Crest Audio Professional Audio Equipment

Crest Audio manufactures power amplifiers and mixing consoles for live sound and installed audio systems. Its equipment is designed for concerts, events and other venues, where the amplifier is selected to match the loudspeakers' power handling, impedance and the purpose of the system.

Stage IQ offers Crest Audio CPX and Pro-LITE power amplifiers. These series provide a choice of power ratings and designs for portable and permanently installed sound systems.

Crest Audio Pro-LITE Power Amplifiers

The Pro-LITE series uses Class D amplification and a switch-mode power supply. This design reduces equipment weight, making these amplifiers suitable for systems that need to be transported and set up regularly at different event venues.

The range includes Pro-LITE 3.0, 5.0 and 7.5 models. When choosing an amplifier, compare its output power at the impedance of your loudspeakers and in the intended operating mode.

Crest Audio CPX Power Amplifiers

The CPX series is designed for portable and installed sound systems. It includes the CPX 1, CPX 2, CPX 3 and CPX 4 models, allowing you to select an amplifier to suit your system's power requirements.

CPX amplifiers feature built-in signal limiters and filters for use with loudspeakers and subwoofers. Each model's connections, filter settings and operating modes are listed in its product description.

How to Choose a Crest Audio Amplifier

Start by checking the loudspeakers' nominal impedance, power handling and the number of speakers connected to each amplifier channel. Compare amplifier power ratings at the same load: the rating at 4 Ω differs from the rating at 8 Ω. Also check the minimum load the chosen model supports in the intended operating mode.

For a portable system, amplifier weight and ease of transport matter. For rack installation, check the chassis dimensions and ventilation requirements. Stage IQ can help you select a Crest Audio model to suit your loudspeakers and intended use.
