Wiring
Make sure to wire the plugs as shown below.
❚ ❚
Phone plug
Parallel connection of speakers
The signals of the phone jack and speakON connector are connected in parallel. The first CBR receives
the signal from an amplifier (such as a power amplifier, a powered mixer, etc.) with the phone jack or the
speakON connector, and routes the signal to the second CBR. When connecting CBRs in parallel, be sure to
check the load impedance the amplifier can drive. The nominal impedance of one CBR is eight ohms and the
total impedance of two parallel connected CBRs 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 phone
jack and the speakON connector
simultaneously. This creates a
dangerous short circuit.
