- Bluetooth® playback compatible with aptX®/AAC codecs for low latency and high definition (VL-S3BT)
- A Bluetooth® receiver is built into the cabinet, making wireless playback possible from a smartphone, PC, or any Bluetooth®-enabled device where the reference sound is saved. Bluetooth® playback supports aptX® and AAC codecs - higher definition and lower latency than the typical SBC codec. So, without any cables, the sound can be compared to the sound in production - resulting in high-definition playback which does not feel wireless. Switching input and pairing can be done using the buttons on the front side of the body.
Music playback over Bluetooth®
Transmission protocols, called profiles, are standardized for the purpose of wireless transmission via Bluetooth®. VL-S3BT uses the profile A2DP (Advanced Audio Distribution Profile), and can wirelessly play back from devices compatible with A2DP.
Furthermore, the sound is compressed for wireless transmission. This compression method is called "codec." Confirm which codec your device is compatible with on the webpage describing your device.
Codecs supported by VL-S3BT
SBC (Sub Band Codec): This is the standard codec which all A2DP-compatible equipment support. It is higher in definition than a headset mic, for example, but is inferior to the codecs described below. Also, latency occurs at the time of compression, so a time lag may be felt when listening to a video or the like.
AAC (Advanced Audio Codec):This is the codec used mainly in iPhones and other iOS devices. The time lag is negligible. The compression rate is on par with SBC, but has superior definition.
aptX®: The compression rate is low, allowing for playback in high definition - closer to the original sound. The time lag is also negligible.
