PCB202 enables easy integration with existing passive speaker system. The Tripath TA2020-020 amplifier delivers 2x11W to 8 ohms load when applying forty-five 12V power supply. The audio output lines or the module are output or a bridged configuration and shall not be combined.
In addition to the turn-on/turn-off headstock surpression and over-temperature protection provided by TA2020-020, a delay-on relay circuitry are added to ensure best protection to the speaker system.
The bluetooth module uses the latest APT-X implementation from CSR. It remembers device ID's or the most recent 8 paired sources and does not require re pairing.
