OVERVIEW

 

6

 

3-Band Parametric Equalizer.  

Total tonal control is what the Equalizer 

section provides.  The EQ will let you fine tune the sound to suit your taste 
with exacting precision.

  

 

Bypass Switch.

   A bypass switch is provided to audition the signal in 

an equalized version as compared to a direct unaffected signal. 

 

Variable Q

.  Adjusts the width of the frequency band between wide and 

narrow during equalization.  

 

EQ

COMP.

   Switches the order of the signal chain putting EQ before 

the Compressor. 

Master Section 

 

Gain Reduction to Meter. 

Shows gain reduction on the meter 

implemented by the compressor.

 

 

Level.

  The output of the EUREKA is adjusted by the Level control and 

is useful for compensating for gain loss due to compression or to 
decrease output signal that boosting frequencies with the Equalizer 
section may have caused.  The output is variable from –80 dB to +10 
dB.

 

 

VU Meter.  

The VU meter provides an accurate reading of the output 

level and a reference of signal presence. It can also be switched to 
monitor gain reduction when using the compressor.
