AM-4U
Modular Power Amplifier
　
Features:
  • The AP-4U and the AM4-U 4 cannel modular system amplifiers are the most flexible solutions for any mobile and permanent installation application
  • The module slots on the front panel of AP-4U or AM-4U allow insertion of analogue or digital controller cards.
  • Therefore it is feasible to integrate the signal processing. Normally this is realized through external equipment. The advantage of handling things in this way is quite obvious.
  • Using the control modules provides the opportunity to set up very compact sound reinforcement systems, individually matching a particular application.
  • Cable length and connections are reduced to the minimal amount.
  • For example AP4-U can be attached to up to eight T18W, which forms a bass fundament for the TLA-101 Line Array or the Onax PA-Systems.
  • The mechanic construction and manufacturing guarantees highest sound precision. The robust and highly rigid steel chassis is meant to survive the extensive wear of touring applications.
