Lectrosonics PA8 8 Channel Power Amplifier

Introducing the Lectrosonics PA8 Power Amplifier The Lectrosonics PA8 is an innovative 8-channel power amplifier, uniquely designed to fit into a single rack-space, making it the perfect solution for zoned, distributed loudspeaker systems. Each channel offers a robust output of 10W at 4 Ohms or 6W at 8 Ohms, catering to diverse audio needs. This amplifier is ideally suited for applications requiring multiple, independent zones of sound without the clutter of multiple equipment pieces.

Efficient Design and Cooling The PA8 stands out with its passive cooling system, eliminating the need for fans and reducing noise that could interfere with audio output. Its efficient design also includes full short-circuit and thermal overload protection, ensuring reliable performance and durability. The amplifier outputs are muted during turn-on and turn-off to prevent any unwanted transients, enhancing the overall audio experience and equipment safety.

Advanced Transformer Technology At the core of the PA8's power supply is a low radiation toroidal transformer, which is crucial for reducing heat and minimizing electromagnetic interference. This feature is particularly beneficial when the amplifier is used near sensitive microphone pre-amplifiers, as it ensures clean, uninterrupted audio performance with significantly reduced 60Hz energy emission.

Reliable and Robust Amplification Each of the eight channels in the PA8 operates with a straightforward, low-parts-count design which enhances long-term reliability. These channels are designed to handle challenging audio environments, being internally power limited to protect against short circuits, low impedances, or reactive loads. Additionally, the thermal limiting features intelligently shut down the unit under extreme conditions to avoid thermal shock.

Flexible Configuration Options The PA8 offers versatile configuration possibilities, including bridged mode which allows any two channels to combine for higher output power—20W at 8 Ohms or 12W at 16 Ohms. This flexibility makes it suitable for various installation scenarios, from small venues to large, complex audio setups.
