Anyone know what this unit was used for?
It appears to have 4 speaker amps, each with its own level
control, and one amp that may be a transmitter audio line
driver. Provisions for powering or selecting 4 transmitters
with a place to plug in a mike and key.
Being Navy gray, looks like it would feel right at home
in a rack with some R-390s.
Thanks
