[. . . ] The MID sections have a bell response at a variable frequency. · · · The HF control gives 18dB of cut or boost switchable at frequencies 6kHz or 12kHz. Using the X3 switch multiplies the selected frequencies by three giving a selection of 120Hz or 240Hz. The HMF frequency control gives a variable frequency range of 80Hz to 5kHz. Using the X3 switch multiplies the selected frequencies by 3 giving a range of 240Hz to 15kHz. The EQ switch inserts the equaliser into the signal path. © Soundcraft Modules 5-5 Auxiliary Sends Note: The pre and post signals are the sum of the left and right signals except Aux 1 & 2 which has an internal switch option to configure it to a Stereo level/pan arrangement i. e. Aux 1 will be fed by the left only and Aux 2 will be fed from the right only. All the Auxs have unity gain when the controls are fully clockwise and are switched pre or post in pairs by the PRE switches. Routing 9. Panning left pans to the odd groups and Stereo left, panning right pans to the even groups and Stereo right. The Stereo Mute switch cuts off all output from the channel and utilises a soft mute for click free switching. The PFL switch provides a pre fade signal to the monitor speakers replacing the selected source. There is an internal switched option, which allows the PFL to become a post fade signal - this signal is a derived post pan. Groups are available only if the appropriate amount of group modules are fitted. The meter monitors the signal pre mute, left and right simultaneously. The O/L led illuminates when the signal reaches +18dB. 5-6 Modules © Soundcraft LB2 Dual Group Module The Dual Group Module is provided with XLRs on a 4 group console and ¼ jacks on a 8 group console, insert send and returns. Clean feed outputs are provided on XLRs on an 8 group console and jacks on a 4 group console. The other four Auxiliaries are fed from the other group (Right) fader. Each Dual Group module contains one clean-feed master therefore the amount of clean-feed buses is dependent on the amount of Dual Group modules fitted. The Level control adjusts the level of the balanced Clean-Feed output which is fed from the selected clean-feed input module. Jumpers make the clean-feed bus selection of which positions are used to source on the 14 position motherboard. Therefore if the signal is inserted into the first of the input modules (clean-feed 1) it will then be removed from the clean-feed output 1 on the group module. The Talk Enable switch provides signal from the Comms system to be fed to the clean-feed outputs when the Comms system is activated. The clean-feed Mute switch cuts off the signal to the clean-feed outputs. [. . . ] 8-3 8-2 Specifications © Soundcraft Technical Specification Console Types All specifications for the BB100 console apply to consoles that are installed completely in accordance with Soundcraft's recommendations. The figures in this specification are typical figures measured on a console, immediately after completing normal production tests. Figures will therefore vary slightly from console to console and the results here should not be regarded as `guaranteed minimum performance'. They should be taken only as indicative of the results that might be obtained. Noise Microphone equivalent input noise Measured at the channel insert point, 22Hz ­ 22kHz band, RMS. [. . . ]
