Safety instructions 2 Safety instructions Intended use This device is used to amplify and mix the signals of audio equipment and musical instruments for the output to the connected headphones. Use the device only as described in this user manual. Any other use or use under other operating conditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.
Safety instructions Safety DANGER! Danger for children Ensure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the unit. They could swallow the pieces and choke! Never let children unattended use electrical devices. DANGER! Electric shock caused by high voltages inside Within the device there are areas where high voltages may be present.
Safety instructions CAUTION! Possible hearing damage With loudspeakers or headphones connected, the device can produce volume levels that may cause temporary or permanent hearing impairment. Do not operate the device permanently at a high volume level. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment. NOTICE! Risk of fire Do not cover the device nor any ventilation slots. Do not place the device near any direct heat source.
Safety instructions NOTICE! Operating conditions This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and strong vibrations. NOTICE! External power supply The device is powered by an external power supply.
Safety instructions NOTICE! Possible staining The plasticiser contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate or PVC floor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the floor, but use felt-pad floor protectors or a carpet.
Installation and starting up 3 Installation and starting up Unpack and carefully check that there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the device against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively. Establish all connections as long as the unit is switched off.
Installation and starting up Operating voltage supply Use the included AC adapter to connect the device via the [DC 9V] jack to an AC outlet. For optional battery operation, open the battery compartment on the left side of the housing and insert a 9 V battery (not supplied) into the battery compartment. Close the compartment. 3.1 Pin assignment Jack plugs for signal inputs The figures and tables show the pin assignments of 1/4" phone plugs.

Connections and operating elements 4 Connections and operating elements Front panel headphone amplifier 16
Connections and operating elements 1 [BATT.CHECK] Green LED of the battery indicator. 2 [BATT.CHECK] Red LED of the battery indicator. 3 [MODE-SWITCH] Operating mode switch. 4 [BALANCE] Balance control to set the volume ratio of left and right input signal. 5 [VOLUME] Volume control to set the output level. 6 [OUTPUT] Headphones output (3.5 mm mini phone socket, stereo).
Connections and operating elements Rear panel 7 [INPUT (R)] Balanced XLR / 1/4" TRS combo jack for connecting the right input signal. 8 [INPUT (L)] Balanced XLR / 1/4" TRS combo jack for connecting the left input signal.
Connections and operating elements 9 Battery compartment with cover. 10 [DC 9V] Connector for the supplied power adapter. 11 [POWER ON | OFF] On / off switch.
Functions 5 Functions Checking battery status The two [BATT.CHECK] indicators show the status of an inserted battery. With a new battery or a newly charged rechargeable battery only the green LED lights. When after a few hours of operation the battery power decreases below about 7.3 V, both indicators (green and red) light up. If only the red LED lights up, the battery voltage has dropped to about 6.5 V. Then the bat‐ tery needs to be replaced or recharged.
Functions Optimizing the input level Adjust the level on the signal source from which the device gets the signal (e. g. the mixing console) to about 0 ~ 3 dB in signal peaks. Such an input signal ensures a sufficiently powerful output signal for the headphones connected to the unit. In addition, you prevent a sharp increase of the headphone level at high rising signal levels, that e. g. may be caused by feed‐ back. The device limits the input signal at about +5 dBm.
Technical specifications 6 Technical specifications Audio inputs 2 × XLR / 1/4" TRS jacks (balanced) Input impedance: 15 kΩ Nom.

Protecting the environment 7 Protecting the environment Disposal of the packaging mate‐ rial For the transport and protective packaging, environmentally friendly materials have been chosen that can be supplied to normal recycling. Ensure that plastic bags, packaging, etc. are properly disposed of. Do not just dispose of these materials with your normal household waste, but make sure that they are collected for recycling. Please follow the notes and markings on the packaging.
