Overview

The DP-8 series cassette copier is a compact duplicating system for audio compact cassettes. The DP-8 series can duplicate cassettes at the copy rate of 16 times. The DP-8 series consists of two machines, the DP-8-C3 master unit and DP-8-Z4 copy unit. The DP-8-C3 includes one master deck and three copy decks, and a 1:3 duplication is obtained with a single use of the DP-8-C3. The DP-8-Z4 includes four copy decks and is used for only recording signals sent from the DP-8-C3. The duplication system can be easily expanded by connecting the DP-8-C3 with up to 15 DP-8-Z4s. A maximum system provides a 1:63 duplication system. Also, by combining the optional DP-10/DP-3 or DP-33 Digital Master Reproducer (x16) with the DP-8 series machines, the system provides high quality recordings.
