WONDOM CVA1_AMP 100W Power Amplifier Board Power Amp Board Audio Amplifier Module For Broadcast

Description:

CVA-1100 is a 100W constant power amplifier board consisting of a power unit and an amplifier unit, designed for distributed speaker systems like background music system, alarm system, broadcast system and so on. It can continuously output 70V/100V RMS directly with no need of an output transformer, which means you can connect the output directly to the distributed speakers with transformers. Besides the default constant voltage mode, CVA-1100 can function as a constant resistance amplifier board, driving an 8Ohm speaker for local audio playback. CVA-1100 features high reliability and stability, guaranteed by equipped full protection circuit, perfectly applicable to high demanding commercial and industrial applications.

Transformer-less 70V/100V RMS Output
CVA-1100 can directly continuously deliver 70V/100V RMS without need of an output transformer, highly reducing the weight and size, and improving frequency response and distortion which could be negatively influenced by the output transformer. You can connect CVA-1100 to the distributed speakers directly, greatly simplifying the installation and integration procedure.

Supporting Both Constant Voltage and Constant Resistance Mode
In addition to default constant voltage mode for mass notification system, CVA-1100 supports driving a low impedance speaker for local audio playback as well, improving the flexibility and expandability of the whole system. The switching of the two modes is extremely simple. We left a position on the CVA-1100 for switching. You only need to enable this position with a high level voltage.

Wide Power Supply Range as 90VAC-254VAC
CVA-1100 supports wide power supply range as 90VAC-254VAC. Therefore, it supports universal main power as 110VAC and 220VAC. High quality industrial terminals are installed on CVA-1100. You just need to connect power to CVA-1100 and wait for its start, no need for any other operations.

Two Levels Gain Adjustable
CVA-1100 provides two levels gain for your selection, high level gain as 37.7dB (80V/V) and low level gain as 32dB (40dB). There is a switch on CVA-1100 for the adjustment of gain level. The output voltage is determined by both input audio voltage and the gain.

Easy Control Functions
In order to help customers easily control the system, we equipped CVA-1100 with necessary control functions. We all know CVA-1100 is a power amplifier composed of a power unit and an amplifier board. The two units can be shutdown separately. CVA-1100 supports half power control, which means once the function is enabled, the output voltage of the power unit will decrease from ±72V to ±56V for lower power consumption.

External LEDs for Operating Status Monitoring
Ports for external LEDs are offer on CVA-1100 for better monitoring of the running condition of the system. LEDs are indicators for power, signal detection and protection mode. With these LEDs, you can have a better understanding of your CVA-1100 even if it’s integrated into a cabinet.

Full Protection for High Reliability
Bearing the strict requirements of distributed speaker system on reliability and stability in mind, we developed CVA-1100 with full protection circuit (OTP, OVP, UVP, DC Bias Protection) to ensure it can run stably for long time. In addition, all CVA-1100 need to pass through a series of rigorous tests like HASS and HALT test before storing in the warehouse. All the test data are recorded. Furthermore, if you have special requirements on tests, please contact us for further discussion.
