[. . . ] B2030P/B2031P Users Manual Version 1. 0 August 2003 TRUTH ENGLISH TRUTH B2030P/B2031P IMPORTANT SAFETY INSTRUCTIONS 1) Read these instructions. 7) Be sure to mount your speakers on a solid, stable and level base or stand. Vibrating floors do not provide reliable support for speaker enclosures or stacks. 8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] Now insert the plus cord of the speaker cable connecting the amp to your TRUTH into the plus opening. Then, connect the minus cable into the minus opening. Do the same to connect the other TRUTH. + Make sure that all connections are done properly. Speaker cables are color-coded to help avoid confusion. Youll know that the signal is inverted (i. e. youve mixed up the connections) when you notice that bass frequencies are getting lost and when the stereo characteristic of the signal is majorly worse. Always make sure that bare wire ends never touch the open end of another speaker cable, speaker connectors or metal parts of your amp. + Fig. APPLICATION 5 TRUTH B2030P/B2031P 3. 1. 1 The truth about speaker cables Carefully approach the choice of what cables you use. Which cables you use can have a major influence on your sound. Cables of various lengths and diameters affect the resistance valuecausing a loss in power. On the other hand, that doesnt mean that you should be buying high-end cables that cost as much as your speakers. Simply use the following rule of thumb: Whenever possible, use cables with large diameters (gauge) and keep the cable length to a minimum. The screw clamps on your TRUTH can accept cable thickness of up to 7 mm² (9 AWG). The BEHRINGER TRUTH B2030P/B2031P is a so-called nearfield monitor, which means that the impact of the room acoustics on the sound will be reduced considerably owing to the short distance between speaker and listener. 3. 1. 2 Amp The power rating of the amp you use should be roughly twice the load capacity of your TRUTH. Consequently, the B2030P should be operated with an amp with a load capacity of 2 x 200 Watts, and the B2031P with an amp with a load capacity of 2 x 300 Watts. Also, you should keep in mind the impedance of your TRUTH in order to guarantee optimal power delivery. The B2031Ps impedance is 4 , whereas the B2030Ps is 8 . Use an amp whose power rating roughly corresponds to the values recommended in the table. The impedance should correspond to the values listed in the table: Fig. 3. 2: Incorrect speaker setup This illustration shows how you shouldnt do it: you can clearly see that a portion of the sound bounces back from the walls before it reaches the listeners ears. Thus, direct and reflected sound waves overlap which results in a coloration of the sound.
