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

 

Thanks dear.

Hi,
I have the same question and I am not sure which position I must choose on the DIP switch. I want the BTL option for 8 ohm mono speaker. Do I have to switch both of these switches on the side of letter B?
Thanks

Thanks for explaining those two acronyms. I might have eventually guessed BTL, but never guessed OCL.
