2.2 Wiring

This device must be powered exclusively by earth con-

nected mains sockets in electrical networks compliant to
the IEC 364 or similar rules. It is absolutely necessary to verify this
fundamental requirement of safety and, in case of doubt, require
an accurate check by qualified personnel.

OUTLINE cannot be considered responsible for eventual
damages caused to persons, things or data due to an improper
or missing ground connection.

u Before powering this amplifier, verify that the correct voltage

rating is being used.

u Verify that your mains connection is capable of satisfying the

power ratings of the device.

u Do not use this amplilfier if the electrical power cord is frayed

or broken.

u Do not remove the cover. Failing to do so will expose you to

potentially dangerous voltage.

u Provide a sectioning breaker between the mains connections

and the amplifier. The suggested device is a 16A/250V AC, C
or D curve, 10 kA.

u Switching mode amplifier is capable of producing hazardous

output voltages. To avoid electrical shock, do not touch any
exposed speaker wiring while the amplifier is operating.

2.3 Speaker damage

Outline switching mode amplifiers are among the most

powerful professional amplifiers available and are capable
of producing much more power than many loudspeakers can han­dle. It is the user’s responsibility to use speakers suitable to the
amplifier and to use them in a sensible way that will not cause
damage.

Outline will not be held responsible for damaged speakers.
Consult the speaker manufacturer for power handling recom­mendations.

Even if you reduce the output volume using the amplifier’s
front panel attenuation controls, it is still possible to reach full
output power if the input signal level is high enough.

A single high-power tone can damage high frequency drivers
almost instantaneously, while low frequency drivers can usually
withstand very high, continuous power levels for a few seconds
before they fail. Reduce power immediately if you hear any
speaker “bottoming out”: harsh pops or cracking distor tion that
indicate that the speaker voice coil or diaphragm is striking the
magnet assembly.

Outline recommends that you use amplifiers in this power
range for more headroom (cleaner sound) rather than for in­creased volume.

This manual contains important information on operating your
Outline amplifier correctly and safely. Please read it carefully
before operating your amplifier. If you have any questions, con­tact your Outline dealer.

User Guide

5 Welcome

Congratulations on buying a Outline M5000-4 amplifier!
Outline is a leading company in the field of high efficiency
audio powe r management. The Outline Class D technolog y
has changed the way the world looks at professional audio
amplification: no other amplifier’s performance comes close for
applications demanding high power and long term reliability.
Thanks to amazing reductions in heat output and weight, without
sacrificing output powers, Outline amplifiers can be used in an
unlimited range of PA applications such as opera houses, theaters,
churches, cinema, and theme parks.

applications. This amplifier offer smaller dimensions, lighter weight
and the traditionally amazing sound quality and reliability of all
Outline products. M5000-4 amplifier have power ratings suitable for
a vast range of common applications including 70V/100V distributed
line systems

M5000-4 amplifier is specifically designed for touring and live

6.1 More sound and less weight

Switching mode technology based amplifiers are highly
efficient, delivering greater power to speakers with reduced heat
dissipation: typical running efficiency of output stages is 95%, with
only 5% of input energy dissipated as heat. This allows for smaller
dimensions, weight and power consumptions.

Contrary to conventional amplifiers which achieve highest
efficiency only at full rated power output, Class D efficiency is
almost independent of output level. Music has an average power
density of 40% of its peak value; this means that other (non­class D) amplifiers can easily generate 10 times more heat than
Outline products for the same sound pressure level.

The M5000-4 amplifier is designed to work with lo-Z (from
4 Ω) and with 70V/100V distributed lines. It can deliver up to

1250 W per channel (at 4 or 250 0 W in bridge mode on 8 Ω. Ω)

Outline amplifiers deliver crystal-clear highs, and a tight,
well-defined low end: the most accurate reproduction of an audio
signal. Solid time proven design features ensure extremely high
performance in terms of super low total harmonic distor tion,
optimal frequency response, high power bandwidth and damping
factor across a vast number of application scenarios.

Multi patented application of Pulse Width Modulation (PWM)
high frequency sampling techniques is just one of the many factors
contributing to the M5000-4 high performance ratings across the
audio bandwidth.

The M5000-4 offers complete protection against any possible
operation error. It is designed to work under a large range of
possible conditions, delivering maximum power with maximum
sa fet y and an outs tand ing lon g ter m rel iab ilit y. A nti cipa tin g
potential problems at the design stage means your show always
goes on!

7.1 Unpacking

Carefully open the shipping car ton and check for any noticeable
damage; the FIGU RE 4 shows the packing view. Every Outline
amplifier is completely tested and inspected before leaving the
factory and should arrive in pristine condition. In the unlikely event
that you should encounter any damage, please notify the shipping
company immediately. Be sure to save all packing materials for the
carrier’s inspection.

M5000-4

7.2 Mounting

All Outline amplifiers are designed for s tandard 19” r ack
mounting with four front panel holes and two rear-lateral holes. In
order to limit the risk of mechanical damages, amplifiers must be
fixed to the rack using both frontal as well as rear mounting holes
(see FIGURE 9).

7.3 Cooling

All Outline amplifier s implement a forced-air cooling system
to maintain low and constant operating temperatures. Drawn by
an internal fan, air enters through the slots in the front panel and
is forced over all components, exiting at the back of the amplifier.

The amplifier’s cooling system features an “intelligent” variable­speed DC fan which is controlled by heat sink temperature sensing
circuits: the fan speed will increase only when the temperature
recorded by the sensors rises over carefully predetermined values.
This ensures that fan noise and internal dust accumulation are kept
to a strict minimum. Should however the amplifier be subject to
an extreme thermal load, the fan will force a very large volume
of air through the heat sink. In the ex tremely rare event that the
amplifier should dangerously overheat, sensing circuits shut down
all channels until the amplifier cools down to a safe operating
temperature. Normal operation is resumed automatically without
the need for user inter vention.

Caution regarding heat escape should be exercised when
mounting M5000-4 amplifier. Exhaust cooling air is forced out
through the rear of the chassis (see FIGURE 5); make sure there
is enough space around the back of the amplifier for this air to
escape. M5000-4 amplifiers can be stacked one on top of the other
due to the ef ficient cooling system they are equipped with. There
is however a safety limit to be observed: in case a rack with closed
back panels is used, leave one rack unit empty every four installed
amplifiers to guarantee adequate air flow.

7.4 Operating precautions

Make sure the power switch is off before attempting to make
any input or output connections.

Make sure the AC mains voltage used is within the acceptable
operating voltage range specified in the M5000-4 documentation
(factory selected 115 V / 230 V ±15%), depending on your country

mains standard. Damage caused by connecting the amplifier to an
improper AC mains voltage is not covered by the warranty.

By using good quality input and speaker cables, the likelihood
of erratic signal behavior is reduced to a minimum. Whether you
make them or buy them, look for good quality wires, connectors
and soldering techniques.

7.5 Grounding

There is no ground switch or terminal on the M5000-4 amplifier.
All shield terminals of input connections are directly connected to
the chassis. This means that the unit’s signal grounding system is
automatic. In order to limit hum and/or interference entering the
signal path, use balanced input connections.

In the interests of safety, the unit MUST always operate with
electrical safety ear th connected to the chassis via the dedicated
wire in the 3-wire cable. Never disconnect the ground pin on the
AC mains power cord.

7.6 AC mains connection

The AC Mains connection is made via the IEC type connector
on the back of the amplifier. Please make sure your AC mains
power source operates within the voltage limits indicated on this
manual (factor y selected 115 V / 230 V ±15%).

Safety warning!

Ground wires must be connected!

Do not use adapters that disable grounding.

To take off the grey colored front panel, remove the two
screws highlighted in with a Philips screwdriver. The panel will
easily separate from the amplifier exposing the sponge-like air
filters.

Before replacing the front panel, remember to reposition the
air filter on the chassis by placing it on its designated area, then
reposition and tighten the two frontal screws.

8.2 Front panel adjustments

the user can modify the level of the input signal in steps corresponding
to a gain reduction ranging in:

-∞, 4, 14, 18, 20, 22, 24, 26, 28, 30, 32 dB.

8.3 Front panel monitoring

The M5000-4 front panel provides important information on
the state of the amplifier. It is impor tant to know and understand
the meaning of ever y front panel indicator LED in order to have
crucial information on the amplifier status.

There are two sets of LEDs on the M5000-4 front panel:
channel indicators and status indicators. Channel indicators: each
channel has its own column set of 4 LEDs. The top LED is red, and
the following three are green. Status indicators: each channel pair
has one set of two green status indicator LEDs.

The function of both families of LEDs is summarized in TABLE 1.

8.4 Connecting audio inputs

Audio input connections are made via four XLR connectors
found on the rear of the amplifier. Signal looping (i.e. link thru) is
possible using the two XLR male connectors which are also found
on the back panel. The Link on/off but tons allows to connect input
channels 1 and 2 (and/or channels 3 and 4) in parallel.

8.5 Connecting audio outputs

WARNING!

Lethal voltage levels may be present at the loudspeaker

connectors when the amp is turned on!

All output connections are made via speakON connectors.
Both bridge as well as single channel output connection modes
are available. In the single channel mode wiring, the 1+ pin of the
connector corresponds to the positive output of the channel, the
1– to ground (see FIGURE 9); for bridge mode refer to Section

8.5.2.

The M5000-4 amplifier manage bri dge and single chann el
mixed configuration; for example, channels 1 and 2 can be set
in bridge mode, and channels 3 and 4 single-ended.

M5000-4 amplifier is designed to be connected both to lo-Z
loudspeakers as well as hi-Z, 70V / 100V distributed lines directly.

8.5.1 Lo-Z and 70V/100V operations

High impedance loudspeakers can be par alleled in 70V/100V
distributed lines and directly managed.
High output voltage per channel g uarantees direct connection

to hi-Z loudspeakers in a line (see FIG URE 9).

8.5.2 Bridge Mode Connection

Bridge mode connection of outputs is possible only in lo-Z
operational mode. Bridging of adjacent channels is possible for the
following pairs: channels 1 with 2 and channels 3 with 4.
Bridging is NOT possible for other pairs, for example channels

9 Protection

In order to protect your device and your speakers from
ac cide ntal dam age, M500 0-4 ampl ifie r incl ude a n ext ensi ve
automatic protection system. In the following sections, potentially
dangerous scenarios and the amplifiers’ corresponding protective
response are explained in detail.

9.1 Turn on/Turn off muting

Class D amplifiers may cause severe speaker damage at power
up due to the high voltage levels at the output stage. In order to

avoid this, the outputs are muted for less than 2 seconds (less
than 5 seconds for DSP models) after turn on. Similarly, turning
off the amplifier can cause the same problem: outputs are muted
immediately at turn off.

9.2 Short circuit protection

Shor t circuits or very low impedance loads may destroy the
output stage of any amplifier. In order to protect the amplifier
from the dangerously high current surges arising from accidental
output shor t circuits or low impedance loads, all M series amps
block channel activity when the cur rent drawn from the load rises
above a set value. The channel is muted for 2 seconds after which
the amplifier will unmute the channel and check whether the
current draw is still over the safety threshold. Should this be the
case, the amplifier will mute the channels for another 2 seconds
and the procedure will reiterate. The red “CLIP” LED will be
turned off only when the output current draw will have returned
within safe limits.

9.3 Thermal protection

Outline M5000-4 amplifier have variable speed fans to assist
cooling. If for some reason the cooling system can’t dissipate
the produced heat correctly, a thermal protection system is
automatically activated to avoid permanent damages. Every
channel pair has a temperature sensor on the output stage
heat sink. Two different protection strategies are implemented
depending on the severity of the overheating. In order to protect
internal components, the amplifier may automatically reduce
output power until the internal temperature returns to safe levels.

9.4 Thermal warning

If the heat sink reaches a temperature of approximately 75°C,
the front panel red “TEMP” LED corresponding to the overheated
channel pair turns on to warn the user of a potentially dangerous
thermal event. Output power is reduced to prevent damages to
the output stage.

9.5 Thermal shutdown

If the heat sink temperature rises above 85°C, the thermal
sensing circuitry will mute each power section of each
compromised channel pair. Only after the heat sink has cooled
down to below 75°C the channel pair will automatically unmute
and the red “TEMP” LED will be turned off.

9.6 DC fault protection

In order to protect your speaker s from mechanical damage
caused by a DC signal coming from the amplifier’s output, a DC
detection circuit is placed between the amplifier’s output stage
and power supply. If a DC signal or excessive subsonic energy
appears at a channel output an instantaneous protection circuit
will mute the compromised channel pair. The red “CLIP” LED will
turn on to signal that protective measures have been engaged.

9.7 Input/output protection

Inter ference protection is implemented in the M Series to limit
out of band noise carried by the input lines. Disturbing frequencies
can interact with the output stage, causing unpredictable amplifier
behavior. A filtering system is used to s top infrasonic and VHF
signals from entering the signal path.

10 User Maintenance

10.1 Cleaning
