The 300AS1 combines an efficient forward type power supply with a 1x 300 W high quality class D amplifier. It includes a DC hanger bus for powering up to three 300A1 hanger amplifiers. On its own it is therefore perfect for single channel applications such as subwoofers, bass and guitar amplifiers.

  • Output power: 300W (4Ω), 150W (8Ω)

  • Distorsion THD + N (1W / 1kHz) = 0.006  %

  • Minimum load impedance = 2.5 Ω

  • Dynamic range = 113db

  • Frequency Response  3hz-70Khz   

  • Voltage Gain 28.15db

  • Input Impedance 47Kohm 

  • Idle noise output (A) = 75mV

  • Maximum output current 20A

Combined with 300A1 hanger amplifiers, it can be used for 2- and 3-way PA speakers, studio monitors, hifi and home automation amplifiers.


The 300A1 is the amplifier section of the 300AS1. It is a great sounding 1x 300 W class D amplifier which can be powered from the DC hanger bus of the 300AS1, the 700AS1/2 and the 1200AS1/2.


• Subwoofers

• High-end stereo and multi-channel amplifiers

• Active 2 and 3  way speakers

• Bass amplifiers
