OVERVIEW
The IL-DSP is a tiny USB-powered portable headphone amplifier and DAC
(digital-to-analog convertor). It provides high-fidelity playback of all audio and
music sources from phones, tablets and computers.
Technical performance of the IL-DSP is exemplary, with PCM digital audio
playback up to 24-bit 192 kHz
1
, 0.0007% THD and 120 dBA signal-to-noise
ratio.
30 mW power output per channel is ample for IEMs and most portable
headphones. High-resolution PCM and DSD formats are both supported1.
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. This combination of DSP
power, careful selection of high-quality components and a 32-bit audiophile
DAC combine to create an unparalleled portable headphone experience.

DSP parametric EQ operates for PCM input sample rates up to 96 kHz. DSP paramet-
ric EQ does not operate for PCM input sample rates of 176.4 and 192 kHz, or for DSD
input.
