CXS series Owner’s Manual 7ConnectionWiringWire the plugs as shown below. Use cables specially designed for speakers. When using only the CXS itself, wiring to the 2+and 2– contacts is unnecessary. When the signal to a full-range speaker, or the signal for cardioid mode are sent together overa single cable using the [OUTPUT] jack, make sure to also wire to the 2+ and 2– contacts. (See “Basic Setting Example” onpage 8, and “Cardioid Mode Setup” on page 9.)Parallel Connection of Speakers[INPUT/PARALLEL] jacks are connected inside in parallel. The first CXS 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 CXS from the rest of [INPUT/PARAL-LEL] jacks.When connecting CXS units in parallel, be sure to check the load impedance that the amplifier can drive with. The nominalimpedance of one CXS is eight ohms, and the total impedance of two parallel CXS units is four ohms. In this case, the amplifiermust be able to drive a speaker less than four ohm load impedance. Invalid connectionNOTICENEVER connect the multiple signals from the amplifier to the [INPUT/PARALLEL] jacks simultaneously. This creates a very danger-ous short circuit, possibly resulting in amplifier malfunction.When using only the CXS itself.
