1. IMPORTANT REMARK
Congratulations! You are the owner of a carefully designed and manufactured equipment.
We thank you for having purchased our SMAC series mixer.
It is VERY IMPORTANT that you read this manual before connecting the mixer in order t o
obtain its maximum performance.
We recommend our authorised Technical Services whenever any maintenance task
should be needed so that optimum operation shall be achieved.
1.1. Precautions
This apparatus must be earthed through its mains cable.
Do not expose the unit to rain or water splashes, and do not place liquid containers or
incandescent objects like candles on top of the unit.
Any change in the configuration of the unit must be carried out by a qualified technician. Should any
connection / disconnection task be done, always disconnect the unit from the mains supply.
There are no user serviceable parts inside the unit.
2. INTRODUCTION
The SMAC series is a new and revolutionary mixer concept, designed by and for
PROFESSIONAL DJs, with ECLER’s state of the art performance and roughness.
The SMAC PRO40 introduces a new concept in the ECLER DJ mixers line, a compact size
mixer with 4 true channels and professional characteristics: balanced outputs, 2 channels with
assignable crossfader and three level inputs (PHONO, MIC, LINE).
Its new ergonomical design can be seen in the form and distribution of the controls and
connections. The SMACs are specially adapted to the latest trends in mixing, manipulation and audio
signal processing.
The sloped position of the main faders, the KILL system and the position of the PUNCH
buttons have been designed under ergonomic considerations.
The faders of the main channels, the PUNCH switches and the crossfader have been
grouped in an easy-dismounting module. The operating life of the crossfader has been extended up
to more than 300.000 operations (30 times more than a high quality mechanical crossfader) thanks
to the addition of an Voltage Controlled Amplifier (VCA). The VCA has also made possible the
implementation of a special transfer curve designed under DJ’s considerations. All these components
can be substituted by just using a screwdriver because they have multipin connectors.
The SMAC PRO40 has 4 mixable channels, with 7 stereo inputs: 3 PHONO, 2 CD
(compact disc) and 2 LINE, plus an extra microphone input.
All channels have an input lever switch selector and 3-band tone controls.
All inputs offer the PFL function in order to monitor any input signal, either visually (through
the VU Meter) or acoustically (with headphones).

3. INSTALLATION
3.1. Placement and mounting
The first thing to take into consideration when placing your SMAC is your comfort and an
easy access to all the connections.
The SMACs is basically conceived as a tabletop mixer and its usual placement will be
between two vinyl or CD players.
The optional metallic LSMAC side profiles kit allows you to firmly fix your SMAC to the
surface over which it is placed or over its own profiles (Fig.1).
These profiles also allow to tilt the mixer’s position for an easier operation.
Remember that the SMAC mixers have connectors in the front of the bo x and an external
connection must be provided when the unit is mounted on a rack.
Because of the high gain of the PHONO and MICROPHONE inputs, always try to place
the mixer as far away as possible from noise sources (dimmers, engines, etc...) and mains wires. For
the very same reason, and under any circumstance, should you ever remove the unit’s metallic
cover.
The power consumption of the SMACs is very low, so they don’t need an y cooling, but you
should avoid extreme temperatures and the atmosphere should be as dry and dust-free as possible.
The SMAC PRO40 operates under voltages between 90 and 264 V at 47 to 63 Hz. This
device features an over dimensioned power supply that adapts to the mains voltage in any country of
the world with no need to make any adjustments. Make sure that the mains wire (which plugs into
32) is far away from the signal cables in order to avoid any possible audio hum.
In order to protect the unit from an eventual electrical overload it carries a 500mA fuse
(32). Should it ever blow up, unplug the unit from mains and replace it with an identical one. If the
new fuse blows again contact immediately with our Authorized Technical Service. YOU MUST
NEVER USE A HIGHER VALUE FUSE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.
3.2. Input signal sources
-Turntables: They must be fitted with magnetic cartridges of 1.77 to 56mV nominal output
level. The PHONO inputs (25) of the SMACs have a very good headroom so they can accept high
output level cartridges. If you use moving coil cartridges they must be of high output level type and a
transformer or external preamplifier, placed as near as possible to the turntable, must be connected
between the cartridge and the mixer.
-Microphones: The Mic inputs (1-33), have a nominal input level of 0.562 to 17.7mV and
are equipped with XLR 3 and 1/4" jack connectors.
These inputs allow for the use of balanced wires. Connections are as follows:
XLR 3 1/4" jack
HOT or direct signal > Terminal 2 Tip
COLD or inverted signal > Terminal 3 Ring
GROUND > Terminal 1 Sleeve
6
Low impedance (200 to 600) monophonic microphones must be used. Shortcircuit pins 1
and 2 of the XLR connector or use a mono jack whenever an UNbalanced connection is desired. An
stereo jack can also be used for UNbalanced connections if the ring is shorted to ground.
CD, magnetophones, cassettes, tuners and video players: they can be connected to the
CD or LINE inputs. All these inputs can handle line level signals, but the SMAC’s has dedicated CD
(23) and LINE (24) inputs. The CD input sensitivity is +5dBV (1.778V) and the LINE input sensitivity
is –5dBV (562mV) so that nowadays sound sources requirements are completely fulfilled.
Direct access to the main mix: The SMAC PRO40 mixer have a direct access to the main mix
bus that enables the connection of the mixer to external effect units (see 4.6) or to other mixing units.
4. OPERATION AND USAGE
4.1. Start up
To switch the mixer on just push the switch labeled POWER (21) and the green pilot-light
inside the switch will light up. Although the switching noise produced by the SMAC PRO40 is very low
and almost inexistent when sta rting up the SMACs wit h the OUTPUT (19-20 ) control down, we high ly
recommend the "safe power-up seque nce": sound sources , mixer, equalizers, activ e filters and, finall y,
power amplifiers. Powering off should be done by following the exact reverse sequence in order to
avoid any possible damage to the loudspeakers.
4.2. Prelistening
The SMACs are equipped with a prelistening system that enables the monitoring of the
different inputs through the VU-meter and the headphones.
The Smac PRO40 has an advanced visual and auditive monitoring system. Two VUmeters unable simultaneous monitoring of the mix (left VU) and PFL or main OUT (right VU). Audio
monitoring is independent and the headphones can be fed with the PFL signal or both if the SPLIT
function is used. Placing the switch(36) on the SPLIT position will send the MIX signal to the left and
the PFL to the right.
4.3. Channel gain
All the SMAC input channels have accessible input sensitivity GAIN (4) controls. These
controls have the function of compensating for differences of level existing between the sound
sources connected to the table.
The gain controls have a variation margin of ±15dB. All GAIN adjustments must he done
very carefully using the VU-METER as a reference and avoiding that all the red LEDS of the VUMETER light up, input could be cliped.
4.4. Channel equalization
The 4 SMAC PRO40 channels are provided with a 3-way tone control (5-6-7) of wide
range of operation, ±15dB. This wide range enables a progressive KILL effect instead of the
sharpness of the ISOLATOR switch (15).
7
4.5.- Removeable / Exchangeable module (Faders, Crossfader with VCA, PUNCH, SHAPE)
The addition of the Voltage Controlled Amplification (VCA) control to the fineness,
precision and mechanical strength of the crossfader has resulted in an operating life greater than
300.000 operations. That means that the SMAC crossfader operating life is 30 times greater than a
high quality mechanical crossfader.
Once the operating life of the crossfader, SHAPE, PUNCH switches or faders has ended,
they can be easily changed proceeding as follows:
1.- Remove external screws of the module.
2.- Remove the module.
3.- Disconnect the multipin connectors.
4.- Remove the screws of the element to be replaced.
5.- Replace the desired element.
6.- Fix the new element to the module.
7.- Connect the multipin connectors.
8.- Place the module and fix the screws.
Always use original ECLER GENUINE SPARE PARTS for your SMAC
4.6. External effect output, EFF
Each mixing channel of the SMAC PRO40 are provided with a rot atory potentiome ter (8 ) to
send the signal to an external effect unit: sampler, rever,... The potentiometer controls the signal
level send to the external unit. The EFF output (27) must be connected to the input of the effect unit
and the output of the effect unit can be connected to the MIX input (26) or to a LINE input. The MIX
input is a direct access to the main mix bus and hence, no control is possible. But if a LINE input is
used, the signal can be processed as a normal sound source.
4.7. Crossfader assignement
The SMAC PRO40 has a crossfader with VCA and the adjacent channels (Channel 2 and
Channel 3) are permanently assigned to it. The remaining channels, can be assigned to any of the
crossfader extrems (A-B) by means of the 3-position lever switch (10). This switch can also bypass
the crossfader and send the signal directly to the mix bus.
4.8. Crossfader curve adjust:
Thanks to the VCA concept, it's now possible to modify the gain/attenuation behaviour of
the crossfader. The SMAC PRO40 provides this feature, enabling you to control the fade-in and
fade-out characteristics of the crossfader. The Crossfader knob XF SHAPE (12) at the housings
frontplate let you adjust the response curve from soft to hard independently so that you could
perform from sharp Scratch to smooth House techniques.
8
4.9. Effects: KILL, PUNCH.
The SMAC PR O40 have two groups of lever switches (15). Each group acts only on the
channel they are placed A or B. When the switches are used, the selected frequency range is
instantaneously eliminated. So, it is possible to mix the bass of a song (b y eliminating the m edium and
treble) with the medium and treble (by eliminating the bass) of another song.
The PUNCH switches (13) are also instantaneous . The music is instantaneously insert ed if
the crossfader is closed (opposite site of the switch pressed). The level of the punched channel
depends on the channel fader.
The combination of these elements offers an incredible fan of possibilities for your
creativity.
4.10. Outputs
Headphones: in order to obtain a high performance, these should be of the high
impedance type (200-600). Plug them to the HEADPHONES, PHONES (16) output, by means of a
standard 1/4" stereo jack. Sleeve is Ground, Ring is Right Channel and Tip is Left Channel.
The SMAC PRO40 have two main outputs, OUT1 (2 9-30) and OUT2 (28) with indep endent
rotative volume controls. A Balance control (36), co mmon t o both outputs , comple tes t he possibili ties of
the mixers.
You must be careful when setting up the general output level of the mixer. The “clip”
display of the connected power amplifiers must never remain permanently lighten up, but do it
occasionally by following the rhythm of the bass signals that are being played.
The SMACs are factory adjusted to 0dB/1V, though this can be internally adjusted to 10dBV/316mV, +4dBV/1,6V or +6dBV/2V (Fig.2). Just changing some soldering bridges.
ATTENTION: The modification of the output gain must be carried out by a qualified
technician.
The SMAC series mixers have a REC output (31) of -10dBV over 10k of load for a
nominal level input.
5. CONSIDERATIONS
5.1. Ground loops
Ensure at all times that no signal sources reaching the mixing desk and no devices
connected to its output have their earths interconnected; that is, earth should never reach them via
two or more different paths, as this coul lead to humming which could even interfere with sound
reproduction quality. In order to avoid earth loops, ensure that the shieldings of cables, if connected
to the chassis, are never connected with each other.
5.2. Audio connections
As a general rule of thumb, make the signal connections as short as possible and use the
best connectors and cable available. Cables and connectors are frequently undervaluated, forgetting
that a bad connection can result in a poor sound quality.
9
5.3. Background noise
The use of active circuitry can yield, depending on the configuration, to a significant noise
level. The SMAC series mixers have been designed for the minimum possible noise. Anyway, the
noise level will always depend on the correct use and installation of the mixer.
It is not the same setting up the “FADER” at “2” and the “MASTER” at “10” that the other
way round; “FADER” at “10” and “MASTER” at “2”. In th e first case you get a poor signal to noise
ratio that will be fully amplified by the master while on the second we have a good signal to noise
ratio only amplified by “2”. As a result, the background noise is greater in the first case than in the
second one.
5.4. Cleaning
The front panel should not be cleaned with dissolvent o r abrasive substances because silk-
printing could be damaged. To clean it, use a s oft cloth slightly wet with water and neut ral liquid soap;
dry it with a clean cloth. Be careful that water never gets into the unit through the holes of th e front
panel.

2. INTRODUCCIÓN
La serie SMAC representa un nuevo y revolucionario concepto de mezclador, diseñado
por y para los DJ PROFESIONALES con la fiabilidad de comportamiento y dureza ECLER.
La SMAC PRO40 introduce un nuevo concepto en la línea ECLER de mixers DJ, un
mezclador de cuatro vías reales de compacto tamaño y prestaciones totalmente profesionales:
salidas balanceadas, dos vías con crossfader asignable y la posibilidad de escoger entre tres
entradas de distinto nivel (PHONO; MIC; LINE), módulo central, son algunas de las características
diferenciales de esta mesa.
El innovador diseño ergonómico de esta serie se manifiesta en la forma y distribución de
controles y conexiones. Los SMACS están adaptados a las últimas tendencias en mezcla,
manipulación y procesado de la señal de audio.
La posición inclinada de los faders principales, su sistema Kill y la ubicación de los
PUNCH buttons facilitan unos movimientos corporales mucho más naturales y, por supuesto, una
mayor rapidez y seguridad en las manipulaciones.
Los componentes que sufren una ma yor manipulación se encuentran agrupados en un
módulo de fácil desmontaje: los faders de las dos vías principales, pulsadores de PUNCH y el
crossfader. El Crossfader incorpora un circuito electrónico VCA que extiende la vida útil a más de
300.000 operaciones (30 veces más que un crossfader mecánico de alta calidad). El VCA permite
además disponer de una curva de transición especialmente diseñada por Djs. Todos estos
componentes se sustituyen empleando únicamente un destornillador, ya que disponen de
conectores multipin.
12
El SMAC PRO40 dispone de 4 vías mezclables, con 7 entradas estereofónicas: 3 de
PHONO, 2 de CD (compact disc) y 2 de LINE, más 1 entrada preparada para micrófono.
Los canales disponen de un selector de entradas de palanca, y controles de tono de tres
bandas.
Todas las entradas disponen de la función PFL para monitorizar visualmente mediante el
Vu-Meter y acústicamente mediante auriculares cualquier señal conectada a las entradas de la
mesa.
3. INSTALACIÓN
3.1. Ubicación y montaje
La principal consideración a tener en cuenta en el momento de buscar la ubicación de su
nuevo SMAC debe ser la máxima comodidad de trabajo del operador, permitir una total facilidad en
la realización de las conexiones de las que el mezclador va a ser punto de partida y llegada.
Los SMAC están básicamente concebidos como mezcladores de sobremesa y su
ubicación habitual será entre dos reproductores de discos compactos o de vinilo.
Mediante el kit de laterales metálicos LSMAC (disponibles como opción) podrá sujetar
firmemente su SMAC, ya sea directamente sobre la superficie sobre la que se apoye o sobre los
laterales (Fig.1).
Estos perfiles permiten, además, inclinar la mesa para lograr así una mayor comodidad de
operación.
En cualquier caso, recuerde que los SMAC disponen de conexiones en el front al de la
caja, por lo que si el mezclador debe ser empotrado debe preveerse algún tipo de conexión exterior
de éstos elementos.
Dada la elevada ganancia de las entradas de PHONO y de MICRÓFONO debe
procurarse situar el mezclador lo más alejado posible de fuentes de ruido (variadores de tensión,
motores, etc,...) así como de cualquier cable de red. Por esta misma razón y bajo ninguna
circunstancia debe quitarse la tapa metálica del aparato.
Ya que el consumo del los SMACs es muy bajo, éstos no precisan ventilación, sin
embargo debe evitarse que estén expuestos a una temperatura extrema y que la atmósfera del local
en que esté emplazado sea lo más seca y limpia de polvo posible.
El SMAC PRO40 funciona con tensión alterna de 90 a 264V y 47 a 63 Hz. Este aparato
equipa una fuente de alimentación sobredimensionada capaz de adaptarse sin ningún tipo de ajuste
a la tensión de red de cualquier país del mundo. Debe evitarse que el cable de red (que se conecta
en 32) se entremezcle con los cables blindados que transportan la señal, ya que ello podría ser
causa de zumbidos a la salida.
Para proteger al mezclador de eventuales sobrecargas en la línea de red o bien excesos
ocasionales en el consumo de los circuitos internos, está provisto de un fusible (32) de red de
500mA. En caso de que éste se fundiera se desconectaría el aparato y se sustituiría por otro de
idénticas características. Si éste último se volviera a fundir, consulte con nuestro Servicio Técnico.
EN NINGÚN CASO DEBE PONERSE UN FUSIBLE DE VALOR MÁS ELEVADO.
PRECAUCIÓN: El cambio de fusibles debe ser realizado por personal técnico cualificado.
