Knoll SR62 Owner's Manual

SR62s Owners Manual
Congratulations and thank you for choosing Knöll inwall speakers!
To assure correct installation and to realize the full potential of these
new speakers, please read and follow these instructions carefully. If
you have questions or comments, please don't hesitate to call or write
your authorized Knöll dealer. Your dealer has the experience needed to pinpoint any problems that may exist
and has easy access to technical information from the Knöll factory.

Speaker Placement

Knöll SR62s speakers are designed to work within almost any interior-decorating scheme where inwall or
flush mounting is possible. Ideally SR62s speakers are ceiling mounted 2-3 meters (6'-10') apart, away from
corners directly over the listening area. This ideal placement gives the best stereo imaging. Position SR62s
speakers as symmetrically as possible. SR62s speakers can be ceiling or wall mounted.

Installation Tips

1. Follow all electrical and building code requirements in your area.
2. A minimum mounting depth of 3" (76mm) measured from the face of the wall or ceiling is needed in order
to fit properly. SR62s speakers can be placed right next to studs or other wall interior items but avoid near
proximity to pipes, machinery and high amperage wiring.
3. The mount wings provided with SR62s speakers can accommodate sheet rock or wallboard thickness of
1/2" to 1-3/8". Spacers or longer screws can be used on thinner and thicker surfaces.
4. Avoid mounting speakers closer than 0.5m (20") from a video monitor or TV screen. If any video or TV
screen distortion is detected, the video monitor or TV should be moved farther away from the speaker.
5. It is not necessary to install SR62s speakers in a special box unless required to do so by local electrical or
fire regulations.
6. Adding insulation such as 10cm (4") rock wool behind the SR62s generally improves sound quality.
7. Speaker wire should be minimum 16 gauge (ideally fire code rated), low oxygen wire. Runs longer than
10m (30') should be 14 or 12 gauge.
8. Parallel or series wiring is generally acceptable for SR62s speakers to obtain correct amplifier loading.
Avoid series wiring SR62s speakers with any other
speaker type.
9. Always take care to connect the speaker wire runs in
phase. An easy method verify polarity follows. Connect
a 1.5V battery across the speaker wire at the amplifier
location (see fig 1). Have someone observe if the SR62s
cone moves in or out. If the cone goes out (toward the
observer) the + wire is now connected to the + terminal
of the battery and that wire should be connected to the
+ terminal of the amplifier. Other speaker(s) should be
tested and connected in a similar manner.

Installation: Existing Construction
1. Use a stud locator device or other means to determine a suitable sized wall or ceiling cavity for the SR62s.
2. When ceiling mounting try to make the locations as symmetrical as possible. When wall mounting
carefully measure the distance from the floor to the speaker center so both speakers are exactly the same
distance from the floor. Draw a circular 7-1/4" hole at the correct location. Cut the hole out using a sheet rock
saw, keyhole saw or other suitable device. Place the SR62s in the hole to verify correct flush mount fit.
3. Run speaker wires from the amplifier to the room volume control location (optional) then to the left and
right speakers. Allow an extra 1m (3') of wire at the speaker cutout location to make installation easier. Strip
