desired, it is probable that any EQ encoder choices made before the alteration in 
range will require resetting.  Range selection for each channel is global and is 
applied to all channel EQ encoders. 

 

HI Q 

  Normal Q (Q

? ? ?? ? ?

 of the DEQ 624 is divided into bandwidths of 1/3

rd

 octave from 

20 

Hz 

to 20 

kHz

.  HI Q (Q

? ? ? ?? ? ?

 resets the bandwidth to 1/8

th

 octave.  The center 

frequencies remain unchanged while the effect on adjacent frequencies is less 
pronounced in HI Q.  Pressing the HI Q switch lights the switch and indicates HI Q is 
now available to be selected.  A row of 31 Red LED’s labeled HI Q can be found on 
the Graphic Equalizer section between the two rows of digital encoders.  These are 
the HI Q Active indicators, which do not light unless a frequency has been selected for 
applying HI Q.

  Begin by pressing the Channel A HI Q switch.   This will light the Channel A HI 

Q switch in the Dynamics / Master Control section.  This enables HI Q select 
/deselect mode for Channel A and 

disables Channel B HI Q switch and the 

Preset switch

.  Any HI Q Active LED’s below any of the Channel A equalizer 

encoders in the Graphic Equalizer section that have HI Q enabled will now be lit.  

  The Graphic EQ section digital encoders are used to enable or disable HI Q.  The 

speed at which the encoder is moved is used to select it for HI Q mode.  Moving 
the encoder slowly does not select the encoder for HI Q but rather allows it to be 
read and updated normally.  Moving the encoder quickly causes the Red HI Q 
Active LED beneath the encoder to blink and the Store / Security switch in the 
lower right-hand corner of the faceplate to blink.  Pressing the Store / Security 
switch at this time latches the selected EQ encoder into HI Q.  The HI Q Active 
LED beneath the selected encoder stops blinking and remains ON indicating the 
encoder is now in HI Q and the Store / Security switch light goes off.  Adjusting 
the EQ encoder in HI Q mode results in a more focused manipulation of the 
selected frequency with reduced effect on adjacent frequencies.
