Apex GX230 2 30-Band Grafik-Equalizer

GX 230 Graphic Equaliser



Features

• DLT - technologie for perfectly flat amplitude and phase response
• 2 independent channels
• In/out switch for instant comparison with flat response
• 6/12 dB scale switches on graphic equaliser
• Selectable Butterworth 30 Hz high pass filters with 18 dB/octave slope
• 30 mm precision faders
• Comprehensive frontpanel lay-out
• Symmetrical in - and output
• Earth-lift switch
• Robust mechanical construction
• Constant Q design
• Available gain between in- and output: 6 dB
• Overload indicators: peak-peak sensing circuit giving overload indication for all circuits in the equaliser
• Failsafe bypass : The inputs are instantly connected to the outputs in case of power failure or power supply malfunction
• Extensive RF suppression
• XLR on in- and outputs
• Floating, transformerlike, electronically balanced output stages
• Power transformer with static screening for rejecting of power line interferences
