For sale:

One (1) mono channel Air Corp 500 PH Pro Announcer rack mount gear with rack handles.

I am selling this unit "for parts not working" because the power transformer has a slight acoustic hum. This is a hum from the actual unit, from the chassis. The hum is NOT in the audio signal. Overall this unit works and sounds great. The audio sounds great. All the features work. However the acoustic hum from the box is not suitable for all user situations. I placed the box inside a tight fitting rack and it masked the chassis hum fine. Or, if this was racked up in a control room away from microphones that would be ideal.

Has a few light scuffs on unit. All buttons and knobs are attached and work. Power cable included.

Please see pics.
