1.3 Technical notes
1.3.1 • Technical notes about inputs
The REVO IPA-80 amplier has 6 inputs, 2 of them are
congurable by the user.
The input IN 4, as well as being a normal input line, can
be congured as a Phono stage input for either MM / MC
The MC stage load can be adjusted internally using the
supplied phono stage manual.
The input IN 5, as well as being a normal input line, can
also be switched to a xed REC OUT by the remote control
pressing for 5 seconds the “SET” button. If you turn o the
amplier the REC OUT will switch back to IN 5.
The input “AV” (DIRECT) is useful, for example to connect
an external audio-video processor, only with integrated
volume control (home theatre, TV, DVD player). When
this input is selected the volume knob can’t control the
output level, it depends only on the input signal.
NORMA is not responsible of improper use of this input.
1.3.2 • Technical notes about connections
The device must be able to make the most of their features.
Nothing in the listening chain should be overlooked,
starting with the interconnect cables, which must be of
excellent quality, very transparent and neutral. NORMA
products are of extremely high quality and will benet
greatly with the use of appropriate cables.
Nothing in the listening chain should be underestimated,
from the quality of the cables to the position of the
speakers. For example, if cables used are of a low quality,
the resulting sound will be much less than the potential
of the device.
1.4 Warm up and run in
The warm up is a fundamental factor. For the best sound
performance we recommend an initial run of about 200
to 300 hours of operation with speakers connected and
music played at a normal listening level. After a long
period of inactivity, the unit will require at least 3 to 4
hours operation to reach the optimum performance
levels.
1.5 The problem of hum
Frequently the connection of multiple devices can cause a
certain amount of hum, even when the individual devices
are entirely silent. Connecting equipment together can
create ground loops which can introduce in the audio
signal path a certain amount of network harmonics. This
problem, which also aects professional installations,
is long-standing and not easy to solve. Its inuence is
particularly evident in the case of high gain ampliers
and in the presence of signals of very low amplitude. The
situation may sometimes be particularly noticeable with
phono stages, turntables and cartridges.
We point out some possible remedies:
• Reduce the connection cables length;
• Change signal cables and power cables position;
• Increase the distance between units, or arrange them
in a dierent way;
• Avoid using devices that can induce electromagnetic
elds or interference, such as electric motors, uorescent
lights or halogen lamp low voltage transformers;
• It may be useful to increase the signal connection
shielding from one side of the termination. If a device
proves to be involved in hum problems and / or ground
loops contact the manufacturer to try to solve the
problem;
• The electrical safety is due to its connection to safety
ground. Before connecting and using the device, make
sure that the grounding system is ecient.
NORMA is not responsible for any damage caused
resulting from wrong system grounding, or failure
to follow safety procedures and regulations or a
disconnection made in any way to the ground security
equipment;
• Check that the mains power cable has a ground
connection and do not remove it, for any reason;
• LED TV’s or PLASMA TV’s emit large amounts of infrared
rays that can interfere with the IR remote control signal;
• Most of the Revo IPA-80 produced since 2020 have an
internal DC lter in order to eliminate the DC oset on
the mains, normally this feature is disabled. For DC lter
activation contact NORMA or your supplier.

2.2 Turn ON / OFF
The REVO series ampliers are equipped with a
sophisticated power on system, integrated with the
system remote control and electronic protections. This
system consists of three phases: POWER OFF, STAND-BY,
POWER ON [OPERATE].
2.2.1 • Power OFF
In this phase, the rear control switch is in the OFF position
and the amplier is o.
2.2.2 • Power OFF to standby
Placing the rear control switch in the ON position, the
amplier is active in STAND-BY POWER indicator on the
front panel will be on with a low intensity. This condition
can be maintained indenitely, the amplication stages
are not powered, but the amplier is ready to receive the
command switch.
2.2.3 • Power ON [operate]
The power is on to all intents and purposes, this can
be determined by the prolonged action on the front
SEL button or IR remote POWER button. In both cases,
initially the indicator ashes for a period of time equal
to approximately 10 seconds. Subsequently, the light
indicator turns solid, indicating the complete operation
of the amplier and the connection to the speakers.
2.2.4 • Power ON to standby
To put the amp in STANDBY mode, press the SEL button
[or the POWER button on the remote control], the
indicator will switch to low-intensity lighting.
2.2.5 • Standby to power OFF
To POWER OFF the amplier, press the POWER button,
on either the remote control or the front panel of the
amp, and then put the rear control switch into the OFF
position. Never work directly on the rear control without
rst placing the amplier into STANDBY.
2.3 Protection circuit
Inside the amplier REVO IPA-80 there are some
sophisticated protection circuits that control the
temperature of the heatsinks, the presence of any oset
current exceeding the limit value and the abnormal
supply of output current (short circuit).
2.3.1 • Thermal protection
In case of activation of the thermal protection the
amplier will automatically shut down and the power
indicator lights will go completely o. The amplier
cannot be turned back on until the temperature has
returned to the correct value, and this will be indicated
by the POWER light in a low intensity. Only then can you
repeat the POWER ON procedure. The amplier will not
automatically restore the last used state.
2.3.2 • DC oset protection
In case of protection for the presence of a DC component
in the output signal, the amplier will turn o and the
power indicator switches to low intensity ashing. You
can turn it back on only after switching o the appliance
at the rear and leaving it o for at least 10 seconds. If the
fault persists, the amplier will run again in protection
mode. In this case disconnect all signal cables and repeat
the process of restarting the unit. Should the situation
persist, contact your service representative.The amplier
will not automatically restore its original state.
2.4 Inputs selection
Input selection takes place with a quick tap on the multi-
function control SEL switch. The inputs will be selected in
sequence IN 1, IN 2, IN 3, IN 4, IN 5, DIRECT. It is possible
to select the required input using the remote control
or via direct access with the numeric keys 1 - 5 or in
sequence with the SEL - / SEL +. For added convenience,
the REVO series ampliers have a resume function [the
state saved before shutting down], so that for each start
(from STAND-BY) the amplier is ready to use the input
selected before turning o. The stored conguration is
lost if you turn o the main power.
2.5 Selection of REC output
REVO series ampliers have the ability to connect a
recorder to the output REC OUT. It is possible to activate
and deactivate this connection only via remote control
with the prolonged action on SET (or short action on REC
button, if present) button on IR remote control. In order
to not introduce any noise, we recommend you keep the
REC OUT under OFF whenever it is not in use.
2.6 Selection of direct input (AV IN)
This input is congured as a direct input to the nal
section, for example to connect to an external Audio
Video processor. It is activated by remote control by
pressing the 6 key or by sequential selection. Selecting
this input, the listening volume is not adjustable by the
volume control, but depends only on the level of the
input signal. Pay attention to the input level, To avoid
sending too much power to the speaker.
REVO IPA-80 / User manual 3 • Maintenance 5
2.7 Listening volume control
The listening volume can be adjusted by the front
knob or the remote control, using the function keys
VOL - / VOL + (ne tuning) or VOL - - / VOL + + (quick
adjustment). To avoid damage to your speakers, before
turning on we recommend to always turning the control
fully counter clockwise to MIN. It is also advisable to set
the volume to a minimum during each input selection
and/or change of connection.
2.8 Connecting the speakers
The speakers are connected by cables to the SPEAKERS
OUTPUT sockets. Cables must be of adequate quality (at
least 4 mm ²).
In addition:
• The connection cables must have the same length for
both channels even if the distance between the speakers
and the amplier is dierent;
• The cables must not be piled up or rolled;
• Safety regulations require that the cables must not be
pushed into or wrapped around the 4mm banana plug
sockets of the amplier;
• In order to not overload the amplier, the speaker
impedance cannot be lower than 4 ohms;
• The speakers should not be connected in parallel with
each other.
Caution:
To prevent damage, each connection must be carried
out when the appliance is switched o and unplugged
from the mains.

Default conguration
Phono input conguration
The Jumpers J1A, J1B are located under the optional
phono board or under the USB board, if one of those
boards is tted and you have to operate under that you
have to remove it. Some spare jumpers are supplied in
the spare fuse bag, attached to the device instruction
manual.
1 • Default conguration
When J1A and J1B are tted the input IN4 is a normal LINE
input.
2 • Phono input conguration
If you want to t an optional phono board or an USB
board you have to remove both the jumpers.
Caution:
When you insert the PHONO board or the USB board,
be sure that jumpers J1A- J1B are removed, otherwise
may arise problems caused by the self-oscillation of
the board.
Note:
when the USB board is tted the Input IN4 cannot be used
as a LINE input.
Caution:
The conguration of the inputs involves the removal
of the top cover, therefore it is a potentially
dangerous operation. It must be carried out by
qualied personnel in compliance with all safety
standards. In particular, but not only, the device must
be disconnected from the mains and disconnected
from any other equipment, must be turned o for
at least 30 minutes and you must make sure that
all capacities are discharged. To be sure that the
capacitors are discharged there are 8 LEDs on the
main board, if the LEDs aren’t lit the capacitors are
completely discharged. If the conguration jumpers is
incorrect, the amplier can enter into self-oscillation,
this may cause damage to the speakers and the
amplier itself. Use extreme caution and possibly
connect the speakers after checking the correctness
of the conguration. We are not responsible for
wrong or partial congurations of these jumpers.
4.1.1 • Fuse replacing
Supplied with this device there is a small bag with some
spare screws, jumpers and fuses. If a fuse blows up there
is the possibility of replacing it but only with the same
type, voltage rating , current rating and most importantly
the action speed (slow “T” or fast “F”).
Caution:
Never bypass a fuse and never replace a blown fuse
with a dierent one. This may cause re and electric
shock. We are not responsible for any injury or
damage due to a wrong fuse replacing or any type of
tampering.
4.1.2 • DC lter
If you want to activate the DC lter you have to disconnect
the female Faston connector from the male plug DIR, then
connect it to the male plug FILT. This operation must be
carried out only with the power cable disconnected from
the mains.
Caution: shock hazard, this part of the
circuit is directly powered from the mains
and its capacitors could hold the charge for
long time after the shutdown. Disconnect this unit
from the mains and wait at least 30 minutes before
opening the top cover. The operation must be carried
out only by qualied personnel authorised service
centers. Wea re not responsible for any injury or
damage due to a wrong operation.
