设置

1. 连接扬声器

The A07 MAX supports passive bookshelf speakers with an impedance of 2-8Ω. Use high-quality speaker cables for optimal performance.

1. Connect the positive (+) terminal of your speaker to the positive (+) speaker output terminal on the A07 MAX.
2. Connect the negative (-) terminal of your speaker to the negative (-) speaker output terminal on the A07 MAX.
3. 确保所有连接牢固，以防止短路。

2. 音频输入连接

Connect your audio source (e.g., phone, tablet, laptop, PC, DVD, MP3 player, TV) to the RCA input jacks on the rear of the A07 MAX using an RCA cable.

3. 电源连接

Connect the provided DC36V 6A power adapter to the DC input port (interface size: 5.5*2.5MM) on the rear of the amp先将放大器置于电源插座上，然后将适配器插入墙壁插座。

4. Stereo/Mono Mode Selection

The A07 MAX features a switch on the bottom of the unit to select between Stereo (BTL) and Mono (PBTL) modes. This allows for flexible usage scenarios, including bridging two A07 MAX units for a powerful mono setup.

Figure 7: Diagram illustrating the correct connection method for two A07 MAX units in mono mode, connected to a pre-amp放大器/DAC。

For mono mode, connect the speaker to the binding posts labeled "+ Mono Mode -" and use the "L" (left) RCA input for the audio signal. If using two A07 MAX units for a stereo mono-block setup, connect the left channel output from your pre-amp to the "L" input of one A07 MAX (set to mono) and the right channel output to the "L" input of the second A07 MAX (also set to mono).

操作说明

1. 电源开关和音量控制

The large knob on the front panel serves as both the power switch and the volume control. Rotate clockwise to turn on the unit and increase volume. Rotate counter-clockwise to decrease volume and turn off the unit.

2. 模式指示灯

Two blue LEDs on the front panel indicate the current operating mode:

• Stereo Mode Indicator: 亮起时 amplifier is set to stereo mode.
• Mono Mode Indicator: 亮起时 amplifier is set to mono mode.

3. Using the 3.5mm AUX Line Output

The 3.5mm AUX line output on the rear panel provides a pass-through from the RCA inputs. This output is not controlled by the A07 MAX's volume knob and can be used to connect to another active device, such as a powered subwoofer or another amplifier for a multi-amplifier 设置。

4. 操作Amp Replacement (Advanced Users)

The A07 MAX allows for the replacement of its Op-Amp小号（操作 Amplifiers) for users who wish to customize the sound signature. The unit is compatible with DIP8 dual op-amps such as OPA2604AP, OPA2134, MUSE01/02/03, LME49720NA, LM4562, AD827AQ, etc. Refer to Figure 6 for the location of the replaceable Op-Amp.

Caution: Op-Amp replacement should only be performed by users familiar with electronic components and proper handling procedures. Incorrect installation can damage the unit and void the warranty.

维护

1. 清洁

为了保持您的外观和功能 amplifier, regularly wipe the exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.

2. 散热

The A07 MAX is designed with efficient heat dissipation through its side and bottom vents. Ensure that these vents are not obstructed when placing the amplifier. Adequate airflow is crucial for optimal performance and longevity of the device.
