When two MV802's are cascaded, one functions as a sub mixer and the second as a master mixer. The input channels on the sub-mixer operate normally but the master section controls are not used. The input channels of the master mixer also function normally, and its master section controls the entire system That is. the STEREO master level control. AUX SEND and AUX RETURN controls of the master mixer function for all 16 mput channels. VGA foot control applied to the master mixer also controls tUe overall output level of the entire program. The SUB IN/OUT switch determines whether the SUB I/O jacks function as inputs or outputs, and thus whether the MV802 functions as sub mixer or master mixer For sub mixer operation the SUB IN/OUT switch should be set to the "OUT" position, while for master mixer operation it should be set to the 'W position. The diagram below shows the pro per connections and switch settings. 9 STEREO OUT L & R jacksiconnectors The MV802 provides both unbalanced phone jack and balanced XLR connector outputs from the mam stereo buss. The signal delivered is a stereo mix of the input channel signals and the signals returned to the AUX RETURN jacks. The STEREO OUT signal will normally be used to drive a power amplifier and speaker system, powered keyboard speakers or a mam house mixing console. Nominal output level/ load impedance for the unbalanced phone jack out puts is + 4 o©/10 k-ohms Nominal output level/load impedance for the balanced XLR connectors is ♦ 4 dB/600 ohms. XLR and 1 4 inch phone plug outputs mav be used simultaneously, for example; the i;4 inch outputs would feed an on stage amplifier/ speaker system while the XLR outputs would send a stereo sub-mix to the house console. NOTE. The MV802 XLR connectors are wired ac cording to DIN specifications Pm 1 is shield (ground), pm 2 is hot (signal high) and pm 3 is cold (signal low) MV802 ISUBI MV802 (WASTER) NOTE: Refer to the BLOCK DIAGRAM on page 8 for details on signal routing in cascaded operation. NOTE: For normal single mixer operation the SUB IN/OUT sw»tch should be set to the "IN" position. In this condition the L. R. AUX 1 and AUX 2 SUB lacks function as inputs, and can be used to add external line level signals in to the corresponding stereo master and AUX busses. £ VCA CONTROL jack This jack accents pontroi voltage input from an op tionai Yamahc FC-7 f oot Controller. When the front panel VCA CONTROL switch is ON ar FC-7 con nected to this jack can be used for foot control of the signal level appearing at the STEREO OUT jacks. This allows convenient foot control of the overall volume of a group of keyboards, tone generators or other instruments while playing or performing other operations. Connection of sources with balanced outputs to the MV802 The MV802 keyboard mixer has unbalanced inputs using 1/4 mch phone jack connectors while the TX816 FM tone module rack for example, has balanced outputs and XLR type connectors Th*s apparent incompatibility can be easily and inexpensively overcome by usmg the audio cabte described below to connect the TX816 output to the MV802 mput The method outiined *s an ac cepted means of connectmg balanced and unbalanced equipment and is commonly used by aud
