PRM Delta 28

A distribution amplifier is used to distribute a signal source to multiple outputs. The PRM-Delta 2.8 is a two-channel (stereo) distribution amplifier and can distribute two different sources to four outputs each. A mono switch, however, also makes it possible to mix two sources with one another and then distribute the sum signal to eight outputs. The PRM-Delta is designed to be extremely flexible. The unit is capable of processing all signals from microphone level up to a professional line level of +20 dBu. Besides toggling between microphone and line levels, the levels at both inputs and outputs can be adjusted individually and continuously using potentiometers. A level meter with 5 LEDs per channel provides a reliable means of visual monitoring.
When distributing signals, the devices are frequently located in different rooms and thus they are usually also powered by different power supply systems. This provokes ground loops and the annoying buzzing sound associated with them. This will not happen with a PRM-Delta 2.8; the line inputs and all outputs are balanced by high-quality transformers and thus galvanically isolated. Additionally, it is possible to isolate the case from the electronics ground.
