A Message from Genesis
Congratulations! You are now the owner of one of the finest
loudspeaker systems in the world. Based on technologies developed
and evolved over the past four decades, the Genesis 5.3 is a small
4-ft tall floor-standing loudspeaker, and yet it delivers some of the
dynamics, imaging and soundstage of our largest 7-foot tall
reference Genesis 1.1 product.
The G5 loudspeaker system was created for the music lover living in
smaller environments. It is designed to reproduce music (and film) at
live listening levels with virtually no restrictions on dynamic range,
frequency response, or imaging capabilities. This is what we mean
by
absolute fidelity™, the ability to reproduce the musical event
faithfully, as was intended by the performer, or the film-maker.
Standing 44 inches tall, and only 11 inches wide, the Genesis 5 is a
diminutive giant. By means of an active servo bass, response down
to 18Hz is achieved, and the full range and impact of a symphony
orchestra or a rock band can be reproduced.
With adjustable tweeter, midrange, and bass controls, the G5 can be
tuned into any room. The adjustable acoustic platform also allows
the G5 to be ideally sited on all types of flooring – from the typical
joist-suspended carpet-covered floorboards in the USA, to uneven
terracotta tiles in an Italian villa, and flagstones on an English
mansion.
Please read this Owners Manual and Set-up Guide to get the
maximum enjoyment out of your purchase. Also, if you have access
to the Internet, please check back at our website often. The address
is www.genesisloudspeakers.com
. We will put the latest updates,
tips and tricks, and support for our owners on our website.
Please write the serial number and purchase details of your
Genesis 5.3 here for future reference.

A Quick Start Set-up Guide
Now that you have your new Genesis 5.3 loudspeaker system, we
realize that you can’t wait to hook it up and start playing! However,
please read this quick set up guide (even if your dealer is setting it
up for you!) before you proceed.
Unpacking
Your loudspeakers will come to you in two large shipping cartons.
The G5’s weigh over 145lbs (66kgs) each, so we suggest a
minimum of two strong people to move the speakers around. We
will not be held liable for damage (to either the speakers or your
backs!) during unpacking and setting up if you ignore this basic
advice. Please collapse and keep your packaging in case you need
to ship the speakers.
Room Placement
A good starting position for your G5 is about 20% the way into the
room as measured from the front wall (the wall you look at as you
are seated listening to the speakers), six feet (~2m) apart, and firing
straight ahead with no toe-in. You will want to sit ten to twelve feet
(3m – 4m) away from the speakers, and have at least 24inches
(60cm) from the back of the speaker to the wall.
Typical room placement: Place speakers about 20% of the
way into the room and 10 to 12 feet from the listeners

Set-up Guide
Positioning
A good starting position for the Genesis 5 is about 20% of the way
into the room as measured from the front wall (the wall you look at
as you are seated listening to the speakers). If you are in a smaller
room, try to have at least 24 inches (60 cm) of space from the back
of the speaker to the front wall. You may have to sit closer to the
back wall, or sit closer to the speakers, but try to keep at least 24
inches of space behind the speakers.
Start with the speakers six feet apart, and not toed-in. You will want
to sit at least 10 feet (3 metres) away from the speakers for proper
integration of the drivers. We will experiment with moving the
speakers around, and toeing them in later.
Power Connections
There are two connections you will need
to make to the G5. First, the power cord
for the built-in amplifier will need to be
plugged into a power socket. A 10-foot
power cord is included with your speakers
for this purpose. We do not recommend
using an extension cord for the G5 due to
the high power demands of the 500W
amplifier. However, if you MUST use an
extension cord, use an extremely heavy
duty one. The amplifier can draw up to 10
amps at 115v, hence make sure that the
extension cord is adequately rated.
ver 1.0
Before you plug the power cord in, please
make sure that the voltage selector is set
to the proper voltage. Japan and North
America will require the 115v setting.
Most European countries and other Asian
countries will require 230v. The fuse is a
5amp 250v slow blow irregardless of
voltage used.
There is an on/off switch for the power
amplifier. This switch should always be
left on. We recommend that you plug the
4444
~ДлздмнЙ=СбЗЙдбну™
G5 into an unswitched outlet, or a switched outlet that can always be
left ON.
The built-in amplifier has an auto-sensing circuit that will put the
amplifier into stand-by when there is no music being played for
around 25 minutes. It will immediately switch the amplifier on if there
is a signal sensed.
Hence, leave the amplifier on unless you will not be using the
system for an extended period of time (like a month-long vacation).
When you return, the system may sometimes encounter what we
call a cold-start problem. After the amplifier has been turned off for
an extended period of time, it may squeal when first turned on.
Leave the amp squealing for 15 seconds (it won’t hurt the
loudspeaker). Then turn it off. Wait another 15 seconds, and turn it
on again. If it stops squealing, well and good. If not, leave squealing
for a bit longer this time (an additional 15 seconds), and turn it off.
Repeat until the loudspeaker stops squealing. It should take no more
than two to three times before the amplifier warms up and stops
squealing.
Source Input Connections
Connect the output of your power amplifier to the High Level Input
binding posts using a high-quality loudspeaker cable. Make sure that
you have the correct polarity connected for both speakers – the plus
or positive (red) terminal on the G5 should be connected to the plus,
positive, or red terminal on your power amplifier.
The Bass Input selector switch should be in the up or high-level
position – pointing to the inputs being used. This is the
recommended hook-up, both sonically and for convenience.
Nevertheless, you may wish to connect the bass section of the G5
directly to your preamplifier instead. If you know that your power
amplifier may be deficient in the bass, or does not have a
response flat down to 18Hz (such as some Single-ended Triode
amplifiers).
If you use the low-level inputs for the servo-bass of the G5, you
will need to check for the phase correctness of your power
amplifier. If your power amplifier inverts phase, you will need to
ver 1.0
5555
~ДлздмнЙ=СбЗЙдбну™
invert the high-level inputs when the bass section of the G5 is
driven by the preamplifier.
If you do this, use a good quality balanced interconnect cable to
connect the balanced output of your preamplifier to the preamp
level input XLR connector, or the single-ended output of your
preamplifier to the preamp level input RCA connector on the back
plate of the G5.
While using this connection, switch the Bass Input Selector to the
down/line-level position. This will bypass the high-level input from
the servo amp, and the bass input is taken directly from the lowlevel inputs.
Do NOT connect both the XLR and RCA inputs at the same time.
If you are planning to use long runs (over 10 feet or 3m) of
interconnect to connect the line-level inputs of your G5 to your
preamplifier, we recommend that you use a balanced connection.
The Acoustic Platform
The G5 sits on a suspension
system designed to allow the
loudspeaker to perform at its
optimum. It consists of three
elements – neoprene decouplers, a
tuned skeletal frame, and stainless
steel spikes. The system holds the
loudspeaker firmly, and yet isolates
it from the floor on which it sits.
At this point, use the plinth as it
comes. Position the speakers, and
then use your fingers to screw the
spikes down to raise the speaker off
the floor so that it only rests on the
spikes and no part of the frame touches the floor. Make sure the
speaker is level, and then tighten the lock nuts under the frame to
secure the spikes.
We will explore different options later when we fine-tune the system.

Controls
There are a total of five control knobs in two rows on the back plate
of the Genesis 5 loudspeaker.
The upper left knob on the back plate marked “Tweeter” is a
volume control for the front tweeter. Turning this control
clockwise will increase the level of the
front tweeter. Use this control if you
need a bit more treble or to increase
the apparent space of the
soundstage. Start with this control at
the 12 o'clock position. There is about
a one dB range for this control. The
12 o’clock straight up position is
nominal for all controls.
The upper right knob marked “Midrange”is used to adjust the
level of the midrange. Again, start this at the 12 o’clock position.
Turning the control anti-clockwise (or counter-clockwise) will
make the midrange sound more laid-back, and turning it
clockwise will make the midrange more forward. There is about a
one-and-a-half dB range for this control.
The knob on the middle of the lower
row of knobs marked “Bass Gain”
controls the volume of the built-in bass
servo amplifier. Begin with this control
at 6 (the 12 o’clock position). Adjusting
the gain higher will make the
loudspeaker sound “fuller” and more
bass-heavy.
The knob on the middle right marked “Low Pass” controls how
high the woofer will play. At the extreme low of 71Hz, the woofer
will play up to 71Hz, and then begin rolling off, or reducing its
volume, above this frequency. The recommended beginning
position for this control is 90Hz. Adjusting the crossover point up
will make the G5 sound warmer and fuller in the mid-bass.
The knob on the left marked “LFE Gain” is used for home theatre
applications, so ignore it for the time being.
