For low impedance operation first set the rotary switch to indicate the 4Ω setting. Then remove the terminal cover plate and note the
position of the push-button switch. When the switch is in the “UP” position it indicates that the system is in 4Ω mode. When the switch is
in the “DOWN” position it indicates that the system is in 16Ω mode.
CAUTION: Calculate the total load impedance before connecting the power amplifier. Do not exceed the number of speakers that the
amplifier can drive safely:

MODELS C4-8 / C4-16
The C4-8 and C4-16 are fixed-impedance models offering 8Ω and 16Ω impedance respectively. They are designed for direct connection
to low impedance power amplifiers in applications that require relatively few speakers located in close proximity to the amplifier.
Connect multiple speakers in parallel ensuring that the effective speaker load is compatible with the minimum load impedance of the
connected power amplifier.
