This is an audio-technica catalog specifically for music production. - Brand: audio-technica - Title: For Music Players Thank you for viewing. I believe this is from around 2002 or 2003. The first two pages feature artists who use the products (photos 3 and 4). The catalog is about 35 pages long. It includes condenser microphones such as: AT4060, AT4050, AT4047, AT4040, AT4035 as well as dynamic microphones, wireless systems, headphones, and more. There are punch holes, likely from the bottom. It's in good condition, but please understand that it is old.
