Audio PBR TT Patchbay
Product Information
The Black Lion Audio PBR-Series Patchbay is a versatile audio
equipment designed to facilitate signal flow management in your
setup. It allows you to easily route signals between different
audio devices, such as mixers, amplifiers, and processors.
The patchbay offers three modes of operation: Normalled,
Half-Normalled, and Nonnormalled. These modes determine how the
signal flows through the patchbay and can be adjusted to suit your
specific needs.
The most common configuration for the patchbay is for signals to
enter from the top rear connections and exit from the bottom rear
connections. On the front of the patchbay, the top row connections
are outputs, while the bottom row connections are inputs.
Signal Flow in Normalled Operation
In Normalled mode, when jacks are connected to the top rear and
bottom rear connections of a single module, signals coming into a
top rear connection are passed directly through to the output on
the bottom rear. This configuration reflects your hardware’s
default signal flow on a day-to-day basis.
Signal Flow in Half-Normalled Operation
In Half-Normalled mode, when jacks are connected to the top
rear, rear bottom, and front top jacks of a module, the signal is
passed through from the top rear to the top front without breaking
the connection. This allows you to use the patchbay as a splitter,
sending the signal to two different destinations. Inserting a cable
into the front bottom jack of a half-normalled module will break
the connection between the rear jacks.
Signal Flow in Non-Normalled Operation
In Non-Normalled mode, the top and bottom rows of jacks are not
connected. Modules set to non-normalled operation will pass the
signal straight through from front-to-back or back-to-front, but
not vertically. This mode is useful for setups where you want to
have full control over the routing of your devices without any
automatic connections.
Note: Running phantom power through the
patchbay is not advised, as it can cause damage to devices that are
not designed to handle it.
DB25 Wiring Convention
The PBR-Series Patchbay uses the Tascam DB25 wiring convention.
Ensure compatibility with your other DB25 hardware by checking
their documentation, as some audio equipment may use the Yamaha
convention.
Product Usage Instructions
- Connect your audio devices to the patchbay using appropriate
cables. - Choose the desired mode of operation: Normalled,
Half-Normalled, or Non-Normalled. - For Normalled operation, connect the top rear and bottom rear
jacks of a module to establish direct signal flow from input to
output. This is the default configuration for day-to-day
usage. - For Half-Normalled operation, connect the top rear, rear
bottom, and front top jacks of a module. This allows you to split
the signal and send it to two different destinations. Inserting a
cable into the front bottom jack will break the connection between
the rear jacks. - For Non-Normalled operation, no connections are made between
the top and bottom rows of jacks. This gives you full control over
the routing of your devices without any automatic connections. - Avoid running phantom power through the patchbay to prevent
potential damage to devices not designed to handle it.
Note: Refer to the documentation provided with
your audio devices and the patchbay for specific instructions on
connecting and configuring them.
SIGNAL FLOW IN YOUR TT PATCHBAY
The flow of signal through a patchbay module is affected by both physical connections and mode setting (Normalled, Nonnormalled, or Half-Normalled.) The most common configuration for a patchbay is for signals to come in to the patchbay from the top rear connections, and out of the patchbay from the bottom rear connections. Conversely, on the front of the patchbay, 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 patchbay 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.
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.
Fig. 5 This allows you to use the patchbay as a mult (splitter), sending the signal coming into the patchbay to two different destinations; very useful for parallel processing of your signal and monitoring applications. Inserting a cable in to the front bottom jack of a half-normalled module will break the connection between the rear jacks.
Fig. 1
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.
NON-NORMALLED OPERATION
AKA “open.” In non-normalled configuration, the top and bottom rows of jacks are not connected at all. Modules set to non-normalled 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 patchbay, as this makes it possible to send phantom power to a device not designed to handle it; expensive damage could result!

When all four jacks are connected to a patchbay module, a signal connected to a rear top input of the patchbay is passed to the front top output, while signal from the front bottom input is passed to the rear bottom output.

A Normalled configuration allows you to run several devices in series by using patch cables on the front of the patchbay 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.

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 HalfNormalled operation, switchable from the top of the unit on a per-module basis. A module, in this context, is any set of verticallyaligned jacks on the patchbay; TT on the front and DB25 on the back.
A typical patchbay 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 patchbay, and connect the delay’s Output to a DB25 Input connection, also on the rear.
