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.
