SMA-1000 Amplifier 2x500W/4 ohm

Stereo PA amplifier with integrated limiter and SMPS

• Low weight and height due to integrated switch-mode power supply
• Temperature-controlled fan, particularly quiet during operation
• Limiter and speaker switch-on delay
• Peak filter at 80 Hz with 6 dB level increase
• 3 operating modes can be selected (stereo, parallel or bridged)
• Selectable input sensitivity
• 2 level controls
• 3 LEDs for each channel for activated protective circuit (protect) overload (clip) and signal
• 2 LEDs for parallel and bridge operation
• Complete protection set against short-circuit, overheat, DC voltage and VHF signals
• Electronically balanced inputs via XLR mounting jacks, with feed-through output (stereo RCA/6.3 mm jack)
• Speaker outputs via lockable Speaker plugs
• Class AB circuitry
