"Most of us are familiar with connecting speakers to a stereo system: you pull the two conductor speaker cable, connect the red wire to the red terminal on the amp, connect the black wire to the black terminal on the amp, repeat on the right speaker, and then repeat on the left speaker. It's all pretty simple and straight forward... and it works great for stereo audio in a single room. But what do you do when you need to distribute audio to speakers in multiple areas? Or if the application won't really support left and right stereo audio? That's where a 70/100 volt (or "70/100v") system comes in... 70/100v amplifiers have a higher signal voltage than conventional stereo audio amplifiers (commonly referred to as "8 Ohm" systems) and allow for more speakers and longer signal distances. This is ideal for any room or building requiring more than two speakers. These systems are commonly used in paging or background music applications, but are a great way to distribute audio anywhere using a very simple wiring concept. The TL-A70-40W provides 40 watts of power and four audio inputs-a microphone input, two analog stereo line inputs), and a digital audio input (typically a CD player, streaming audio player, or other media player). You can select from any of the three line inputs, and mix it with the microphone together into a single audio stream. That audio stream can be broadcast to multiple speakers simultaneously."
