Provides 24 (MG32/14FX) or 16 (MG24/14FX) monaural input channels suitable for connection to both microphones and line-level devices. Also provides four line-level stereo inputs. Built-in dual digital effector, based on Yamahas acclaimed SPX multi-effector technology, can apply a variety of internal effects to both vocal and instrumental inputs. Convenient tap delay feature lets you set the internal effects delay time by tapping on a button (or by stepping on a separately-sold foot switch). Provides dual stereo outputs, two effect outputs, six AUX outputs, and four group outputsfor a total of 14 outputs. You can use the AUX and GROUP outputs both to connect to external devices (such as effectors and MTRs) and to create custom mixes for targeted speakers or amps for stage monitoring. An independently controlled MONO output jack feeds out a mix of the main ST output signal, ideal for connection to a subwoofer or other SR system extension. All monaural channels are equipped with an INSERT I/O jack for independent connection to an external effector. Includes independent PFL switches for each input channel, for each AUX return, and for the 2TR IN bus, together with independent AFL switches for each AUX and GROUP output and for the main ST output. These switches make it easy to selectively monitor the input and output signals through headphones connected to the PHONES jack. Phantom power supply can provide DC +48 power to all XLR input jacks, allowing you to connect phantom-powered condenser mics and direct boxes to any combination of monaural channels. The phantom power can be independently switched on and off in eight-channel blocks. Dual RETURN jacks can feed AUX return signals not only into the ST bus but also into four of the AUX buses. These jacks can also serve as an auxiliary stereo input.

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 mixer saves the last value used with each effect type. When you change to a different effect type, the mixer automatically restores the value that was previously used with the newly selected effect (regardless of the current position of the Parameter Control knob). These parameter values are retained even after power-off.

I METER/PHONES Section

You use these meters to view various signal levels: the levels to the ST OUT jacks, the PFL and AFL levels, and the levels to the GROUP OUT jacks. The PFL or AFL signals indicated by these meters can be monitored through the PHONES jack.

5 PHONES Jack and Control
PHONES Jack An unbalanced stereo phone output jack, for connection to headphones. PHONES Control Controls the level of the signal output to the PHONES jack for monitoring.
NOTE The PFL-AFL level meter (3) shows the level of the signal monitored through the PHONES jack.

I 2TR INPUT Section

This section adjusts the signal that is input from the 2TR IN jack (see page 20).

1 POWER Indicator

Lights up when the mixers power is on.

2 STEREO Level Meters

If the GROUP switch (4) is off, the left and right meters show the level to the ST OUT L and R jacks, respectively. If the GROUP switch is on, the left and right meters show the level to GROUP OUT jacks 1 and 2, respectively. The 0 position corresponds to the standard level. The PEAK indicator lights up red when the level hits the clipping point.

3 PFL-AFL Level Meters

If the GROUP switch (4) is off, these meters show the levels to the PHONES jack. If the GROUP switch is on, the left meter shows the level to GROUP OUT jack 3 and the right meter shows the level to GROUP OUT jack 4. The 0 position corresponds to the standard level. The PEAK indicator comes on red when the level hits the clipping point.
NOTE If signals are present on both the PFL and AFL buses, the PHONES jack will output the PFL signal only. Accordingly, these meters will indicate only the PFL level.

1 2TR IN Control

Adjusts the level of the signal from the 2TR IN jack into the ST bus.
2 PFL (Pre-Fader Listen) Switch
Use this switch to feed the signal from the 2TR IN jack, taken from before the 2TR IN control, 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 ( ).

4 GROUP Switch

Selects whether the meters show the GROUP levels or the ST and PFL/AFL levels. If the switch is on ( ), the four meters show the levels to GROUP OUT jacks 1 to 4, in order. If the switch is off ( ), the meters operate as described above.

I CHANNEL I/O Section

1 Monaural-Channel Input Jacks (MG32/14FX: CHs 1 to 24, MG24/14: CHs 1 to 16)
INPUT A These are balanced XLR input jacks. INPUT B These are balanced phone input jacks. You can connect either balanced or unbalanced phone plugs to these jacks.
NOTE On any given channel, you may use either INPUT A or INPUT B, but not both. If you connect to both of these inputs, only INPUT B will be effective.
3 Stereo-Channel Input Jacks (MG32/14FX: CHs 25/26, 27/28, 29/30, 31/32) (MG24/14FX: CHs 17/18, 19/20, 21/22, 23/24)
Phone jacks (MG32/14FX: CHs 25/26, 27/28, 29/30, 31/32) (MG24/14FX: CHs 17/18, 19/20, 21/22, 23/24) These are unbalanced phone input jacks. You can use each pair of jacks to input a stereo signal. Feed the L signal into the odd-numbered channel, and the R signal into the even-numbered channel. RCA-pin jacks (MG32/14FX: CHs 29/30, 31/32) (MG24/14FX: CHs 21/22, 23/24) These are unbalanced RCA-pin input jacks. You can use each pair of jacks to input a stereo signal. Feed the L signal into the odd-numbered channel, and the R signal into the even-numbered channel.
NOTE Where a channel provides both a phone jack and an RCA pin jack, you may use either one of these jacks but you may not use both at the same time. Please connect to only of these jacks on each channel. Some of the phone jacks (MG32/14FX: CHs 25/26, 27/28; MG24/14FX: CHs 17/18, 19/20) also support monaural input. Specically, if you input only into the L (MONO) jack of either pair (while leaving the R jack empty), the mixer will propagate the same signal through both the L (MONO) and R inputs.

2 INSERT I/O Jacks

These are unbalanced TRS (tip, ring, sleeve) phone-type bidirectional jacks. You can use these jacks to connect channels to devices such as graphic equalizers, compressors, and noise lters.
NOTE Connection to an INSERT I/O jack requires a special separately-sold insertion cable such as illustrated below. To the input jack of the external processor To the INSERT I/O jack Sleeve Sleeve Ring Tip To the output jack of the external processor Tip
