Patch Bay Tutorial
- 1). Connect a 1/4-inch cable to the electric guitar and leave the other end free. Connect a second 1/4-inch cable to the amplifier and leave the other end free.
- 2). Locate the four jacks that are designated as "1" on the patchbay. The four jacks are as follows: front A1, front B1, rear A1 and rear B1. Refer to the patchbay manual for the layout of the jacks. Connect the free end of the amplifier cable to rear A1.
- 3). Locate the patchbay switches for the jack combinations. These switches may be on top or on the front panel. Place the switch for location 1 in the "parallel" setting. If the patchbay doesn't have this setting, skip down to step five.
- 4). Place the amplifier on a low volume setting and turn it on. Keep the amplifier cable plugged into rear A1 and plug the free end of the guitar cable into front A1. Play the guitar to verify sound. Plug the guitar cable into front B1 and then rear B1, playing the guitar each time. Notice that there is sound in all connections. In the parallel setting, front A1, front B1, rear A1 and rear B1 are all connected.
- 5). Place the patchbay switch for location 1 in the "open" or "thru" setting. Keep the amplifier cable plugged into rear A1. Plug the guitar cable into front A1. Play the guitar to verify sound.
- 6). Plug the guitar cable into rear B1 and play the guitar. Notice that there is no sound. Plug the guitar cable into front B1 and play the guitar. Again, there will be no sound. Plug the amplifier cable into rear B1 and play the guitar. Notice that sound is restored. In the open/thru setting, front A1 is only connected to rear A1 and front B1 is only connected to rear B1.
- 7). Place the patchbay switch for location 1 on the "half-normal" or "half-normalled" setting. Plug the amplifier cable into rear A1 and the guitar cable into front A1. Play the guitar to verify sound.
- 8). Plug the guitar cable into rear B1 and play the guitar to verify sound. Plug one end of a third 1/4-inch cable into front A1 and leave the other end of the cable free. Play the guitar again to verify sound. Plug the guitar cable into front B1 and play the guitar. Notice that there is no sound.
- 9). Plug the amplifier cable into rear B1 and play the guitar. Notice that sound is restored. In the half-normal setting, front A1, rear A1 and rear B1 are all connected. When front B1 is used, it breaks that triple connection of front A1, rear A1 and rear B1. In that instance, front B1 only connects to rear B1 and front A1 only connects to rear A1.

Place the patchbay switch for location 1 on the "normal" or "normalled" setting. Plug the amplifier cable into rear A1, remove the third cable from front A1 and plug the guitar cable into front A1. Play the guitar to verify sound. - 11
Plug the guitar cable into rear B1 and play the guitar to verify sound. Plug the third cable into front A1 and play the guitar. Notice that there is no sound. Remove the third cable from front A1 and keep the guitar cable plugged into rear B1. Play the guitar and notice that sound is restored. - 12
Plug the guitar cable into front B1 and keep the amplifier cable plugged into rear A1. Play the guitar and notice that there is no sound. Plug the amplifier cable into rear B1 and play the guitar. Notice that sound is restored. In the normal setting, rear A1 and rear B1 are connected. Using either of the front jacks breaks that rear A1-B1 connection. When that occurs, front A1 is only connected to rear A1 and front B1 is only connected to rear B1.
