Parallel connection of speakers
[INPUT/PARALLEL] connectors are connected inside in parallel. The first CHR receives the signal from an amplifier (such as a
power amplifier, a powered mixer, etc.) by one of the [INPUT/PARALLEL] connectors, and routes the signal to the second CHR
from the rest of [INPUT/PARALLEL] connectors.
When connecting CHRs in parallel, be sure to check the load impedance the amplifier can drive. The nominal impedance of one
CHR is eight ohms and the total impedance of two parallel connected CHRs is four ohms. In this case, the amplifier must be
able to drive less than four ohm load impedance.
Amplifier
Invalid connection
Do not connect the input from the amplifier to both the [INPUT/PARALLEL] connectors simultaneously. This creates a dangerous
short circuit.
