This is to make sure that your BX300 keeps working even when the going gets tough. 1. 1. 1 The DYNAMIZER technology When it comes to amplifying the signals delivered by electric instruments, youve got to separate the wheat from the chaff. Unlike mixed or mastered signals, electric instruments usually deliver extremely high signal peaks which, when raised in gain, produce nasty distortion. For your own safety, you should never remove any ground connectors from electrical devices or power cords or render them inoperative. You will find additional information in chapter 4 INSTALLATION. 1. 3 Control elements 1. 3. 1 Front panel Fig. 1. 1: Front panel control elements 1 2 3 4 5 6 7 8 These are the inputs for your electric bass guitar.
