The speakers used must be able to handle more than
50 W of audio power. If using optional audio power,
the speakers should be able to handle the maximum
amplifi er output power. Speakers with low input ratings
can be damaged.
Speaker impedance should measure 4 – 8 , which is
typically marked on most speakers. Lower or higher
impedance speakers will affect output and can cause
both speaker and this unit damage.
