When you have decided upon which method of connection you want and positioned the subwoofer (see
the chapter “Positioning Loudspeakers – HELICON S600/S600MK2”), you can commence the exciting
process of adjusting the system. Please note that positioning the subwoofer will have a lot of influence
on its contribution to the overall sound. If for example, the subwoofer is positioned in a corner, the bass
level will be much higher than if it is positioned midway between two corners (due to acoustic loading of
the subwoofer). If using the subwoofer in conjunction with the C200 center loudspeaker, the subwoofer
should be positioned so that the C200 can stand on top of the subwoofer.
The following adjustment methods are recommended to
achieve the best results. Use a piece of music you know
well, and that preferably includes rhythmic bass such as
kettle drums, bass guitar etc.
Start with "VOLUME" and "CROSSOVER" in the middle
of the dial (12 o’clock). Turn the "PHASE" switch to posi
-
tion 180°, and "POWER" to the "ON" position.
ADJUSTMENT OF HELICON S600/S600MK2
ENGLISH
VOLUME ADJUSTMENT
Adjust the volume of the subwoofer so that the bass matches the level of the front speakers. You
should be able to appreciate the subwoofer’s contribution to the sound, without it ever being over-
powering. Bass must be tight and accurate, so that the subwoofer reproduces the exact amount of
bass present in the music/soundtrack, no more and no less. If installing the subwoofer in a surround
sound system, it is practical to select a fixed level on the subwoofer and adjust subwoofer output us
-
ing the surround amplifier's set-up function. If bass levels are set too high, distortion will reduce the
quality of your listening experience. Please note that the position of the subwoofer will have major
influence on its sonic contribution.
ADJUSTING THE CROSSOVER FREQUENCY
Once the volume level is adjusted, you can start the equally important adjustment of the overlap between
the front loudspeakers and the subwoofer. To do so, adjust up and down using "CROSSOVER" until you
can hear that the bass is even and with no drop-out. You may have to adjust the volume again.
SELECTING AUTO FUNCTION
The "AUTO" function puts the subwoofer into standby after approx. 10 minutes with no signal
received at the inputs. When a signal is present again on one of the inputs, the built-in subwoofer
amplifier powers up automatically. The "POWER" button is the main on/off switch. We recommend
switching off the system when it is not to be used for long periods. When connecting or changing
connections, always disconnect the mains electricity.
er exclusively reproducing the low frequencies. From the output socket “LINE OUT - LEFT” a highpass
filtered signal may be tapped, as when using a stereo connection. Please note that there is no signal
available on the “LINE OUT - RIGHT” socket.
Connecting to a Lowpass Filtered Mono Signal
When using the subwoofer with a surround amplifier or
other equipment with access to a filtered mono output
for subwoofer use, it is advantageous to connect this
signal to the subwoofer´s input marked “LFE”. When the
subwoofer is connected via “LFE“, the signal bypasses the
crossover network and goes directly to the amplifier. In
this setup, there is no signal available at the output “LINE
OUT”. Any adjustment of the crossover frequency takes
place elsewhere in the system, typically the surround
processor/amplifier. Please follow the instructions provided in that component’s manual. When using
the “LFE” input, the level and phase controls of the S600 are still active and these should be adjusted
as recommended in the section concerning adjustments.

SETTING PHASE
Try both settings – if necessary combined with new adjustment of volume and crossover frequency. In
any event, it is a good idea to listen to the system for a few days before making any final adjustments.
Using the same setting for surround sound and stereo does not always achieve the best results. It is
therefore a good idea to note the setup you prefer for surround sound and stereo setups.
