Connection
Wiring
Wire the plugs as shown below. Make sure to use cables specially designed for speakers. When the CZR itself is used in the
Passive mode, wiring to the 2+ and 2– contacts is unnecessary. When the CZR is used in the Bi-amp mode, or when the signals
are sent together with the signal from a subwoofer over a single cable (see “Basic Setting Example” on page 8), make sure to
also wire to the 2+ and 2– contacts.
Parallel Connection of Speakers
[INPUT/PARALLEL] jacks are connected inside in parallel. The first CZR can receive the signal from a power amplifier (hereinaf-
ter, “amplifier”) by one of the [INPUT/PARALLEL] jacks, and route the signal to the second CZR from the rest of [INPUT/PARAL-
LEL] jacks.
When connecting CZR units in parallel, be sure to check the load impedance that the amplifier can drive with. The nominal
impedance of one CZR is eight ohms, and the total impedance of two parallel CZR units is four ohms. In this case, the amplifier
must be able to drive a speaker less than four ohm load impedance.
 Invalid connection
NOTICE
NEVER connect multiple signals from the amplifier to the [INPUT/PARALLEL] jacks simultaneously. This creates a very dangerous
short circuit, possibly resulting in amplifier malfunction.
