Coarse phase adjustment
method
Configure the processor so that the main
speakers (L, C, R) are set to “small” and
check the subwoofer crossover frequency
setting on your processor. This setting may
be either fixed or variable, consult the operat-
ing manual of your processor.

Using multiple subwoofers
The HTS6 is equipped with a “LINK OUT”
connector to provide an easy way of coupling
two or more subwoofers together in high
SPL applications. Connect a XLR cable from
the “LINK OUT” connector of the “master”
HTS6 to which the main monitor channels
are connected, to the “XLR IN” connector of
the other, “slave” subwoofer.

HTS6 to which the main monitor channels
are connected, to the “XLR IN” connector of
the other, “slave” subwoofer.
When two subwoofers connected in this
way are positioned close to one another,
bass level increases by 6 dB. Three
subwoofers give an bass SPL increase of 9,5
dB and four subwoofers 12 dB compared to
a single subwoofer. Adjust the sensitivity con-
trol of all subwoofers in the group to match
the SPL level with the main speakersystem.
Note that the sensitivity setting must be the
same on all subwoofers.

Autostart and remote control
The HTS6 is equipped with an “AUTOSTART”
function, which automatically turns the ampli-
fier to “STANDBY” mode if an input signal has
not been detected for approximately five min-
utes, and back to “ON” mode when the signal
returns. The function can be deactivated by
turning the “AUTOSTART” dip switch to “OFF”.
A two-colour LED on the connector panel indi-
cates the amplifier status: green for “ON” and
yellow for “STANDBY”.

A two-colour LED on the connector panel indi-

The amplifier mode can also be switched
by a remote control unit connected to the
respective inputs on the amplifier. Two pairs
of connectors are provided, 1 and 2 for a
12 V DC type remote control, and 3 and 4
for an external switch or relay type control.
Do not connect two remote controls to the
