DESCRIPTION The PA-40M is a very compact amplifier specifically designed for small hotels and supermarkets, or mobile applications. Its small size and light weight make easy integration in little space. The 12V DC operation perfectly fits for portable use or installations where a direct AC power supply is unavailable. They are the ideal solutions for zoning, information points, ticketing counters, and vehicles using a rooftop speaker system. PA40M features an MP3 player with a UBS port, plus a siren triggered with a push button from the front panel. 2 Mic inputs are available with TRS 6.35mm jacks, plus 1 Aux stereo input on the rear panel with RCA connectors. All volume controls are on the front panel and include a simple EQ setting. The output section uses euro block connectors and features a 4Ω load.  FEATURES: Output: RMS 40W 2 Aux (RCA and 3.5mm jack) inputs Treble and bass adjustments Input volume adjustment and master output volume adjustment 2 Microphone (6.3mm) inputs MP3 module with USB interface Impedance output: 4Ω Power supply: DC 12V-15V 4A Master adjustments Siren switch  Under-table/Wall mount plate supplied SPECIFICATIONS Power supply: DC 12~15V, 4A Rated output power RMS: 40W Max Rated Power Consumption: 60W Rated impedance output: 4Ω Frequency response: 100Hz - 18K Hz (± 3dB) S/N Ratio > 65dBu THD 1%, -37dBu ± 2dB (MIC1~MIC2) Input Sensitivity: (1 kHz): -11dBu ± 2dB (AUX) Noise or Hum: 25mV MP3: USB Impedance output: 4Ω Dimension: (W x D x H)161 x 101 x 45 mm Weight:  0.73 kg PA40M Manual PDF file Weight: 2.00 kg Barcode Number: 4712646005337
