2. Using and general notices.
The modern amplifiers AMWL-DSPA (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-DSPA 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, an timer that switches presets liturgical
according to previously programmed date and time and an which eliminate sibilance during the speech.DE-ESSER

7. DE-ESSER
De-Esser is a device that removes / reduces sibilance (wheezing, whistling and rustling).
This device can be used in two modes, namely mode "full range FULL" or "division band split".
The FULL BAND mode (FULL) function is to reduce the entire signal when thedisturbing sound comes tilting the rest
of the band. In SPLIT mode you have to set the de-esser with the potentiometer (9). Set using the potentiometer (9) the
lowest frequency from which to uptake of unwanted sounds (sibilants). The setting range is 800 Hz - 8 kHz.
Sibilants appear typically between 3 - 4 kHz. Use the Potentiometer (7) to set the value of the suppression of the
captured unwanted frequencies (sibilance) from 0dB to -20dB. The LED indicator (8) shows how much the unwanted
frequency is suppressed at the moment.
BAND FUNKTION After pressing BAND the SPLIT mode is activated. If we set 3kHz the de-esser will damps
sibilance in the band of 3kHz to the upper threshold of 8kHz.
AIR FUNKTION
After pressing the AIR switch the higher frequencies will be protected.
Frequencies about 12kHz will be protected that the sound after “DE-ESSING” was still crystalline.

Channel programmers (1-8) factory settings: all switches of channels programmers in upper position (OFF).

Settings of any priorities' configurations: 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 the 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 participants 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).

Programmer nr 1 - default settings: all switches (1-8) in the
top position (OFF).
Switching any of the eight switches to the bottom position
(ON) turns off the automatic in each channel. This is useful if
you want to use one channel as a linear channel (music).
ATTENTION! If you want to use priorities, the channel

Programmer 2 - assigning the input channels 1-8 to the channel output mix 1 (MAINSUM 1).
Is assigned to input 1 (IN1) in the DSP.
Programmer 3 - assignment of input channels 1-8 to the mix output channel 2 (MAINSUM 2).
The assignment is to input 2 (IN2) in the DSP and output Jack (MIX OUT).
Programmer No. 4 - factory setting: switches 1 and 2 in position (OFF), switches 3 and 4 in position (ON).
Switch 1 - OUT2 PRE / POST GATE: upper position (OFF) POST GATE - all channels for MAINSUM-2 are
associated with the automation. Lower position (ON) PRE GATE - signals are assigned before automation.
Switch 2 - AUTO / MANUAL: upper position (AUTO) - function automatic operation of the mixer; lower position
(MANUAL) - a standard mixer (the automatic function off).
Switch 3 - ATTENUATION OFF: mute, inactive microphones, top position - muted; lower position - mute -15 dB.
Switch 4 - LAST MIC upper position (OFF) - last used microphone after speaking shuts down,
lower position (ON) - last used microphone after the speech remains active all the time.
WARNING! If you want to use a priority, this function must be disabled (upper position OFF).

8. Priorities settings

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

9. Configuration and operation of the amplifier with the additional power terminal
(AMWL-9DSPA/400+100).
Amplifier type AMWL-DSP 4A have optional an additional power amplifier
100W. .
The end of 100W can be switched on DSP output OUT 1 [33], DSP OUT 2 [33],
DSP OUT 3 [33] or DSP OUT 4 [33] (Inside the amplifier is a switch to do this).
The red arrow in the photo on the right shows the location. Switch has been
described by DSP output OUT 1-4 [33].
The picture shows the use of the amplifier in that version.
The main power terminal operates on one loudspeaker’s circuit
(red colour) and the other circuit loudspeakers are spaced. Then,
it is possible to adjust demanding delay on the additional 100W
power terminal, which operates on this loudspeaker’s circuit.

10.AMWLC-9DSP4A amplifiers.
Each microphone channel of AMWLC-9DSP4A amplifiers is additionaly equipped with Compresor-Expander.
Practically, compresor-expander allows to reach the fixed volume level independently of the input signal level.
Compresor - expander parameters settings are fixed with switches and potentiometers that are located in the upper
cover of the amplifier.
