In this mode, the LB-DAC serves as an optical audio decoder and Bluetooth transmitter. It can be used to convert the optical digital audio from a TV, Game Console, or PC into analog stereo and send it to stereo systems, wired headphones, or transmit it wirelessly to Bluetooth headphones or speakers. The possible connections are as shown below: In this mode of operation, the LB-DAC input and output flow is as follows: • Optical digital audio input from a source such as a TV, Game Console. • The optical digital audio is decoded into analog audio and output over the RCA analog stereo output as well as the 3.5mm AUX audio jack for use by a stereo system or wired headphones. • The audio is transmitted wirelessly using Bluetooth to headphones or speakers. • The optical digital audio is passed through to the Optical output jack, and can be sent to a stereo system or sound bar for playback. • The decoded analog audio is also output over the RCA analog stereo output as well as the 3.5mm AUX audio jack for use by a stereo system or wired headphones. • Audio playback volume can be adjusted using the volume control knob.

In this mode, the LB-DAC serves as an Bluetooth transmitter that accepts analog audio from a stereo system, phone, tablet, or PC, and transmit the audio wirelessly to Bluetooth headphones or speakers. The possible connections are as shown below: In this mode of operation, the LB-DAC input and output flow is as follows: • Analog audio input from a source such as a stereo system, phone, tablet, or PC. • Analog audio input can be connected to the RCA or 3.5mm AUX jacks. • The audio is transmitted wirelessly using Bluetooth to headphones or speakers. • Audio volume for the analog audio input cannot be adjusted using the LB-DAC’s volume control knob, and can only be controlled from the analog audio source. • The optical audio decoder continues to function in this mode, and any optical digital audio will be decoded and mixed together with the analog audio input. • The optical digital audio is passed through to the Optical output jack, and can be sent to a stereo system or sound bar for playback.

For additional troubleshooting resources, visit our product information website www.miccatron.com, or email technical support at support@miccatron.com for personalized assistance. Optical digital audio has no sound or sounds like static The LB-DAC supports PCM audio up to 192kHz 24-bit, it does not support Bitstream, Dolby, or DTS. Most TVs, game consoles, PCs, DVR machines, and DVD/BD players have a setting for configuring the optical audio output format, refer to their user’s manual for instructions on how to change the optical audio setting to PCM. Optical digital audio has sound, but contains breaks and pops Check to see if the red “ERROR” light on the LB-DAC flashes when the breaks and pops in sound occurs. If this happens, it’s most likely that the optical audio cable is not making a good connection. Check the following: • Make sure that the optical cable jack is securely inserted on both ends. • Use a good quality cable that is no longer than 15 feet. • Check to see if the connectors on the optical cable are damaged in any way. Bluetooth does not pair with a device The LB-DAC is a Bluetooth transmitter and can only be paired with devices that receive sound, such as headphones and speakers. It cannot be paired with other transmitter devices such as a cellphone, tablet, or computer. The LB-DAC supports standard pairing passkeys of 0000, 1111, 1234, and 8888. Ensure that the Bluetooth headphone or speaker uses one of these passkeys. Once the LB-DAC enters pairing mode, it takes up to 60 seconds for the pairing to complete. Please wait for at least 60 seconds before giving up. Try turning the LB-DAC off and back on and retry the pairing process. Make sure that no other Bluetooth device is turned on in the vicinity except for the LB-DAC and the headphone or speaker that it is attempting to pair with. Bluetooth does not reconnect with a device The LB-DAC remembers up to 8 devices that it has been paired with, and can connect with any two at the same time. To reconnect a particular device with the LB-DAC, make sure that other Bluetooth headphones or speakers are turned off. Please also try the following steps: • Short press the Bluetooth button on the LB-DAC to initiate reconnect attempt. • Turn the LB-DAC off and back on. • Initiate reconnect attempt on the Bluetooth headphone or speaker – please refer to the headphone or speaker’s user manual on how to initiate a reconnection. • If the reconnect still fails, try paring the LB-DAC with the device again – this should not be necessary, but is the option of last resort if the previous steps have failed.
Copyright © 2009-2018 Micca. All rights reserved. Page | 6 There is a noticeable audio delay using Bluetooth The LB-DAC supports APTX Low Latency operation, which requires that the receiving device also supports APTX Low Latency. Check to ensure that your Bluetooth headphone or speaker does in fact support APTX Low Latency operation. The APTX Low Latency feature is only available when the LB-DAC is connected with one device. When it is connected with two devices at the same time, there will be more noticeable latency due to the limitations of the APTX technology. In all cases, with or without APTX Low Latency, the audio delay can be minimized by ensuring that there is a clear and strong Bluetooth connection. Try to shorten the distance between the LB-DAC and the receiving device, and avoid any obstructions in the way. The volume knob does not function When the LB-DAC is used in Input Mode, the volume knob does not control the analog audio volume that comes in through the RCA or AUX input jacks. Please use the volume control on the audio source to control the audio volume. While in Input Mode, the optical digital audio input feature of the LB-DAC still functions, and the volume of the decoded audio is controllable using the volume knob. This decoded audio will be mixed together with the analog audio input and transmitted over Bluetooth. Note: All the information contained in this manual was correct at the time of publication. However, as our engineers are always updating and improving the product, your device’s software may have a slightly different appearance or modified functionality than presented in this manual.
