OVERVIEW The ART P48 48 Point Balanced Patch Bay is a deceptively simple, yet surprisingly useful addition to any serious collection of audio equipment. A patch bay organizes your cables and provides a convenient, easily accessible central location to make all of your audio connections. It also saves wear and tear on the connectors of your audio equipment because all connections are now made and changed at your patch bay.
USING A PATCH BAY Although the ART P48, like all patch bays, is conceptually a simple device, there is a lot in the terminology and usage conventions that can potentially cause confusion. Each vertical grouping of two jacks on the front of the unit and the corresponding two jacks and switch on the rear of the unit comprise a module and provides one channel of linked input/output audio connections.
With the rear panel pushbutton in the out position (Half Norm), the Half Normal mode is selected (refer to the Half Normal diagram below). This is the patch bay mode most commonly used. In this mode we can plug a cable into the top jack and take out or monitor the signal flowing through the rear jacks by sending it to an amplifier input or a set of headphones. This is shown in case B. However, if we plug a cable into the bottom jack, we break the connection between the rear jacks.
FREQUENTLY ASKED QUESTIONS Q: Can the P48 be used with unbalanced audio signals? A: Absolutely! Although the ART P48 uses three-conductor Tip/Ring/Sleeve (TRS) 1/4" phone jacks and maintains balanced connections internally, nothing prevents you from using twoconductor Tip/Sleeve (TS) phone plugs connected to unbalanced equipment.
