S5 Stereo Power Amplifier /M8 Monoblock Power Amplifier
A Word About Watts
The S5 power output is rated as 500 watts for each channel, when both
channels are operating together at full power at across a full 20 Hz to 20K
Hz. And the M8 power output is rated as 1080 watts in 8 ohms load when it
is operating at full power. Michi has chosen to specify the power output in this
way because, in our experience, it gives the most true value of the receiver or
amplifier’s power capability.
When comparing performance and specifications for different products, you
should be aware that power output is often specified in other ways so you
may not be comparing like with like. For example, the power output may be
quoted with only one channel operating at a much higher distortion output
or a single, ideal frequency, giving a higher maximum power output figure.
A loudspeaker’s impedance rating indicates the electrical resistance or load it
offers when connected to the amplifier, usually 8 ohms or 4 ohms. The lower
the impedance, the more power the speaker will need. In effect, a 4 ohm
speaker will require twice as much power as an 8 ohm speaker.
However, Michi amplifiers are designed to work into any speaker impedance
between 8 and 4 ohms, and with all the channels working up to their full power.
Because Michi designs are optimized for use with all channels operating
together, Michi is able to specify the true power output for both channels.
This architecture, design and performance rating is sure to please both the
speakers and audience when enjoying music of any genre or listening level.
Getting Started
Thank you for purchasing the Michi S5 Stereo Power Amplifier or Michi M8
Monoblock Power Amplifier. When used in a high-quality music audio system,
your Michi product will provide years of musical enjoyment.
The S5 and M8 are high-power professional amplifiers, providing the highest
level of audio performance. A massive power supply, premium components,
and Michi’s design architecture ensure superb sound quality. High current
capability of this power supply allows the S5 and M8 to drive the most
demanding loudspeakers.
Be aware that the S5 and M8 are capable of high power levels, in excess of 500
watts and 1080 watts respectively per channel. Make sure that your speakers
can handle the power of the amplifier. If in doubt about your speakers, ask
your local Michi audio dealer for advice.
This amplifier is straightforward in its installation and operation. If you have
experience with other power amplifiers, you shouldn’t find anything perplexing.
Simply plug in the associated components and enjoy.
A Few Precautions
WARNING: To avoid potential damage to your system, turn off ALL
the components in the system when connecting or disconnecting the
loudspeakers or any associated components. Do not turn the system
components back on until you are sure all the connections are correct
and secure. Pay particular attention to the speaker wires. There must
be no loose strands that could contact the other speaker wires, or the
chassis of the amplifier.
