Crest P4000 power amplifier.

Crest P4000 power amplifier

The Professional Series power amplifiers exemplify Crest Audio's heritage by offering true reliability and excellent performance. This results from Crest's no-compromise approach in electrical design and mechanical construction. Only the highest-grade components are used in the modular sub-assemblies, mounted in ultra-strong steel chassis.

The P4000 (shown) has exactly the same spec as the P4001 but benefits from a 20 segment LED peak reading VU meter per channel covering a range of -57dB to 0dB.
