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.
