HI Steve,
I think the product is made by Niles Audio.
The one I have has two rca phono jacks as outputs. I run these into the
tuner input of my Icom preamp.
It also has six inputs also fed by rca phono jacks.
It comes in a solid metal case and has a rugged rotary control in the center
of the front panel for selecting input sources.
I got mine for around $100 plus tax from a local California audio dealer.
Try doing a google search for Niles Audio and see what comes up.
Also, many high end hi-fi dealers carry Niles products.
I think they are used in home theatre applications.
Hope this helps.
