Treble & Bass Control If You Are Tired of The Inherent High& Low Bass, Why Not Try The High & Low Control Knob! This Will Make You Feel Like Being In A Movie Theater. ANTENNA BASE This is a reserved Bluetooth antenna base. If you place the power amplifier board in a relatively confined metal space, in order to ensure that the Bluetooth signal is not affected, you can weld an additional Bluetooth antenna through this base. Of course, under normal circumstances, there is no need to add an additional antenna, unless the metal box is completely airtight.
