2 MV12/6 Features Contents • The MV12/6 offers 12 input channels that can be mixed into stereo, monaural, or to four group outputs. Front & Rear Panels ............................ 3 • A MONITOR jack offers easy connection to a sub amp for monitoring. It allows monitoring of the main stereo output, TAPE IN input and the signals from groups 1-2, 3-4. Channel Control Section ........................ 3 • The mixer is equipped with a highly efficient, built-in digital effects section.
Front & Rear Panels 3 Front & Rear Panels Channel Control Section Channels 1-8 (Monaural) q GAIN Control Channels 9-12 (Stereo) Adjusts the input level of the signal entering the mixer to an optimum level. To obtain an optimum balance between the S/N ratio and dynamic range, adjust the level so that the PEAK Indicator w occasionally lights. -60 to -16 indicates the MIC input adjustment level, -34 to +10 indicates the LINE input adjustment level.
4 Front & Rear Panels y EFFECT Control Controls the level of the signal sent from each channel to the EFFECT bus. This control is located after the channel fader so its level will also be affected by the channel fader setting. When a stereo channel is used, L and R channel signals are combined and sent to the EFFECT bus.
Front & Rear Panels 5 Master Control Section q ST Master Fader !4 !1 Controls the level of the signal that is sent to the ST OUT jacks. !2 !5 w MONO Control Controls the level of the signal (the monaural signal that is formed by combining the signals from the STEREO bus) that is sent to the MONO OUT jack. e GROUP 1-4 Faders r TO ST Switch !3 o y !0 t u i w Controls the level of the GROUP 1-4 signals, and sends the signals to their respective GROUP OUTPUT 1-4 jacks.

8 Front & Rear Panels t SEND Jacks • AUX1, AUX2 These are impedance balanced phone type output jacks with a nominal output/impedance of +4dB/ 600Ω. The AUX1, 2 bus signals are output from their respective jacks. These jacks can be used to send the signal to monitor system such as a cue-box. • EFFECT This is an impedance balanced phone type output jack with a nominal output/impedance of +4dB/ 600Ω. The signal from the EFFECT bus is output from this jack.
Front & Rear Panels 9 !1 MONO OUT Jack This signal is the monaural mix of the STEREO bus’s stereo signal. Its level is controlled with the MONO control. Two types of jacks are provided; balanced XLR type and Euro-block connectors. • XLR type (1: Ground, 2: Hot, 3: Cold) Nominal output/impedance +4dB/600Ω • Euro-block connector ( : Hot, : Cold, G: Ground) Nominal output/impedance +4dB/600Ω !2 MONITOR (L, R) Jacks This is an unbalanced Euro-block connector output jack for connecting a monitor system, etc.
10 Front & Rear Panels ■ Changing the connector panel’s location. The mixer allows attachment of the connector panel to either the rear or to the top-side of the mixer to provide optimum location of the connectors when installing the unit.
