1. Clues for users.
- Before putting the amplifier to the 230V currency, please read the following instruction.
-Doing any unknown service to the device by any unauthorized persons makes the depriving of guarantee
and can be the cause of the worsening of technical parameters and the safety of using.
-ATTENTION! The device must be supplied from the plug-in socket with the safety circuit connected
(Socket with grounding wheel).
-In case of changing the plug-in fuse, the plug must be pulled off.
-The producer can introduce some changing to the device in case of modernizations or technical progress,
without the necessity to put them into the instruction as far as the basic parameters, that are included in this
instruction, are not changed.
The accessories of the amplifier:
-service manual with the guarantee card,
-spare fuse,
-plug-in cable,
-application software CD
2. Using and general notices
The modern amplifiers AMWL- DSP1A(Powermixer) are designed to be used in sacral buildings, large, closed
areas, conference rooms, where the high quality and the hearing of speaking is required. They are cooperating
with the 50V, 70V and 100V loud speakers line and with the loud speakers set of altogether impedance > = 4
?.The amplifier has got: 8 symmetrical microphone – line channels to put in the dynamic, capacitive and
wireless microphones or the device with line level output and music channel to put in the record player, tuner or
CD player (LINE – asymmetrical). To record, there is a separate RCA (RECORD) socket.
AMWL-DSP1A is a modern amplifier equipped in signaling DSP processor that enables precise correction of
sound characteristics in buildings with very difficult acoustic conditions. The amplifier activates only those
microphones, that are used in that moment, what eliminates sound surrounding influence coming from not used
microphone channels.
Each 1-8 channel is equipped in symmetrical XLR input, sensitivity regulation, Phantom power plugged in,
microphone/line switch, 100Hz high – pass filter, preamplification regulation, and timbre regulation
(bas/soprano) designed in front of the case. In 1-8 channels, diodes signal the channel activity and the
microphone transposition. The amplifier is equipped with an MP3 player with remote control and an
which eliminate sibilance during the speech.

5. Amplifier’s menu control..
After amplifier’s connection to 230V currency by a given cable and power input (switch no 15), our company’s logo
appears, and after several seconds, there is a note: “MWL Control” “Preset 1” ( or “Preset 2”).
For the display menu control, there is a pulser’s handwheel ( 7 ) – to come into the settings mode – press it. Then,
there is a next note – “Gain”.
Turning the handwheel left or right, there are other menu’s parts ( previous or next parts). To come into the chosen
part – press handwheel ( 7 ) (ENTER).
To come back to the previous part – press ( EXIT) ( 9 ).
Menu structur

Amplifier’s control – settings by the computer
All settings introduced by the amplifier’s control panel can be also done by the PC computer. To get the
possibility of the amplifier control by the computer, the program MWL Control must be installed ( it is on the
CD added). MWL Control program is created only for the configurations of MWL-DSP1 andAMWL- DSP1
series.
Licensor is not responsible for any harm of the program operation or for the wrong use of the program.
MWL Control program is on the CD which is given together with the amplifier. To install the program on
the computer, put the CD inside the CD-ROM, than, start it by installation folder and follow the
instructions.
When the installation is done, connect the amplifier with the computer and start the MWL Control
program. Connect the amplifier by the cable from socket no 8 on the front panel to the USB socket in the
computer and than, turn on the power – switch (15). When the program starts, open “Settings” on the
menu and choose “Connection”. After the “ Settings of the device” is shown, click on “Scan” to find the
port, where the amplifier is installed. After scanning the ports, there is a note: “ MWL is found on the port
no …”

After closing the windows ( click on “OK” on every window), the amplifier connects with the program
automatically. If the amplifier’s settings are saved with the password, there will be a window to introduce
it – there is no possibility to change any configuration without introducing the password.
