Press the Bluetooth, OPT, LINE or AUX button on the remote or the volume knob to choose the desired audio source. Control the playback via the remote control by pressing the buttons. Note: The amplifier will shut off automatically if the temperature exceeds 85°C, to indicate this the Power indicator will turn orange. The amplifier will re-start automatically when the temperature has dropped below 60±10°C. Bluetooth Pairing: 1. Press the Bluetooth on the remote (or push the selector button) to activate the Bluetooth source. 2. Activate Bluetooth on your phone/tablet and start searching for new Bluetooth devices. 3. When y our phone/tablet finds the Tangent Ampster B T II, choose this unit and begin pairing up. (You can force the Ampster into pairing mode, with long press on BT) Remote control: Connect: (UK) 4 5 1 3 2 9 7 8 6 Connect Your Device: Connect your loudspeakers to the Speaker Output. Make sure you connect the -/+ and the L/R cables to the correct input. Connect your subwoofer to SUB out. Connect a CD player or other device via its RCA cable to the RCA L/R input. Make sure you connect the “L” plug to the left input channel and the “R“ plug to the right input channel. Connect your phone/tablet/MP3 via an AUX cable to AUX Input. Use the optical input by connecting a device using a optical fiber cable to the Optical Input. Note: Remember to change into the desired source on the amplifier.
