1. Introduction
This manual describes the installation of S4-LCR Series modules within drywall/plasterboard walls. It begins by listing the carton contents and continues information specic to installing in-wall speakers.
If this is your rst time working with Dynaudio Studio Series custom install speakers, or if you have not done so for a while, we recommend that you read the appropriate sections of this manual before you begin.
Note: Visit dynaudio.com for the latest Studio Series news and information.
The S4-LCR Series is designed to provide very high quality left, centre, and right channel audio in custom installations where speakers are required to be tted ush in walls. The S4-LCR Series not only benets from four decades of Dynaudio speaker expertise but has been designed through its modular format to offer enhanced versatility in terms of both practical installation and acoustic performance.
S4-LCR Series modules comprise a Speaker Unit and Installation Frame. The Installation Frame is inserted into the wall cut-out and securely xed in place using auto-locking clamps. The Speaker Unit is then connected to the speaker cables before being inserted into the Installation Frame to be held in place by a latch system. The grille is then tted, secured by magnets integrated within the Installation Frame.
• S4-LCR Series modules are uniquely simple to install. Once a wall cut-out is created, no tools are required and installation can be completed by one person without assistance. Every element of the S4-LCR Series installation procedure, from unpacking the speakers to painting and tting the magnetic grilles is simplied and streamlined by design.
• S4-LCR Series speakers employ numerous Dynaudio technologies, borrowed from the company’s studio monitors and high-end hi- speakers, to bring genuinely high performance audio to custom installations: unique bass/mid drivers with large diameter aluminium voice coils and nite element optimised, low­distortion magnet systems, proprietary MSP (Magnesium Silicate Polymer) diaphragms, and precision coated soft dome tweeters with powerful neodymium magnets are just a few examples among many.
• The S4-LCR Series comprises two modules: the S4-LCRMT mid/tweeter module and the S4-LCR65W twin driver bass module. A single S4-LCRMT module can be used with one or, for higher volume level applications, two S4-LCR65W modules.
• S4-LCRMT sensitivity can be adjusted via a rear mounted switch to match either one or two S4-LCR65W modules. The electrical crossover between S4-LCRMT and S4-LCR65W modules can be accomplished passively, using either the standard internal passive lters, or actively using external active lter components. Switches and bypass jumpers located on the rear of the speaker units engage or bypass the internal passive bass module low pass and mid/tweeter high pass lters.
1.1 Carton Contents
The carton contents for all S4-LCR Series modules are essentially the same. Items only differ in terms of format and dimension. Within each carton can be found:
1 x Speaker Module 1 x Installation Frame 2 x Frame Flange 1 x Cut-out Template 1 x Paint Mask 1 x Document pack
A typical carton contents is illustrated in Diagram 1.

S4-LCRMT
• Each S4-LCR Series module is supplied with a pair of Installation Frame Flanges. With frame anges tted, modules can be installed individually and spaced apart. With one or both frame anges removed, multiple modules can be consolidated and installed in a common wall cut-out.
• S4-LCRMT modules are intended to be installed only in portrait orientation, however S4-LCRMT speaker units can be rotated within their installation frames in order that the frames match the orientation of adjacent S4-LCR65W modules.
• S4-LCR65W modules can be installed in either landscape or portrait format. In either case, multiple modules can be either consolidated for installation in a common wall cut-out, or installed in individual wall cut-outs.
Grilles are not supplied with S4-LCR Series modules but can be supplied as accessories in a range of lengths to suit installation congurations. S4-LCR grilles attach magnetically and fully paintable.
Installation Example A:
• Left, centre and right speakers installed with 42” TV in a dry wall with simple 400mm (16”) stud spacing.
• Each Left and Right speakers comprises one S4-LCRMT and one S4-LCR65W consolidated in a common wall cut-out. S4­LCRMT upper frame ange and S4-LCR65W lower frame ange tted.
• Centre speaker comprises one S4-LCRMT and two S4-LCR65W mounted in separate wall cut-outs. All frame anges tted.
Installation Example B:
• Left, centre and right speakers installed with 42” TV in a dry wall with modied 400mm (16”) stud spacing. Stud arrangement congured to create centre speaker aperture.
• Each Left and Right speakers comprises one S4-LCRMT and one S4-LCR65W consolidated in a common wall cut-out. S4­LCRMT upper frame ange and S4-LCR65W lower frame ange tted.
• Centre speaker comprises one S4-LCRMT and two S4-LCR65W consolidated in a common wall cut-out. S4-LCR65W left and right frame anges tted.
2. Preparation
Before commencing any S4-LCR Series installation you must be sure that the wall positions chosen are free of obstructions such as pipe work, ducting or wiring that might interfere with the installation. Stud-nding, pipe detecting and wire detecting tools can help map the wall construction and identify any potential obstructions.
2.1 S4-LCR Series Module Selection
The modular format of the S4-LCR Series enables a variety of arrangements of mid/tweeter (S4-LCRMT) and bass modules (S4­LCR65W) to be installed to suit different front channel requirements. The S4-LCR Series modular format also enables in-wall front channel speakers to be installed around the constraints that may result from dry-wall stud spacing. Three typical installation examples are illustrated below.
Left and right speakers can be created from an S4-LCRMT module combines with either one, or in larger listening spaces, twin S4­LCR65W modules. Centre channel speakers always require a single S4-LCRMT and twin S4-LCR65W modules.
2.2 S4-LCR Series Installation Examples
Installation Example C:
Left, centre and right speakers installed with 65” TV in a dry wall with simple 400mm (16”) stud spacing.
• Each left and Right speaker comprises one S4-LCRMT and two S4-LCR65W consolidated in a common wall cut-out. S4­LCR65W lower and upper frame anges tted.
• Centre speaker comprises one S4-LCRMT and two S4-LCR65W mounted in separate wall cut-outs. All frame anges tted.
2.3 S4-LCR Series Cut-out and Clearance Dimensions
The S4-LCRMT and S4-LCR65W modules require specic wall cut-out dimensions but have common mounting depth space and drywall (plasterboard) thickness constraints. These dimensions are illustrated in Diagrams 2 and 3 and listed in the table. Diagrams 3A to 3C also illustrate an S4-LCR module with Frame Flanges tted and removed, and an S4-LCRMT and S4-LCR65W module consolidated.

2.4 Back Boxes
In-wall speakers are often installed with back boxes in order to reduce sound transmission into adjacent rooms or to satisfy any local statutory building regulations. S4-LCRMT modules however incorporate an integrated back box so none is needed on installation.
S4-LCR65W modules do not incorporate a back box and if back boxes are to be used they must be installed within the walls before the drywall (plasterboard) is afxed to the studs. Alternatively, the existing drywall (plasterboard) around each speaker installation position may be removed to enable a back box to be installed. The drywall (plasterboard) should be reinstated following back box installation.
Dynaudio does not supply back boxes suitable for S4-LCR65W modules however, back boxes from alternative manufacturers may be used, or back boxes may be constructed on site. In either case, each S4-LCR65W module requires a 30Litre (1.1ft3) minimum back box volume in order to reach its full audio performance potential.
Check with local building regulations for re safety. In some areas it is required to have a re­rated back box as a re safety barrier. Ensure that the surrounding materials meet the ammability Class 5VA. A re rated metal back box must have a minimum uncoated thickness of 1.35mm.

3. Speaker Positions
S4-LCR Series modules are designed specically for front and centre channel applications in multi-channel audio visual installations. Position guidelines and diagrams are covered in the following paragraphs and illustrated in Diagram 4.
The left and right speakers should be located either side of the screen. The centre channel speaker should be located centrally above or below the screen, ideally less than 0.25m (10in) away.
In the case of acoustically transparent screens the centre channel speaker should be located centrally behind the screen.
Note: The nature of the installation of custom install speakers means that it is sometimes impractical to locate them in acoustically optimal positions. Compromise is often more likely to be necessary in multi-channel installations where positions have to be found for multiple speakers. In these circumstances it is preferable to favour the position of the front and centre channel speakers over that of the surround channel speakers.

4. Connections and Mode Settings
S4-LCR Series systems can be connected in either passive or active mode. Diagrams 5 to 8 illustrate passive and active connection of systems comprising both one and two S4-LCR65W modules.
4.1 Passive Mode
• In passive mode, the S4-LCRMT and S4-LCR65W modules employed for each channel are connected in parallel to a single power amplier channel.
• The mode selection switch on the rear of the S4-LCRMT module should be switched to “1W” if one S4-LCR65W is used (per S4­LCRMT) and switched to “2W” if two are used. Ensure that the
mode selection switch position is correct before use.

IMPORTANT Ensure that the mode selection switch position is correct. Damage may result if the switch position is incorrect.
• The two mode selection jumpers on the crossover PCB of each S4-LCR65W module should be located in the J1 position. The mode selection jumpers can be accessed by lifting the crossover assembly from the back of the S4-LCR65W module. This is achieved by removing the four screws identied in Diagram 5.
Note: S4-LCR65W modules are initially supplied with their jumpers in the J1 position. Jumper position should however always be conrmed visually before S4-LCR65W modules are installed.

4.2 Active Mode
• In active mode, each S4-LCRMT and single or multiple S4­LCR65W module employed for each channel is connected separately to a power amplier channel.
• The mode selection switches on the rear of each S4-LCR65W module or modules should be switched to “BYP” (bypass).
Ensure that the mode selection switch position is correct before use.
• The two mode selection jumpers on the crossover PCB of each S4-LCR65W module should be located in the J2 position. The mode selection jumpers can be accessed by lifting the crossover PCB module from the back of the S4-LCR65W module. This is achieved by removing the four screws identied in Diagram 7.
• The power amplier channel driving each S4-LCRMT and S4-LCR65W modules must be driven via active lters. The recommended lter characteristics are tabulated below.

Note: Where a S4-LCRMT module is used with a single S4­LCR65W module ,the S4-LCR65W gain should be reduced by
-6dB.
5. Speaker Installation
To install S4-LCR Series modules, proceed as described in the following paragraphs and Diagram 9:
Note: Diagram 9 illustrates the installation of a S4-LCRMT module. S4-LCR65W and multiple module installation is carried out in the same manner.
• Having selected the installation positions and checked for the presence of studs (joists), pipe work, ducts or cables, mark cut-lines on the wall using the supplied template or templates. Check that the dimensions of the cut-line are correct.
Note: In order to reduce the possibility of audible wall vibration it may be prudent to apply a bead of adhesive mastic between the wall studs and the drywall (plasterboard) in the vicinity of wall speakers.
Use an appropriate tool to cut along the cut-line to create a cut-out in the wall. Trial t the Installation Frame or frames in the cut-out to check clearances.
With the cut-out checked, the Installation Frame or frames can be installed. If frame anges are required these should be tted at this stage. If the installation comprises multiple S4-LCR modules, all installation frames should be tted at the same time.
To install an Installation Frame, insert the frame into the wall cut-out and while holding it against the wall with one hand. Use your other hand to turn four yellow securing clamps outwards and slide them down securely against the inner surface of the drywall (plasterboard).
Note: If speaker cables are not already installed it should be done at this stage. It is possible that access will be required through the opposite side of the wall to route the cables. Use low resistance speaker cable with clear polarity marking on its insulation. Low resistance is especially important if the length of cable from amplier to speaker exceeds 5m. Your local Dynaudio retailer or distributor will be able to offer advice on speaker cable selection if required.
• Pull the speaker cable through the appropriate Installation Frame and wall cut-out. The length of free cable should be sufcient to allow the Speaker Unit to be held in one hand while connecting the cable to the speaker terminals with the other hand.

The speaker cable can now be connected to the Speaker Unit. Strip 15mm insulation from the cable (if necessary), twist the wire strands and insert the stripped ends into the speaker spring terminals. Ensure that the positive conductor is connected to the red speaker terminal and the negative conductor is connected to the black speaker terminal.
With the Speaker Unit connected to the speaker cable it can be inserted into the Installation Frame. Turn the locking tabs on the front surface of the Speaker Unit fully clockwise (aligned with the lock icons) and insert it in the Installation Frame. Push gently around each locking tab until a click is heard. The Speaker Unit will then be secured in the Installation Frame.
Note: Take care that the cable is positioned in such a way that it will not get trapped as the Speaker Unit is secured into the Installation Frame and is not touching the Speaker Unit in such a manner that it is likely to result in audible vibrations.
Note: To remove a Speaker Unit from the Installation Frame turn the locking tabs 90° counter-clockwise. Take care to support the speaker as the locking tabs are turned.
Note: The high frequency tonal balance of S4-LCRMT modules can be adjusted to suit different installation environments. A tweeter level switch located on the Speaker Unit front panel offers +2dB and -1dB options. The level adjustment operates from approximately 3kHz upwards. The +2dB option may be appropriate if, for example, carpets, soft furnishings and curtains dominate in the listening environment. The -1dB option may be more suited to an environment where hard oors and glass predominate.
• With speaker units connected and secured into in installation frames, installation is completed by tting grilles. Grilles are secured magnetically and require no more than placing into position.
Note: If the wall is to be painted following speaker installation, the supplied paint mask must be used to protect the speaker hardware from paint ingress. Speaker grilles should not be tted during wall painting. They should be painted separately.
