Heilbronn, 23rd November 2017: To enjoy music of the highest quality when on the move, a high-resolution audio player is essential – and of course good headphones. Plus, a smartphone is also needed for calls. All in all, that’s quite a few devices. An easier and simpler solution however is the Impacto universal from beyerdynamic.

The ultra-compact D/A converter and headphone amplifier (EUR 379) turns the smartphone itself into the hi-res player. It docks onto the USB or Lightning connector and supplies three of the best beyerdynamic headphones with audiophile sound: the Amiron home, the present reference T 1 (2nd generation) and its portable variant, the T 5 p (2nd generation). What’s more, when on the move with their notebooks, mobile users can also connect their Impacto to their computer. The required cable with large USB plug (Type A and Type C) comes included.

Concentrated sound: High-end DAC in the headphone cable

The low weight of the converter is a mini sensation in itself. At just twelve grams, it’s barely noticeable to the wearer – also because the DAC is directly built into the headphone cable. A series of measures are to thank for this light-hearted listening pleasure. For example, beyerdynamic uses no screws. Instead, the audio specialist from Heilbronn welds the housing by means of ultrasound and coats the illuminated keys with a soft material that’s pleasant to the touch. This creates a seamless surface, which prevents dirt from entering the housing.

A special cable material makes the leads especially flexible and supple. This was developed specially by beyerdynamic for use on the Impacto. The cables otherwise used on USB devices are too rigid and not resilient enough for permanent mobile use.

Universal talent: Made for iPhone – and Android

The Impacto universal differs from the previously available Impacto essential (EUR 329) due to its Apple certification. iPhone or iPad users can connect it directly to their iOS device and enjoy music in unprecedented quality. beyerdynamic includes the power supply battery in the delivery too. Elegant and well thought out like the Impacto universal itself, it adheres magnetically to the rear of the 7 millimetre thin DAC housing.

The battery is not required for operation on Android smartphones. For those, power is supplied via the micro USB or USB C cable (USB On-The-Go), which come included. Owners of an Impacto essential can however also purchase the battery pack as an accessory (EUR 59). The energy storage unburdens the smartphone battery and thus extends the playing time.

Maximum resolution: Hi-res playback up to 32 bit / 384 kHz

When compared with stationary high-end systems, the inner technology effortlessly stands up. The Sabre32 Mobile Reference DACTM decrypts high-resolution audio signals up to a resolution of 32 bits and 384 kilohertz. This device class typically achieves values of 24 bit/192 kHz. The mobile digital-analogue converter even supports DSD signals (Direct Stream Digital) of 2.8 and 5.6 megahertz. The DAC uses a hi-res LED as a control function. When it lights up, the player is indeed sending high-resolution audio information to the converter. Users can select their preferred hi-res player app as a playback program.

This means that the sound quality no longer depends on the components of the playback device. Instead, the DAC converts the high-resolution music data back to analogue format and amplifies it – with a precision that takes full advantage of the acoustic potential of the headphones used. The high-performance headphone amplifier can supply even 600 ohm converters as in the T 1 without restriction. In other words, all that's needed to enjoy music in the highest quality is a high-end headphone from beyerdynamic and the Impacto universal.

The Impacto universal is available from December in authorised specialist stores and online at www.beyerdynamic.com. The Impacto universal can be tested at CES in Las Vegas from 9 to 12 January 2018 at beyerdynamic's booth #21630.
