Product description:

MA Series 4CH power amplifier

Features
 MA series use a very mature 2 H class switching circuit topology
 XLR input connectors and link connectors
 SpeakON NL4 output connectors
 Input sensitivity selector on rear panel (32dB/1v/0.775v)
 Link mode selector on rear panel(stereo / bridging /parallel)
 Channel independent alarm indicators(temperature/protection/clip)on front panel
Superior electronic components
 As the CS audio marketing king, MA series only use the components from the market which is considered most durable and superior.
 Adopt imported ONSEMICONDUCTOR transistors 0302/0281, professional customized audio button-type wires, which can prevent the transportation loss.
 Long-lived capacitors features high heat proof, high frequency and low resistance, pursue quality regardless of costs.
 MA series amplifiers adopt high-quality pure copper transformer, electromagnetic loss and temperature rise is very low by using imported silicon steel sheet core.
Tone features
 The high frequency clear, warm tone
 Mid frequency warm and full, voice full of charm
 The low frequency bass heavy and powerful, moderate sense of forcefulness
Multiple protections
 Short circuit protection
 Over load protection
 DC protection
 Output of automatic limit
