General description
5051A Active Subwoofer
The Genelec 5051A is a very compact
active subwoofer designed to complement
up to five Genelec 6010A or 8020B active
loudspeakers or a pair of the slightly bigger
8030A’s. Linked together two 5051A’s can
also be used with a pair of 8040A’s. The
5051A extends the system’s bass response
down to 27 Hz and integrates perfectly with
the main loudspeakers in any environment.
The playback level for the whole system
is conveniently controlled by the wireless
volume control provided with the subwoofer.
A wired volume control is available as an
option.
The 5051A has an integrated bass man-
agement for the five main channels which
directs the frequencies below 85 Hz to the
subwoofer and higher frequencies through
the output connectors to the main loudspeak-
ers.
Installation
Before connecting the audio signals, ensure
that all equipment is switched off.
Pull out the battery insulating strip from
the underside of the remote control as
shown in figure 1. This strip insulates the
battery from the contacts on the remote
control during shipping and the remote
control does not function before it is
removed.
The subwoofer is equipped with six RCA
signal inputs (L, R, C, LS, RS and LFE/LINK
IN) and two balanced XLR inputs (LEFT,
RIGHT). These allow connecting the 5051A
to a variety of line level audio sources with
either unbalanced RCA or balanced XLR
type audio connectors. Suitable sources are
preamplifiers, computer sound cards, port-
able audio players, “PRE OUT” connectors
on a Home Theater receiver, etc.
The output section of the subwoofer con-
tains corresponding L, R, C, LS and RS RCA
connectors for the main loudspeakers, a
LINK OUT RCA connector for linking multiple
subwoofers together and two balanced male
XLR connectors (LEFT, RIGHT).
The L and R RCA inputs and outputs are
working in parallel with LEFT and RIGHT
XLR inputs and outputs.
As the 5051A contains its own amplifier,
no separate power amplifier is needed. Never
connect the 5051A to the loudspeaker out-
puts of a power amplifier, integrated amplifier
or receiver.
Connecting a stereo system
Connect the audio signal cables from your
source to the corresponding input connec-
tors. The 5051A offers both balanced and
unbalanced signal routes. For stereo sig-
nals, use either the LEFT and RIGHT XLR
inputs or the L and R RCA inputs. Next, con-
