Brunetti pleximan User manual

USER MANUAL
This manual contains a lot of information required to have in-depth knowledge of
the equipment. Therefore we recommend that you read this manual carefully in
order to use its potentials to the very best. All of our products are made on an
artisan basis and therefore you may find some small acoustic and/or structural
differences. This is the very best guarantee of a truly hand-made product.

THANK YOU FOR CHOOSING THE BRUNETTI PLEXIMAN AMP.
THE PURCHASE OF A BRUNETTI PRODUCT IS NOT JUST A
FINANCIAL TRANSACTION, IT’S THE BEGINNING OF A “RELATIONSHIP”
BETWEEN US AND OUR CUSTOMER.
IT’S OUR MISSION IN LIFE TO SATISFY YOUR EXEPCTATIONS FROM
YOUR INVESTMENT IN THE BRUNETTI BRAND.
Marco Brunetti
PLEXI
To celibrate 25 years of Brunetti, we wanted to design a new model that would make history
in the world of guitar amplication. e Pleximan is the result of our eorts. is very
special head is small in size, but is incredibly powerful. It has many similarities with its older
‘sister’, the Customwork Mercury. ere are two tube powered channels plus other new
features that add two extra channels, giving you four individual sounds with simple and
eective operation. e philosophy of "less is more" is truly demonstrated by the Pleximan.
Powerful but tame, the 50W/5W power amp is powered by EL34 tubes. Gorgeous, british
rock sounds to suit a variety of musical genres are delivered eortlessly.
e Pleximan works perfectly with the Singleman 1x12 Vintage 30 Cab or the more powerful
Customwork CW212 2x12 Vintage 30 Cab. Connect your choosen cabinet to the Pleximan,
switch the power on and read this manual. You will then be ready to play and experience the
emotion of Brunetti!

Channel 1 is able to give many tonal nuances. Its characteristic is to add
harmonics to the dynamic without distorting the basic sound.
It can generate very clean tones, but also compressed and emphasised
harmonics (Dense mode). Warm and full-bodied, it is a classic British Plexi
style channel, but with a new Brunetti shape. Simple, yet
eective with very intuitive controls, this channel works perfectly with the
range of stomp pedals. A real ‘all-rounder’ channel.

Channel 2 is designed with smooth or heavy distortion in mind. We have created it to be dynamic, but also
with the right amount of compression. is is not a hi-gain ‘metal’ channel, but it can be ‘cranked up’ high
without generating any annoying sharp or dissonant harmonics. Incomparable timbre,
from smooth blues rock to crunchy and dened full-bodied tones.
e ‘Hotrod’ mode delivers a true 80’s/90’s sound. e hot and uid distortion previously delivered by the
Mercury Customwork range is evident in this mode. e classic stack EQ with the ‘MELLOW’ switch soens
the tone. e ‘EXTRA’ function boosts a broad spectrum of midrange frequencies giving an incredible ‘punch’
to the overall sound. Simple and full of energy as per the Brunetti philosophy.
e Pleximan also has a ‘SOLO’ function as seen on the Customwork series.
is convenient function more than doubles the output volume of the amp
and is controlled via a simple footswtich.
e Pleximan is equipped with a power limit switch that steps down the
power from 50W to 5W. When this mode is selected, a frequency compen-
sation system is automatically engaged to give the same ‘punch’ at lower
volumes.

ere are two, connected speaker jack outputs.
When using only one speaker cabinet, set the total impedance
equal to the impedance of the cabinet itself.
When using only two speaker cabinets of the same impedance, set the
total impedance to half that of the nomainal cabinet impedance.
For example, to connect two 16Ω cabinets to the Pleximan, the
impedance selector should be set to 8Ω.

- Each tube is selected and matched to the amp during the electrical and sound testing
procedure.
- Only replace defective tubes with the exact same model (better if supplied by Brunet-
ti).
- e EL34 power tubes require bias adjustment aer replacement.
Failure to use the correct type of valve may result malfunction of the amp.
CAUTION!
Inside the amplier there are potentially lethal voltages. If your unit requires repair or
service please contact Brunetti or a Brunetti approved service centre.
Qualied technicians guarantee that the work is carried out correctly.

ch hotrod solo
Ensure that connection of the two footswitch jacks corresponds to RED
and BLACK as shown on the diagram to the rear of the unit. Inverted
connection will not cause any damage, but the switching will not function
correctly. Each function can be remotely switched by a latching command

e main functions ‘CH’, ‘HOTROD’ and ‘SOLO’ are footswitch
controlled and must be connected to the jacks ‘FOOTSW’. e
footswitch pedal has two jacks. e black cable jack is for ‘CH’ and
‘SOLO’. e red cable jack is for ‘HOTROD’. In order to have the
footswitch correctly working the two jacks must be connected both.
“DENSE” function can be switched remotely by an on/o switch.
e manual switches on the front panel must be selected as follow:
CH switch in CH2
ch
Hotrod
HOTROD switch in OFF position

REMOTE SWITCHING
e functions ‘CH’, ‘HOTROD’, ‘SOLO’ and ‘DENSE’ can also be
switched by remote jack by connecting latching command ON/OFF
Take care to use a stereo jack with two mono jacks for CH and
SOLO as shown on the diagram.

PARALLEL LOOP
This connection is good only for

In order to achieve a great sound you
MUST exclude the DRY SIGNAL from
the fx-processor (by using its internal
mixer).
GENERAL INFO ON EFFECTS & LOOP
FILTER EFFECTS
The filter effects main feature (see example) is the physical alteration of the signal wave, as a distortion pedal does.
This family of effects finds its best place between guitar and preamp input.
MODULATION EFFECTS
The modulation effects main feature (see example) is the addition or the overlapping of other curves or waves to the
input signal. This family of effects finds its best place in connection to the effects loop, i.e. between preamp and power
amp.
SERIAL LOOP
In the serial loop all the signal getting out of the preamp passes through the effects chain of the loop. During the
setting of the effect you have to consider that the sound is composed by a share of the original sound (DRY) and a
share of the processed sound (WET). They both come from the original sound and are mixed (MIX) INSIDE the effect
processor before being sent to the outputs.
PARALLEL LOOP
In a parallel loop a share of the signal getting out of the preamp passes unaltered through the loop circuit (DRY) and
a share reaches directly the SEND. The latter is processed by the effects, sent to the RETURN and then mixed with
the DRY. The effect quality is less important here than in the serial loop because the original DRY signal will be not
“colored” when it passes through the loop or the effect and the WET signal will be pleasantly added to the DRY signal.
