Used CQ-1

CQ-1

The Meyer Sound CQ-1 is a self-powered, phase corrected reinforcement loudspeaker offering precise, low-Q coverage. The CQ-1 features a patented horn design that is the result of extensive research in Meyer Sound's calibrated anechoic chamber. The CQ-1's frequency response of 40 Hz to 18 kHz is uniform over the entire coverage area in both the horizontal and vertical axes, with no side lobes when measured at one-sixth octave frequency resolution.

The CQ-1's low-frequency section comprises a single 15-inch driver, and the high-frequency section utilizes a 4" diaphragm Compression Driver coupled to an 80deg x 40deg (-6 dB points) constant-Q horn.

An integral two-channel class AB/H amplifier with complementary power MOSFET output stages affords total burst output of 1240 watts (620 watts/channel). The field-replaceable amplifier and control unit is equipped with TruPower limiting technology, and the Power Supply incorporates Meyer Sound's Intelligent AC system for fail-safe operation worldwide with no need to manually select the AC voltage.

The compact CQ-1 system is flyable and arrayable using standard aircraft pan ring fittings. An optional QuickFly mounting yoke allows flexible, fast installation and easy aiming in mobile and fixed applications. The CQ-1 is compatible with Meyer Sound's RMS remote monitoring system.

Used Meyer Sound

Established by John and Helen Meyer in 1979, Meyer Sound has been at the forefront of innovation in audio engineering for over two decades. From the outset, Meyer Sound looked beyond loudspeaker cabinet design to create totally integrated, systems-comprehensive solutions that encompass transducer design, signal processing, power amplification and even electroacoustic measurement systems. As a result, Meyer Sound's engineering teams have earned an enviable reputation for developing unique, innovative solutions to some of the most difficult problems confronting audio professionals. In fact, it is fundamental to John Meyer's philosophy that no component of a system should be compromised in order to compensate for variables "upstream" or "downstream." Instead, the entire system should be conceived, designed, tested, confirmed and manufactured as a whole to provide the optimum blend of audio fidelity, utility and long-term reliability.

Used Cabinet Speakers

Speaker cabinets are specially engineered units in which audio equipment such as speakers and their associated hardware are mounted into. These cabinets can be very basic affairs, little more than a wooden case with no additional features other than one port for inputting a sound cable, or they can be incredibly complex cabinets with features ranging from numerous ports and internal baffles to acoustic insulation and composite materials used in their construction. The main point of housing loud speakers and PA speakers in cabinets is not simply to make them look neat and tidy, although that is one benefit. The cabinet actually provides a useful function in preventing competing sound waves from interacting with each other and distorting the end product. This is because the diaphragm that the speaker driver uses to create the sound we hear generates sound waves both at the front and the rear, and these will be out of sync with each other, thus creating a distortion if not dealt with adequately. Other side effects include echo and reverberation, as the sound waves would reach the audience at slightly different times as they travel on different paths through the loud speakers towards them. In addition to minimizing these unwanted side effects, loud speaker’s cabinets also help to manage the vibrations which are caused by the driver frame, as well as the buildup of heat that is associated with amplifiers, driver voice coils and other moving components in PA speakers.
