Foreword
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.
