"Building on 20 years of EQ design and manufacture, ARX once again redefines the standard for Graphic Equalizers with the all-new EQ215!"


  • New XR logo (Extended Resolution) long-throw faders for maximum control and resolution, with integrated protective dust cover
  • New Sweepable High Pass filter 20-200Hz
  • Ultra low noise and accurate 'Constant Q' circuitry
  • Balanced Inputs and Outputs on XLR and Jack connectors
  • Switchable 6dB or 15dB cut and boost
  • Audio Ground lift switch on rear
  • Intuitive controls
  • User friendly layout

...and most of all, flawless performance in any audio environment

Sometimes a 10 band Graphic Equalizer isn't enough, but a 30 band EQ is overkill. Well, for times like these, we've designed the ARX EQ215. It's a dual channel 15 band Graphic Equalizer built to the same exacting standards as our EQ260, but designed especially for applications where the program material is predominantly pre-recorded and pre-processed.

Typical applications are, for example, in DJ systems, Karaoke bars, home theatre, project and budget studio control rooms, and home stereo systems
Delivering flawless professional performance, it takes up minimal rack space being neatly housed in a compact 2 RU all steel chassis.

Quality you can feel as well as hear
On the EQ215 's front panel, each channel has 15 of our new Extended Resolution long throw, centre grounding faders, switchable to either ±15dB or ±6dB, for the ideal combination of high fader resolution and maximum cut and boost. A protective dust cover is also fitted to each fader.
As well, there is a Gain recovery control with up to +10 dB of gain; a Clip LED to indicate circuit overload, a sweepable 20-200Hz High Pass filter, and an IN/OUT hardwire bypass switch which removes the EQ215 completely from the signal path.

Accurate Constant Q Circuitry
Internally, the EQ215 features innovative Constant Q circuitry.
What makes this so good? Well, it means that the graphical representation of the sliders on the front panel more accurately reflects the changes you are making to the sound, as compared to the very rough approximation you get with many traditional graphic EQ designs.
In other words, 'what you see is what you get.'
Combine this with the EQ215 's ultra low noise circuitry, and you have an equalizer that is unsurpassed for total accuracy.
Additionally, at the 0dB slider position each filter is, in effect, removed from the circuit to further enhance the EQ215 's low noise figures.

Balanced Inputs and Outputs
On the rear panel, each channel of the EQ215 has true differential Balanced Inputs and Servo Balanced Outputs, with both XLR as well as convenient TRS balanced jack connectors.
There is also an audio ground lift switch to isolate the audio ground from the chassis ground.

Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a removable power lead and standard 3 pin IEC connector, with built-in fuse and voltage switch.

When you need superlative, uncompromising audio quality but can't justify the use of a dual 30 band EQ such as the EQ260, we belive the EQ215 is the only graphic equalizer to choose.
With its compact High Density design, clean good looks and precision electronics, the ARX EQ215 will truly enhance any pro audio application. 


You'll never compromise on Quality when you choose ARX
