Operating Instructions

1. Initial Start-up

1. Turn down the total volume.
2. Turn down the zone volume.
3. Connect the stereo amplifier to the power supply and turn it on until the power indicator is lit.
4. Turn the total volume to the optimal level.
5. Adjust the zone volume to the desired output level. Disconnect the power cord before changing wiring or installation.

2. Mic Broadcast

The system detects microphone voice and mutes other audio sources. When there is no microphone signal, it reverts to the original playback state.

3. Bluetooth Mode

Press the MODE button until "Bluetooth" is displayed. Open Bluetooth on your phone or device and find "6 ZONES AMP BT" for pairing. Music can then be streamed wirelessly. The digital display stops flashing upon successful pairing. Wireless transmission distance is approximately 10m.

4. USB Mode

Upon inserting a USB, the device enters USB mode (plug and play). The display shows the current song name, duration, playing mode, status, and volume level. Short press the LOOP button to switch between random play, single loop, and directory loop.
