[. . . ] directly onto the PC and played back via the 2-track input of the mixer (playback/monitoring), without a single patch cable having to be plugged in!In this way, you can build up a basic configuration for your studio, which can be easily modified by simply patching signals via the front-panel jacks (pos. ) or by feeding in external signals via patch cables (pos. You could, for example, connect the keyboard signal to channels 3 and 4 by patching 1A to 3B, and 2A to 4B. [. . . ] This configuration also allows you to position the inputs and outputs of effects devices, compressors, equalizers, etc. In the example configuration above, the outputs of the playback devices (CD and mini-disc) plus the four individual outputs of a sampler are connected to channels 17 to 20, while channels 21 to 24 are used for the inputs & outputs of a compressor and an EQ, which are usually connected to the inserts of a mixer. Fig. WIRING & GROUNDING Looming the wiring is an art itself and it is worth the time to get it right. First, it is important to avoid ground loops. Dont remove the ground connection of your mains cable plug to reduce 50/60 Hz mains hum. Instead, systematically disconnect the signal shields in the signal chain until the hum ceases. It is typically best to connect only one end of each shield to a central point and to connect this single point to ground. Then all equipment will be grounded via a single path (more than one path can lead to ground loops which can cause hum). Some equipment has isolated grounding for the signals and the mains. In this case, at least one screen should ground the equipment. Please assure that the patchbay is installed so that it does not disturb the studios grounding scheme. Always use patch leads that are as short as possible and have the shield connected at both ends. After eliminating the mains hum from the system, make your cable looms from the patchbays outwards and use cable ties, flexible sheaths, multicores, etc. It is also wise to keep low level/line level signal cables away from high voltage/mains cables. SPECIFICATIONS Connectors Dimensions (H x W x D) Weight 1/4" TRS, balanced approx. 1 3/4" x 19" x 3 2/3" (44. 5 mm x 482. 6 mm x 93 mm) approx. CAUTIONS Avoid routing digital signals near a patchbay because the pulse signal used for the transmission of digital signals causes heavy interference in analog signals. Do not use standard patchbays for digital signals. Use the ULTRAMATCH PRO SRC2496it is specifically designed for routing and matching digital signals. Microphone inputs are for very low level signals and should never be routed via a patchbay. Plus, the +48 Volt phantom power from the mic input could damage other equipment. It is best to plug mics directly into the mixer or via a wall box using good quality balanced multi-core cables. BEHRINGER is constantly striving to maintain the highest professional standards.
