The microphone itself looks and sounds the same as the SPS422, but with special features in the Processor/Preamp. 5.13U TransAudio Group, Inc. - 7320 Smoke Ranch Rd Suite G Las Vegas, Nevada 89128 - Tel: 702-365-5155 Fax: 702-365-5145 We Accept: The TransAudio Group Network: BraunerUSA.com * DrawmerUSA.com * SoundFieldUSA.com * TransAudio Group * Las Vegas Pro Audio Site Design by Monomania Media
