Troubleshooting Congratulations and thank you for choosing the Knöll If a problem is encountered with the MVP44a, the most expedient MVP44a power amplifier. The MVP44a is designed to meet procedure is to locate the problem and if possible repair it before the amplifier needs of custom installed multi-zone systems requesting service. Be sure to carefully check other system where high quality sound is a specific requirement as well components such as controllers, CD players, volume controls, wirin

System layout considerations possible in the sequence to give the components settling time. For The MVP44a is the heart of a whole home music system. A MVP44a example, sequence a power-on command: CD on, tuner on, and CD is designed to work with 1-4 rooms or zones. Up to three MVP44a's play rather than CD on, CD play, and tuner ON. can be ganged together to allow up to 12 rooms or zones each individually controlling one or two pairs of enclosure or inwall 7.
