Apex PE232 MKII 2 30-Band Paragraphic-EQ

PE 232MKII Paragraphic Equaliser

PE 232 is a combination 2x30 band graphic equaliser with 2 parametric equalisers.



Features

• a combination of a 2x30 band graphic eq with a 2-band parametric eq
• Graphic equalisers are "constant-Q" for better combining of filters
• Gain graphic equalisers : switchable +-12 dB or +- 6 dB for higher resolution.
• DLT : Dynamic Laser Trimming for absolute flat amplitude and phase response
• 30 ISO center frequencies : 25Hz - 25KHz, 1/3 octave
• All filters can be put individually in/out of the circuitry allowing for comparison between the equalised and the flat signal.
• Parametric filters with a gain of -&(typically -45 dB) to + 15 dB for removal of unwanted noises.
• Parametric filters with a frequency response of 18Hz - 20KHz
• Parametric filtes with variable width (Q) for optimum filter definition
• Variable High Pass filter (HP)to protect amplifiers and speakers
• LED overload indication sensing the whole circuitry (not only in - or output)
• Rugged chassis with extra metal framework behind frontpanel to avoid torsion of the circuit boards
• In - and outputs are connected in case of power failure.

  Electronically balanced and floating, simulating transformer output with app. 10 KOhm to ground impedance for each leg
  
  Max level: +21 dBm into 600 Ohms
  
  Impedance: 51 Ohms (each leg)
  
  Output symmetry balance better than 65dB (20Hz-20KHz IEC)
  
  XLR-3 type connector
  
    connections: 1 signal ground; 2 hot (+); 3 cold (-)
• Performance
  
  frequency responce: +0 -0,5dB, 20Hz-40KHz (graphic eq IN)
  
  THD:<.01% (20Hz-20KHZ)

• Filters
  
  Graphic aqualiser:
  
     30 ISO center frequencies: 25Hz-20KHz 1/3 octave
  
     Center frequency tolerance: +-1% (typically better than +-0.5%)
  
     Q tolerance: +-1%
  
     Max boost/cut: 6 or 12dB +-0.5dB reciprocal
  
     Switchable
  
  Parametric filters
