The new SX series
The new power engine of your sound system
Reliable even under hard touring and stage conditions the SX Series will drive your speaker with pure sound and less distortions. Very low noise temperature-controlled fans make this state of art amplifier series suitable for touring and fixed installations. Powerful up to 4 x 4600 Watt or 2 x 9000 @ 2 Ohm the SX series offer enough power even for huge subwoofer cluster. The digital controlled SMPS power supply offers stable working conditions and high efficiency even under weak or unstable mains supplies. Compact and with a depth of 402mm (486mm) the 1U high case weighs only 8,4 Kg (12Kg). All connectors are original Neutrik. Powercon for the mains connection, NL4 Speakon for the speaker outputs and XLR for the input signals. At the backside are dip switches to select the working mode and input sensitivity. The front panel is equipped with a power switch and multi-function LED rings.
