5. In-wall Speaker Installation
To install a Studio Series in-wall speaker, proceed as described in
the following paragraphs and accompanying diagrams:
•
Having selected the installation position and checked for
the presence of studs (joists), pipe work, ducts or cables,
mark a portrait orientation cut-line on the wall using the
supplied template. Check that the dimensions of the cut-line
are correct: 175 mm x 275 mm (6.90 in x 10.83 in) for the
S4-W65 and 215 mm x 370 mm (8.25 in x 14.38 in) for the
S4-W80.
Note: Studio Series in-wall speakers are intended to be used in portrait
orientation.
Use an appropriate tool to cut along the cut-line to create a
1
cut-out in the wall. Trial fit the speaker Installation Frame in
the cut-out to check clearances.
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.
With the cut-out checked, the Installation Frame can be
2
installed. Insert the frame into place and while holding it
3
against the wall with one hand use the other hand to turn
and slide the four yellow securing clamps outwards and
slide them down 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 amplifier 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 Installation Frame and
wall cut-out. The length of free cable should be sufficient
to allow the Speaker Unit to be held in one hand while
connecting the cable to the Speaker Unit terminals with the
other hand.
The speaker cable can now be connected to the speaker.
4
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
5
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 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 the 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: Studio Series wall speakers are intended to be installed with the
tweeter above the bass/mid driver.
The high frequency tonal balance of the Studio Series
5
speakers can be adjusted to suit different installation
environments. A tweeter level switch located on the Speaker
Unit front panel offers +3 dB, 0 dB and -3 dB options.
The level adjustment operates from approximately 3 kHz
upwards.
Note: The +3 dB tweeter level option may be appropriate if, for
example, carpets, soft furnishings and curtains dominate in the listening
environment. Alternatively the -3 dB option may be more suited to an
environment where hard floors and glass predominate. In more balanced
acoustic environments, the 0 dB option is likely to be most appropriate.
•
With the speaker connected and secured into the Installation
Frame, in-wall speaker installation is completed by fitting
the grille. The grille is secured magnetically and requires 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 fitted during painting. They
should be painted separately.
