPF): Adjust this control (50Hz - 150Hz) to filter out high frequencies from the signal, typically used for subwoofers or mid-bass speakers.
- Variable High-Pass Crossover (HPF): Adjust this control (50Hz - 500Hz) to filter out low frequencies, typically used for full-range or component speakers to prevent them from playing bass notes they cannot reproduce effectively.
- Variable Bass Boost: This control (0 - 18 dB) allows you to enhance bass frequencies at a specific frequency point. Use sparingly to avoid distortion.
- Phase Shift: Adjust this control (0 - 180°) to align the phase of the amplifier's output with other speakers in the system, improving bass response and overall sound clarity.
- Input Sensitivity: This control matches the amplifier's input level to the output level of your head unit (0.1V - 8V). Proper adjustment prevents distortion and maximizes dynamic range.
Maintenance
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's ventilation grilles are free from dust and obstructions to maintain proper cooling.
- Connections: Occasionally check all wiring connections to ensure they are secure and free from corrosion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Amplifier does not turn on | Blown fuse, poor power/ground connection, no remote signal. | Check in-line fuse, verify power and ground connections, ensure remote wire is connected and receiving 12V. |
| No Sound Output | RCA cables disconnected, speaker wires disconnected/shorted, amplifier in protect mode. | Check RCA and speaker connections, ensure speaker wires are not shorted, check for protect light (if illuminated, refer to manual or contact support). |
| Distorted Sound | Input sensitivity too high, speaker impedance mismatch, damaged speakers. | Reduce input sensitivity (gain), verify speaker impedance matches amplifier's capabilities, inspect speakers for damage. |
| Amplifier Overheating | Insufficient ventilation, low impedance load, prolonged high-volume use. | Ensure adequate airflow around the amplifier, verify speaker impedance, reduce volume or allow amplifier to cool. |
