Black Lion Audio PBR TRS Patchbay - 48-Point

The Black Lion Audio PBR TRS Patchbay uses 48 pairs of 1/4"" TRS (Tip-Ring-Sleeve) connectors, providing a total of 96 connection points.

In normal mode, the rear connection is automatically routed to the front. Plugging a cable into the front jack breaks this connection. In half-normal mode, the rear input is routed to the rear output. Plugging into the front input passes the signal through to the rear output without breaking the rear-to-rear connection. Plugging into the front output breaks the rear-to-rear connection.

While the patchbay has TRS connectors, it can accommodate unbalanced signals if your equipment outputs them. However, for optimal performance and to take advantage of balanced connections, using balanced TRS cables with compatible balanced gear is recommended.

The PBR TRS is a 48-point patchbay, meaning it has 48 channels. Since it uses TRS connectors, each channel can be utilized for stereo signals (two channels per point) or mono signals.

Yes, its durable construction and organized patching capabilities make it well-suited for both studio and live sound environments where quick and reliable signal routing is essential.

Specific dimensions are not provided in the product information, but it is designed to fit standard rack-mounting configurations typical for audio equipment.

Yes, the PBR TRS comes equipped with white labeling tags for each channel, allowing you to clearly mark your custom input and output assignments.

Verify that all cables are securely connected to both the external gear and the patchbay's front or rear jacks. Check the position of the normal/half-normal switches for the affected channels. Ensure the correct input and output settings are selected on your audio interface or console.

Ensure all connected equipment is properly grounded. Check for ground loops by temporarily disconnecting components. Use high-quality, shielded TRS cables. Confirm that the patchbay itself is not placed near sources of electromagnetic interference.

Inspect the TRS connectors on both the cables and the patchbay for damage or debris. Try swapping cables to rule out a faulty cable. Ensure the normal/half-normal switches are making solid contact.

Refer to the manual or the description of normal/half-normal modes and ensure the switches are set according to your desired signal flow. Double-check that you are using the correct front or rear jacks for your intended signal path.
