The AK-BT1 is a Bluetooth adapter designed for compatible TASCAM recorders that enables wireless control through a dedicated control app on a smartphone, tablet, or PC. It adds Bluetooth connectivity using Bluetooth Low Energy (BLE) technology, supporting stable pairing and operation within an approximate 10 meter range while maintaining efficient power use. This adapter allows users to manage recording functions remotely, reducing the need to touch the device during operation and supporting workflows such as field recording, studio setups, and video production. Designed for models including Portacapture X6, Portacapture X8, and DR-10L Pro, it functions as a compact and lightweight Bluetooth module for recording equipment control. The AK-BT1 supports wireless timecode synchronization on compatible devices and is intended for control purposes only, with no audio transmission.
