12 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
isoperatingat fullpower.Michi haschosen to specifythe poweroutput in this
way because, in our experience, it gives the most true value of the receiver or
amplifier’s power capability.
Whencomparingperformance and specificationsfordifferentproducts,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.
Aloudspeaker’s impedanceratingindicatesthe electrical resistance or loadit
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
between8and4 ohms,and withall thechannels workingup totheir fullpower.
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.

Placement
The S5 and M8 generate heat as part of its normal operation. The heatsinks
and ventilation openings in the amplifier are designed to dissipate this heat.
There should be 50 cm (20 inches) of clearance around the chassis and
reasonable airflow through the installation location to prevent the amplifier
from overheating.

AC Power and Control
AC Power Input -
Youramplifier is configuredatthe factoryforthe properAC linevoltage in the
country where you purchased it (either 120 volts AC or 230 volts AC with a
line frequency of either 50 Hz or 60 Hz). The AC line configuration is noted
on a decal on the back panel.
NOTE: Should you move your amplifier to another country, it is possible
to reconfigure your amplifier for use on a different line voltage. Do not
attempt to perform this conversion yourself. Opening the enclosure of
the amplifier exposes you to dangerous voltages. Consult a qualified
service person or the Michi factory service department for information.
NOTE: Some products are intended for sale in more than one country
and as such are supplied with more than one AC cord. Please only use
the one appropriate for your country/region.
Becauseofits relativelyhigh powerrating,the amplifiercan draw considerable
current.Therefore,it shouldbepluggeddirectlyintoapolarized walloutletusing
the supplied cable or other high current compatible cable as recommended
by your authorized Michi dealer. Do not use an extension cord.
If you are going to be away from home for an extended period of time such as
amonth-long vacation,it isa sensible precautiontounplug youramplifier(as
well as other audio and video components) while you are away.

Master Power Switch -
The large rocker switch on the rear panel is a master power switch. When it is
in the OFF position, power to the unit is completely off. When it is in the ON
position,the frontpanelPower2buttonandremotecontrolPowerAbutton
can be used to activate the unit or put it into standby mode.
12V TRIGGER Connection 9
See Figures 5-1/5-2
The jack labeled IN is for connecting the 3.5 mm Plug/Cable carrying a +12
volt trigger signal to turn the amplifier on and off. This input accepts any
control signal (AC or DC) ranging from 3 volts to 30 volts.
Thejack labeled OUT isforconnecting another 3.5 mmplug/cabletoprovide
a 12V trigger signal to other components. The 12V output signal is available
whenever a +12 volt trigger signal is applied to the IN connector.
Protection Circuitry 2
The amplifier features thermal and over-current protection circuits that
protect against potential damage in the event of extreme or faulty operating
conditions. Unlike many designs, these protection circuits are independent
of the audio signal and have no impact on sonic performance. Instead, the
protection circuits monitors the temperature of the output devices and the
currenttheyarehandling andshuts downthe amplifierif operatingconditions
exceed safe limits.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplifier will stop playing and the Power
LED on the front panel will be red.
If this happens, turn the amplifier off, let it cool down for several minutes, and
attempttoidentifyand correctthe problem.When youturntheamplifier back
on, the protection circuit will automatically reset and the Power LED should
be white, indicating that the amplifier is operating normally.
Inmostcases,theprotectioncircuitryactivatesbecauseofafaultconditionsuch

condition. In very rare cases, highly reactive or extremely low impedance
speaker loads could cause the protection circuit to engage.
If the protection circuitry triggers repeatedly and you are unable to isolate
and correct the faulty condition, contact your authorized Michi dealer for
assistance in troubleshooting.

NOTE: You should choose only one method of analog connection from
a source component to the amplifier. Do not connect both the RCA and
XLR outputs of a source component to the amplifier at the same time.
Speaker Outputs
See Figures 3-1/3-2
Speaker Selection
We recommend using loudspeakers with a nominal impedance of 4 ohms or
higher with the amplifier. The dual output binding posts are ideal for bi-wire
installations allowing 2 pairs of wires to drive the HF and LF speakers each
with individual wires from the left or right channel of the amplifier. Speaker
impedance ratings are less than precise so use care when selecting the
loudspeakers to attach to the amplifier. In practice, very few loudspeakers
will present any problems for the amplifier. See your authorized Michi dealer
if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the amplifier to the
speakers. The size and quality of the wire can have an audible effect on the
performance of the system. Standard speaker wire will work, but can result in
loweroutput ordiminished bass response,particularly overlonger distances.
Ingeneral,heavierwirewill improvethesound. Forbestperformance,youmay
want to consider special high-quality speaker cables. Your authorized Michi
dealer can help in the selection of cables for your system.
Polarity and Phasing
Thepolarity – the positive/negativeorientationof the connections– forevery
speaker and amplifier connection must be consistent so all the speakers will
be in phase. If the polarity of one connection is reversed, bass output will be
veryweakandstereoimagingdegraded. Allwire ismarkedso youcanidentify
the two conductors. There may be ribs or a stripe on the insulation of one
conductor.The wiremayhaveclear insulationwith different colorconductors
(copperand silver).Theremaybepolarity indicationsprintedonthe insulation.
Identify the positive and negative conductors and be consistent with every
speaker and amplifier connection.
Speaker Connections 0=
NOTE: The following text describes both binding post and plug-in
connections. DO NOT use both connection methods in combination to
connect multiple speakers.
Turnoff allthe componentsinthesystem before connectingthe speakers.The
amplifier has color-coded binding post connectors on the back panel. These
connectorsacceptbarewire,connectorlugs, ordual bananatype connectors.
(Exceptin EuropeanCommunity countrieswhere theiruse is not permitted.)
Route the wire from the amplifier to the speakers. Give yourself enough slack
so you can move the components to allow access to the speaker connectors.
If you are using dual banana plugs, connect them to the wires and then plug
into the backs of the binding posts. The thumbscrews of the binding posts
should be screwed in all the way (clockwise).
If you are using terminal lugs, connect them to the wires. If you are attaching
bare wires directly to the binding posts, separate the wire conductors and
strip the insulation from the end of each conductor. Be careful not to cut into
the wire strands. Unscrew (turn counterclockwise) the binding post. Place

15
the connector lug or wire around the binding post shaft or threaded through
the hole in the binding post. Turn the binding post clockwise to clamp the
connector lug or wire firmly in place.
NOTE: Be sure there are no loose wire strands that could touch adjacent
wires or connectors.
Cooling Fans 4
The Michi S5 / M8 is equipped with dual cooling fans to help ventilate the
internal components. It will adjust the fan speed automatically depending
on the temperature of the unit.
NOTE: The amplifier produces significant power and associated heat -
evenwith the cooling fansin use. Appropriateinstallationand ventilation
is required to ensure proper operation.

Troubleshooting
Most difficulties in audio systems are the result of incorrect connections, or
improper control settings. If you encounter problems, isolate the area of the
difficulty, check the control settings, determine the cause of the fault and
makethenecessary changes.If youareunable togetsound fromtheamplifier,
refer to the suggestions for the following conditions:
Power Indicator Is Not Illuminated
Thefrontpowerindication willbe illuminatedanytimethe unitis connectedto
AC power and the rear power switch is set to the ON position. The indication
willbe RED forstandbymodeandWHITE in normaloperation.If theindication
is not illuminated, test the power outlet with another electrical device, such
as a lamp. Be sure the power outlet being used is not controlled by a switch
that has been turned off. And check all AC power including the rear power
switch to ensure the unit is receiving power.
Fuse Replacement
Ifanother electrical deviceworkswhen pluggedinto thepoweroutlet, but the
Power Indicatorstillwill not illuminatedwhen theamplifier is pluggedintothe
walloutlet, itindicatesthat thepower fusemayhaveblown. Ifyou believethis
hashappened, contactyour authorizedMichi dealer toget thefuse replaced.
No Sound
If the amplifier is getting AC power, but is producing no sound, check the rear
panel BALANCED / UNBALANCED switch to ensure this is set to the proper
position matched with the analog source input. Also check if the speaker
cables are securely attached and the unit is not displaying a PROTECTION
message on the front panel TFT display.
Protection Indicator
Thefront panel POWER indicatoris redwhen theamplifierprotectioncircuits
have shut off the amplifier. Typically, this occurs only when the ventilation
openings are blocked, when there is faulty speaker wiring, or after a period
of extreme use. Turn off the system and wait for the amp to cool. Then push
the front panel power switch in and out to reset the protection devices. If the
problem is not corrected or reoccurs, there is a problem with the system or
the amplifier itself.
Function: The amplifier can be configured to display the input audio source
as either a dB Peak Power Meter or a Frequency Spectrum Analyzer. The
display can also be configured as OFF during normal operation. Select the
desired setting using the / Darrow buttons and press the Enter K
button to comfirm.
Options includes: VU Meter, Spectrum 8, Spectrum 12 (Default), Spectrum
