Toshiba Launches Power Amplifier For Car Audio With Strong Resistance To Power Surges  – Sep 26, 2018 – Tokyo, Japan (Techreleased) – Toshiba Electronic Devices & Storage Corporation has launched a new 4-channel power amplifier for car audio, “TCB503HQ” that delivers strong resistance to power surges. Sample shipments start today with mass production scheduled to begin in the first quarter of 2019.

Building on Toshiba’s proven development capabilities in ICs for car audio, the new product achieves a higher reliability with an analog fine process resistant to power surges. It also supports 6V operations suitable for vehicles equipped with idling reduction systems, which have become popular in recent years. This feature suppresses popping sounds that occur when power voltage fluctuates.

Other features include a built-in filter to improve resistance to extraneous high-frequency noise, and to prevent generation of abnormal noise even when there is high-frequency noise from mobile phone radio waves and adjustment of door mirrors.

Using the clip detection signal to control the volume and tone control circuit, the sound quality of the set can be improved.
