【HEC HD-Audio USB-DSP-ULTRA｜DSP amplifier with USB input】

The HEC HD-Audio USB-DSP-ULTRA is designed for those who want to enjoy the audio from a smartphone or PC as high-quality as possible even in the car. It accepts digital audio signals via the USB mini-B connector, and supports USB-OTG output from smartphones and portable players, as well as PCM stereo signals from a PC.

Since it supports PCM signals up to 192kHz / 32bit, using a compatible source makes it easier to build a playback environment in the vehicle that leverages the amount of information in the music data. This is a DSP amplifier worth considering for anyone who wants to enjoy even the music they always listen to with careful attention to subtle sonic details and vocal imaging.

However, the sound is not determined by adding the DSP amplifier alone. The overall impression changes depending on combinations with the vehicle’s factory audio and speakers, how power and wiring are handled, and how the sound is tuned to suit the cabin. At LOGON, we work out a reasonable configuration together while confirming what source you want to focus on and how much of the factory system you want to keep using.

Also, to adjust the volume with this unit, you need the separately sold remote control DIRECTOR or URC-3. If you want to use a smartphone or PC as your audio source, or if you’d like to fine-tune the sound in your car even further, please consult us while checking your vehicle model and your current audio setup.
