[. . . ] INPUT PROCESSING MODULE FOR CKS, CKV & CKX SERIES POWER PROCESSING AMPLIFIERS Power Processing Modules NC-IPN Product Information Programmable Gain Input An internal jumper selects between gains of X20 (26 dB), X40 (32 dB), or constant sensitivity for full output at 0dBu (. 775V) in. [. . . ] In conjunction with NexSys® software, the hand-held N-Coder or N-Coder/PC software, the NC-IPN can also function as a precision attenuator in NexSys and non-NexSys controlled applications. Features: · NexSys-compatible gain control · Programmable precision attenuation via NexSys network, N-Coder or N-Coder/PC software. · Balanced input barrier strip connectors · Removable gain pot knobs for security · Input isolation transformers optional · Simple setup, tamper-proof configuration Internal Features: · Jumper-selectable gain of X20 (26 dB), X40 (32 dB, factory setting), or constant sensitivity for full output at 0dBu (. 775V) in.
