Mounting Options
The vibration insulating Isolation Positioner/Decoupler™ (Iso-
Pod™) table stand allows tilting of the monitor for correct
alignment of the acoustic axis. The stand can be attached
to three points on the enclosure, allowing vertical and two
horizontal positions. Aim the monitor so that its acoustic axis
point towards the listening position (see Figure 3). Vertical
orientation is preferable, as this eliminates acoustical cancellation
problems around the crossover frequency. Place the monitors
symmetrically at equal distances from the listening position. If
possible, place the listening position on the left-right centerline
of the room (see Figure 4). When a monitor far away (1 to 2.2
m, 3-7 ft) from the acoustically hard wall behind the monitor, an
acoustic reflection from the wall may cause cancellation of low
frequencies and reduce bass output.
Acoustic reflections from objects like desks, cabinets, computer
monitors etc. can cause unwanted colouration and blurring of
the sound image. Minimise these by placing the monitors away
from acoustically reflective surfaces. Putting the monitors on
stands behind and above a mixing console usually improves the
response over placing monitors on a meter bridge. Symmetrical
positioning of the sound reflecting objects maintains a balanced
soundstage (see Figure 4).
A wide variety of ceiling and wall mounts are available through
your Genelec dealer. The 8340A can be fitted with König &
Meyer monitor mounts using two M6 x 10 mm threaded holes
on the enclosure back. There is an M10 x 10 mm threaded
hole in the base of the monitor. Do not use this thread for
mounting the monitor on a microphone stand. Monitor stands
typically have an incompatible 3/8” UNC thread. A wide
selection of accessories is available for Genelec monitors.

Front Panel Light
Normally, the light on the front panel is green, indicating normal
operational mode. Red and yellow colours are used to indicate
special situations. See Table 2 above.
Use with Subwoofers
Genelec recommends using the 7300 series subwoofers. For
more detailed system configuration and matching products,
please consult the on-line Genelec Product Selection Tool at
www.genelec.com.
Maintenance
There are no user serviceable parts inside the monitor.
Maintenance or repair must only be done by a Genelec certified
service.

Colour Indication
Solid greed Normal state, normal operation
Blinking green
GLM is adjusting the monitor
Green blink every 10 sec. Monitor is an ISS power saving sleep
state
Red blink Power amplifier overload protection is
active (audio is modified because of
protection)
Solid red Monitor is muted
Yellow Monitor is not in the active (playing)

overloading the monitor. If the AES/EBU cable is operated in
dual-wire mode, the monitor detects this automatically and the
channel selection switches have no effect.
Level
The Level switches scale down the monitor output level in 10 dB
steps. The effects of these switches add up and combine with
the effect of the rotary level adjustment control. The combined
total setting range is 42 dB.
Stored
Stored switch selects the use of the controls on the monitor’s
back panel or the settings stored inside the monitor memory
using the GLM system calibration software. Setting the Stored
switch to OFF position selects the settings defined by the
monitor’s own controls. Setting the Stored switch to ON position
selects the use of internally stored GLM settings. Using the
Stored option overrides all adjustments done with the monitor’s
own controls.
Operating Environment
These monitors are designed for indoor use only. The permissible
ambient temperature is 15-35 degrees Celsius (50-95°F) and
relative humidity 20% to 80% (non-condensing). When the
product has been stored or transported in cool environment and
is taken into a warm room, wait 0.5-1 hours before opening any
packing to prevent condensation of humidity before connecting
to mains power. Sufficient cooling must be ensured. The
minimum clearance is 50 mm (2 in) behind, above and on both
sides of the monitor. The space must be ventilated sufficiently
to dissipate the heat.
