Amplifier Precautions

Before using the power amplifier M-5000R, be sure to
read the page above entitled Important Safety Instructions
and this page of Amplifier Precautions.

Ventilation

While using the M-5000R, the internal temperature will
fairly rise. Excessive temperature rise may affect the
amplifier performance. To prevent damage from occurring
due to high internal temperatures, it is vital to have proper
ventilation and passage of air to carry out the heat and
keep the internal temperature within acceptable ranges.

Caution

• Do not place the M-5000R inside cabinets or closets
where there is poor passage of air and ventilation.

• Do not place the M-5000R near external heat sources
such as heaters or hot air ducts.

• Do not place other components or object on top of or
under the M-5000R.

• The cover of the M-5000R contains ventilation holes to
allow the passage of air. Do not cover or block these
holes in any way.

If you are planning to place it within a cabinet, either open
holes in the rear panel of the cabinet to improve
ventilation or use a fan to force air circulation.

As a general rule, if during idling the cover is too hot to
touch, then ventilation needs to be improved.

Installation location and space

Make sure that the floor or cabinet or rack where it will be
located is strong enough to support its weight.
You will also need to leave enough space behind the
M-5000R to allow room for the power cord and other
cables for connecting system components. A minimum of
10 cm (4") is required behind the M-5000R to allow room
for the cables and cords without excessively bending
them.
Do not place the M-5000R near TV or radio. This may
cause noise or instable video on radio or TV respectively.

Power cord

Do not use a power cord other than the one supplied with
the M-5000R. The power cord supplied is designed for use
with the M-5000R and should not be used with any other
device.
Be sure to only use wall sockets that properly fit the plug
of the power cord. If the socket does not match the plug of
the power cord, you will need to prepare an adapter.
Always use an adapter that is properly certified for this
application.

Speakers

Connected speakers should have an impedance of 4 ohms
or greater.
If speakers with an impedance of less than 4 ohms are
connected to RCA jacks, it may damage the M-5000R.
If a speaker with an impedance of less than 6 ohms are
connected to an XLR jack, it may damage the M-5000R.
Read the instructions supplied with your speakers.
Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive (+)
terminals, and negative (–) terminals only to negative (–)
terminals. If you get them the wrong way around, the
sound will be out of phase and will sound unnatural.
Unnecessarily long, or very thin speaker cables may affect
the sound quality and should be avoided.
Be careful not to short the positive and negative wires.
Doing so may damage the amplifier.
Make sure the metal core of the wire does not have contact
with the power amplifier’s rear panel. Doing so may
damage the power amplifier.
Don’t connect more than one cable to each speaker
terminal. Doing so may damage the power amplifier.
Don’t connect one speaker to several terminals.

(North American models)

If you are using banana plugs, tighten the speaker terminal
before inserting the banana plug.

Do not insert the speaker code directly into the center hole
of the speaker terminal.

Care

Power

From time to time you should wipe the front and rear
panels and the cabinet with a soft cloth. For heavier dirt,
dampen a soft cloth in a weak solution of mild detergent
and water, wring it out dry, and wipe off the dirt.
Following this, dry immediately with a clean cloth. Do not
use rough material, thinners, alcohol or other Chemical
solvents or cloths since these could damage the finish or
remove the panel lettering.
Whenever performing maintenance on the M-5000R, any
of its supplied accessories, or any device connected to it,
do not use solvents or cleaners of any kind that are
inflammable or combustible.
When you clean the input/output terminals on the rear
panel, do not use contact restorer. Doing so may cause
resin deterioration.
By factory default, the meters are treated with antistatic
coating. Do not strongly wipe the surface with a cloth to
avoid static electricity from building up, as this may cause
an oscillation of the needle.

Other

Below is a list of actions that you should never perform.

• Do not use the M-5000R as a broadcast system or
musical instrument amplifier.

• Never use a generator, DC/AC converter, AC/AC
converter, or transformer to supply power for the
M-5000R.

• Never perform a “thumb test” (checking whether current
is reaching the lead wire on the hot end of the input by
touching it with your fingers) on the ends of the input
jacks or input cables.
Doing so may damage the speakers.

• Do not short across the output terminals or across the
output terminals and rear panel.

• Never remove the cover of the M-5000R.

• Do not install the M-5000R in a location within the
reach of small children.

WARNING:

BEFORE PLUGGING IN THE UNIT FOR THE FIRST
TIME, READ THE FOLLOWING SECTION
CAREFULLY.
AC outlet voltages vary from country to country. Make
sure that the voltage in your area meets the voltage
requirements printed on the unit’s rear panel (e.g., AC
230 V, 50 Hz or AC 120 V, 60 Hz).

A WRAT (Advanced Wide Range Amplifier
Tec hno lo gy )

The M-5000R employs a host of proprietary
Onkyo technologies to ensure optimal audio
performance.

1. DIDRC (Dynamic Intermodulation
Distortion Reduction Circuitry)

Since the advent of digital audio, the values of
S/N (signal-to-noise) ratio have risen
significantly. However, it is also recognized that
in terms of perceived S/N, analog audio sources
are not inferior to digital sources.
Generally, S/N measures the ratio when sound
is and not produced, but takes no account of the
noise generated during sound reproduction.
For a long time, Onkyo has focused and made
extensive research on the S/N when sound is
produced (dynamic S/N). Using a mechanism
that captures the noise beyond audible range, it
has been possible to determine that both
dynamic S/N and perceived S/N aggravate
during music reproduction.
Although frequencies above 20 kHz are beyond
human hearing, it is well known that a beat can
be perceived if different signals are overlapped
at such frequencies.

During the analog audio era, no significant
signals were entering beyond the audible range.
However, the digital era has made recording
beyond the audible range possible and the
generated beat is now perceivable.

With Onkyo's DIDRC technology, a new
approach is introduced which prevents such
beat from penetrating the audible range.

2. Low Negative-Feedback Design

Conventional amplifiers make extensive use of
negative feedback (NFB), whereby part of the
output signal is re-input in order to improve the
S/N ratio across a wide frequency range.
However, too much NFB makes a system
susceptible to counter-electromotive force from
the speakers, resulting in a drop in perceived
sound quality. To avoid this, Onkyo focuses on
improving the frequency response and reducing
distortion, without relying so much on NFB.
We use a low negative-feedback design
incorporating audiophile-grade, close-tolerance
components, to achieve a frequency response,
out to 100 kHz.

3. Closed Ground-Loop Circuits

If an amplifier’s ground potential (voltage)
fluctuates during playback, noise is likely to
result. In an open-loop circuit design, where all
circuits (ire connected to the power supply via a
single loop (as on many amplifiers), the noise is
compounded. To avoid this, the M-5000R
employs a sophisticated closed-circuit design in
which each circuit has a separate link to the
power supply. This helps to cancel individual
circuit noise and keep the ground potential free
of distortion.

4. HICC (High Instantaneous-Current
Capability)

When an amplifier outputs an audio signal, the
connected speakers accumulate energy, reflex,
and send energy back to the amplifier. The
amplifier must then immediately cancel the
speakers’ reflex energy and instantaneously
send out the next signal. The same high current
required to achieve this is also necessary to

handle speaker impedance, fluctuations, which
can force an amplifier to provide four to six
times its usual current load. The M-5000R’s
instantaneous current capability ensures that
audio output is not affected by power
limitations.

Quad Push-Pull Amplification Design with
Three-Stage Inverted Darlington Circuitry

Three-Stage Inverted Darlington Circuitry
brings greater efficiency to the M-5000R power
amp by employing a low-NFB design to
maintain voltage stability and enhance transient
response. Extremely sensitive to oscillations,
this circuitry requires very advanced control
technology in order to be incorporated into the
amplifier. Breaking further new ground, the
M-5000R employs two extra transistors for
each channel in a “quad push-pull” design that
significantly enhances amplification power.

Symmetrical Twin-Monaural Construction

Power devices for the left and right channels of
the M-5000R are aligned symmetrically. Each
channel has the same electrical and structural
design, and signal pathways are uniform in
length. This helps to minimize errors in
stereophonic playback.

Side-mounted Circuit Board Construction

Rather than being directly connected to the
chassis base, the circuit boards inside the
M-5000R are cushioned by internal struts and
affixed to the front, side, and rear panels. This
method of construction prevents vibrations
from the chassis from adversely affecting the
circuit boards.

This is an example of the bi-amping connection using the preamplifier P-3000R.

Note

• Set the INPUT SELECT switch to RCA side.

Important:

• When making the bi-amping connections, be sure to remove the jumper bars that link the speakers’ tweeter (high) and woofer (low) jacks.

• Bi-amping can be used only with speakers that support bi-amping. Refer to your speaker manual.

This is an example of the bridge connection with the AV controller PR-SC5508.

Note

• When using the XLR inputs, do not connect anything to the RCA inputs. It may damage the power amplifier.

• Make sure that the XLR cable is not split. The split XLR cable may be the cause of noise.

• The power amplifier uses the European type XLR jack (pin 2 hot). If the AV controller/preamplifier with the USA type jack (pin 3 hot) is connected, the phase will be reversed. In this case, reverse the polarity of the speaker
connection.

•Set the INPUT SELECT switch to XLR side.

Tip

• After a certain period of warming up, the temperature of the
power amplifier’s components and internal temperature are
stabilized, and the sound will soften.

Note

• The power amplifier remembers the state when power was
previously turned off, and returns to the state.

Note

• See “Setting Auto Standby (ASb)” for the auto standby function
(➔ 21).

Switching the Power Meter Range

METER RANGE in the following order:
×1 (default), ×10, Off

The x1, x10 LEDs and the Off LED will light
according to the set status of METER RANGE.

The number of watts indicated on the meters corresponds
to the actual output level when driving speakers rated at 8
ohms. When driving speakers rated at 4 ohms, the output
is actually twice that shown on the power meters.

AUTO STANDBY

When AUTO STANDBY is turned ON side, the power
amplifier will automatically enter Standby mode if the
power amplifier receives no signal for 3 hours.

Set ON/OFF by switching the AUTO STANDBY

1

switch.

` ON:

ASb enabled.

` OFF:

ASb disabled.

Default setting: ON (European models), OFF (North
American models)
Once the ASb function has been activated, the power
amplifier will not automatically turn on even if it receives
the signal. To turn on the power amplifier, press
ON/STANDBY manually. You can also disable the
function by setting this switch to OFF side.

Note

• Before entering standby mode with the Asb function, the Off
LED flashes 30 seconds before the ASb function starts running.

Troubleshooting

Power

Can’t turn on the Power Amplifier.

• Make sure that the power cord is properly plugged into
the wall outlet (➔ 16).

• Unplug the power cord from the wall outlet, wait 5
seconds or more, then plug it in again.

The Power Amplifier turns off
unexpectedly.

• When the set ASb starts running, the power amplifier
will automatically go standby (➔ 21).

• If the power amplifier cannot start with the Standby LED
blinking, then it may be problem with the power
amplifier. If speaker cables touch the chassis, this may
cause the power amplifier to short out and make sure the
plus terminals of speaker cables do not touch the chassis
or the minus terminals.
Please try the method below:
–Set the POWER switch to OFF and disconnect all

speaker cables. Check that the top of the set (cooling
vent) is not blocked. When the power amplifier has
cooled down, reconnect all speaker cables and set the

POWER switch to ON. Then Press ON/STANDBY.

Audio

There’s no sound.

• Make sure the speakers are connected correctly (➔ 15).

• Check all connections and correct as necessary (➔ 15).

• When making XLR IN input, make sure that the INPUT
SELECT switch is switched to the XLR side.

• Make sure the correct input source is selected.

• Make sure the analog audio cable is connected correctly.

• Make sure that all audio connecting plugs are pushed in
all the way.

The sound quality is not good.

• Make sure the speaker cables are connected with the
correct polarity (➔ 15).

• Make sure all audio connecting plugs are pushed in all
the way (➔ 15).

• The sound quality can be affected by strong magnetic
fields, such as that from a TV. Try moving any such
devices away from the power amplifier.

• If you have any devices that emit high-intensity radio
waves near the power amplifier, such as a cellular phone
that’s being used to make a call, the power amplifier
may output noise.

• When making RCA IN input, make sure that the INPUT
SELECT switch is switched to the RCA side.

• Check the connection in case of bi-amping connection.

External Components

The 12V trigger does not work.

• Make sure the cables are connected to the jacks firmly.

The power amplifier contains a microcomputer for
signal processing and control functions. In very rare
situations, severe interference, noise from an external
source, or static electricity may cause it to lockup. In
the unlikely event that this should happen, unplug the
power cord, wait at least 5 seconds, and then plug it
again.

Before disconnecting the power cord from the wall
outlet, set the main power switch to OFF.

If during idling the cover is too hot to touch, then
ventilation needs to be improved.

Audio performance

• Audio performance will be at its best about 10 to 30
minutes after the power amplifier has been turned on and
had time to warm up.

• Using cable ties to bundle audio cables with speaker or
power cables may degrade the sound quality. So don’t
do it.
