Think about buying an aerial with a built-in signal amplifier, especially if the television set is more than 20 feet (six metres) away.

特别是如果电视机与天线距离超过超过20英寸(6米)，就得考虑买一个内置信号放大器的天线。

However, either amplifier can be used with a surround sound processor if the processor has the capability of routing the unprocessed signal through when it is turned off.

然而，无论是放大器可与环绕声处理器，如果处理器具有路由的未加工的信号通过能力时，是关闭的。

The experiment shows that if the current amplifier factor is big, Junction J_3 is hard and the ineffective trigger branch current is low, the turn-on time can be shorten effectively.

实验结果指出，器件的电流放大系数器件大j、3结特性硬，无效触发分流小，可有效地缩短开通时间。

Setup is straightforward, although you may have to do some running back and forth between the hefty (they include an amplifier) white ZonePlayers if you're doing it alone.

That old piano is a big part of the appeal: Its tinny sound is run through a 1950s amplifier, adding layers of fuzz and grit, so it's as if you're listening to a very old recording of a very new song.
