Setup Instructions

Follow these steps to correctly assemble and connect your XY-E30H amplifier module.

1. Assembly (if required):

Place the circuit board onto the lower cover plate, aligning the screw holes.
Insert the M2x16 copper pillars into the designated holes on the circuit board and lower plate.
Secure the upper cover plate onto the copper pillars using the M2x3 screws.
Attach the knob caps to the three control shafts.
Use the provided screwdriver for assembly.

2. Power Connection:

Ensure the amplifier is turned off and all other connections are made before connecting power.
Connect a DC power supply (9-24V) to the DC-IN port on the module. Observe polarity: positive (+) to the center pin, negative (-) to the outer barrel.
Use a power adapter with sufficient current capacity for the amplifier's output (e.g., 12V 5A or 24V 3A for full power).

3. Speaker Connections:

Connect your speakers to the appropriate terminals as indicated on the module (refer to Figure 2).

Left Speaker: Connect to L+ and L- terminals.
Right Speaker: Connect to R+ and R- terminals.
Subwoofer: Connect to S+ and S- terminals.
Ensure correct polarity for all speaker connections to avoid phase issues.

4. Audio Input Connection:

AUX Input: Connect your audio source (e.g., smartphone, MP3 player) to the AUX IN port using a 3.5mm audio cable.
Bluetooth Input: The module will automatically enter Bluetooth pairing mode when powered on.

Operating Instructions

1. Powering On/Off:

Once all connections are secure, connect the power adapter to a wall outlet. The module will power on.
To power off, disconnect the power adapter from the wall outlet.

2. Volume Control:

The XY-E30H features three independent volume controls:

L&R VOL (Left & Right Channel Volume): Adjusts the volume of the main stereo speakers.
MASTER VOL (Master Volume): Controls the overall output volume of all channels (Left, Right, and Subwoofer).
SUB VOL (Subwoofer Volume): Adjusts the volume level of the subwoofer output independently.

Start with all volumes at a low setting and gradually increase to a comfortable listening level.

3. Bluetooth Pairing:

Power on the XY-E30H module. It will automatically enter Bluetooth pairing mode, indicated by a flashing LED (if present, not explicitly shown in images but common).
On your audio device (e.g., smartphone, tablet), enable Bluetooth and search for available devices.
Select "XY-E30H" from the list of devices to pair.
Once paired, the LED indicator will typically become solid, and you can play audio from your device through the amplifier.

4. AUX Input Usage:

When an audio cable is connected to the AUX IN port, the amplifier will typically prioritize the wired input over Bluetooth. Disconnect the AUX cable to switch back to Bluetooth mode.

Maintenance

Cleaning: Use a soft, dry cloth to clean the module. Do not use liquid cleaners or solvents, as they may damage the components.
Storage: Store the module in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
Handling: Avoid dropping or subjecting the module to strong impacts.
Ventilation: Ensure adequate ventilation around the module during operation to prevent overheating.

Troubleshooting

Problem	Possible Cause	Solution
No sound output.	No power. Incorrect speaker wiring. Volume too low. Incorrect audio input selected/connected. Bluetooth not paired.	Check power supply connection. Verify speaker polarity and connection to terminals. Increase Master, L&R, and Subwoofer volumes. Ensure AUX cable is fully inserted or Bluetooth is paired. Re-pair Bluetooth device.
Distorted sound.	Volume too high (clipping). Poor audio source quality. Speaker impedance mismatch.	Reduce volume on amplifier and/or audio source. Try a different audio source. Ensure speakers are compatible with amplifier output.
Bluetooth connection issues.	Device too far. Interference. Module not in pairing mode.	Move device closer to the module. Avoid other wireless devices. Power cycle the module to re-enter pairing mode.

Safety Information

Do not expose the module to water, moisture, or extreme temperatures.
Do not attempt to disassemble or modify the module. This may void the warranty and cause damage.
Use only the recommended power supply (DC 9-24V) to prevent damage.
Keep out of reach of children.
Avoid placing the module in high places where it could fall, as indicated on the packaging (refer to Figure 3).
