General Description
The Genelec 7040A is a very compact active
subwoofer for reproducing low frequencies.
The 7040A extends the bass reproduction
of Genelec 8010, 8020 and M030 active
monitors for stereo applications. Using the
7040A extends their frequency responses
down to 30 Hz (-6 dB).
Driver
The 7040A contains one 165 mm (6.5
in) magnetically shielded driver, housed
in Genelec Laminar Spiral EnclosureTM
(LSE™).
Bass Management
Balanced XLR connectors are used for the
audio inputs and outputs. There are two
input connectors and two outputs.
The bass management unit in the 7040A
subwoofer splits the input into low and
high frequency components at 85 Hz.
Frequencies below 85 Hz are reproduced
by the subwoofer. Frequencies above 85
Hz are directed via the subwoofer's output
connectors to the main monitors. The
subwoofer's outputs have the same level as
the inputs.
The subwoofer sensitivity can be adjusted
from +12 to -6 dBu to match the subwoofer
sound level easily with different monitors.
Two "BASS ROLL-OFF" switches provide
bass response adjustment to compensate
for the acoustical environment in three 2
dB steps. Two switches allow alignment
of subwoofer phase with the monitors.
The phase can be adjusted in 90 degree
increments between 0° and -270°.
Amplier
A Class D power amplifier produces 50
W output power with very low THD and
IM distortions. Driver overload protection
is included in the amplifier circuitry. The
a m p l i f i er a l s o i n c or p o r a t es t h e r m a l
overload and short circuit protections.
The power supply accepts mains voltages
from 100 to 240 VAC.
ISS™ Autostart
The 7040A is equipped with Intelligent
Si g na l Se n s i n g T M (ISS™) aut om a t i c
start funct ion. ISS turns t he amplifier
to standby mode if no input signal has
been detected for one hour. The power
consumption in standby mode is less
than 0.5 watts. Playback automatically
resumes once an input signal is detected.
There is a slight delay in the automatic
powering up. In those environments where
the 7040A is required to be on all of the
time, the ISS function can be disabled
by setting the “ISS DISABLE” switch to
the “ON” position. Then the subwoofer
is c ont i n u ou s ly p owered a n d can be
turned off using the power switch on the
connector panel. The default position
from the factory is with "ISS DISABLE" in
the OFF position.
Installation
The subwoofer is supplied with a mains
cable and this operating manual. After
unpac king i nspec t the subwoofer for
possible damage in transport . Ensure
that the subwoofer and the monitors are
powered off before connecting cables.
