I’m trying to identify a continuous background noise from a Magnasync 60ch multichannel reel to reel reproducer.
It is mainly present on the voice playback channel, with a strong component around 1 kHz, and does not appear to be recorded on the tape itself. Rather stems from repdocuer or something
Could this be caused by the reproduce amplifier, power supply, grounding/shielding, or channel summing?
Has anyone heard a similar noise from Magnasync or other multichannel tape logging equipment?
