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.
Mounting and Placing Monitors
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.
Figure 3. The location of the acoustic axis is on the center-
line of the monitor at the given height “h”.
Figure 4. Symmetrical layout and keeping the acoustic
axis clear from obstructions minimizes reflection surfaces
and maintains accurate localisation because reflections are
symmetrical.
