Safety Precautions Use Caution to Prevent Hearing Loss JK Audio products are designed for the broadcast industry. The broadcast professional must be able to hear headphone signals over the ambient noise level. From the cheering crowd at a football game to trackside at a car race, the program material or cues must be heard at high volumes without distortion. Road Safety Never use headphones while driving or cycling, etc. It can be dangerous to turn up the volume even while walking.

Getting Connected Intercom Audio In bridging mode, Interloop provides minimal loading to the intercom audio line, typically >15k ohms impedance. In talk mode, a soft start solid state relay engages audio transmission with a nominal 200 ohms output impedance into the intercom line. A temporary loss in intercom power will automatically release the solid state talk relay even if the 9V battery backup is installed.
Configuring your Interloop XLR connections 2. Remove the battery drawer. Audio Channel Selection 4. Carefully slide the battery housing out from the aluminum chassis, just enough to allow access to the circuit board. The battery box wiring will remain connected during this operation. Pin 1 = Common Pin 2 = Intercom Power (optional power + audio) Pin 3 = Audio (default) An internal slide switch selects either Pin 3 or Pin 2 as the audio channel.
Bluetooth Wireless Technology Bluetooth Status LED The blue LED on the front of the unit flashes in different sequences to indicate the current connection status. When attempting to put the unit into Pairing mode, you should power the unit off then hold the Pair button as you're turning the unit on. If you put the unit into the wrong state due to releasing the button at the wrong time, holding it again for "X" seconds will not put it into the desired mode.
Bluetooth Wireless Technology Pairing to a Cell Phone with Bluetooth Wireless Technology When you're first connecting to a new device, you should be in an environment with no other Bluetooth wireless technology enabled devices within range that might also be in Pairing Mode. 1. Starting with the Power switch Off, set the Phone/Headset switch to the Phone position. 2. Press and hold the Pair button on the Interloop while turning the Power switch On. Hold the Pair Button for 5 full seconds.
Bluetooth Wireless Technology Pairing to a Headset with Bluetooth Wireless Technology When you're first connecting to a new device, you should be in an environment with no other Bluetooth wireless technology enabled devices within range that might also be in Pairing Mode. 3. Press and hold the Pair button on the Interloop while turning the Power switch On. Hold for 5 full seconds. After you release the Pair button, the blue LED should flash rapidly if Interloop is in Pairing Mode. 1.
Bluetooth Wireless Technology Connection History Interloop retains a history of the 16 most recent devices. To clear the connection history and return to factory reset, hold the Pair button in for at least 20 seconds. After resetting, Interloop will return to Pairing Mode. Disconnecting from a device with Bluetooth Wireless Technology Since Interloop has no other function when Bluetooth is powered down, you may simply turn off the Power switch to disconnect from the Bluetooth device.
Bluetooth Wireless Technology Reconnecting to a Device When reconnecting to a device that is still in Interloop’s pairing history, the device that will be in Headset mode should be powered up first and both devices should be in Idle Mode. When the Master device is turned on, it will find the Headset device during its power up cycle. Switching Between Phone and Headset The Role Select switch is only monitored during the power-up sequence.
FAQs What is the range of the Bluetooth transmitter/ receiver? Interloop will transmit and receive audio signals up to 40 feet (12 meters) from your Bluetooth device. The actual range is limited to the device with the shortest range. Transmitting signals over longer distances will require more power, therefore you should keep Interloop as close as possible to your Bluetooth device to conserve battery power.
FAQs Can I use my Bluetooth headset with my cell phone while I have my phone connected to the Interloop? No, your cell phone can only be connected to one Bluetooth enabled device at a time. My Interloop won’t pair with my cell phone. Why won’t it accept the PIN? If this is the first time you have paired the Interloop with this cell phone, make certain you are in Pairing Mode and not Idle Mode. You must press and hold the Pair button on the Interloop while turning the Power switch On.
