the speaker for signs of any possible damage. In the unlikely event of this having occurred,
please inform the carrier and supplier. It is a good practice to keep the packaging in case of
future transportation.
Preliminary recommendations
We would like to give a word of warning about the high sound pressure levels that can be
generated by these loudspeakers, especially in a 5.1 configuration. Because of their low levels
of distortion, and the minimal fatigue incurred by the user, it is not always obvious to realize
the actual sound pressure level while working. Please bear in mind that exposure to excessive
levels over a sustained period of time may lead to permanent hearing loss.
Warranty
These products are guaranteed against defects in components and workmanship only, for a
period of 2 years. During the warranty period, Focal will, at their discretion, either repair or
replace products which prove to be defective, provided that the product is returned, shipping
prepaid, to an authorized Focal service facility.
Defects caused by unauthorized modifications, accident, negligence or any misuse are not
covered by this warranty. For further information, please contact your dealer or the distributor
in your country.

User Manual 4
A
CMS 50
The CMS 50 is an active 2-way near field
professional monitoring loudspeaker
(2 internal amplifiers), composed of a 5”
(13cm) Focal woofer/midrange speaker with
a Polyglass cone loaded in a large laminar
port and of a Focal inverted dome tweeter
in aluminum/magnesium (fig. A).
B
CMS 65
The CMS 65 is an active 2-way near field
professional monitoring loudspeaker
(2 internal amplifiers), composed of a 6.5”
(16.5cm) Focal woofer/midrange speaker
with a Polyglass cone loaded in a large
laminar port and of a Focal inverted dome
tweeter in aluminum/magnesium (fig. B).
Installation
Mains voltage
After having unpacked the unit, first check that the operating voltage is correctly
set (see location on rear panel). If it is not, adjust the selector to the appropriate
position. Also check and if necessary replace the fuse, which rating depends on
the operating voltage
(please refer to technical specifications).
Your products must be earthed using the power cord supplied.

User Manual 5
Audio input connections
The audio signal input is to connect, up to your own choice, whether to the XLR inlet or RCA
inlet.
The XLR inlet permits the connection of a source with symmetrical signal and uses standard
wiring instructions:
Pin 1 = Ground (shield)
Pin 2 = In phase voltage (“hot”)
Pin 3= Out-of-phase voltage (“cold”).
The RCA inlet permits the connection of a source with asymmetrical signal. It’s common to
link the out-of-phase voltage (Pin 3) to the ground (Pin 1). This connection is generally made
at wire level.
Tweeter phase plug
The CMS speakers are delivered with grilles for woofer and tweeter. In order to optimize the
sound stage precision, we advise you to remove the grilles thanks to the hook included in the
packaging. Then, install the phase plug on the tweeter in the vertical position by gently push
on the suburbs of the phase plug (see below).
Positioning
The CMS loudspeakers are near field monitoring loudspeakers and should be positioned at
a distance between 1 and 3 meters from the listener, pointing towards the listening position.
They can be sitting on the console top, hung or even placed on appropriate stands. In any
way, it is recommended that the tweeter is at a height from the floor approximately equivalent
to that of the listener’s ears. If required, it can make sense to place the speakers upside down
so that the previous rule is better fulfilled.
The CMS loudspeakers could be placed vertically or horizontally depending on the environ-
ment, preferably pointing towards the listener (fig. C, D, E).
Once the position is defined, you have 2 kinds of feet (4 rubber feet and 2 adjustable spikes)
to optimize the loudspeaker positioning (fig. F, G). The adjustment of the spike height permits
to control the height of the soundstage. The gap and the right/left positioning of each louds-
peaker permit to control the width, the centering and the global coherence of the soundstage
(left/center/right), at the source of your recording precision.
Running in
As in all brand new loudspeaker, the drivers need some run-in period: the CMS transducers are
mechanical elements demanding a little time to settle and adapt to the climatic environment.
This period will vary, depending on the working conditions and may take up to a few weeks.
Avoid pushing the speakers very hard during their first hours of use, but to accelerate the run-in
process, it is good practice to operate the speakers at moderate levels for 20 hours or so, with
programs having significant low frequency content. Only once the transducers have come to
stabilize will you get the optimum performance.

CMS 50 and CMS 65 controls
1 HI-PASS FILTER
The HI-PASS FILTER rotative switch permits to activate or not the 12dB/octave high-pass filter.
We advise you to set the rotative switch on FULL RANGE (deactivate the high-pass filter) in the
case of a use in stereo configuration (2.0). We advise you to use the positions 45, 60 or 90Hz
in the case of a use of the system with one or several subwoofers.
2 LF SHELVING
The LF SHELVING rotative switch permits to activate or not a correction of the sound level
under 450Hz. We advise you to set the LF SHELVING rotative switch on +2dB when the pre-
mises acoustics naturally softens that frequency range. We advise you to set the LF SHELVING
rotative switch on FLAT when the premises acoustics is neutral. We advise you to set the LF
SHELVING rotative switch on –2, -4, or –6dB when the loudspeakers are placed next to a wall
or an angle.
3 DESKTOP NOTCH
The DESKTOP NOTCH rotative
switch permits to activate or not
a correction of the sound level at
a central frequency of 160Hz for
a Q factor of 2. We advise you to
set the rotative switch on –2, -4 or
–6dB when the loudspeakers are
positioned on a table, a console
or any other support that creates
reflections.

User Manual 7
4 HF SHELVING
The HF SHELVING rotative switch permits to activate or not a correction of the sound level
from 4.5 kHz. We advise you to set it on:
• +2dB when the premises acoustics naturally softens this frequency range (mat environ-
ment).
• - FLAT when the premises acoustics is neutral.
• –2 or –4dB when the premises acoustics naturally increases this frequency range (brilliant
environment)
5 INPUT LEVEL
The INPUT LEVEL rotative switch function is to make the output sensitivity of the mixing conso-
le, or any other source, correspond to the input sensitivity of the loudspeakers. The available
sensitivities are +4dBu, 0, -10dBv. The +4dBu position corresponds to the professional stan-
dard. The -10dBv corresponds to the general public standard. The 0 position is an interme-
diate position.
6 FIXING POINTS
The fixing points are made to ensure the link between the loudspeaker and a fixing support
(stand, wall fixing, ceiling fixing, …). Please refer to page 11 to know the compatible fixations
(non-exhaustive list). The thread type is BSW 3/8”.
7 BALANCED INPUT
The XLR inlet permits the connection of a source of symmetrical signal and follows standard
wiring instructions.
Pin 1 = ground (shielding)
Pin 2 = In phase voltage (hot)
Pin 3 = Out-of-phase voltage (cold)
8 UNBALANCED INPUT
The RCA inlet permits the connection of a source of asymmetrical signal. It is common to link
the out-of-phase voltage (Pin 3) to the ground (Pin 1). This connection is generally made on
the wires.
9 ON/OFF Switch
The ON/OFF switch permits to put the internal amplifiers ON or OFF.
10 ON/STANDBY Switch
The ON/Standby switch permits to activate or to put the CMS loudspeaker in Mute. The LED is
green when the loudspeaker is activated. The LED is red when the loudspeaker is in Standby.
11 VOLUME
The level rotative switch permits to adjust the level of the CMS loudspeaker. In position 0
(complete counterclockwise rotation), the loudspeaker is in Standby. In position 1(complete
counterclockwise rotation + 1 notch), the softening is of –66dB. The last notch (complete
clockwise rotation), corresponds to 0dB.
12 LED
The LED is red when the loudspeaker is in standby. The LED is green when the loudspeaker
is activated.
13 CLIP INDICATOR
The clip indicator permits to control the audio signal quality. When the LED is lit up, the clip is
activated. It means that the signal is saturated and does not permit to work in good conditions.
You must avoid activating the clip. To do so, you must reduce the input signal level in the CMS
loudspeaker and/or reduce the loudspeaker sound level 11.
