Thank you for your trust and for choosing the Impacto universal. To ensure an optimum listening
experience, we would like to give you a brief primer on how to use the Impacto universal. For detailed
operating instructions, please visit www.beyerdynamic.com/impacto-universal.
With the Impacto universal you can play high-resolution audio files up to 384 kHz / 32 bit (PCM) and
up to 5.6 MHz (DSD).
The Impacto universal is compatible with all headphones that provide ear cups on both sides to connect
mini jack plugs (3.5 mm) with a shaft diameter of 7.5 mm.
In combination with the T 1 (2nd Generation) and Amiron home headphones, the Impacto universal
meets the requirements of the EN 50332 European standard on Sound system equipment:
Headphones and earphones associated with personal music players – Maximum sound pressure level
measurement methodology. It is possible to connect other headphones to the two headphone
connectors, which may be louder than the limit value due to their technical specifications. Please
refer to the following section "Warning / hearing protection".
Warning / hearing protection
We would like to point out that listening at high volumes over a long period of time may
damage your hearing irreversibly. Therefore, reduce the volume before putting into operation
and when changing the audio source, as the connected devices or reproduced audio data can
have very different output levels.
Make sure that the set volume is not too high. Rule of thumb: The higher the volume, the
shorter the time of listening. According to employer's regulations for safety and health the noise
exposure e.g. when working should not exceed 85 dB (low volume). This is an allowed time of
listening of 8 hours at maximum. If the volume is increased by 3 dB, the allowed time of listening is
halved, i.e. with 88 dB the time of listening is 4 hours, with 91 dB 2 hours and so on.
