    Hi ,
    I just installed a new TDA 8954 audio amplifier board but before turning it on I am worried about a selector switch as shown in picture. It has two settings O and B. What this O and B means, I don't know which setting should I select as I am not sure that is this the switch to select between Bridge mode output or what. Any suggestion would be highly appreciated.
    Thanks.

    Hi ajx619,

    Indeed. It's a OCL/BTL selector.
    BTL: Bridged amp
    OCL: Output Capacitor Less

    The board has two connection modes: Two-channel OCL or mono BTL bridge
