General description
Genelec HTS6 is a powerful active subwoofer
designed specially for high quality digital 5.1
channel Home Theater systems. Its 19 to
120 Hz (± 3 dB) frequency range and 124
dB sound pressure output capability are suf-
ficient to handle the most demanding high
SPL applications.
High quality XLR and RCA line level input
connectors and adjustable input sensitiv-
ity provide easy connection to all types of
decoders. Bass roll-off rate and crossover
phase can be adjusted to suit different
acoustical environments and subwoofer
positioning. A “LINK OUT” connector allows
coupling two or more subwoofers together
when very high sound pressure levels are
required. The amplifiers are equipped with
an “AUTOSTART” function for automatic
switching between “STANDBY” and “ON”
modes. Connectors for remote controlled
power “ON/STANDBY” switches are also
provided.
Installation
Each subwoofer is supplied with a mains
cable and an operating manual. Once
unpacked, place the subwoofer in a suitable
location (For more details see the ‘Position-
ing’ section).
Before connecting the audio signals,
ensure that all equipment are switched off.
Check that the subwoofer voltage selector
switch is set to the correct voltage. Audio
input to the subwoofer can be made via
balanced XLR or unbalanced RCA connec-
tor. We recommend the use of balanced
cables and connectors due to their better
noise immunity. Do not use both inputs at
the same time.
The “LINK OUT” connector can be used for
daisy-chaining several subwoofers together
when high SPL is required. Simply connect
a balanced XLR cable from the “LINK OUT”
connector to the “XLR INPUT” connector of
the next subwoofer. See section “Using mul-
tiple subwoofers”.
Once all connections have been made, the
subwoofer and main speakers are ready to
be powered up.
Positioning in the room
The placement of the subwoofer in the room
affects the overall frequency response and
sound level of the system dramatically, as at
low frequencies the effects of the room are
strong. Even a slight change in the subwoof-
er's location can make a marked difference
in the frequency balance and often patient
and methodical experimentation and testing
is needed to find the optimum placement.
The placement will affect the phase dif-
ference between the main monitors and the
subwoofer, and also the bass roll-off rate.
These effects can be compensated by the
use of the controls in the amplifier unit; but
we recommend that at first you leave the
switches untouched and concentrate on find-
ing the position where the subwoofer gives
the smoothest response, and only then use
the controls to fine-tune the balance and
phase alignment between the subwoofer and
the main speakers.
To begin with, place the subwoofer slightly
offset from the center of the front wall.
The recommended distance to the wall is
less than 90 cm / 36" measured from the
subwoofer's drivers. This position gives
increased acoustic loading (and SPL) due to
the proximity of the front wall and floor. Can-
cellations from the front wall and floor are
also avoided. In a multichannel system the
main speakers should ideally be positioned
