    Can you tell me the year my ATUS CP8506 Four Channel 48 Volt Phantom Power Supply was made? S/N 2374 Why was it discontinued? thank you MK

    Michael K

    The CP8506 was manufactured between 2004 and 2010. It was discontinued due to low sales. Unfortunately, we are no longer able to track serial numbers for this product, so a date of manufacture is not available. If you have any further questions, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Thanks!


    can the ATUS CP 8506 be used to provide phantom power to a radial active DI?


    This product is now discontinued but yes, provides 48v of phantom power to each output.


    Can the CP8506 phantom power supply be used in line between a mixer that has 15V. phantom power and microphones that require 48 V.


    Thank you for your inquiry. No, you should not do this unless you turn off phantom power to that channel.
