Safety instructions
When using this electronic device, basic precautions
should always be taken, including the following:
-
Read all instructions before using the product.
-
Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a

fall into liquids and liquids would not be spilled on the device. -
Use this device when you are sure that it has a stable base and it is fixed securely.
-
This product may be capable of producing sound levels that could cause permanent
hearing loss. Do not operate for a long period of time at a high volume level or at a
level that is uncomfortable. If you experience any hearing loss or ringing in the ears,
you should consult with otorhinolaryngologist. -
The product should be located away from heat sources such as radiators, heat vents,
or other devices that produce heat. -
Note for power connections: for pluggable equipment, the socket-outlet shall be
installed near the equipment and shall be easily accessible. -
The power supply should be undamaged and never share an outlet or extension
cord with other devices. Never leave device plugged into the outlet when it is not
being used for a long period of time. -
Power disconnection: when the power cord connected to the power grid is
connected to the machine, the standby power is turned ON. When the power switch
is turned ON, the main power is turned ON. The only operation to disconnect the
power supply from the grid, unplug the power cord. -
Protective Grounding – An apparatus with class I construction shall be connected to
a power outlet socket with a protective grounding connection.
Protective Earthing – An apparatus with class I construction shall be connected to a
mains socket outlet with a protective earthing connection. -
The lightning flash with an arrowhead symbol, with an equilateral triangle,
is intended to alert the user to the presence of uninsulated dangerous
voltage’ within the products enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons. -
The exclamation mark within an equilateral triangle is intended to alert the
user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance. -
There are some areas with high voltage inside, to reduce the risk of electric shock
do not remove cover of the device or power supply.
The cover should be removed by the qualified personnel only. -
The product should be serviced by qualified service personnel if:
– The power supply or the plug has been damaged.
– Objects have fallen into or liquid has been spilled on the product.
– The product has been exposed to rain.
– The product has been dropped or the enclosure damaged.

with the power switch on the back panel.
USB TYPE-B CABLE SOCKET
Connect your device with PC using type-B USB cable.
INPUT & OUTPUT CONNECTORS
Balanced Phoenix connectors for sound signal inputs and outputs.
Use balanced sound cables.
MAINS POWER CONNECTOR

Software interface
Connecting to device & navigating windows
SOFTWARE DOWNLOAD
Visit www.amcpro.eu software & documents section to download the latest
software for your device.
SYSTEM REQUIREMENTS
The software works with Windows XP / WIN7 / WIN8 / WIN10 x64 or x32
operating system, and can run directly from PC without installation.
CONNECTING TO DEVICE
Connect device to PC using USB type-B cable. Run the DSP46 software on the
computer. The device will automatically connect to the computer within 3-5
seconds. The green “connected” indicator (1) will be displayed at the top of
the
window to indicate ongoing connection.
SWITCHING WINDOWS
The software has four main tabs for audio and device settings. Click on the
tabs “Audio Setting” (2), X-over (3), Router (4) or “System Setting” (5) to
switch
window.
NAVIGATING SETTINGS
Click on the parameter to enter its setting window. The selected parameter
will
be highlited with different colour.
The user interface follows signal patch starting with settings for each of 4
inputs, visually displayed input/output matrix (called Router) and finishes
with 6
outputs and their dedicated settings.
Software interface
Audio Settings
NOISE GATE (6)
Set the threshold level, attack and
release time for channel input noise gate.
INPUT GAIN (7)
Set the signal input gain using the slider,
or by entering specific value in dB.
Here the channel can be muted or
phase-inverted.
INPUT EQUALIZER (PEQ) (8)
Input channels have separate 10-band equalizers. Each band can be set to act
as parametric (PEQ), low or high shelf (LSLV / HSLV).
Click and hold left button on the highlited circle with an EQ band number
and drag it to set the frequency and gain. Each parameter can also be set by
entering specific values in the chart. Each band can be individually bypassed.
BYPASS button mutes and unmutes all EQ bands at once.
RESET button restores all EQ settings to the default values.
COPY/PASTE buttons allow copying EQ settings from one input channel to
another.
Note: it is not possible to copy EQ settings from inputs to outputs.
Software interface
Audio Settings
INPUT DELAY (9)
Set a delay for each input channel. Delay
range is 0.021-20 ms., value can also be
entered in milliseconds, in centimetres
or inches.
AUDIO ROUTER (4 & 10)
DSP4X6 provides flexible input-output matrix for signal routing. Each input
channel can be assigned to any outputs, also each output channel can mix
multiple inputs. Note: by default setting DSP4X6 inputs are routed as in the
picture below.
CROSSOVER (11)
DSP4X6 can function as a crossover, with separate settings for each output.
Set the high-pass and low-pass filters for each output by entering filter
frequency, selecting roll-off curve shape and intensity from the list.
OUTPUT DELAY (13)
Set a delay for each output channel. Delay
range is 0.021-20 ms., value can also be
entered in milliseconds, in centimetres
or inches.

Audio Settings
OUTPUT EQUALIZER (12)
Output channels have separate 10-band equalizers. Each band can be set to act
as parametric (PEQ), low or high shelf (LSLV / HSLV). Crossover settings are
also
displayed and can be changed in this window.
Click and hold left button on the highlited circle with an EQ band number
and drag it to set the frequency and gain. Each parameter can also be set by
entering specific values in the chart. Each band can be individually bypassed.
BYPASS button mutes and unmutes all EQ bands at once.
RESET button restores all EQ settings to the default values.
COPY/PASTE buttons allow copying EQ settings from one input channel to
another. Note: it is not possible to copy EQ settings from outputs to inputs.

PRESETS FOR AMC RF PROFESSIONAL LOUDSPEAKERS
By default DSP4X6 comes with pre-defined presets for various setups for
AMC RF series professional loudspeakers.
Presets adjust PEQ and crossover settings for AMC loudspeakers RF 10, RF 6,
and a subwoofer RFS 12. A “Flat” preset has a PEQ correction to flatten the
loudspeaker audio frequency curve, while a “Boost” preset has a lift in a
lowfrequency
range. All presets are for stereo setup and have the following input output
configurations:
