Getting Started

Connecting 318BT for the first time

318BT can be connected directly to any XLR input (MIC Level), but before connecting; it is a good practice to ensure the Phantom Power is turned OFF on the input jack where 318BT is to be connected.

Inserting 318BT while the Phantom Power is ON may trigger a protection circuit that turns OFF the 318BT for 60 seconds, please see the troubleshooting section.

Insert 318BT into the input XLR and turn ON the Phantom Power supply, a red LED will start to blink, allow red LED to blink for 30 seconds before connecting a device.

After 30 sec, both Red and Yellow LEDs will blink, this means the device is ready to be paired, turn on the Bluetooth connectivity on your device (Phone, PC, tablet …etc.) and connect to the 318BT with the name Switchcraft 318BT.

To skip the waiting period for the 318BT to be paired, press the Reset button using a paper clip, yellow and red LED’s will blink, allowing 318BT to pair with other devices.

Troubleshooting

FAQ’s

Q: Why doesn’t the dongle work when plugged into my mixer?A: Plugging the dongle when the Phantom Power “ON” may trigger a protection circuit, remove the dongle from the mixer, turn “OFF” the Phantom Power, wait for 60 seconds and try again.

Q: Why is the audio output level so low?A: Raise the volume on your source device (phone, tablet, etc.…).

Q: Why does the dongle have a red LED blinking and I cannot connect to the dongle though I waited for more than 30 Sec?A: Continuous red blinking LED is mostly caused by losing connection to the source, for example if the operator left the room with the phone or tablet and the connection was compromised, connection can be restored by resetting the 318BT using the Reset button.

Q: Why doesn’t the dongle work on Phantom Power while working well on USB power?A: The Phantom Power on your mixer has to be greater than 46.5V.

Q: I cannot get a good range! The audio starts breaking with less than 100’ distance! Why?A: The human body blocks the high frequency Bluetooth® signal, if you are using a Smartphone, it is not recommended to put it in your pocket while streaming, also Line-Of-Sight operation will enhance the range.

Q: Can I connect the Dongle to a Bluetooth® speaker or headphone?A: No, the unit only acts as “Slave” and can only be connected to a “Master” device (Phone, tablet, PC…etc.).
