Backlit standby button.
Red = Device is in standby mode.
Green = Device is turned on.
Infrared diode to receive the signals, which are transmitted via the remote control.
Headphone sockets, connected in parallel, 1/4" stereo jack (6.35 mm).
In order to connect standard headphones.
Important:
As the headphone sockets are connected in parallel, the volume is controlled for both headphones.
Therefore, we recommend using only headphones of the same impedance to achieve the same volume for both
headphones.
Backlit button to select input 1 and transmitting the signal of the device connected to input 1.
Orange = Input 1 is active.
Backlit button to select input 2 and transmitting the signal of the device connected to input 2.
Orange = Input 2 is active.
Volume control to adjust the volume.
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.
