1. Power Connection:
- Connect a DC power supply (12-30V) to the "POWER DC 12-30V" input terminals. Ensure correct polarity (+ and -).
- Alternatively, use a 5.5-2.5mm DC jack if your power supply has one.
- Important: Ensure the power switch is in the "OFF" position before connecting power.
2. Speaker Connection:
- Connect your passive speakers to the "SPEAKERS" output terminals.
- Connect the left speaker to the "L+" and "L-" terminals.
- Connect the right speaker to the "R+" and "R-" terminals.
- Ensure proper polarity for optimal sound quality.
3. Audio Input Connection:
The amplifier supports three main audio input methods:
- Bluetooth: For wireless connection from smartphones, tablets, or computers.
- AUX: For wired connection via a 3.5mm audio jack from devices like TVs, computers, or MP3 players.
- USB: For playing audio files directly from a USB flash drive or using the board as a USB sound card for a computer.

4. Bluetooth Pairing:
- Ensure the amplifier is powered on and in Bluetooth mode (blue indicator light).
- On your device (smartphone, tablet), enable Bluetooth and search for available devices.
- Select "XY-T1002P" from the list to pair.
- Once paired, the blue indicator light may become solid or flash differently depending on the connection status.
5. AUX Input:
Connect your audio source to the 3.5mm AUX input jack. Switch the amplifier to AUX mode (red indicator light) using the multi-function knob.
6. USB Input:
Insert a USB flash drive containing audio files into the USB port. Switch the amplifier to USB mode (green indicator light). The amplifier will automatically detect and play compatible audio files (WAV, FLAC, APE, MP3). For USB sound card functionality, connect the amplifier to your computer via a USB cable and select it as the audio output device.
7. Treble and Bass Adjustment:
Use the dedicated "TREBLE" and "BASS" knobs to fine-tune the high and low frequencies of your audio output to your preference.
