    4 AC Power The AC voltage operating ranges for the CQ Series are 85–134 V and 165–264 V, at 50 or 60 Hz. The CQ Series performs surge suppression for high voltage transients and can safely withstand voltages up to 275 VAC. Continuous voltages above 275 VAC may damage the unit! The Intelligent AC power supply protects the drivers and amplifier c ...

    5 Safety Issues Pay close attention to these important electrical and safety issues. Use a power cord adapter to drive the CQ from a standard 3-prong outlet ( NEMA 5-15R; 125 V max). earth ground chassis ground The CQ requires a grounded outlet. Always use a grounding adapter when connecting to ungrounded outlets. Do not use a ground-lifting adapte ...

    6 Limiting and Protection Circuitry TruPower Limiting ™ System Conventional limiters assume that the resistance of a speaker remains constant and set the limiting threshold by measuring voltage only. This method is inaccurate because the speaker’s resistance changes in response to the frequency content of the source material and thermal variati ...

    7 Fans and Cooling System The CQ uses a forced-air cooling system with two fans to prevent the amplifiers from overheating. A variable- speed primary fan runs continuously with an inaudible operating noise of 22 dBA at 1 m at its slowest speed. The speed of the primary fan begins increasing when the temperature of the heatsinks reaches 4 2 ° C. T ...

Placing the mid-hi speaker more th a n 5 feet from the subwoofer may require setting th e speakers to opposite polarities to compensate for the propagation delay between them. ...

    9 LD-1A with CQ and 650-P Activating the Lo Cut filter on the LD-1A for the Mid-H i output also eliminates the low frequency rise caused by the overlap between the CQ and 650-P. Although a typical CQ : 6 50-P ratio is 2 : 1 , separate Sub and Mid-Hi level controls on the LD-1A allow the ratio to vary while maintaining control of the spectral balanc ...

    10 V erifying Polarity Incorrect driver polarity impairs system performance and may damage the drivers. All Meyer Sound loudspeakers are shipped with the drivers in correct alignment. However, if the driver or circuit wiring has been removed or disassembled in any loudspeaker in a system for any reason, check the polarity between adjacent loudspeak ...

    14 Array Design Creating an effective array with the CQ requires a precise understanding of how to combine the coverage area and SPL of the individual speaker with those of adjacent speakers. Array design is a trade-off between increasing on-axis power and creating smooth transitions between the coverage areas of adjacent speakers. As the splay ang ...
