[. . . ] B2030A/B2031A Users Manual Version 1. 0 August 2003 TRUTH ENGLISH TRUTH B2030A/B2031A IMPORTANT SAFETY INSTRUCTIONS DETAILED SAFETY INSTRUCTIONS: 1) Read these instructions. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. 8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] 2. 6: Rear panel control elements The following control elements are found only on the B2031A: POWER MODE. This switch allows you to toggle between ON, OFF and AUTO power-up modes (see chapter 3. 1). When the TRUTH has been connected properly and switched on, you can now turn up the console output that feeds the B2030A/B2031A. 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 TRUTH automatically operates at maximum level, provided that your console has been set up correctly and its output is set to 0 dB. It lights up as soon as overloading causes one of the internal protections to respond. The TRUTH doesnt get damaged when the LIMIT LED lights up with occasional signal peaks. However, please make sure that it wont 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 TRUTH too hard. If so, you can reduce levels either on your console or using the INPUT TRIM control . If the outputs on your console dont 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 to the TRUTHs inputs, and use the CD player to adjust the volume. 6 3. APPLICATIONS + TRUTH B2030A/B2031A 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. 3. 3 Speaker placement suggestions Since the sound of a speaker depends to a great extent on its surroundings, placing your TRUTH correctly is very important. Your efforts will be rewarded with better sound and higher resolution. There is no need to concern yourself with which speaker should be placed left and which speaker should be placed right. 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 wont induce vibrations in nearby objects, which would affect the bass response. If you cannot use a stand, put the TRUTH on spikes or damping foam material. Another aspect is the distance between speaker and wall: keep the speaker away from the wall, as this would emphasize the bass response, particularly in corners, where two walls form an angle.
