Schematic for Microphone Preamp

I couldn't find a web link for Pyramid Sound Corporation, but did find the address and contact info:

Pyramid Sound Corp.
1501 60th Street
Brooklyn, NY 11219
United States
718.436.1616 (Phone)
718.436.1401 (Fax)

Additionally I found a Pyramid Sound Productions and Pyramid Sound Studios, but I don't think you are looking for either of them.

The company website you are looking for is www.pyramidcaraudio.com. Their parent company is Lanzar. Apparently they deal in DJ equipment as well as car audio. They have manuals available online in pdf format, but no links to that information directly. (I found one with a Google search.) You will have to contact them to get the link to the manual you need, or order a hard copy.

Sorry, I posted my reply to your reply to "Schematic for Microphone Preamp", instead of that article directly.

Exactly I got the same:
You can ask sales@cbdistributing.com for their Vendor: Pyramid Sound Corporation for their contacts.
