breaker trips instantly each time you attempt to reset it, the unit should be taken to a qualified service center for repair.

(6) OUTPUT MONITOR

This standard Quick-ConnectªRJ11 modular connector provides Channel A and B signals to PeaveyÕs booth monitor products such as the CA-M400. Refer to the diagram above the connector for proper polarity. (+ is equal to the channelÕs positive output.) The channels are indicated below the connector.

(7) BARRIER STRIP SPEAKER OUTPUTS

The SPEAKER OUTPUTS for each channel are provided by means of a heavy-duty, four screw barrier strip. The screw terminals marked Ò+Ó are the power amplifier outputs for each channel.

The remaining screw terminals are ground (chassis). The minimum recommended speaker load impedance is 4 ohms per channel, or 8 ohms in BRIDGE mode. Operation into loads below the recommended load impedance can result in temporary amplifier shutdown due to internal fault sensing.

(8) SPS SWITCH

This switch is used to either ENABLE or DEFEAT the SPS safety compressor. Normally, the SPS switch should be in the ENABLE position to minimize the possibility of a channel going into clipping or overload. With SPS defeated, a severe overload could cause the unitÕs circuit breaker to trip.

(9) MODE SWITCH

This switch is used to select either STEREO or BRIDGE mode for the amplifier operation. Care should be exercised whenever the BRIDGE mode is selected. Accidental selection of this mode could cause damage to loudspeakers, particularly in BIAMPED systems. NOTE: Peavey does not recommend the use of BRIDGE mode for normal theater applications.

(10) INPUT LEVEL

The INPUT controls are labeled in approximately 3 dB increments for ease of gain adjustment. Maximum input gain is achieved at the full clockwise setting. When used with CinemAcoustics signal processors, these controls should be left in the full clockwise position.

It features a Class D amplification system that not only enhances efficiency but also reduces heat generation, making it suitable for extended use without the risk of overheating.

On the other hand, the CA-A800B pushes the boundaries with 800 watts of power per channel at 4 ohms. This amplifier is designed to handle demanding environments, making it an excellent choice for larger venues or applications where additional headroom is required. The CA-A800B also utilizes advanced digital signal processing, enabling users to fine-tune their audio output for optimal performance.

Both models are equipped with a range of connectivity options, including XLR and 1/4" TRS inputs, ensuring compatibility with various sound systems. They also feature Speakon output connectors, providing a secure and efficient link to loudspeakers. The rear-panel controls allow for easy adjustment of gain levels, with peak LED indicators notifying users of any clipping.

Another significant characteristic of these amplifiers is their built-in protection systems. They include short-circuit, thermal, and overload protection, which safeguards the equipment from potential damage during high-intensity performances. This focus on durability ensures that users can depend on these amplifiers in any situation without worrying about unexpected failures.

In terms of physical design, the CA-A540B and CA-A800B boast a rugged yet lightweight construction, ideal for touring musicians and sound professionals. Their compact size allows for easy rack mounting, facilitating convenient transport and setup.

In conclusion, the Peavey CA-A540B and CA-A800B amplifiers offer outstanding power, versatility, and reliability, making them essential tools for anyone looking to achieve high-quality sound reinforcement. With their array of advanced features and robust design, these amplifiers stand out as premier choices in the competitive landscape of professional audio equipment.
