Meyer Sound CQ-1 Powered Loudspeaker
Meyer Sound CQ-1 Powered Loudspeaker
The CQ-1 wide coverage main is a selfpowered, phase-corrected reinforcement loudspeaker offering precise, low-Q coverage. The CQ-1 features a patented constant-Q horn design — the result of extensive research using Meyer Sound’s calibrated anechoic chamber. The frequency response of 40 Hz to 16 kHz is uniform over the entire coverage area in both the horizontal and vertical axes, with no side lobes even when measured at a one-sixth octave frequency resolution.
Features:
- Wide and narrow overage patterns for CQ-1 (low Q)
- Self-contained control electronics, amplifiers, and drivers
- Dual-channel 1240 Watt amplifier (620 Watts per channel)
- Active balanced input circuit
- Active crossover with optimized pole-zero filter combinations
- Intelligent AC™ System
- TruPower™ Limiting (TPL)
- Compatible with the Remote Monitoring System™ (RMS)
