[. . . ] B2092A Users manual Version 1. 2 September 2006 TRUTH TRUTH B2092A IMPORTANT SAFETY INSTRUCTIONS 11) The apparatus shall be connected to a MAINS socket outlet with a protective earthing connection. 12) Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable. 14) Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). [. . . ] To avoid hum noise, your loudspeakers and your mixing console should all be connected to the same AC circuit. Connect your loudspeaker system to the Monitor/Control Room outputs of your mixing console. This way, you can adjust the listening volume independently from your mixing consoles main mix signal. Instead, you will need to use standard, commercially available two-core shielded XLR microphone cables. + Be sure to mute the signal sources before you power the B2092A on. There are different ways to integrate your B2092A into a loudspeaker system. Some examples are shown here: 3. 1. 1 Stereo setup with subwoofer + + Fig. APPLICATIONS TRUTH B2092A Connect the mixing console outputs to the B2092A inputs marked LEFT and RIGHT . B2030A or B2031A), connect the left loudspeaker to LEFT OUT, and connect the right loudspeaker to RIGHT OUT. If using passive loudspeakers, connect LEFT OUT and RIGHT OUT connectors to the power amplifier inputs. The B2092A separates the bass segment of the audio signal for the subwoofer and sends all frequencies above the 80-Hz mark to the outputs for the main loudspeakers. Surround system without decoder: You can create a surround system even without using a surround decoder, for example as a multichannel monitor system at your sound studio or for specific surround installations. The surround channels are reproduced using a single output of a mixing console, a surround monitor controller or using the separately recorded channels of a multitrack recorder. Connect the output of the front left channel to the LEFT IN connector on the B2092A; connect the output of the front right channel to the RIGHT IN connector. If the surround mix has no separate subwoofer channel, the signal for this channel is created using the bass segments of the left, center and right channels. Connect CENTER OUT to the center speaker and RIGHT OUT to the right speaker. All additional surround speakers (Left Surround = LS, Right Surround = RS) are connected directly to the corresponding outputs on your system. If you wish to use passive loudspeakers, connect the individual surround channels of your system to the power amp inputs of the corresponding surround speakers. 3. 1. 2 Multichannel surround setup 3. 2 Input signal level adjustment If the loudspeaker system is correctly wired and powered on, you can bring up the control room output of your mixing console or the volume controls of your decoder. If a signal source is connected, you can hear your B2092A for the first time. To obtain well-balanced sound, you only have to adjust the input sensitivity of your subwoofer. To adjust the signal level to the main speakers, values from -6 dB to +6 dB can be selected using this control. LIMIT LED lights up as soon as one of the internal overload circuits springs into action. By the way, no damage is caused to your B2092A if the LIMIT LED briefly lights up during operation (when signal peaks occur). However, you should try to avoid the LIMIT LED lighting up for prolonged periods of time (in that case, after a while the thermal fuse is activated, and the internal power amplifier is switched off for a while).
