Introduction:
  C-Mark Q series high efficiency Class D power amplifier has perfect protection function, powerful output power with excellent loading capability, and both constant voltage and impedance output modes. It can be applied for venues such as theatre, multi-purpose hall, big stadium, theme park, outdoor performance, sport fields. Wide power supply voltage of AC100-240V 50/60Hz suitable for worldwide mains.

 Features:
1. characterized by fabulous tone, high efficiency, light weight, stable and reliable working performance
2. with perfect protection function(short-circuit protection, over-current protection, over temperature protection, over-voltage protection, insufficient voltage protection, temperature limiter, input signal limiter)and nice character of electromagnetic compatibility
3. both constant voltage and impedance output modes are available. Output impedance is 4-16Ω, output voltage is 70V/100V or 140V/200V(bridged mode)
4. built in two big power toroidal transformers with 50 Hz-18kHz frequency response to ensure complete output isolation and reliability
5. LF filter is built in with switchable frequency between 45Hz and 75Hz to prevent the transformer from over-load in constant voltage output
