Analog mixing consoles and other studio and public-address equipment need regular maintenance and minor repairs to be in tip-top condition. It is not good for productivity if some channels of the mixer are noisy or show intermittent issues. We have maintained our own equipment in our Studio 1 and Studio 2 as well as our present post-production facility. We have also helped a few other studios with maintenance work.
