PPB10

The Palmer PPB10 is a specialized high-performance audio distribution amplifier designed specifically for press conferences, broadcast centers, and large-scale corporate events. It allows a single high-quality input signal (such as a feed from a mixing console) to be distributed to 10 independent, transformer-balanced outputs.

This ensures that every camera crew, radio journalist, and digital recorder receives a pristine, isolated signal without the risk of interference or signal loss between different media outlets.

Key Technical Features

• 10 Transformer-Balanced Outputs: Each output is electrically isolated using high-quality Palmer transformers. This prevents "hum" and buzz caused by ground loops between different connected devices (e.g., a TV camera and a portable recorder).

• Input Gain Control: A front-panel rotary control allows you to precisely adjust the incoming signal level to ensure optimal gain structure for all connected media.

• Individual Ground Lift: Every output channel features its own independent ground lift switch, providing surgical control over noise issues without affecting other journalists' feeds.

• Signal Monitoring: Includes a multi-segment LED ladder meter for visual monitoring of input levels and a headphone output with volume control for local signal checking.

• Expandable Design: Features a "Bus Out" link, allowing you to daisy-chain multiple PPB10 units together if you need to provide 20, 30, or more outputs for a major international media event.

Built for Critical Environments

• Professional 1U Rack Format: Housed in a standard 19-inch rack-mountable steel chassis, making it easy to integrate into a fly-rack or a permanent broadcast booth.

• Rugged Reliability: Like all Palmer gear, the PPB10 is built to survive the high-pressure environment of live news and touring.

• Internal Power Supply: Features a high-quality internal PSU (85V – 240V) with a standard IEC connector, eliminating the need for fragile external power bricks.
