on the CPM-300 and any connected equipment.
2.Speaker Connection Terminals (Binding Post, Standard Phone Type)
These are the jacks and terminals for connecting the speakers. Two systems may be connected simultaneously.
Minimum recommended load impedance for the CPM-300's power amp is 4 ohms.
<Combining Speakers>
Nor Be sure to check the combined impedance when connecting multiple speaker pairs.
When connecting multiple speakers in parallel:
(Ex.) 8 ohms/8 ohms — 4 ohms YES
6 ohms/8 ohms > 3.40hms NO
6 ohms/6 ohms — 3 ohms NO
4 ohms/4 ohms —> 2 ohms NO
"Although the CPM-300 is protected from damage by the PC Control Circuit, take care not to
connect speakers of less than 4 ohms impedance or to allow shorting in the speaker cables
<About the PC Limiter Circuit>
MEMO The PC Limiter Circuit works to protect the CPM-300 if the + and - wires of the speaker cable are
shorted or if speakers with impedance of less than 4 ohms are used; this may result in no sound
from the speakers or distortion.
