The MX20/6 has an additional PHANTOM switch for channels 9-16. Turn the switch ON when you are using condenser microphones, etc. When the switch is ON, +48V DC is supplied to pins 2 and 3 of the XLR type MIC INPUT connectors. If phantom power is not required, make sure the switch is set to the OFF position. NOTE: With this switch turned ON, it is not a problem to connect balanced dynamic microphones or line level devices however, hum or malfunction may occur when connecting unbalanced devices or devices for which the center of the transformer is ungrounded. e SEND Jack • 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. The jacks can be used to send the signal to a monitor system such as a cue-box. MX12/6, 20/6 — Owner’s Manual 8 Front & Rear Panels • EFFECT This is an impedance balanced phone type output jack with a nominal output/impedance of +4dB/ 600Ω. The EFFECT bus signal is sent from this jack. This jack is used to send the signal to an external effector, etc. r RETURN L (MONO), R Jacks These are unbalanced phone type line input jacks with a nominal input/impedance of +4dB/600Ω. The signal received by these jacks is sent to the STEREO bus, AUX1 and AUX2 buses. These jacks are normally used to receive a return signal from an external effector such as reverb, delay, etc., but they can also be used as an auxiliary stereo input. If only the L (MONO) jack is used, the same signal will be sent to both the R and L jacks for monaural input. t GROUP OUT (1-4) Jacks These are impedance balanced phone type output jacks that deliver the GROUP bus 1-4 signals, with a nominal output/impedance of +4dB/600Ω. These jacks are normally connected to the input jacks on an MTR or external mixer. y TAPE IN (L, R) Jacks These are line input jacks for monitoring an external DAT recorder or CD player. The signal received by these jacks is sent to the STEREO bus. In this case, the TAPE IN control is used to adjust the input level of the signal. You can also monitor directly from the C-R/ PHONES jack by making the appropriate selection with the C-R/PHONES Output and Meter Select Switch (Master Control Section). u REC OUT (L, R) Jacks With an external DAT recorder or cassette recorder connected to these jacks, you can record the same signal that is sent from the ST OUT jacks. The signal sent from these jacks is not affected by the ST Master Fader or Graphic EQ settings. Make recording level adjustments on the recording device. i POWER Switch When the switch is in the ON position, the unit is powered. When turning the power ON, first turn on the mixing console, then turn on the power amp or powered speakers that are connected to the mixer.
