System
The bi-amplified GENELEC HT206 and
HT208 are two way active speakers
designed for high quality Home Theater
systems.
Designed as an active speakers, these
units contain drivers, power amplifiers,
active crossover filtering and protection
circuitry. The Directivity Control
Waveguide (DCW) technology used
provides excellent frequency balance
even in difficult acoustic environments.

Drivers
The HT208 has a 210 mm (8") bass
driver and the low frequency response
extends down to 43 Hz (-6dB). The
HT206 has a 170 mm (6
1
/2") driver with
-6dB point at 47 Hz.
The high frequency driver is a 25 mm
(1") (HT208) or a 19 mm (
3
/4") (HT206)
metal dome. The uniform dispersion
control is achieved with the
revolutionary DCW technology
pioneered by Genelec. This has also
resulted in perfect phase and delay
uniformity at the crossover frequency.
The bass and treble drivers are
magnetically shielded on both models.
CrossoverCrossover

Crossover
The amplifier unit contains an active
crossover. This is the ideal method for
dividing the input signal between the
driver units, allowing the overall
response of the system to be optimized
to an extent impossible with a passive
system.
To maintain uniform frequency balance
in differing acoustic environments,
three special calibrated controls are
included in the active crossover
network: treble and bass 'tilt' and bass
'roll-off' switches, which make
adjustments in 2 dB steps (see Fig. 1).

Amplifiers
The amplifier unit is mounted to the
rear of the speaker enclosure. Both the
bass and treble amplifiers on the HT208
produce 120 W of short term power.
The HT206 has a 80 W amplifier for the
bass and 50 W amplifier for the treble
driver. Both units incorporate protection
circuitry for driver overload protection
and amplifier thermal overload
protection. Variable input sensitivity
allows for accurate level matching to
the decoder or preamplifier.

HT208 also features an "autostart"
function. "Autostart" turns off the
amplifier if there is no signal present for
about 5 minutes. When the signal
returns the amplifier switches on
immediately and the speaker functions
normally. This function should be
enabled when the speaker is left turned
on even when not in use; power is
saved when the amplifier is switched
off. An indicator LED on the DCW plate
shows the system status.
"Autostart" can be enabled or disabled
as required by using the dip switch on
the speaker back panel (see fig.4).

2. Installation
Place the loudspeaker in its required
position, taking note of the line of the
listening axis (see figures 2 and 3). To
ensure cooling, there should be a
clearance of more than 4" (10 cm)
between speaker backplate and any
solid surface. Before connecting up,
ensure that the mains switch is off (see
figure 4). Check that the mains voltage
selector is correctly set and that the
appropriate fuse is fitted.

Sound System.
Audio input is made via a 10 kOhm
balanced (XLR) OR unbalanced (RCA)
connector (see fig. 4). If the signal
source has suitable balanced outputs,
we recommend the use the XLR
connector and balanced interconnect
cables due to their better resistance to
interference. Once connection has
been made, the speakers are ready to
be powered-up.
