Featuring a full ten bands of powerful, flexible parametric EQ in a tiny bus-powered package, the IL-DSP is the mobile audiophile's perfect companion for laptop, tablet, or smartphone (macOS, Windows and Android supported). The inbuilt microphone for voice-calling ensures maximum mobile flexibility.

Housed in a light-weight aluminum enclosure, the IL-DSP sports impeccable audio specifications of 120 dB signal-to-noise ratio and 0.0007% THD+N (mid-gain). 30 mW power output per channel is ample for IEMs and most portable headphones. High-resolution PCM and DSD formats are both supported.

The ten bands of parametric EQ are configured with miniDSP's easy-to-use computer interface. The fully adjustable peaking and shelving filters allow adjustment of the audio band from the narrowest to the broadest control ranges, with up to 16 dB boost or cut in each band.

Analog audio specifications

In this app note, we will walk through EQ-ing your headphone based on measurements taken with the miniDSP EARS measurement rig.

To implement the EQ, the app note will assume that you have a miniDSP HA-DSP headphone amplifier or another miniDSP device such as the 2x4 HD. However, the technique can be used with many other devices and also with software implementations, as long as they have a full parametric EQ capability.

For devices that don't have a full parametric EQ or that can't have an REW measurement signal run through them, see the related app note Headphone EQ for iPhone (or Android, or DAP).
