The Aphex Aural Exciter with Optical Big Bottom is a solid-state device that adds presence and warmth to one's voice (or music). While designed to be rack mounted, I used it on my desk top with a Heil PR781 and a Flex transceiver. It is now an extra (redundant) item that I have removed from my audio chain. Included are the Exciter, manual, power cable and Hosa (XLR3 - 1/4" TRS) interconnect cable. All are in excellent (i.e., mint) working and cosmetic condition. More pics available on request. Insured shipping (CONUS only) is included in the price of $150.00. E-mail: w2txb *at* yahoo *dot* com.
