    McIntosh MI1250

    This 12-channel amplifier, capable of delivering 50 watts per channel, has a pleasant appearance and can be mounted in a rack. The integrated cooling system eliminates the need to install noisy fans. The back panel has volume controls for each channel, four digital inputs, two optical and two coaxial. There are BUS connectors for connecting multiple amplifiers.

  • MI128

    Power amplifiers stereo

    McIntosh MI128

    The power of the device is 120 watts per channel, which allows for effective amplification for voicing an area of more than 100 square meters. With a resistance of 4 ohms, the power increases to 150 watts. The high efficiency of the amplifier made it possible to eliminate noisy active cooling, traditional radiators are enough to maintain a normal operating temperature even with many hours of operation.

  • MI347

    Power amplifiers stereo

    McIntosh MI347

    The McIntosh MI347 amplifier is equipped with a range of proprietary protection technologies, including an anti-overload Power Guard that protects speakers and a Sentry Monitor that protects against short circuits. The Power Control system allows you to synchronize the switching on and off of the amplifier and other McIntosh components, such as the MX100 processor. In addition, the McIntosh MI347 switch-on and off system is implemented based on the presence of a useful signal at one of the inputs.

    McIntosh MI254

    The McIntosh MI254 4-channel digital amplifier is a versatile multi-channel amplifier, ideal for use in a home theater or stereo sound reproduction system. It outputs 250 watts to 8 ohm speakers or 300 watts to 4 ohm speakers thanks to its sophisticated digital feedback switching amplifiers. These amplifiers are connected to extremely reliable power supplies that deliver performance levels rarely achieved in distributed audio.

  • MI502

    Power amplifiers stereo

    McIntosh MI502

    The McIntosh MI502 dual-channel amplifier offers 500 watts per channel when operating on a load rated at 8 ohms or 800 watts at 4 ohms. The manufacturer claims that the new product uses innovative closed-loop digital switching technology and powerful power supplies that provide such outstanding performance combined with McIntosh's signature sound signature.
