Power Amplifier Module - 1200W

 PA12CC.pdf Manual

PA12CC is an extremely powerful bipolar amplifier of classical design working in class AB with moderate power consumption. PA12CC is suitable for low impedance loads like ribbon tweeters without transformer, multiple active bass driver systems or high power bridged configuration.

PA12CC consists of a differential cascode coupled input stage controlled by a current generator. The input stage is totally discreet to optimize for linearity and bandwidth. The voltage gain stage is also cascode coupled, which is differentially symmetric in class A, to achieve low distortion at high frequencies. The output stage is of high current gain being an easy load to the voltage gain stage. The output stage consists of 24 pieces totally complimentary high speed high power bipolar transistors.

PA12CC are decoupled at positive and negative supply with 15uF polypropylene capacitors.

PA12CC has short circuit protection, thermal protection and rail fuses to prevent output device break down.

PA12CC features sonic excellence, constant low output impedance, low noise, low distortion and high reliability.

The maximum power output depends on voltage supply, heat sink and load conditions. Recommendations: Voltage supply of + / - 95V, heat sink less than 0,2 K / W and minimum load of 1,5Ω.
