The ADC PPA3-14MKIINS is a durable, professional audio patch bay built to manage complex audio signal flow in studios, broadcast facilities, and post-production houses. It features 48 jack positions in a 24x2 configuration, utilizing the robust and industry-standard 1/4-inch longframe jacks known for their reliability and longevity. The panel is designed for solderless installation, using easy-to-terminate E3 or "punch-down" connectors on the rear, simplifying the wiring process. A key feature is the user-adjustable normalling, accessible via switches on the front panel. This allows technicians to quickly configure the signal flow between the top and bottom rows (full normal, half normal, or non-normal/open) to suit specific system requirements without re-wiring. The panel occupies a single rack unit (1U) of space, making it an efficient solution for high-density audio patching.
