About Dynavox VT-80MK The VT-80MK is a HiFi compact amplifier for two analog stereo input sources, as well as digital input pos- sibilities (SD, USB, BT and Tuner). The music can optionally be playback via one and / or a second pair of loudspeakers or a headphone. Further equipment features are sound control (bass / treble). The signal from the currently selected source can be passed on to a further power amplifier or active subwoofer at the regu- lated and pre-amplified signal output (PRE-OUT). Thanks to its signal output on up to 4 loudspeakers, the VT-80MK is ideally suited for sounding a second room, a terrace, etc. The signal inputs for SD (cards), USB (sticks) and a BT data transmission also allows the playback of digital media. The small device dimensions make the VT-80MK to a space-saving amplifier for a small- up to a medium-sized stereo system.

Using lower impedances will damage the amplifier! SD/USB39 Analog Audio output of a computer Source Loudspeakers IiIIiIIi L R TYPICAL SETUP Mobile phone or Tablet Power Amplifier or Activ-Subwoofer IIIIIIII L R40 Establish the cable connection in the following sequence. Never change any cable connections while the unit is switched on! As connectors for inputs and outputs, there are mechanically identical RCA jacks, be careful not to mix up these connecti- ons during installation! Also make sure not to mix up inputs on the right and left. The RCA connectors are often marked as follows: red for the right chan- nel, black or white for the left channel. Make sure that all plug connections are in secure tightness. Inadequate connections can cause noise, failures, and malfunctions. Connection of source devices You can connect up to two stereo sources with RCA high-level output to the stereo RCA inputs "INPUT" (18/19). Use commercially available RCA cables. Often the output connectors of the source devices are labeled "LINE OUT". All two input connectors of this amplifier (AUX1, AUX2) are equivalent high-level inputs with RCA jacks. For SD/USB/BT/Tuner set the input selector to AUX3, you can insert and play digi- tal storage media to the "SD" (3) and "USB" (4), inputs provided for this purpose. Never pull the sto- rage media during operation! This may result the loss of data. To use the BT function or Tuner, use the button "MODE" to switch to the responding menu (If you have inserted memory storages at inputs 3 and 4, you may have to switch to the BT channel or Tuner by pressing the "MODE" button

CONNECTION AND COMMISSIONING41

(12) first). Now locate the amplifier in the list for available devices with your BT-compatible source device. You can find more information in the opera- ting instruction of your source device. The VT-80MK will appear in the list under the name "VT-80MK". After you have selected it, the connection will get confirmed acoustically. From now on, all audio signals are transmitted to the Dynavox VT-80MK. The wireless cross-link port (BT) can be deactivated (switched off) with the input selector (AUX IN). USB/SD The songs are played in the same sequence in which they were saved on the memory card USB/SD, no matter if they were saved in different folders. Choosing a special folder is not possible. The name of the actuallly played music title is shown in the display. In Mode RPT (Folder) you can repeat the folder content in which the actual played song is located. Tuner The Dynavox VT-80MK has got a simple integrated FM Tuner. Just like the digital inputs it can be selec- ted with the mode button with the input selector switch in position AUX3. With shortly pressing the play/pause button in tuner mode the autoscan of the channels starts. All found channels are saved and get a sequential channel number. This channel numbers can be selected with the number buttons on the remote control or by pressing the fast for- ward/backward buttons to reach the previous or next channel. Sorting or deleting of the channels is not possible. Connecting an additional power amplifier or active subwoofer The RCA jacks "PRE-OUT" (20), on the back of the

unit, can be used to add another output stage (eg for sounding a further room) or an active subwoofer to the volume controled Stereo output (line level), of the currently selected source. The output level of the pre-amplified output "PRE-OUT" (20) depends on the volume setting, the sound control (BASS, TREBLE) and the insertion of a headphone. Connect this signal output to the signal input ("LINE IN" / "INPUT" etc.) of the power amplifier / active sub- woofer using commercially available RCA cables. Connecting a headphone A headphone equipped with a 3.5 mm jack plug can be plugged into the headphone socket " " (9) on the front of the unit. All headphones with an impe- dance between 32 and 600 Ohm can be used. Unsuitable headphones with another impedance may damage the unit or produce an unexpectedly high volume that can damage your hearing. As long as a headphone is plugged in, the speakers are switched off. Before plugging in, be careful to redu- ce the volume of the "VOLUME" knob (11) (this knob is also used to adjust the volume of the head- phone). Connecting the speakers Use cables with sufficient cable cross-section to con- nect your speakers to the VT-80MK. Ensure that bare loudspeaker wires can never touch each other or the back of the housing! No active speakers may be con- nected! Use only speakers with a nominal impedance of 4 - 8 Ohm. In addition, you have the possibility to operate the amplifier with 4 loudspeakers. For this, only use speakers with a nominal impedance of 8 -43

CONNECTION AND COMMISSIONING

16 Ohm. Using speakers with a different nominal impedance will damage the amplifier. For each loud- speaker (R: right or L: left), you will find on the back oft he unit two loudspeaker terminals (21) (positive + and negative -), which are connected to one side of a loudspeaker cable. There are similar connections on the loudspeaker, as is the polarity. The other end of the speaker cable assigned to the loudspeaker is connected here. The loudspeaker cable must be con- nected to the same terminals: the "+" marked termi- nal on the amplifier must lead to the "+" marked connection of the loudspeaker. The loudspeaker cables are fitted without connectors. Remove an approximately 1 cm long piece of insulation from each end of the double cable. Twist the bare strand to avoid mutual shorts. Rotate the screw of the loud- speaker clamp counterclockwise to open the clamp contacts and insert the bare wire end into the clamp hole. Now turn the screw connection of the loud- speaker clamp clockwise again in order to tighten the wire in the loudspeaker clamp. You can check that the cable is correctly seated by pulling it lightly. In case you use pre-assembled speaker cables with 4 mm banana plugs, simply plug them into the bana- na holder of the loudspeaker clamp. Make sure that the polarity is correct. Volume control Ther volume setting with the remote control is only for input channel AUX3 (USB/SD/BT/Tuner). The volu- me can be set in steps of 0-30 and is an additional volume control to the master volume knob on the front of the device. This means the max. volume of 30 is always limitted by the master volume. If the44 volume is set to 30, it still can be increased (decrea- sed) with the master volume knob, if this one is not yet set to max. volume (min. volume). Apart from that the volume can be changed by BT sources (e.g. smartphone or tablet) in BT mode. The volume of the analog inputs AUX1 and AUX2 can only be set by the master volume knob. Connection of the mains cable Lastly, connect the double-groove plug of the power cable to the double-groove power supply socket (22) of the amplifier. Plug the power cord into an electrical outlet that is supplied with a suitable vol- tage (230 V / 50 Hz). Make sure that the plug in the item, as well as in the electrical outlet are secure. Do not turn the unit on until the volume control (11) has been adjusted to the minimum volume.
