Safety Instructions

To prevent fire, electric shock, and damage to the unit, please observe the following safety precautions:

• Do not expose this unit to rain or moisture.
• Do not place objects filled with liquids, such as vases, on the unit.
• Do not block ventilation openings. Ensure adequate space around the unit for proper airflow.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
• Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the unit.
• Only use attachments/accessories specified by the manufacturer.
• Unplug this unit during lightning storms or when unused for long periods of time.
• Refer all servicing to qualified service personnel. Servicing is required when the unit has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the unit, the unit has been exposed to rain or moisture, does not operate normally, or has been dropped.

Setup

Unpacking

Carefully remove the amplifier from its packaging. Retain all packaging materials for future transport or storage. Inspect the unit for any signs of damage. If damage is found, contact your dealer immediately.

Placement

Place the amplifier on a stable, level surface away from direct sunlight, heat sources, and excessive dust or moisture. Ensure there is sufficient ventilation space around the unit, especially around the heat sinks on the sides.

Connections

Before making any connections, ensure the amplifier is turned off and unplugged from the power outlet.

1. Speaker Connections: Connect your speakers to the speaker output terminals on the rear panel. Ensure correct polarity (+ to + and - to -) for each speaker. The AD-2PRO supports 8Ω rated load impedance.
2. Analog Audio Inputs: Connect your audio sources (CD player, streamer, etc.) to the analog input terminals (RCA or XLR) on the rear panel. For balanced connections, use the XLR inputs.
3. Digital Audio Inputs: For digital sources, connect via Coaxial or Optical inputs. The built-in ES9038 decoder will process the digital audio signal.
4. Phono Input: If you are connecting a turntable, use the dedicated Phono input. Ensure your turntable has a compatible output level.
5. Power Connection: Once all audio connections are made, connect the power cord to the amplifier's AC inlet and then to a suitable wall outlet (110V-220V).

Operating Instructions

Powering On/Off

Press the power button on the front panel to turn the amplifier on or off. The display will illuminate when the unit is powered on.

Input Selection

Use the "INPUT" button on the front panel or the remote control to cycle through the available audio inputs (Analog, Digital, Phono).

Volume Control

Rotate the large central knob on the front panel clockwise to increase volume and counter-clockwise to decrease it. The current volume level will be shown on the display.

Mode Selection (Class A / Class A+B)

The AD-2PRO supports both pure Class A and Class A+B operation. Use the "MODE" button to switch between these modes. Note that Class A operation consumes more power and generates more heat (260W-320W static power consumption) compared to Class A+B (70W-110W static power consumption).

Mute Function

Press the "MUTE" button to temporarily silence the audio output. Press it again to restore the sound.

Speaker A/B Selection

If your amplifier is connected to two sets of speakers, use the "SPEAKER A/B" button to select which set is active.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the amplifier. Do not use liquid cleaners or aerosol sprays, as they may damage the finish or internal components.
• Ventilation: Regularly check that the ventilation openings are clear of dust and debris to ensure proper heat dissipation.
• Storage: If storing the unit for an extended period, unplug it from the power outlet and store it in a cool, dry place, preferably in its original packaging.
