Here is a picture of the NTP rack I set up for Bob Ludwig of Gateway Mastering.

The top piece is the PSU, the bottom piece is a pair of NTP 179-120 modules from his

Neumann mastering console. The middle piece is a Neumann RV75 input attenuator module.

It also houses a makeup gain circuit made with Burr-Brown driver's. The RV75 rack is the I/O for the

NTP compressor rack.
