The NYS-SPP-L1 is a economical and remarkable sleek designed 1/4" modular Patch Panel for 19" rack mount (19"x 1U) with a reinforced metal housing. Each of its 48 PCB wired balanced channels (24 front pairs and corresponding 24 rear pairs) can either be grounded separately or in groups of individually choose able channel numbers.
The PCBs are held securely in place by being clamped between the front and the rear panel, this grants an easy reconfiguration of the Patch Panel without the danger of losing any small parts (e.g. nuts). The grey jack serves as an easy and distinguishable normalling identification.
