DBX Expander


I have recently acquired a Teac reel to reel and although it's a great machine, soundwise, it just doesn't measure up to CD or LP's in my system. I have a chance to purchase a DBX sound expander that I'm told greatly enhances the sound of the tape. I have no experience with this box at all. Does anyone have any knowledge of what this does?

I agree as well. The DBX does to much pumping of the signal.
Although the ONE BAND DBX seemed to not do as much pumping as the others. Teac use to make an outboard noice reduction device for their machines as well which may have lowered the noise another 5 or 6 db without the pumping affects. If your a tweaker, you can try replacing the resistors and or the caps in the recording board, which is what I did to my Teac and had noticed a definate improvement in lower noise.But this is very time consuming indeed.
