BLUETOOTH INSTRUCTIONS

• The only control on the amplifier that affects the Bluetooth Audio is the Master Volume, which also affects the volume level of the two physical XLR & 1/4-inch inputs.
• You control the individual level of the Bluetooth Audio, with respect to the two physical amplifier input channels, using the volume controls on the Input Device.
• The range of the Bluetooth connection varies depending on your Input Device and material properties of any walls or barriers between the Input Device and the amplifier. Test the connected range of the Input Device before any performance.

To Connect:

1. Enable Bluetooth on your Input Device and confirm it is not already connected to a device.
2. Turn the volume on the Input Device to the maximum.
3. Turn the amplifier Master Volume to “0”.
4. Remain within 3 feet of the amplifier while attempting to connect the device.
5. Press and hold the Bluetooth button on the amplifier until the blue light flashes. If at this point the light goes from flashing to solid, it means it is already connecting to a device.
6. On your Input Device, look for the Bluetooth device labeled “Circa 74”
7. When the light stops flashing and remains solid blue, the amplifier is connected.
8. On your Input Device, select and play your audio sources, such as a streaming service or audio file.
9. On the Amplifier, slowly increase the Master Volume until you hear the audio source playing on your Input Device.
10. Adjust the Input Device audio source volume with the volume controls on the Input Device.

To Disconnect:

Either:

1. On your input device, follow the device instructions to disconnect a Bluetooth Device.
2. On the amplifier, hold the Bluetooth Button until the blue light shuts off.
