No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure ­ voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] The benefits mentioned above will apply only when both inputs and outputs are of the balanced type. If all else fails, you can still connect the TRUTH to the headphones output of your console. Be sure to mute the signal sources before you put the B2031 into operation. Once the TRUTH has been connected as described above, you can activate the speaker with switch . 2. 2 Level setting When the TRUTH has been connected properly and switched on, you can now turn up the console output that feeds the B2031. Provided you have a signal source connected, you now hear the audio material as it is played back by the TRUTH. The INPUT TRIM control on the rear panel is set to 0 dB ex-factory, i. e. unity gain, which is okay when you feed the TRUTH from a pro-level console. In this case, the B2031 automatically operates at maximum level, provided that your console has been set up correctly and its output is set to 0 dB. The LIMIT LED helps you control the level. It lights up as soon as overloading causes one of the internal protections to respond. The TRUTH doesn't get damaged when the LIMIT LED lights up with occasional signal peaks. However, please make sure that it won't light up all the time, because sooner or later this will activate the thermal protection system and temporarily mute the built-in amplifiers, to warn you that you are driving the . If so, you can reduce levels either on your console or using the INPUT TRIM control If the outputs on your console don't provide studio-level signals, you can turn up the INPUT TRIM control. If you connect the TRUTH to the preamp output of your stereo system, it may also be necessary to raise the level on the TRUTH itself. To build up a rudimentary stereo system, you can directly connect the outputs of a CD player (if they can be controlled in volume) to the B2031's inputs, and use the CD player to adjust the volume. The TRUTH is capable of producing high volume levels. You should mix your recordings at moderate levels, so as to avoid listening fatigue and hearing impairment. 2. APPLICATIONS 9 TRUTH B2031 2. 3 Recommended setup Even though the B2031 is an excellent active speaker, it needs to be set up with great care, because even the built-in room adaptation facility cannot make up for poor positioning of the speaker. Please try to heed the following suggestions. As the TRUTH will give you an even better sound and higher resolution, it will be worth the trouble. Place the TRUTH on a flat and stable surface, if possible use a dedicated speaker stand. In this way, the speaker is acoustically decoupled and won't induce vibrations in nearby objects, which would affect the bass response.
