The unit is suitable for indoor use only. Protect it against dripping water, splash water and high air humidity. The admissible ambient temperature range is 0 – 40 °C.

For cleaning only use a dry soft cloth; never use water or chemicals.

No guarantee claims for the unit and no li- ability for any resulting personal damage or material damage will be accepted if the unit is used for other purposes than originally intended, if it is not correctly connected or operated, or if it is not repaired in an expert way. Likewise, no liability will be accepted for data loss caused by a defect or operating errors and for any consequential damage of this data loss. If the unit is to be put out of operation definitively, take it to a local recycling plant for a disposal which is not harmful to the environment.9 English 3 Applications The MXT-52MP3 is a monophonic audio mixer for sound reinforcement systems (e. g. PA sys- tems). It is designed for wall and furniture in- stallation. The mixer provides five inputs. Two of these inputs can be used for the connection of microphones; they provide a switchable phan- tom power supply that is required for electret microphones, for example. Three inputs can be used for the connection of stereo audio sources such as CD players, for example. In addition, the mixer features an integrated audio player for the replay of audio files from a USB flash drive or SD/ MMC memory card. An infrared remote control for the audio player is provided. 4 Installation The mixer is designed for installation into walls or furniture. The dimensions of the unit can be found in figure 2 on page 2. The four holes of the front plate can be used to fasten the mixer. Prior to installation, make the connections on the rear side of the unit.

4.1 Making connections on the rear side

To connect the power supply and the amplifier, open the housing: Remove the screws 🄰 of the front plate. Guide the connection cables through the hole on the rear side and make the connections. Then close the housing. OUTPUT

24 V17 18 Connections for amplifier and power supply

Connect the input of the amplifier to the termi- nals of the balanced signal output (17) (fig.3, OUTPUT).

Connect a 24 V power supply unit with a per- manent rating of 250 mV to the terminals (18). DC voltage supply or AC voltage supply can be used. Consequently, the polarity does not matter when a DC voltage source is used.

The terminal screw on the rear side of the unit can be used as ground connection. This may be necessary when, for example, the mixer is used together with an amplifier that is not connected to ground and hum noise occurs.

4.2 Making connections on the

Monophonic signals of microphones or audio sources with line level can be fed in via XLR plugs connected to the jack MIC / LINE 1 or MIC / LINE 2 (11). The jacks are designed for balanced signals. Audio sources with unbalanced signals can be connected via an XLR plug where the contacts 1 and 3 are connected with each other. Use a small screwdriver to turn the GAIN control (10) towards “+” (for microphones) or “−” (for audio sources with line level). If required, readjust the control during operation. (When the volume of the sound via this input is too low, turn the control clockwise; when the sound is distorted, turn the control anti-clock- wise.) Phantom power supply When an audio source (e. g. electret micro- phone) requires phantom power supply, engage the switch PH. PWR (12) of the corresponding XLR jack: The phantom power (⎓19 V) for the jack will be activated. Caution:1. To avoid loud switching noise, only use the switch when the mixer or amplifier is switched off. Never connect an audio source with unbalanced signal output to the XLR jack when the phantom power supply has been activated; otherwise, the audio source may be damaged.

4.2.2 Stereo audio sources

Connect units with a stereo output (e. g. CD player, tuner) to the RCA jacks LINE 3/4 (13) or to the 3.5 mm jack AUX (14). The mixer is mono- phonic; therefore, the left and the right stereo channels will be mixed to a mono signal.10 English

To insert the batteries (2 × 1.5 V, size AAA), remove the battery compartment cover on the rear side of the remote control. Insert the batteries as indicated in the compartment. Close the cover. If the remote control is not used for a longer time, remove the batteries as a pre- caution so that the remote control will not be damaged in case the batteries should leak. When the operating range of the remote control decreases, the batteries are discharged and must be replaced. Discharged batteries must not be placed in the household waste; always take them to a special waste disposal, e. g. collection container at your retailer. 5 Operation

1) Prior to initial switch-on, set all volume con-

trols (5, 7, 9) to “0” to avoid an unexpectedly high volume when the unit is switched on.

2) Switch on the audio sources connected.

3) Use the POWER switch (16) to switch on the

MXT-52MP3. The power indicator ON (15) will light up.

4) Switch on the amplifier connected.

Replay music, for example, from an audio source or speak into a microphone (operation of the audio player

chapters 5.1 and 5.2)

6) To adjust the volume of the audio sources,

nection. To adjust the volume of the audio player, use the volume control MP3 (7) or the remote control (

Adjust the total volume with the control VOL- UME (9). When the output is overloaded, the signal will be distorted and the LED indi- cator CLIP (6) will light up. In this case, turn back the control of the corresponding audio source or the control VOLUME accordingly.

Use the controls (8) BASS and TREBLE to adjust the tone as desired.

The integrated audio player is able to replay audio files in the formats MP3 and WMA. As storage media, USB flash drives or SD[HC] mem- ory cards (also MMC cards) can be used. Note: Due to the large number of storage device manu-facturers and device drivers, it cannot be guaranteed that all storage media are compatible with the audio player. Connect a USB flash drive to the USB port (2) or / and insert a memory card (contacts facing upwards) into the slot (3) until it engages. To remove the card, slightly push the card into the slot until it disengages. When the unit is switched on, the replay of the audio file most recently replayed will start. When a storage medium is connected during operation, the replay will start from this medi- um. The LED indicator at the connection of the storage medium currently used will light up. The audio player can be operated via the but- tons (4) or the remote control supplied (fig.4)

always point the remote control to the audio player. Make sure that there are no obstacles between the remote control and the audio player. The display (1) will indicate the storage medium selected (USB /CARD), the number of the current title and the file type (MP3 / WMA). When the replay is started or when a title in a different folder is selected, the number of the folder will be briefly indicated ( xx). The volume of the replay depends both on VOL− /+ on the remote control and on the volume control MP3 (7).11 English
