OTHER FUNCTIONS

Reconnection
bluMe Duo can remember up to 2 devices paired previously, and will attempt to pair with the last connected devices automatically once it is turned back on. bluMe Duo will not initiate reconnection. If bluMe Duo itself is turned off, it is recommended to turn it back on first before turning on the paired devices so that it can accept the incoming Bluetooth connection from the devices.
Adjusting the Volume
bluMe Duo, by design, is a passive transmitter or receiver and has no volume control. User volume level must be adjusted via the input and output sources connected to Blume Duo.
Volume can be individually adjusted on each set of headphones paired with Blume Duo using the built-in volume controls on the headphone. With some TVs and connection options, TV volume may be further raised or lowered to change the volume of all headphones paired with beams. In this case, the volume should be maximized on the TV and then adjusted via headphones for best audio quality.
Factory Reset
With Blume Duo powered OFF, press and hold the MFB for approx. 10secs until the display shows “Reset Device”. The unit will enter pairing mode and any previously paired devices will be cleared from its memory.

TROUBLESHOOTING TIPS

Unable to pair and connect Blume Duo to my Bluetooth device. Make sure you are operating Blume Duo in the appropriate Bluetooth mode.
In TX Mode: Blume Duo can only pair with Bluetooth receiving devices such as Bluetooth headphones, speakers,s or receivers. In this mode, ensure that Blume Duo and the Bluetooth headphone, speaker or receiver are in pairing mode at the same time and are within 1 meter (3 feet) of each other.
In RX Mode : Blume Duo can only pair with a Bluetooth transmitting device such as a smartphone, tablet, or computer. In this mode, ensure that Bluetooth is turned `ON’ on your smartphone, tablet, or computer. Make sure bluMe Duo is ready to pair and your device and Blume Duo are within 1 meter (3 feet) of each other.
My Bluetooth headphone is connected but there is no audio output.

1. Ensure that your audio source (TV) OUTPUT is properly connected to Blume Duo audio INPUT. Audio inputs are used with TX MODE only.
2. Check whether the audio input source is correctly selected on Blume Duo (AUX / OPT). If AUX is selected, make sure your audio source is connected to the AUX input. If OPT is selected, make sure your audio source is connected to the Optical input.
3. Confirm that audio is playing on the TV and the volume is set to “High” on the TV. Make sure that the volume is sufficiently high on your Bluetooth headphone/speaker.
4. If you are using an Optical connection, make sure nothing is connected to the AUX input of Blume Duo.

The smartphone is connected but cannot hear any sound from my audio system.

1. Ensure that your audio source (Home audio system, stereo speakers, etc.) INPUT is properly connected to Blume Duo audio OUTPUT. Audio outputs are used with RX MODE only.
2. Check whether the audio output source is correctly selected on bluMe Duo (OPT / AUX). If AUX is selected, make sure your audio source is connected to the AUX output. If OPT is selected, make sure your audio source is connected to the Optical output.
3. Verify the volume levels on your audio system and player app.
4. If you are using an Optical connection, make sure nothing is connected to the AUX output of bluMe Duo.

The volume output level is Low.
In TX mode: Adjust the volume both on your Bluetooth headphones / speakers and on the TV or other connected device as both may control the volume.
In RX mode: Verify the volume levels on your smartphone / computer OS and player app. Also check the volume levels on your powered speakers or stereo system.
The sound quality is poor and/or the audio is cutting out.

1. For the most noise-free audio, maximize the volume on your audio source (TV, home audio system, powered speakers, etc.) and adjust the volume via Bluetooth-enabled headphones, speakers or smartphone.
2. Make sure you are within range of your Bluetooth-enabled device.
3. Bluetooth devices are susceptible to interference from other Bluetooth devices, cordless phones, routers, microwave ovens, and wireless devices operating on the 2.4 GHz band. Eliminate as many potential sources of interference as possible while using your Bluetooth headphones / speakers.

There is a delay (latency) in audio

1. Bluetooth is a digital wireless signal and there is some latency expected due to the coding/decoding and compression/decompression steps that must occur.
2. The aptX® Low Latency audio codec supported by Blume Duo is notable for having a much lower latency (smaller delay), compared to regular Bluetooth audio.
3. Using Blume Duo with a headphone that supports aptX® Low Latency will minimize audio lag.
4. Some modern TV’s and receivers also have an audio delay option. Make sure that audio delay is set to 0 to minimize lag.
