Unique to the BR13 is the ability to upsample low sampling rate audio signals to high sampling rates up to 96kHz/24bit using any input*, allowing you to get even closer to master- level sound quality.
*Some older devices may only support 48kHz input, for which a compatibility mode can be selected in the app for use with these devices
*44.1kHz is currently upsampled to 88.2kHz
*Bluetooth upsampling not available
