For sale by former studio owner: DBX excellent technology for noise reduction of analog recording. rnrnEncodes and decodes analog audio signal better than dolby. Also decodes discs specially recorded with DBX.

Now no dynamic range (even digital) is too wide for your analog recorder. No other noise reduction system can do this as well. If you do analog recording, you will love this.rnrnPerfect working order, original owner, with instruction manual.rnrn$20 for one, both for $35. Together, they are great for 4-track tape recording.rnrnPay by PayPal, USPS money order, or cash.
