Genelec G Four, Руководство по эксплуатации

Страница: 2 / 12

General description
Genelec G Three and G Four are two way
active loudspeakers designed to produce broad
bandwidth sound with high output and low col-
oration.
Positioning the loudspeaker
Each loudspeaker is supplied with a built-in
amplifier unit, mains cable and an operating
manual. After unpacking, place the loudspeak-
ers in their required listening positions, pointing
them to the center of the listening area. If pos-
sible, place the listening position to the central
line of the room and the loudspeakers at equal
distance from the side walls.
Connections
Before connecting up, ensure that the power
switches on the loudspeakers and the signal
source are set to OFF. The power switches of
the G Three and G Four are located on the back
panel of the loudspeaker. Do not connect the
loudspeaker to an unearthed mains supply or
using an unearthed mains cable.
Audio input is via a 10 kOhm balanced female
XLR connector or unbalanced RCA connector.
Only line level audio signal from a preamplifier,
computer sound card or similar signal source
can be connected, never a high power signal
from the speaker terminals of a power amplifier.
It is possible to connect two audio sources to
the loudspeakers at the same time using both
connectors, as long as only one source is used
at a time.
Once the connections have been made, the
loudspeakers are ready to be switched on.
Autostart function
Both loudspeaker models have a power switch
on the back panel. Set this switch to “OFF”
when the loudspeakers are left unused for sev-
eral days or when connecting or disconnecting
any cables in the system.
When the switch is set to “ON”, the signal
sensing Autostart function of the loudspeakers
powers them up when playback begins. Auto-
matic powering down of the loudspeakers hap-
pens one hour after the playback has ended
and the loudspeakers go to standby mode. The
power consumption in standby mode is less
than 0.5 watts. The loudspeaker will automati-
cally and rapidly start once an input signal is
detected from the source.
Setting the playback level
The playback level of the G Three and G Four
has two basic settings, normal and +10 dB. The
normal setting is factory default and the +10 dB
setting can be selected by turning the “LEVEL
+10 dB” switch on the back panel to “1”. This
makes the loudspeakers play louder, which is
useful if the signal level is low.
Switching off the power
indicator LED
The power indicator LED can be switched off
by turning the “LED OFF” switch on the back
panel to “1”.
Setting the tone controls
The frequency response of Genelec G Three
and G Four can be adjusted to match the
acoustic environment by setting the tone con-
trol switches on the rear panel. The controls
are “Tabletop”, “Treble”, “Bass” and “Low Bass”.
