Signal layer 1 (input) Contact pin gold plated insertion force 4.5 N Ghielmetti Connecting System Since many years already Ghielmetti products are used in radio and TV stations, sound studios, theatres as well as in data and signal networks. cut A Beryllium bronce ribbons Signal layer 2 (output) Hereafter the advantages of Ghielmetti Panels double contact system gold plated - High durability and reliability - No moving parts, wearless - Self cleaning at each insertion withdrawal operation Front view - Gold plated double contact system - Analog and digital application, AES/EBU st st 1 layer 2 layer - 3 pole signal lead, ground is activated - 2 pole switching, to prevent ground loops - Optional: High Performance with integrated channel shielding cut A - 2 years guarantee Coding hole for reverse polarity Functionality protection of the pach Basis of the Ghielmetti Systems are alloyed beryllium bronze cord ribbons, be nt and gold plated. These metal ribbons are inserted in patented plastic vats, 2 layers each compose together with front and rear plate a patch panel. cut B To each wire is dedicated a pair of contact ribbons. As shown in the drawing, these ribbons run in the 2nd layers vertically. The connection is made by contact pins, which are inserted in the front resp. rear side. Also the contact pins are gold plated. Because of the bending the ribbons are compressed outwards by Top view the contact pins. Thus ensures a absolutely safe and electrical clean connection. Due to the gold plating the surface is so Front panel Gold plated ribbons 1st layer smooth, that galvanic relevant humidity cannot affect the st plastic wat 1 layer contacting. Dust and other impureness are wiped away during the insertion withdrawal operation, the system is self cleaning. plastic wat 2 st layer Gold plated ribbons 2st layer rear panel Thanks to this functional principle the mentioned advantages result against the common jack fields actually available on the market. _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Audio @ Video @ Data Communications 1. Normal Patch Panel ASF -A Cut B For incoming and outgoing lines, which can be ranged on the Patch Cord patch panel by patching operations. Audio connection As shown on section drawing B, the contacts of the patchcord reach only the 1 st layer. On normal patch panels the 2 nd layer is Cut A not populated, and therefore inactive. Contact ribbon Cut B Front panel contact ribbon 1st layer 2st layer Cut A Cut B 2. Normal Patch Panel with parallel tap: ASF-AP Patch Cord Audio connection The functionality corresponds to the normal patch panel, though for incoming resp. outgoing signals 2 parallel connections are Cut A available for patch lines. Contact ribbon Cut B Front panel contact ribbon 1st layer 2st layer Cut A Cut B 3. Connecting Patch Panel ASF-AV Audio connection IN On the connecting patch panels incoming signals are on the top Cut A row, and outgoing signals on the buttom row. A connection Normalling plug between incoming and outgoing lines can be realised on 2 ways. As shown on the section drawing, the signal of the outgoing line is on the 2 nd layer. Audio connection OUT The input is on layer 1 same as with the normal patch panel. The Cut B direct connection between in- and output is made with a 3 pole normalling plug. The pins of the normalling plug are twice as long as those on the patchcord. This way 1 st layer is connected to 2 nd Front panel layer. contact ribbon 1st layer 2st layer Cut A Naturally the patching operations on the first layer are also Cut B possible as shown on the drawing.

Also customized devices can be easily realized. The basic elements exist of: Normal contact A Access to this contact are made by a patch cord. Two contacts in parallel A Access to this contacts are made by patch cords. P Connecting contact V Connection is made by a connecting plug. unplugged, the connection is separated. NOTE : The pins of the connecting plugs and the pins of the patch cord connectors have different lengths. Therefore there is no direct connection when the patch cord is inserted into the connecting contact. On the other hand, there is a direct connection between the incoming and outgoing line when a connecting plug is inserted.
