BLACK LION AUDIO PBR TT Patchbay
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 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.
-
Balanced TT connections:
Accepts TT (Bantam) jacks for connecting and routing your audio gear. Accepts balanced connections. -
Normal/Non-Normalled/Half-Normalled Switches:
Switch-es 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. 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.
SIGNAL FLOW IN YOUR TT PATCHBAY
The flow of signal through a patchbay module is affected by both physical
connections and mode setting (Normalled, Non-Normalled, 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.
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 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.
OPERATION
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.
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.
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.
This allows
you to use the patchbay as a molt (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.
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!
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.
