ISS
This switch activates or deactivates the ISS automatic power
saving function. The default time for ISS activation is 60 minutes,
but the time can be adjusted in the GLM software.
Digital
The Digital switch selects the digital audio channels on the
AES/EBU. Turning both switches on reproduces the sum of the
A and B channels. When both channels are selected 6 dB of
attenuation is applied to avoid overloading the monitor.
Level
The Level switches reduce the monitor output in 10 dB steps
(-10 dB, -20 dB and with both switches set to ON, -30 dB). The
effects of these switches combine with the effect of the rotary
level adjustment control. The total setting range is 42 dB.
Stored
The Stored switch selects between the application of the
above listed controls on the monitor's back panel and applying
the settings stored inside the monitor memory using the GLM
calibration software. Setting the Stored switch to the OFF position
selects the settings defined by the monitor's controls. Setting the
Stored switch to ON position selects the use of internally stored
GLM settings and the adjustments on the monitor have no effect.

Operating Environment

This product is 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). To prevent
condensation of humidity, after the product has been stored
or transported in a cool environment and is then taken into a
warm room, wait 0.5-1 hours before opening the packaging and
connecting to the mains power.
Sufficient cooling around the 8341A must be ensured. The
minimum clearance behind, above and on both sides of the
monitor is 50 mm (2 in). If the product is installed in a recess,
the space must be ventilated sufficiently to dissipate the heat.
Mounting And Placing Monitors
Mounting Options
The vibration insulating Isolation Positioner/Decoupler™ (Iso-
Pod™) table stand allows tilting of the monitor. The stand

spring can be attached to three mounting points on the 8341A
enclosure, allowing the Iso-Pod to be used on one vertical
and two horizontal positions. With horizontal positioning, the
Iso-Pod must be at it's furthest forward position (See Figure
6).
Aim the monitor so that its acoustic axis points towards the
listening position (see Figure 4). 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 5). When a monitor is placed far away (1.0-2.2 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 the bass output.
Minimize reflections by placing the monitors away from
acoustically reflective surfaces. Acoustic reflections from
objects like desks, cabinets and computer monitors can
cause unwanted coloration and blurring of the sound image.
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 5).
A wide variety of ceiling and wall mounts are available
through your Genelec dealer. Genelec 8341A 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 the M10 thread for
mounting the monitor on a microphone stand. Monitor stands
typically have an incompatible 3/8 in UNC thread. Consult the
Genelec Accessories Catalogue at www.genelec.com or your
local distributor/dealer for information.
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.
In situations requiring deeper fundamental response or
multichannel
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.
There are no user serviceable parts inside the monitor.
