User manual SOUNDCRAFT B400 BROCHURE

[. . . ] Production, on-air and OB faciliti R adio production, live, and outside broadcast each demand specific qualities in a mixing console, and addressing these disciplines in a single desk requires flexibility and uncompromised fidelity. The Soundcraft B400 takes these tasks in its stride while offering the additional benefits of inherent reliability, serviceability and Soundcraft's unique experience in the field of broadcasting. Based on the highly successful B800, the B400 delivers a level of configurability unrivalled in its class. Input frames can comprise any combination of Mono, Stereo and Stereo Telco modules. [. . . ] The Stereo Group offers greater packing density, and is more suited to applications where groups are treated as a stereo left-right pair. Stereo Return Stereo Return inputs via rear panel XLR sockets. Alternatively, by depressing the BUS switch the stereo return section will pick up signals from the 8 group output busses. (Feedback is avoided as no group can route to itself. ) PAN, LEVEL and MUTE controls are provided. The post mute stereo signal can be routed to the stereo mix and / or the group. The GROUP and BUS switches are interlocked such that the GROUP switch is over-ridden if both are depressed at the same time. The Stereo Return cue facility operates in the same manner as the cue facility on the input channels. Group Master The group insert can be switched in and out of the signal path, and an internal switch sets pre or postfade operation. Whether the insert is switched in or not, the group signal always appears at the insert send XLR. The group mute section, placed immediately before the fader, can be manually or remotely switched. An LED is provided to indicate remote mute activation. A remote control facility for machine start is available, via relay contacts which are closed when the fader is raised. The signal is sent to the group outputs (XLR on the mono, EDAC or stereo group). The signal is also passed to the PAN pot and then routed to the stereo bus. The stereo group is fitted with a BALance control, switchable to PAN, and an IMAGE WIDTH control. Feeds from the group to AUXes 1-4 are controlled by four pots. Each is switchable to pre or post fade operation. The group cue system operates as on the Mono and Stereo Input Modules. Two level indicator LEDs are provided: the SP LED illuminates when a signal is present on the group mix bus, and the PEAK LED illuminates whenever the output of the group mix amplifier or the postfader signal comes within 6dB of clipping. Stereo Master Module A fully featured Stereo Master Module is provided. Individual PSU status LEDs offer constant visual confirmation for the phantom, audio and logic voltage rails. The ON-AIR switch, operated manually or via an opto-isolator circuit, is used to close a set of relay contacts, for external signalisation; it also disables oscillator and some talkback facilities on the Communications Module. The aux master controls are located on this module.
