You can also connect multiple speakers with a different rated input to a single channel. For example, you can connect
ten speakers with a rated input of 5 W and ten speakers with a rated input of 10 W (total 150 W), as shown below:

Note: Be sure to use speakers that support the XH150’s line-out voltage (70 V or 100 V).
Note: You cannot connect a low-impedance speaker directly to the XH150. In this case, be sure to use a
speaker transformer (such as the Yamaha ST15). Follow the instruction guide that came with the speaker
transformer to avoid excessive loads.
