New, economic and versatile designed 1/4" modular Patch Panel. 48 balanced channels in one rack space and just 1U high. Each of it’s 48 PCB wired balanced channels (24 front pairs and corresponding 24 rear pairs) can either be grounded separately or in groups of individually chooseable 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 loosing any small parts (e.g. nuts).
