In this section, you can adjust equalization (frequency response), volume level, effect and monitor output levels for the input signal of each channel.

15 +15

2 Monitor controls (MONI)
For each channel, this controls the amount of signal that is sent to the MONITOR bus. The signal of the MONITOR bus is sent to the speakers connected to the POWER AMP 2 A/B jacks (only if the power amp select switch is in the MAIN-MONITOR position) and to the MONITOR jacks (input/output panel 6). Note: The signal is sent to the MONITOR bus from a location before the level control (4) of each channel. This means that it will not be affected by the setting of the LEVEL control.

3 Effect control (EFFECT)
For each channel, this controls the amount of signal that is sent to the EFFECT bus. The signal of the EFFECT bus is sent to the builtin effect and to the EFFECT OUT jacks (input/ output panel 3). Note: The signal is sent to the EFFECT bus from a location after the level control (4) of each channel. This means that the amount of signal that is sent to the EFFECT bus will be affected not only by the setting of the effect control, but also by the setting of the level control.
1 Equalizer controls (HIGH, MID, LOW)
This is a 3-band equalizer that adjusts the high frequency range, mid frequency range, and low frequency range of each channel. Response is at when the knobs are in the w position. Rotating it toward the right will boost the corresponding frequency band, and rotating it toward the left will cut it. The base frequency (or center frequency), range of boost or cut, and equalizer type of each band are as follows. HIGH: 12 kHz 15 dB shelving type MID: 2.5 kHz 15 dB peaking type LOW: 80 Hz 15 dB shelving type

4 Level control (LEVEL)

This adjusts the output level for each channel.
5 Pad switch (PAD) (Channel 14 only)
This switch attenuates the input signal by 30 dB. When connecting a line level device to channels 14, or if the mic input is distorted, turn this switch on (the pressed-in position).

s DIGITAL EFFECT section

This section allows you to turn the built-in digital effect on/off and to select the effect type.

Using the digital effect

The EMX660 has a built-in digital effect, allowing reverberation or ambiance to be added to vocals or instrumental sounds.
3 Turn the power on in the order of peripheral devices EMX660. Note: When turning the power off, reverse this sequence.
1 Press the DIGITAL EFFECT ON switch of
the DIGITAL EFFECT section.
2 Use the effect select switches of the DIGITAL EFFECT section to select the effect type. VO.ECHO 1, 2..Echo appropriate for vocals. VO.REV. 1, 2.Reverb appropriate for vocals. HALL 1, 2.Reverb typical of a hall. ROOM.Reverb typical of a room. PLATE..Plate echo-like reverberation
4 Set the MAIN section MASTER control to

the position.

5 While speaking into the mic (while playing the instrument), adjust the channel LEVEL control so that the 0 LED of the MAIN section peak level meter lights occasionally. Repeat this step for each channel.
3 Set the MAIN EFFECT RTN control to the

position.

4 Raise the EFFECT control of the channels
to which you wish to apply the digital effect.
6 If you wish to adjust the tone of each
channel, rotate the equalizer controls as desired.
5 Use the MAIN/MONITOR section EFFECT
RTN control to adjust the level of the sound processed by the effect. Note: If the effect sound is distorted even if the EFFECT RTN turned all the way down, lower the EFFECT controls of each channel.
7 Use the MAIN section graphic equalizer

to adjust the tone.

8 Use the MAIN MASTER control to adjust

the overall volume.

Example setups
This section provides some ways in which the EMX660 can be used, and explains connections and operation.
As a conference PA system/installed sound system
Here is an example of using the EMX660 as a conference PA system or as an installed sound system.

Main Speakers

Power AMP 1 A/B

Power AMP 2 A/B

Power amp select switch

Microphone

CD Player

Cassette Deck

Connections
Connect mics to channel inputs 16. If you wish to use an external device such as a CD player or LD player, connect the outputs of the device to the TAPE IN jacks of the EMX660. Note: A CD/LD player or cassette deck can also be connected to the LINE jacks of channel 5. If you wish to record the audio to a cassette deck, connect the REC OUT jacks of the EMX660 to the input jacks of the cassette deck. Connect the main speakers to the A/B jacks of the POWER AMP 1/2, and set the power amp select switch to "MAIN-MAIN."

Playing back a CD player

1 Turn the power on in the order of peripheral devices EMX660.
2 Adjust the MASTER control of the MAIN

section to the position.

3 Start playback on the CD player, and use
the MAIN section TAPE IN control to adjust the level so that the 0 LED of the MAIN section peak level meter does not light.

As a band PA

Here is an example of using the EMX660 as a small PA for a band. In this example, the monitor speakers are being sent a mix that is independent of the MAIN speaker mix. An external effect such as delay or reverb is also being used.
Connect mics or instruments, such as keyboards, to the channel input jacks 16. Connect the main speakers to the POWER AMP 1 A/B jacks, and connect the monitor speakers to the POWER AMP 2 A/B jacks. If you will be using an external effect such as delay or reverb, connect the EMX660s EFFECT OUT jack to the input jack of the external effect, and connect the output jack of the external effect to the EMX660s AUX IN jack.
Note: Set the power amp select switch of the POWER AMP section to the MAIN MONITOR position. If you are using an external effect, we recommend that you turn down the EFFECT RTN controls of the MAIN and MONITOR sections. If the external effect has a stereo output, it is possible to connect its output jacks to the LINE jacks of channels 5. However in this case, be sure that the EFFECT controls are turned all the way down for the channels into which the effect sound is being input. If the EFFECT controls are raised, feedback will occur, and your speakers may be damaged.

Effects Processor *1. Although this example shows an external effects processor and footswitch, which is used to turn on and Footswitch off the built-in digital effects process(YAMAHA FC5) or, connected to the EMX660, in practice, only one effects processor, internal or external, will be used at a time, so the footswitch is not required when using external effects.

Sending an independent mix to the monitor speakers
1 Set the MONITOR section MASTER control to the position.

Using an external effect

1 Raise the EFFECT controls for the channels
to which you want the external effect to be applied.
2 Raise the MONI controls for the channels
that you wish to hear from the monitor speakers. Note: The MONI controls are not affected by the level settings of each channel. This allows you to create a mix that is independent of the MAIN section.
2 Adjust the input level of the external
effect so that the sound is not distorted at the input of the external effect.
3 Use the MAIN section AUX IN control to
adjust the level of the sound processed by the effect.
3 Use the graphic equalizers and MASTER
controls of the MAIN/MONITOR sections to adjust the overall volume and tone.
