4-channel amplifier 250w per output channel
CA4250 (PZA)
The Cloud CA series is a range of versatile, advanced-design multi-channel audio power amplifiers capable of directly driving low-impedance loudspeakers or high-impedance speaker distribution systems (100 V line or 70 V line). They are ideal for sound reinforcement applications in the retail, leisure, hospitality, commercial, and industrial sectors.
The CA2500, CA4250, CA6160, and CA8125 models are all capable of delivering 1 kW of audio power. In high-impedance mode (70/100 V line), this maximum power can be intelligently shared between channels, allowing the amplifiers to drive different types or numbers of speakers.
in the different areas of a building or place with maximum economy.
Particular attention has been paid to the amplifiers' energy efficiency throughout their design. The Class D output stages eliminate the need for line output transformers, thus offering significant savings in weight and size compared to previous designs. A two-stage automatic power-off (APD) function results in a power consumption of less than 2.5 W. The amplifiers also include a remote standby/wake-up function, allowing them to be put into standby mode and subsequently switched on again by a simple external contact closure. The APD function can be disabled using a rear-panel DIP switch.
