The MA-500 is a 2 channel stereo power amplifier with the use of 32 carefully selected and matched powerful MOSFET transistors (8 pairs per channel,
16 pairs total). With a rated
output power of 450 watts per channel at 8 ohms (900 watts per channel at 4 ohms), the MA-500 is capable of driving any loudspeakers
even with low efficiency and low impedance.
Each of the MA-500 power amplifier is handcrafted with the use of highest quality parts and components. The audio grade toroidal
transformer is custom wound according to our specifications. Even the heavy-duty special designed heat sinks are custom made in
order to meet our standards.
Advance and sophisticated Class AB design with high output performance.
32 carefully selected and matched MOSFET output transistors of highest quality.
Current mirror input for more stable output throughout entire dynamic range
Custom wound audio grade toroidal transformer with separate windings for
left and right channel.
Custom made heavy-duty heat sinks with special thick rib design ensure a
lower operating temperature.
Sophisticated protective circuit ensures highest operational safety for the
amplifier and the connected loudspeakers.
Integrated power curcuit with time-delay relay to eliminate turn-on thump.
Advance layout and wiring techniques guarantee a hum free operation.
Switchable balanced (XLR) and single-ended (RCA) inputs.
Full metal housing for optimum shielding.
Handcrafted in California, USA.
