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 80¬∞ x 40¬∞ (-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 CQ1 is compatible with Meyer Sound’s RMS remote monitoring system.
