BLACK LION Audio PBR TT Patchbay
SIGNAL FLOW IN YOUR TT PATCHBAY
-
The flow of signal through a patch bay module is affected by both physical connections and mode settings (Normalled, Non-normally, or Half-Normalled.) The most common configuration for a patch bay is for signals to come into the patchbay from the top rear connections, and out of the patch bay from the bottom rear connections. Conversely, on the front of the patch bay, the top row connections are outputs and the bottom row connections are inputs.
-
With jacks connected to the top rear and bottom rear of a single patch bay module, signals coming into a top rear connection are passed directly through to the output on the bottom rear, as shown here. This connection style should be used for your hardware’s “default” configuration – the way you want your signals to flow on a day-to-day basis.
-
When no jacks are connected to the top connections of a module, a signal from the front bottom input is passed through to the rear bottom output.
-
When all four jacks are connected to a patch bay module, a signal connected to the rear top input of the patch bay is passed to the front top output, while a signal from the front bottom input is passed to the rear bottom output.
NORMALLED OPERATION
- When a module is set to Normalled and connections are made to the top rear and top front jacks, the signal is passed through from the top rear to the top front – breaking the connection shown in figure 1.
NORMAL MODE
- A normal configuration allows you to run several devices in series by using patch cables on the front of the patch bay to interconnect several of your devices. For example, you could run a signal from a preamp, to a compressor, and finally to a reverb. A cable inserted into the bottom rear will have its connection broken when a cable is inserted into the top front.
HALF-NORMALLED OPERATION
- When a module is set to Half-Normalled and connections are made to the rear top, rear bottom, and front top jacks, the signal is passed through from the top rear to the top front – without breaking the connection shown in Figure 1.
HALF-NORMALLED MODE
- This allows you to use the patch bay as a mult (splitter), sending the signal coming into the patch bay to two different destinations; very useful for parallel processing of your signal and monitoring applications. Inserting a cable into the front bottom jack of a half-normalled module will break the connection between the rear jacks.
NON-NORMALLED OPERATION
- AKA “open.” In a non-normalled configuration, the top and bottom rows of jacks are not connected at all. Modules set to non-normally operation will pass signal straight through from front-to-back or back-to-front, but not vertically. Useful for setups where you do not want your devices to automatically route anywhere.
ON PHANTOM POWER
- We advise against running phantom power through your patch bay, as this makes it possible to send phantom power to a device not designed to handle it; expensive damage could result!
DB25 WIRING CONVENTION
- The PBR TT Patchbay uses the Tascam DB25 wiring convention. Some audio equipment uses the Yamaha convention. Check the documentation for your other DB25 hardware to ensure compatibility.

CONNECTIONS
- The PBR TT offers 96 points of connectivity for your studio gear, allowing for permanent installation and routing of your favorite hardware while still allowing for flexible and creative patching.
- The PBR TT Patchbay offers Normalled, Non-Normalled, and Half-Normalled operation, switchable from the top of the unit on a per-module basis. A module, in this context, is any set of vertically-aligned jacks on the patchbay; TT on the front and DB25 on the back.
- A typical patch bay configuration will have device outputs sent to the top rear row of patch points with device Inputs connected to the rear bottom row. For example, you would connect the Input of a delay unit or compressor to a DB25 output connection on the rear of the patch bay, and connect the delay’s Output to a DB25 Input connection, also on the rear.
- Balanced TT connections: Accepts TT (Bantam) jacks for connecting and routing your audio gear. Accepts balanced connections.
- Normal/Non-Normalled/Half-Normalled Switches: Switches the routing for its respective module between Normal, Non-Normal, and Half Normalled operation. Switch up = Half-Normal, Switch mid = Non-normal. Switch down = Normal
- DB25 connections. Accepts DB25 connections (eight channels in a breakout cable) for connecting to the inputs and outputs of your outboard equipment. A common convention is to connect the top row of connections to device outputs and the bottom row to device inputs.
- Grounding lug. Connect this to your outboard equipment using a ground wire to prevent noise from ground loops.
