5 AUX Controls (AUX1 to AUX6)
These knobs adjust the channels signal levels into AUX buses 1 to 6. Each knob controls the signal into the corresponding AUX bus. For AUX1 to AUX4, you use the PRE switch (6) to select whether the pre-fader or post-fader signal is fed to the bus. For AUX5 and AUX6, only the post-fader signal can be fed. These knobs should generally be set close to the position.

0 ON Switch

Sets the channel on or off. To turn the channel on, press the switch in ( ) so that it lights up orange. Be sure to turn on all the channels that you wish to use. If you set the channel off ( ), you cut off all of its signal feed into the ST, GROUP, AUX, and EFFECT buses.

NOTE The ON switch does not affect the operation of the PFL switch (A). You can monitor the channels pre-fader signal through the PHONES jack even when the ON switch is set off. To reduce noise, turn all unused channels off ( ).
On stereo channels, the L (odd) and R (even) input signals are mixed before moving into the AUX bus.
NOTE To enable use of AUX5 and AUX6, you must turn on the AUX5/AUX6 switch (8).
A PFL (Pre-Fader Listen) Switch
Use this switch to feed the channels pre-channel-fader signal into the PFL bus, so that you can monitor the signal from the PHONES jack. To turn PFL feed on, press the switch in ( ) so that it lights up.
NOTE If you switch on output to both the PFL and AFL buses, the mixer outputs only the PFL signal. If you set PFL on for multiple channels, the mixer feeds the mixed signal from the channels into the PFL bus.

6 PRE Switch

Selects whether the pre-fader or the post-fader signal is fed to the corresponding pair of AUX buses. The upper PRE switch controls the signal to AUX1 and AUX2; the lower switch controls the signal to AUX3 and AUX4. If the switch is on ( ), the mixer feeds the pre-fader signal to the corresponding buses. If off ( ), the mixer feeds the post-fader signal.
NOTE There is no PRE switch for AUX5 and AUX6. For these buses only the post-fader signal is available.
B PEAK indicator 7 EFFECT Controls
These knobs adjust the channels signal levels into EFFECT buses 1 and 2. Since the signal to the EFFECT buses is post-fader, the level is always determined by the combination of the EFFECT control and the channel fader. On stereo channels, the L (odd) and R (even) input signals are mixed before moving into the EFFECT bus.
NOTE These knobs operate as EFFECT controls only if the AUX5/AUX6 switch is in off position ( ). If the switch is on, these knobs adjust the output to the AUX5 and AUX6 buses. (See 8 below.)
Lights up when the channels post-equalizer signal level comes within 3 dB of the clipping level.

C SIGNAL indicator

Lights up when a signal is being input into the channel.

D GROUP Switches

Use these switches to feed the channels signal to the GROUP 1-2 and/or GROUP 3-4 buses. Setting the switch on ( ) causes the signal to feed into the corresponding GROUP buses.
NOTE These switches allow you to independently assign the signal to groups regardless of the setting of the ST switch (E).

8 AUX5, AUX6 Switch

Selects whether the channel signal is sent to AUX buses 5 and 6 or EFFECT buses l and 2. If the switch is on ( ), the signal goes to AUX5 and 6 buses; if off ( ), the signal goes to the EFFECT buses. Note that the signal to these buses is always post-fader.

E ST Switch

Set this switch on ( bus. ) to feed the channels signal to the ST

F Channel Fader

Adjusts the output level of the channels signal. Use these faders to adjust the volume balance among the various channels.
NOTE To reduce noise, set the fader sliders for unused channels all the way down.
9 PAN Control (Monaural Channels) BAL Control (Stereo Channels)
The PAN control adjusts the signals pan positioning into the Group 1-2 bus pair, into the Group 3-4 bus pair, and into the Stereo buss L and R lines. The BAL control knob sets the balance between left and right channels. Signals into the L input (odd channel) feed to the Group 1 and Group 3 buses and to the L line of the Stereo bus. Signals into the R input (even channel) feed to the Group 2 and Group 4 buses and to the R line of the Stereo bus.
NOTE If you are inputting to a stereo channel through the L (MONO) jack only, the BAL knob operates as a PAN knob.
MG32-14FX.fm Page 12 Thursday, December 11, 2003 10:30 AM

G PHANTOM +48 V Switch

Toggles phantom power on or off to a set of eight adjacent channels. The MG32/14FX has three of these switches: for CHs 1 to 8, for CHs 9 to 16, and for CHs 17 to 24. The MG24/14FX has two: for CHs 1 to 8 and for CHs 9 to16. If using condenser microphones, set the switch on ( ) for all channels to which these microphones are connected.
NOTE If this switch is on ( ), the mixer supplies DC +48 V power to pins 2 and 3 of all XLR-type jacks in the corresponding channels. Be sure to leave these switches off ( ) if you do not need phantom power. Humming or damage may result if you connect to an unbalanced device or to an ungrounded transformer while this switch is on ( ). But note that the switch may be left on without problem when connecting to balanced dynamic microphones. To avoid damage to speakers, be sure to turn off ampliers (or powered speakers) before turning these switches on or off.

I RETURN Section

This section adjusts the levels of the input from the RETURN 1 and RETURN 2 jacks (see page 20). For each RETURN, you can set independent levels for feeds into the ST bus and AUX buses 1 to 4.
1 AUX Mix Controls (1 to 4)
Each knob adjusts the level of the signal from the corresponding RETURN jack into the corresponding AUX bus (AUX1 to AUX4). If you are inputting a stereo signal, the L and R signals are mixed before moving to the AUX buses.

2 ST Control

Adjusts the level of the signal from the corresponding RETURN jack into the ST bus. If you are inputting a stereo signal, the L signal goes into the ST L line and the R signal goes into ST R line. If you are inputting a mono signal, the same signal is fed to both ST L and ST R.
3 PFL (Pre-Fader Listen) Switch
Use this switch to feed the corresponding RETURN signal, taken from before the ST and AUX Mix controls, into the PFL bus, so that you can monitor the signal at the PHONES jack. To turn the PFL feed on, press the switch in ( ).

I INTERNAL DIGITAL EFFECTS Section
You use this section to control the dual internal effects processor: to select the two effect types, to set the effects on or off, and to adjust the related signal levels and ows.
3 AUX PRE Controls (1 to 4)
Each knob adjusts the level of the effected sound into the corresponding AUX bus (AUX1 to AUX4).
4 TAP Button and Indicator
This feature lets you set the delay time for internal EFFECT 2 by tapping on the button. The feature only works if you have set the effect type for EFFECT 2 to [16] TAP DELAY. To set the delay time, tap on the button at the appropriate interval. The mixer measures the interval between the last two taps and sets this as the delay time. Continue tapping as necessary until you get the timing right.
The mixer retains the last time setting even after power goes off, and restores this setting the next time you set the effect type to TAP DELAY. The indicator next to the button ashes in sync with the delay time.

5 ON Switches

This switch turns the corresponding internal digital effect on ( ) or off ( ).
6 PFL (Pre-Fader Listen) Switches
Use this switch to feed the corresponding digital effect signal, taken from before the EFFECT RTN fader, into the PFL bus, so that you can monitor the signal from the PHONES jack. To turn the PFL feed on, press the switch in ( ).
NOTE The signal will not feed into the PFL bus if the effects ON switch (5) is turned off.

7 GROUP Switches

Set the switch on ( ) to feed the corresponding internal digital effect signal into the corresponding GROUP buses. The top button feeds the signal to Groups 1 and 2; the lower button feeds it to Groups 3 and 4.

8 ST Switches

Set this switch on to feed the corresponding internal digital effect signal into the ST bus.
9 EFFECT RTN faders (1, 2)
This fader adjusts the level of the effected sound into the ST and GROUP buses.

1 PROGRAM Dials

This dial sets the effect type for the corresponding internal digital effect. For information about the effect types, see page 24.

2 PARAMETER Controls

This knob sets the parameter value for the corresponding internal digital effect. The setting applies to the currently selected effect type.

NOTE The signal from these jacks is not adjusted by the ST master fader and is not affected by input or output at the INSERT I/O jacks. When using these jacks to record, adjust the level as necessary at the external recording device.

7 ST INSERT I/O (L, R) Jacks
These are balanced TRS (tip, ring, sleeve) phone-type bidirectional jacks. You use these jacks, for example, to connect to an external effector, submixer, or other such device.

9 ST OUT Jacks (L, R)

These are balanced XLR output jacks. These jacks output the mixed stereo signal from the mixers ST bus. The level for this output is adjusted by the ST master fader in the Master Control block (see page 13). You typically use the jacks to connect to your main output, such as to the power ampliers driving your main speakers.

0 MONO Jack

This balanced XLR input jack outputs a monaural mix of the stereo signal from the ST bus. The level for this output is controlled by the MONO fader in the Master Control block (see page 13). The output is a mix of the ST buss L and R signals.

A FOOT SWITCH TAP Jack

This phone input jack is for connection to a foot switch, for use with the TAP DELAY feature. If you connect the (separately sold) YAMAHA FC5 foot switch to this jack and then set internal EFFECT 2 to [16] TAP DELAY, you can use the foot switch (as an alternative to the TAP button) to set the delay. The mixer will automatically set the delay to the interval between the last two taps.
8 ST SUB OUT Jacks (L and R)
These are impedance-balanced phone output jacks. These jacks output a clone of the mixed stereo signal from the ST bus. The level for this output is adjusted by the ST SUB OUT control in the Master Control block (see page 13). You would typically use these jacks to connect to an external mixer or a supplementary SR system.

NOTE The ST master fader does not operate on the signals from these jacks.

B POWER Switch

Use this switch to turn the mixers power ON and OFF. Press the switch in to set the power on ( ), and press again to set the power off ( ).

C AC IN Connector

Connects to the socket end of the AC power cord included with the mixer.
