Neutrik speakON plug (NL4) 2– (unconnected) 2+ (unconnected) 1+ : 1– : 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.
Installation Examples CAUTION • Before doing any installation or construction work, consult with your Yamaha dealer. • The installation should be checked thoroughly at regular intervals. Some fittings may deteriorate over extended periods of time due to wear and/or corrosion. NOTE Wires can be attached to the screw holes for eye bolts and to the screw holes for the U-bracket (CHR10 only) located at the center of the handle. The illustration below is an example of using the Ubracket.
Installation Examples Suspension angle The strength of an eye bolt differs depending on the suspension angle. Make sure to use eye bolts within a range of 0 to 45 degrees from a right angle (as shown). Correct: Within 45° from a right angle Max. 45° 0° 45° Incorrect: Do not suspend the eye bolts as shown in the illustrations below.

Troubleshooting Symptom No sound. Howling sound is produced (feedback). Possible causes The cable is not connected properly. A microphone is directed toward the speaker. Aim the speaker away from the area where the microphone picks up sound. The sound is amplified too much. Lower the volume of input device and locate the microphone more closely to the sound source. The total impedance of the speakers is less than the minimum load impedance of the amplifier. The amplifier shuts down.
