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.

3 Safety Instructions & Installation

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.

4.1 Front Panel

(1) Illuminated operating mode button:

Lights up as soon as mains voltage is present. Red: Device in standby, can be addressed

via Ethernet. Green: device in operation.

To switch the operating mode, hold down the button for one second.

(2) Touch Screen:

Display information and enter settings. See the Operation section of this manual.

(3) Push Encoder:

Navigation across the display areas, changing and entering settings.

(4) USB Socket:

For firmware updates and device control without Ethernet.

4 Device Overview

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.

5Operation

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 Operation

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.
