6. Setup and Connections
Follow these steps to set up your AIYIMA A07 MAX and T3 PRO:
6.1 Connecting the AIYIMA T3 PRO Phono Preamp
- Ensure both the T3 PRO and A07 MAX are powered off and unplugged.
- Connect your turntable's RCA output cables to the MM/MC Phono Input on the rear of the T3 PRO.
- Connect your turntable's ground wire to the GND Terminal on the T3 PRO.
- Connect the Audio Output (RCA) of the T3 PRO to the RCA Audio Input of the A07 MAX amplifier using RCA cables.
- Connect the AC12V power adapter to the Power Input (AC12V) of the T3 PRO. Do not plug into a wall outlet yet.
6.2 Connecting the AIYIMA A07 MAX Amplifier
Figure 6.1: Connection diagrams for AIYIMA A07 MAX in Stereo and Bridge Mono modes.
- Select Operating Mode: Before connecting speakers, decide whether to use the A07 MAX in Stereo or Bridge Mono mode. Locate the Stereo/PBTL Mono Mode Switch on the bottom of the A07 MAX and set it accordingly.
- Connect Speakers (Stereo Mode): If in Stereo mode, connect your passive speakers to the Speaker Output (L/R) terminals. Ensure positive (+) terminals on the amplifier connect to positive (+) terminals on the speakers, and negative (-) to negative (-).
- Connect Speakers (Bridge Mono Mode): If in Bridge Mono mode, you will typically use two A07 MAX units for a stereo setup, with each unit driving one speaker. For a single A07 MAX in mono, connect a single passive speaker to the designated mono output terminals (refer to Figure 6.1 for specific wiring).
- Connect the DC 24-48V power adapter to the Power Input (DC 24-48V) of the A07 MAX. Do not plug into a wall outlet yet.
6.3 Powering On
- Once all audio connections are secure, plug both power adapters into their respective wall outlets.
- Turn on the AIYIMA T3 PRO using its front panel ON/OFF switch. The power indicator will illuminate.
- Turn on the AIYIMA A07 MAX by pressing its volume control knob. The mode indicator (Stereo or Mono) will illuminate.

9. Troubleshooting
- No Sound:
- Ensure both units are powered on and their respective power indicators are lit.
- Check all audio cables (RCA, speaker wires) for secure connections and correct polarity.
- Verify the A07 MAX is in the correct Stereo or Mono mode for your speaker setup.
- Increase the volume on both the T3 PRO and A07 MAX gradually.
- Confirm your turntable is functioning correctly and its output is connected to the T3 PRO's phono input.
- Humming or Buzzing Noise:
- Ensure the turntable's ground wire is securely connected to the T3 PRO's GND terminal.
- Check for loose cable connections.
- Move audio cables away from power cables to reduce interference.
- Test different power outlets.
- Distorted Sound:
- Reduce the volume on both units.
- Adjust the Gain Control on the T3 PRO. If the gain is too high for your cartridge, it can cause distortion.
- Ensure your speakers are correctly connected and not overloaded.
- Unit Overheating:
- Ensure adequate ventilation around both units. Do not place them in enclosed spaces.
- Check that the impedance of your speakers matches the amplifier's specifications.
10. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the units. Do not use liquid cleaners or solvents.
