Frequently Asked Questions - BLU MKII Chord
How do I pair my BLU MKII with my smartphone?
Ensure the receiver is powered on and in pairing mode (blue LED flashing). On your phone, enable Bluetooth and select Chord BLU MKII from the list. The unit will confirm with a steady LED. You can then stream audio wirelessly.
Does the BLU MKII support aptX for high-quality streaming?
Yes, the BLU MKII supports the aptX codec, providing near-CD quality sound over Bluetooth. It is backward compatible with SBC and AAC codecs.
What audio outputs are available?
The BLU MKII offers both optical (TOSLINK) and coaxial digital outputs, as well as stereo RCA analog outputs, allowing connection to any amplifier, DAC, or active speakers.
How can I connect the BLU MKII to my hi-fi system?
Use the analog RCA outputs to connect directly to your amplifier's AUX input. For even better fidelity, connect the optical or coaxial output to your digital preamp or DAC.
Can I use the BLU MKII with a TV or home cinema system?

Press and hold the pairing button for 10 seconds until the LED flashes red twice. The unit will reboot, and all previously paired devices will be erased.

For best results, enable aptX on your source device (if supported), place the receiver away from RF interference, and use high-quality cables to connect to your amplifier or DAC. Avoid placing the unit on metal surfaces.
