The loudspeaker is supplied with the following elements (apart from this manual):

• 1 power cord

• 4 rubber feet

• 2 adjustable spikes

• 1 rubber table stand

• 1 phase plug (tweeter)

• 1 protection grille for the tweeter with phase plug (we advise you to remove it before liste-

ning to the speakers.)

• 1 protection grille for the woofer (we advise you to remove it before listening to the spea-

kers.)

Please check that none of these items is missing, and remove all accessories from the box.

To remove the loudspeaker from its box without damage, open the end flaps fully and bend

them right back. Then remove the upper cushion and lift the loudspeaker out gently. Inspect

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

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).

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.

User Manual 6

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.
