CA Series


The POPE Professional® CA-8150 is a 8-channel PA amplifier at compact size of 2U rack space. The front panel shows 8 gain controls for easy access, 8 mute-switches and the main switch. The LED informs about the condition of the amplifier. The rear side shows 8 input-connectors and 8 output-connectors. The input sensivity (gain) is 32 dB each channel. The outputs offer barrier strip connectors. The CA-8150 can be used also in half-bridged mode (4 x 400 watts RMS / 4 ohms). The CA-8150 can be switched into three different operation modes: stereo, parallel and bridge mode. The independent limiters can be switched on or off. All models are equipped with a switch-on delay to protect the connected speakers. The CA Series amplifier can drive 4-8 ohm or 70/100 volt loudspeakers.

Protection Systems

Clip Limiter: If the power amp is over driven and the limiter is set to on the clip detection triggers the Attack-Release-Circuit (ARC). The ARC delivers the control voltage for the gain reduction.

SOA Protection: Whenever the power transistors leave their Safe Operation Area (SOA), the SOA protection will either switch back the current rail of the respective channel or limit the maximum load current in the power transistors.

DC Protection: Each output of the power amp is constantly monitored for persistent DC voltage levels. If the 3 V thresholds are exceeded at any of the outputs, the corresponding channel will be muted. If DC was only applied for a short moment, the amplifier will release mute and work as normal. If DC is applied for longer periods or several short times the amplifier will switch to standby mode. Switch off the amplifier, wait until all indicator LEDs extinguish and switch the amplifier on again.

Over Current Protection: Over current is permanently controlled in the output stage. In case of excessive loading the maximum output current of the amplifiers is automatically limited. This improves reliability without degrading sound quality when driving complex loads. The main SMPS (Switched Mode Power Supply) transformer current of your M Series Amplifier is continuously monitored. If over current occurs the main SMPS immediately stops working. Should there be an internal failure this feature prevents other parts from being damaged.

Thermal Protection: There are sensors in each amplifier module in order to ascertain temperature data. If the temperature more than 85°C is detected at the heat sinks, the input signal on that channel is reduced proportionally to prevent further heating of the amplifier. If the temperature exceeds approximately 100 °C, the main SMPS is switched off (safety shut-off).

Mains Over Voltage Detection: Mains Over Voltage Detection is always operative. When the mains voltage exceeds approx. 268 V the amplifier will switch off. When the mains voltage returns to nominal value a soft start occurs.

Fuse Protection: The fuse protection circuit prevents amplifier shut-down (e.g. by a blown mains fuse or a triggered circuit breaker) during extremely hard use with all channels working at very high output power. Without intelligent mains current monitoring and control this could easily happen as the rated output power is several times higher than the capabilities of the standard mains supply. In order to prevent any shutdown in extreme situations the amplitude of the input signals will be reduced which will in return also reduce the mains current draw

Fans: The variable speed fans mounted in your M Series Amplifier operate permanently, but as long as the temperature remains below 40°C, they run at their slowest speed and can hardly be heard. The highest detected temperature from any amplifier channel controls the speed of the fans. Above 40°C the speed is increased until it reaches its maximum value.
