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 AMC- DSP4 (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 Ù.
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-DSP 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.

5. 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 MWLEasy Manager must be installed ( it is
on the CD added). MWL Easy Manager program is created only for the configurations of AMWL-DSP4
series.
Licensor is not responsible for any harm of the program operation or for the wrong use of the program.
MWL Easy Manager installation instruction
I. Program MWL Easy Manager requires the installation of Microsoft. NET Framework 3.5 Service Pack 1
for Windows NT, XP, 98 system ( for Windows Vista and windows 7 systems - there is not necessary).
Installation file is on CD added. Dotnetfx35.exe platform can be downloaded from the Microsoft
II. In the catalogue VCM Driver you can find drivers for use the USB port from the amplifierAMWL-DSP4
(CDM2.04.16.exe)- also need to be installed
III. After dotnet35fx.exe installation MWL Easy program can be installed
Installation file is in Rduch MWLEasyMgr 2.0 Install/Setup.exe
IV. After the program installation, it should work automatically.
V. After switching the amplifier on , program automatically detects port, where the device is installed.
Switching the amplifier on, is not necessary- parameters can be set in the program and than can be recorded in the
File first and aflter that the amplifier can be switched on and the data can be copied. To join the amplifier with the
computer, in the menu “ Comunication”, the order “join” should be chosen.

Setting of any priorities configuration: switching of any
switches in any channel's programmer causes the setting of
priority precedence of this channel over the previous
chosen channel. For example: switching in channel no 1
programmer, the switch no 4 down (ON) causes that
microphone no 1 can stop work of microphone no 4.
Lower configuration (picture no 3) shows the setting of the
priority for the microphone no 1 and no 2 (picture no 2).
The microphone no 1 has the priority over the
microphones from 2 to 8, and the microphone no 2 has the
priority over the microphones from 3 to 8, but is
subordinate to the microphone no 1. It means, that the
speeches of the microphones 3-8 can be stopped in any
time by the leader (1) or his deputy (2), but the speech of
the deputy (2) can be stopped only by the leader (1).

Lower configuration (pict. 4) shows the situation for three microphones, where each of them has the priority to two
ones left. In such a configuration, the priority goes to that microphone which is activated as the first one. So, when
he speech to tsomebody starts speaking to microphone no 2, the microphones no 1 and 3 are not active till the end
of the microphone no 2. Microphones no 1 and 3 behave analogically. Such a configuration is possible for all eight
microphones. Thanks to that, there is a situation, where only one microphone is always active and it makes
impossible for somebody else to interrupt, what is valuable for the order of the conference

8. Configuration and operation of the amplifier with additional power terminal
(AMWL-9DSP/400+100).
AMWL-DSP4 amplifiers have an additional 100W power terminal (option), where
the delay can be set.
100 W terminal can be switched on output DSP OUT 2 [28],
DSP OUT 3 [27] or DSP OUT 4 [19].
It is the switch inside the amplifier. Red arrow in the picture on the right, shows where it
is. The switch is described as the DSP outputs 1-4.
DSP OUT 1 [21],
The picture shows the typical use of the amplifier in that version
The main power terminal operates on one loudspeaker’s circuit
(red colour) but the other circuit (blue color)loudspeakers are
spaced. Then, it is possible to adjust demanding delay on the
DSP additional 100W power terminal, which operates on this
loudspeaker’s circuit. The additional 100W circuit can also be
activated via connector INFO OUT PRESET 2. This means
that for Preset 1, which is activated when for example in the
church are "little people" the additional 100W circuit is inactive
(break on connector INFO OUT PRESET 2). However, when
in the church are a "lot of people" for enabled Preset 2, the
additional speaker circiut 100V is activated.

9.AMWLC-9DSP4 amplifiers.
Each microphone channel of AMWLC-9DSP4 amplifiers is additionaly equipped with Compressor-Expander.
Practically, compressor-expander allows to reach the fixed volume level independently of the input signal level.
Compressor - expander parameters settings are fixed with switches and potentiometers that are located in the upper
cover of the amplifier.
