1 INTRODUCTION
The LMS206 is a complete digital loudspeaker management system designed for the
touring or fixed sound installation markets. The absolute latest in available
technology is utilized with 64-bit floating point processors and high performance 24-
bit Analogue Converters. The high-bit DSP prevents noise and distortion induced by
truncation errors of the commonly used 24-bit fixed-point devices. A complete set of
parameters include I/O levels, 2 second-delay per channel, polarity, 10 bands of
parametric EQ per channel, multiple crossover selections, full function compressor
and peak limiter. Precise frequency control is achieved with its 1 Hz resolution.
Inputs and outputs can be routed in multiple configurations to meet any
requirements.
The LMS206 can be controlled or configured in real time on the front panel or with
the intuitive PC/Mac GUI accessed via the USB interface. Software upgrade for CPU
and DSP via PC keeps the device current with newly developed algorithms and
functions once available. Multiple setup storage and system security complete this
professional package.

3.2 The rear panel
A) Power switch - Controls power On/Off.
B) Main Power - Connects via a standard IEC socket. A compatible power cord is
supplied with the unit. The input voltage range is 85 to 240VAC, 50-60Hz.
C) XLR input and outputs - Separate 3-pin XLR connectors are provided for each
audio input and output. The device's output stage employs the balanced
impedance topology. All I/O connectors have pin 1 as ground (shield), pin 2 as +
and pin 3 as -.
4 QUICK INSTALLATION
4.1 Before you start
Before powering up the unit, make sure that the input and output XLR cables are in
good state and following the following pinning diagram: 1 for shield, 2 for live(+), 3
for return (-) as defined by the AES14 standard.
Do not connect the unit to your computer before installing the software and the USB
Driver. Please refer to installation instructions in this manual.
When connecting the LMS206 to the amplifiers, mute the DSP outputs (or turn down
the amplifier’s volume knobs) until you configure your processing. Loudspeakers
may be damaged due to a wrong setup. It is advisable to unmute first the high
frequency channels: in case they are connected to low frequency drivers by mistake,
they cannot be damaged. Otherwise, high frequency speakers may be damaged
because of trying to reproduce low frequencies.
4.2 Power Up
After powering up the unit, all LEDs will be lit for about six seconds, while the
following message is displayed on the LCD:
After that, the DSP unit displays its main screen:

Now the LMS206 unit is ready to operate. The screen shows the name of the unit
(above line) and the program name currently active (below line). The program
assigned is always the last program the user recalled or stored before powering
down the unit.
An admiration mark (!) beside the program name means that the program has been
modified but not stored. This symbol does not appear when the modified program is
the default preset.
4.3 1 Control Software
The LMS206 units can be controlled via a Computer Software which provides a
Graphic User Interface (GUI) application - DSPLink. DSPLink allows the user to
control the DSP unit from a computer via the USB communication link. For the USB
connection, a driver must be installed (included with the DSPLink installation
package).
The GUI application makes it much easier to control and monitor the device, allowing
the user to get the whole picture on one screen. Programs can be recalled and
stored from/to Computer’s hard drive, thus expanding the storage to become virtually
limitless. See Section 6 of this manual for instructions to operate the software.
DSPLink is available for PC and Mac. Check Amate Audio’s website for a latest
version download (www.amateaudio.com).
Installation for PC-Windows:
Double click the installation file, depending whether you have a 32 or a 64-bit
system:
Amate_Audio_DSPLink_32_bit_v_10_X_X_BuildNr.msi
Amate_Audio_DSPLink_64_bit_v_10_X_X_BuildNr.msi
Follow the on-screen instructions. You may be prompted to install the Microsoft
Visual Runtime libraries before finishing the installation. Click the checkbox to
proceed with this action.
Installation for Mac:
First unzip the provided installation file:
Amate_Audio_DSPLink_v_10_X_X_BuildNr.mpkg.zip
Then select the .mkpg file with CONTROL+Click and select “Open”. Then follow the
on-screen instructions.
4.4 Connecting the device to a computer
WARNING: Always install the software package DSPLink before connecting your
unit to the computer. See previous section for details.
After installing DSPLink, please use the provided USB cable to connect the unit to
your computer. The first time you connect a device, the system will ask you to look

for the driver. Choose the option “do not look for updates and to automatically select
the best driver”.
Run DSPLink and the unit will be automatically detected. Click on the arrow next to
the detected unit to open the window for parameter edition.
4.5 System Optimization
In order to have a proper start of your system and an optimized configuration, follow
these steps by the first configuration:
1. Play a signal at the nominal level from your mixing desk, and set the input
gain of your processor to 0dB (Default Preset setting)
2. Set the crossovers that you want to use, while keeping the output gains also
at 0dB.
3. With DISCONNECTED loudspeakers, turn up the volume of the power
amplifiers entirely clockwise (full volume).
4. Reduce the output gain and / or the output limiter setting to get the desired
gain, so that the amplifier is just clipping and the built-in limiters of your
processor are just limiting (Orange led blinking at the output channels).
5. Turn down the volume of the power amplifiers, connect your speakers, and
slowly increase the volume while checking the sound.
6. Check if the loudspeakers are reproducing distortion-free sound, and the
limiter LEDs are flashing or off, but not continuously on. If they are
continuously on, reduce the output gain of your processor.
7. If you cannot reach enough signal level, increase the processor's input gain or
turn up the level from your mixing desk

4.6 Diagram of a typical setup
With illustrative purposes, a diagram of a LMS206 working as audio manager in a
typical setup is shown above. The audio processor is used for splitting the stereo
signal coming from a mixer in two zones for different public. In fixed setups, is
common that these two zones have different acoustical properties so different audio
gear is expected. Due the previous considerations, a different signal processing for
each zone is expected.

In the case of set-ups without subwoofer units, the presets configure the passive
loudspeakers as full-range loudspeakers so they will reproduce all the frequency
range.
For the case of set-ups with subwoofers, the output channels from 1 to 4
(Corresponding to the “tops”) are configured with a high pass filter, and the channels
5 to 6 (Corresponding to the “subs”) are configured with a low pass filter and a boost
of 3 dB in the tuning frequency. In this way we obtain a set-up with a balanced
frequency response.
These presets are read-only, in consequence they can’t be overwritten, edited nor
deleted. If you want to edit a preset, before is necessary to copy it to another free
memory available.
The presets don’t include the proper limiter threshold, since it depends in the number
of cabinets and amplifier type that are part of the sound system. For computing the
proper limiter threshold, it is highly recommended to use the tool we have available
in the following link: amateaudio.com/en/LimCal
