4. impair the performance of your system Just to avoid any confusion a speaker that has a low impedance has a greater load on the amplifier So a maximum load refers to a minimum speaker impedance as more current 1s flowing through the amplifier s output stage speaker cables and cabinets OPERATION amp POSITIONING TURN THE VOLUME DOWN on the D 600 before plugging in your instrument Connect the speaker or speakers to the D 600 For best results with this amplifier you should use PJB loudspeaker cabinets and PJB cables ALWAYS USE A HIGH QUALITY GROUNDED AC POWER CABLE NEVER USE THIS AMPLIFIER WITH THE GROUND CONNECTION REMOVED We recommend you use PJB cables for speaker connections as they have virtually no loss so there is maximum transfer of power from amplifier to speaker Setting Up the Limiter Although a limiter is not essential to bass amplification it can be a useful tool in smoothing out the character of your instrument or playing style The D 600 limiter has a preset compression ratio of 3 to 1 For each additional increase of 3dB above the set threshold the increase in level is actually 1dB So the dynamic range of your instrument is reduced First set up the limiter by having the compression control 10 set fully clockwise Now switch on the limiter 23 Start playing and turn control 10 counter clockwise You will see the blue light start to come on and that is the indication that the limiter is now working Set this con
