Description: For Sale: A used audio level control panel for testing and or mixing which is in decent physical condition. This is a passive 600 ohm attenuator/mixer control panel which was part of part of the Collins 478R-1 Spectrum Analyzer. It was originally used by Collins Radio test engineers to adjust or align SSB equipment using a two tone input (connected from external tone producing oscillators). The SSB signal was then analyzed on a Spectrum Analyzer for purity of emission. This control panel does not need to be confined to this original use. The mixing inputs are defined by what you inject into them. This panel could also be used to mix "tracks". Given a main track, two additional tracks could be switched in or switched out as needed. Use your experience & ingenuity to tailor it to your needs. The Daven pots are 600/600 I/O with 10 steps. There are two inputs for tone or signal input when desired and there are two filter positions with Z designators on the rear. We are including some specialty filters from a similar application so that you can design & build your own filters. We have no documentation on this but we do not think you will need that as the panel is passive and should work fine. Condition: Used, reuseable. No visible problems were found. Please study the pictures. The supplied plug-ins are provided for you to adapt or build to your own needs. Terms: Sold as described, as shown and strictly as is. This is not returnable. Shipping: We ship quickly.
