McIntosh

The McIntosh MC462 uses the proprietary Quad Balanced circuit and Autoformer technology, its output power of 2 x 450 watts is absolutely load tolerant (the indicators do not change on any speakers with a resistance from 2 to 8 ohms). The dynamic range margin has been increased (the filter bandwidth has increased by one and a half times), the signal-to-noise ratio reaches 122 dB.

Like the MC302, which the MC312 replaced, it is a transistor stereo amplifier with a power of 300 watts per channel, which is an excellent choice for powering almost any speaker system. Thanks to the unique Autoformer technology, all 300 watts can be applied to almost any speaker, no matter what impedance they have 2, 4 or 8 ohms.

The McIntosh MC152 is a 150—watt amplifier that can work with speakers with 2, 4, and 8-inch integrated scanners. The device implements the Autoformer system, which ensures that each speaker receives full power regardless of resistance.

The MC2152 70th Anniversary Vacuum Tube Amplifier is a 150 Watt per channel stereo amplifier and features a striking new design to celebrate seven decades of handcrafting some of the best home audio equipment the world has ever heard. While its design is new, the MC2152 incorporates the lessons we’ve learned and the techniques we’ve invented in 70 years of audio engineering.

Technically, the device is based on the MC2152 anniversary model. This means using 12AX7A and 12AT7 lamps in the input and driver stages, as well as eight KT88 lamps at the output, four per channel. The novelty's power is 150 Watts per channel, and separate 2.4 and 8 ohm terminals are provided for connecting speakers with different nominal resistances.

The MC275 consists of two separate 75W power amplifier channels for 4, 8, or 16 ohm speakers. Two channels can be combined into one 150 watt channel for 2, 4, 8 ohm speakers.

The McIntosh MC303 audio amplifier has three channels and provides a 300 watt signal output for each channel. The device produces high-quality sound with a low level of interference and low noise, regardless of the overall actual volume. The device differs from other models by the presence of the Sentry Monitor function, which protects it from a short circuit. The meters constantly monitor the peak power level, and when it is exceeded, the device automatically turns off.

The McIntosh MC255 AV amplifier has five channels. The huge 15’ TripleView display with blue backlight looks very interesting, the circuitry has improved again. The best filters were used, the dynamic range was increased by 3.5 dB; the input power is 5 x 200 watts per 8 ohm load.

The device can develop a power of up to 250 watts for each of the seven channels, while the proprietary Dynamic Power Management scheme can redistribute power between channels depending on needs. Monogrammed Heatsinks shaped radiators allow you to do without noisy cooling fans.

The MC8207 is a 7-channel amplifier that was designed to work as part of a home theater. You can use all seven channels to sound the system in a large room, or five for movies and two for a pair of speakers in an adjacent room. The amplifier outputs 200 watts per channel for speakers with an impedance of 4 or 8 ohms.

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.

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.

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.

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.

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.
