2 Foreword

2Foreword
The four-channel S-Series system amplifiers cover a wide range of applications with a total output
of 2.5 to 20 kilowatts. They are able to drive high and low impedances and are therefore suitable
for both live applications and fixed installations.
The amplifiers are equipped with a high-quality 64-bit double-precision 96kHz FIR DSP and a
large, capacitive IPS touch display. The DSP contains a very extensive preset library for
SEEBURG loudspeakers. The user can also create their own presets for third-party products.
The S-Series can be fully operated and monitored remotely via Ethernet. Thanks to the integrated
network switch, the network connection can be passed on directly to the next device (daisy chain).
Analogue and digital (AES3) signals can be fed in via the XLR inputs. Optionally, audio over
Ethernet (AoE) signals can be processed via an AES67 interface (Dante™ compatible).
The wide-range switching power supplies allow operation on mains voltages from 90 to 265 volts.
They have an active power factor correction (PFC) and thus relieve the mains supply considerably.
Thanks to the latest generation of Class D topology, the power amplifiers achieve very high levels
of efficiency regardless of the load. They generate very little waste heat, which is dissipated to the
rear by a temperature-controlled, quiet fan. The already low idle power consumption can be re-
duced to below 5W by a remotely switchable standby mode.
The amplifier channels can drive low-impedance loads down to 2 ohms, as well as high-impedance
loads in 100V/70V/50V/35V lines. The advanced power management PCM™ provides the highest
possible output power on the individual channels until the capacity of the power supply is ex-
hausted.

3Safety Instructions & Installation
ATTENTION!
The lightning symbol indicates the presence of possibly uninsulated,
dangerous voltages!
Read this manual before using the device!
When the appliance is installed, the plug inserted into the socket
outlet must be easily accessible.
The device must be earthed (via the mains plug).
Observe the professional association regulation BGV A2 –"Electrical
systems and equipment" or the equivalent of this regulation valid in
your country.
If necessary, observe any deviating regulations when using the de-
vice abroad.
The amplifier may only be connected to the loudspeakers by a spe-
cialist.
INSTALLATION NOTES
Note that the airflow to cool these devices is front-to-back.
Make sure that there are no objects on the front and back of the de-
vice that would impede the airflow and thus the correct functioning of
the cooling system.
Objects to the right and left of the device should be at least 2 centi-
meters away.

4.2 Rear Panel
(1) Signal Input:
Neutrik® XLR sockets for analogue or digital (AES3) signals. Sockets 1 and 3 are used for
the two-channel AES3 signals.
(2) Signal Link:
Parallel XLR outputs for daisy-chaining the signal to other amplifiers.
(3) Loudspeaker Connectors:
Neutrik® SpeakOn™ receptacles for connecting the loudspeakers.
(4) Ethernet Ports:
2x RJ45-compatible Neutrik® EtherCon™ sockets for connecting to a network. With switch
for direct connection (daisy-chaining) to other amplifiers.
(5) Mains Connection:
Neutrik® PowerCon™ socket for connection of a 3-wire power cable according to local
regulations. Socket can be switched under load and has the function of a mains switch.
For fractions of a second, the amplifiers can draw peak currents far in
excess of what is listed under “Rated Current Consumption” in the
data table. We recommend operating the amplifiers on circuit break-
ers with C characteristics.

5.1 Connections
Connect the amplifier to a properly grounded AC 90-265V AC outlet.
The audio input signal can be either balanced or unbalanced.
Balanced signal: pin 1 ground, pin 2 positive signal (hot), pin 3 negative signal (cold).
Unbalanced signal: pin 1 ground, pin 2 signal, pin 3 ground.
ATTENTION: If you connect an unbalanced signal and pin 3 is not connected to the ground, this
creates a loss of 6dB signal level at the output!
5.2 Start-up
As soon as the mains supply is restored, the amplifier restores the last operating state. If the power
amplifier was previously in standby mode, this is restored - if the power amplifier was previously in
operation, it switches on again and uses the last settings made. This includes all loaded speaker
presets, level, mute, delay, EQ settings etc.
If the amplifier is in the standby state, it is switched on by pressing the operating mode button for at
least one second. Booting up takes only a few seconds and the last set values are restored.
If the amplifier is in operation, pressing the operating mode button for at least one second puts it
into standby mode. It can then only be addressed via Ethernet.

5.3 Signal Flow Basics
The figure shows a configuration example of the amplifiers and in it the basic structure of the signal
flow from left (input) to right (output).
The physical hardware inputs are assigned to the sources, denoted by the lowercase letters a, b, c
and d. You can choose between analogue and digital inputs. For each input type, the number of
the hardware input is selected. For the XLR inputs, the number corresponds to the labeling on the
device: a1…a4 for analog or d1…d4 for AES3. Next, a source is assigned to the input path, denot-
ed by the capital letters A, B, Cand D. You can choose from the four individual sources as well as
the combinations a+b and c+d.
Each input path has a User EQ section. This provides six multimode filters, a high-pass filter, input
delay, input gain, polarity reversal and muting. The user can save all the settings made here as
presets on the device via the PC software for later use.
The Groups section that follows houses all the EQs, gains and delays added via the grouping
function in the PC software.
Finally, a speaker system is assigned to the path. The System preset contains all the basic cross-
over and protection functions, while the Mode EQ contains the settings specific to the respective
operating mode. In the case of multi-way speakers, the signal is output to the adjacent outputs.

5.4 Using the User Interface
The power amplifiers are operated via a touch-sensitive color display and an endless encoder with
a push button function.
By touching the individual areas and "buttons" on the display, you can navigate directly to the re-
spective function. The selection of a function or an input field is highlighted by a blue border around
it.
If you touch a "mute button" it is selected and also switched simultaneously.
The encoder has two essential functions: navigation and value input. In the initial state it is in navi-
gation mode. As the encoder is turned, each function and “button” on the display is cycled through
in sequence, each highlighted by a blue border.
If the encoder is pressed (keyed), it switches to input mode (then the respective field is framed in
red) - or activates the function of the button (e.g. mute). If an input field is selected, the value of the
input field can be changed by turning the encoder. If a preset list is selected, it can be scrolled up
and down. Pressing the encoder again then loads the selected preset.
If no values are entered with the encoder for a while, it automatically switches back to navigation
mode.

x.x1) contain phase linearization and time alignments. Version numbers ending in a 0 (e.g.
x.x0) do not include these features and are therefore compatible with HDLM8 and self-
powered speaker systems. The latest versions can be found in the download area of the
SEEBURG website.
