AMPING mode PINS 1 1 and PINS 2 2 are looped througn 5 ADDITIONAL CONSIDERATIONS 5 1 Length and diameter of loudspeaker cables Loudspeaker cables whose diameter is too small can limit the power amp performance considerably The longer the cable the greater the problem As a result musicians often simply turn up the amp which can lead to loudspeaker damage Therefore don t use cables longer than 15 m 45 ft For most applications this will not be necessary Cable diameter should be at least 2 5 4 0 mm 5 2 Power amp rating Selecting the right amp can turn out to be rather difficult Therefore stick to the following rule of thumb the power rating of your amp should be roughly twice the speaker load capacity A speaker rated at 400 Watts continuous performance can easily be powered by an amp rated at 800 Watts output power An optimal addition to your speaker system would be the BEHRINGER EUROPOWER EP2500 power amp for example 5 3 Fuses We do not recommend the use of fuses with audio applications Damage to loudspeakers can be the result of high peak signals and high output power However fuses can only offer protection from one of these two factors and never from both Additionally fuse resistors are sometimes nonlinear leading to distortion and unpredictable overdriving 5 3 1 Protecting your equipment A Always try to find the optimal signal level Try to avoid overdriving your amp A Ke
