5. Operating Instructions
5.1 Powering On/Off and Volume Control
The ORAMB speakers power on automatically when connected to power. To adjust the volume, rotate the volume knob on the front of the active speaker. The knob also functions as an input selector.
5.2 Input Selection
Press the volume knob to cycle through the available input sources: USB-C, Bluetooth, and RCA. An indicator light will typically change color or pattern to indicate the active input.
5.3 Bluetooth Pairing
- Ensure the speakers are powered on and set to Bluetooth input mode.
- Press and hold the Bluetooth pairing button on the rear panel of the active speaker until the indicator light begins to flash, indicating pairing mode.
- On your device (smartphone, tablet, etc.), navigate to Bluetooth settings and select "Kanto ORAMB" from the list of available devices.
- Once paired, the indicator light will become solid.
5.4 Subwoofer Integration
The ORAMB speakers feature an automatic crossover network. When a subwoofer is connected to the SUB OUT port, the speakers will automatically filter frequencies below 100 Hz, sending them to the subwoofer. This allows the ORAMB speakers to focus on vocal and high frequencies, resulting in clearer sound and reduced distortion, especially at higher volumes.

- Handling: Avoid dropping or subjecting the speakers to strong impacts.
7. Troubleshooting
If you encounter issues with your Kanto ORAMB speakers, refer to the following common problems and solutions:
