  FEATURES
 

The EQ30 Series were designed to meet the needs of the most demanding sound reinforcementenviron ments, while o f fering the simplicity of straight forward controls. The E Q 30 provides standard features like dual channels, 15 2/3 octave bands, ISO frequencycenters, +/-12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also incl
udes other thoughtful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain a d j us tme n t s ; XLR,barrier strip, and 1/4'' TRS connectors for installation ease; balanced inputs and outputs for quietoperation; and chassis/ signal ground lift capabilities for quick hum isolation. The visionary design of the Bostonaudio EQ30
makes your job easier .

   
  REVOLUTIONARY ENGINEERING
 

The Bostonaudio EQ 30 Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transforme r , electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and powe r -o f f hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel
crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 2U
steel/aluminum chassis.
