Connecting Speakers - Yamaha 150 Owner's Manual

Connecting Speakers

The XH150 series enables you to connect multiple high-impedance speakers in parallel that support 70 V or 100 V
line output. The number of speakers that can be connected varies depending on the speakers' rated input. You can
connect speakers with a total rated input per channel of up to 150 W.
Total rated input of up to 150 W
For example, if you are using speakers with a rated input of 15 W, you can connect up to ten speakers. If you are
using speakers with a rated input of 10 W, you can connect up to 15 speakers. You may also connect speakers with a
different rated input for each channel, as shown below:
