Description
The Crest Audio CPX 4 is a two-channel power amplifier for portable sound and installed systems. Its GCL gain-comparator limiting monitors input/output behavior and reduces the signal under distortion or excessive-current conditions. A 100 Hz Linkwitz-Riley crossover and 40 Hz low-cut filters provide onboard signal shaping, with channel-level switching for the supported filter functions. Daisy-chain outputs help route a source to additional equipment. Use the exact model’s output and operating-mode specifications when matching cabinets; stereo and bridged connections have different load requirements.
Features
- Two-channel power amplifier
- GCL gain-comparator limiting
- 100 Hz Linkwitz-Riley crossover
- 40 Hz low-cut filters
- 1/4-inch daisy-chain outputs
- Stereo/bridge mode selection
Why We Like This
Independent filter selection is useful when a simple amplifier rack needs dedicated low-frequency channels. The limiting system adds protection while the operator keeps the load and gain structure appropriate.
FAQs
Q: How do I choose the speaker load?
A: Use the specified minimum impedance for the selected operating mode and account for all connected cabinets.
Q: Are burst and continuous power ratings interchangeable?
A: No. Compare ratings with the same impedance, distortion, bandwidth, and test conditions.
Q: Can I connect a microphone directly?
A: A power amplifier normally needs a suitable line-level signal from a mixer, preamp, or processor.
