EQ215A 15 band Stereo/ Dual Mono Equalizer 19" Rack Mountable
The EQ215A is a stereo or dual mono 15 band 2/3 octave graphic equalizer. The unit 
incorporates constant-Q circuitry with a 5% center frequency accuracy. Constructed in a strong metal housing, and with a whole range of features built in, this unit represents great value for both the enthusiast and the professional.

Variable High Pass Filter
The EQ215A includes a variable High Pass Filter (HPF) which can be used to filter out unwanted low freqencies from the channel 1 and 2 outputs. This means that low frequencies will only go to the sub output and your Front of House or Monitor speakers won't recieve bass frequencies that they can't handle, resulting in more efficient operation.

Subwoofer Output with Switchable Crossover Frequency
This version of the EQ215A includes a subwoofer output with a Low Pass Filter (LPF) that has 3 selectable cut-off frequencies, 80Hz, 100Hz and 120Hz. When combined with the HPF you have a crossover that you can tune to suit your speakers. This means the input signal is split into mids and high frequencies for the speakers connected to the channel outputs and low frequencies for the sub output.  

When to Use a Graphic EQ
Graphic EQ's are essential for live sound engineering, and are a vital tool for PA systems in any acoustic space. They are used to treat a Main Mix or Foldback Monitor output signal and tailor the sound to suit the room. An Equalizer provides the means to "cut" or reduce frequencies that may cause feedback on stage, or in the room, and eliminate unpleasant and harmful frequencies in the PA system.
