A Word About Watts
The X3 power output is rated as 350 watts for each channel when both channels
are operating together at full power at across a full 20 Hz to 20K Hz. 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 Stereo Integrated Amplifier. When used
in a high-quality music audio system, your Michi product will provide years
of musical enjoyment.
The X3 are a full featured, high performance component. All aspects of the
design have been optimized to retain the full dynamic range and subtle nuances
of your music. Both X3 have a highly regulated power supply incorporating a
Michi custom-designed toroidal power transformer and custom-made slit foil
capacitors. This low impedance power supply has ample power reserves, which
enables the X3 to easily reproduce the most demanding audio signals. This
type of design is more expensive to manufacture, but it is better for the music.
The printed circuit boards (PCB) are designed with Symmetrical Circuit
Traces. This insures that the precise timing of the music is maintained and
faithfully recreated. The X3 circuitry use metal film resistors and polystyrene
or polypropylene capacitors in important signal paths. All aspects of this
design have been examined to ensure the most faithful music reproduction.
The main functions of the X3 are easy to install and use. If you have experience
with other stereo systems, 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.
