QUESTIONS & ANSWERSAsk a Question
Will this amp work with two NS-AW 294 YAMAHA speakers?
You need stereo 8 Ohms receiver. PCM60A is a 70volt amp
Can I use this with 6 70v speakers in series as long as I don't exceed the total 100watt maximum
Every 70-volt speaker has a selection of Watts depending on the number of speakers you want to use.
On the speaker transformer you will find:
Ex. 2.5, 5. 15, 10, 25, 30, 50 Watts
Ex. you are using a 70 volts, 100 watts Amplifier and you wish to use 10 speakers
On the speakers, you will choose the 10 watts tapping and connect them all in parallel to get a total of 100watts. Now it really doesn't have to be exact.
In your case, you only need six, so if you divide 100 watts over six speakers, you get around 17 Watts allocation per speaker but checking your speaker you only have 15 watts as the closest Wattage. You can actually use that as your tapping.
I want to purchase the PCM60A for a 70 volt install but my customer doesn't want streaming
You can purchase a separate amplifier for streaming since you have an option not to use this unit for streaming purposes.
