The internal structure of bantam (top) and B-type (bottom) jack sockets.Ĭhoosing the most appropriate connector type for your installation is quite straightforward. As with all contacts in your signal path, the better the contact, the better the audio quality. A regular clean with a non-abrasive metal cleaner works wonders. The GPO connectors are often made of brass, which tarnishes quickly. One thing that definitely makes a difference to either type of connector is regular cleaning.

Due to their small size and resulting packing density, it is easy to skin your fingers when inserting bantam jacks, and I also feel that the larger contact material used in GPO types maintains a greater contact force over time, although I have not proven this. I personally dislike two aspects of bantam jacks. These are physically much smaller than the GPO type, but are constructed in exactly the same manner - as the saying goes, if it ain't broke.Īlthough the bantam jack is long established, a core of audio professionals (myself included) still prefer the older GPO connectors. This requirement gave birth to the bantam or TT ('tiny telephone') jack. In more recent years, as mixing consoles offered more and more inputs and outputs, the traditional GPO jacks started to consume too much panel space and a need arose for a smaller connector. A B-type jack inserted into an A-type socket will usually only result in a faulty connection, but an A-type jack can damage B-type sockets by stretching the internal contacts. Conversely, because the ring and tip of B-type connectors are smaller than those of domestic types, plugging a GPO jack into a domestic jack socket will usually result in only the sleeve connecting.Īlthough A-type (bottom) and B-type (top) jacks share the same sleeve dimensions, they are physically incompatible. This also reduces the switch contact pressure and causes intermittent normalling, more of which in a moment. The contacts become stretched and weak as a result. In addition to not forming a correct electrical connection, plugging a domestic jack into a GPO socket may well cause damage to the socket. It is important to note that, although a GPO jack has a similar quarter-inch sleeve diameter to the domestic (or A-type) jack found on instruments and guitar leads, the ring and tip are very different, and the two are physically incompatible. This type of connector is still used today in full-size professional audio jackfields and serves the same purpose as the telephone exchange: manually routing signals from one location to another. Variants of these original types later gained the additional designation of 'B type', 'GPO B' or 'BPO'. In the UK, the connectors were designed by the General Post Office and termed GPO jacks.

In those days, to place a telephone call, the user called the operator who then physically connected the call by means of patch cables in a jackfield.

Patchbays, also known as patchfields or jackfields, hail back to the bygone days of manual telephone exchanges. In this part, I would like to build on these concepts by covering the theoretical and practical aspects of patchbays. In my two previous studio installation articles (SOS September and November 2002), I've looked at soldering and wire preparation techniques, basic signal types and ground loops.

Plus, tips on building and fitting racks for your gear.
