Setting up GEQ by Music Playback Measurement

This explains how to output music playback (such as from a CD

player) via channels 15/16, pick up that signal picked from a

microphone plugged into channel 1, and measure the frequency

characteristics.

Connect the EMX to a set of speakers. Connect a

microphone to channel 1 INPUT A or INPUT B, and

place the microphone at the point to be measured.

Connect a CD player to channels 15/16.

Set up channels 1 and 15/16 as follows, and lower

the ST Master fader all the way down.

●

Channel 1

●

Channels 15/16

* Adjust these settings in step 4.

•Make sure that all faders other than channels 1 and

15/16 are set to their minimum and that no other

signals are input.

• Set the POWER AMP switch to L/R.

Press and hold the MEASURE/CORRECT switch

for three seconds or longer. The indicator begins

ﬂashing slowly, and measurement of the frequency

characteristics starts.

To adjust the playback level of the CD player, turn

on the channel 15/16 PFL switch, adjust the GAIN

control so that the LEVEL meter 0 ﬂashes occasion-

ally, set the channel faders to the 0dB position, and

then adjust the ST Master fader.

To adjust the channel 1 input level, turn on the PFL

switch, adjust the [26dB] switch and GAIN control

so that the LEVEL meter 0 ﬂashes occasionally, and

set the channel faders to the 0dB position.

The measurement result is updated on the GEQ dis-

play every ﬁve seconds after measurement starts.

Conﬁrm that the measurement result is consistent,

and then press the MEASURE/CORRECT switch to

suspend the measurement.

The result is retained even after suspension. At this

time, the GEQ display indications ﬂash.

This step is also handy for altering the location of the

speakers and microphone, since the noise output is

muted during the suspension. To resume the measure-

ment, press the MEASURE/CORRECT switch again.

Turn off the channels 1 and 15/16 ON switches and

lower the channel fader all the way down. Leaving

the fader up and stopping the measurement in the

step below can result in howling.

Press the MEASURE/CORRECT switch for two

seconds or longer to apply the correction curve to the

GEQ according to the frequency characteristics of

the measurement result.

The MEASURE/CORRECT switch indicator

ﬂashes. Also, the GEQ ON switch lights up so that

the GEQ is enabled.

To prevent clipping at the power amp stage by exces-

sive equalization, the correction curve is never set

over ±6dB.

If necessary, and adjust the GEQ settings using the

GEQ +/– switches. If you adjust the GEQ settings,

the FRC indicator turns off. To restore the correction

curve immediately after measurement, press the

FRC MEASURE/CORRECT switch again. The

indicator lights up.

If necessary, store the GEQ settings to a USER

switch.
