Crown D-45

Imagens Grandes

Os D-45 e D-75A são perfeitos para aplicações de potência moderada, como monitoramento de campo próximo em estúdios de gravação ou broadcast, monitoramento de áudio em salas de vídeo, amplificador de fone para gravação/broadcast ou um pequeno sistema de paging.

Projetados, construídos e cuidadosamente verificados para garantir operação confiável com uma ampla variedade de cargas, os amplificadores Crown D Series são resfriados por convecção. Sua alta confiabilidade é particularmente importante na redução dos custos de manutenção.

Recursos

Your dual-channel (stereo) amplifier can optionally be configured to deliver double the power from a single (mono) channel. It also provides the following features:

•Powerful AB+B class circuitry yields maximum efficiency with minimum crossover “notch” distortion.

•IOC® (Input/Output Comparator) alerts of any distortion that exceeds 0.05% to provide proof of distortion-free performance.

•Signal presence indicators verify the presence of amplifier output.

•Detented level controls for precise repeatability.

•Ultra-low harmonic and intermodulation distortion result in the best dynamic transfer function in the industry.

•Very low noise and wide dynamic range.

•High damping factor provides exceptional loudspeaker motion control.

•Convection cooling system eliminates fan noise and maintenance.

•Mounts in a standard 19-inch (48.3-cm) rack.

•Front-panel headphone jack.

•Three Year, No-Fault, Fully-Transferable Warranty completely protects your investment and guarantees its specifications.
