A Message from Genesis
The transparency, detail retrieval, macro- and micro-dynamics, and
wide frequency extension of Genesis loudspeakers place great
demands on the quality of amplification. Hence, to match the Genesis
loudspeakers, the Genesis Reference Series of amplifiers was
created as the finest musical amplifiers available.
The Genesis Reference Amplifier, together with a pair of Genesis
loudspeakers, will give your entire music collection a whole new life.
In a well set-up system, it is capable of transporting the musical
performance into your room. The hiss and hum normally associated
with vacuum tubes are completely absent, while retaining the
richness and rightness of the best of this genre of amplifiers.
Transistor etch and harshness are completely absent, while retaining
the slam and control of the best of solid-state.
During development, we benchmarked against the best cost-noobject amplifiers – both solid-state and vacuum tube. While we were
intent on developing a value-priced product, quality has not been
scaled down. Hand-selected, precisely matched components are
used throughout: copper-core silver wire with Teflon insulation is used
in the entire signal and power path. Each and every unit is completely
hand-assembled in the USA, and burned-in before final testing and
measurement.
The result of all this obsessive attention to detail is a fabulously
musical power amplifier capable of driving almost any loudspeaker in
the world. The state of the environment is also taken care of with
extremely high efficiency, instant warm up, and a simple, functional,
and elegant design.
Before using this unit, please take the time to carefully review the
safety instructions and operating information contained in this
Owner’s Manual. Becoming familiar with your new amplifier and the
correct operating procedures will help assure you of safe usage,
reliable operation, and maximum musical enjoyment.

Some of the inspiration for the GR-Amp came from the sci-fi movies “Silent
Running” and “Max Headroom: 20 Minutes into the Future”.

Set-up and Safety Information
Now that you have your new amplifier, we realize that you can't wait to hook
it up and start playing! However, please read this set-up guide and safety
information before you proceed.
Unpacking and Setting Up
The amplifier is likely to come in parts – the amplifier module, an acoustic
suspension, and a power transformer (an auxiliary power supply upgrade
called the Maximum Dynamic Headroom Reservoir is also available) unless
your dealer has assembled it for you. So, some assembly may be needed
before you can start playing. It is important that this product is never used
near water or sources of water. Avoid bathrooms, washbowls, kitchen sinks,
swimming pools, etc.
Carefully remove the various parts of the amplifier package from the cartons
and unwrap it. The suspension system will need to be assembled to the
amplifier chassis. You will use the hex key and four hex screws supplied to
do this.
Place the amplifier chassis top down on a clean surface.
Place the suspension frame on the shock absorbers so that
the holes of the shock absorbers are aligned with the
matching holes on the frame. The suspension frame “points”
forwards so that the tip of the triangle faces to the front of
the amplifier, and the round hole is in the front.
Use the hex screws and the supplied hex key to secure the
suspension frame to the shock absorbers. Do not overtighten the screws.
Turn the amplifier over, screw in the steel spike bolts into
the threaded holes in each corner of the suspension frame.
Screw them in so that the spikes protrude by about a third of
an inch (8mm) from the bottom of the frame and no more.
The Acoustic Suspension will allow the amplifier to be
placed directly on the floor, or on any piece of furniture or
equipment rack. The amplifier should not be subject to
vibration of any sort. Do not place them directly in front of, or
on top of your loudspeakers. Despite the vibration and
resonance control measures already taken in the Genesis
Reference Amplifier, we are not able to completely eliminate
all incoming vibration.

Once you decide on the placement of the amplifier module, and connect the
power transformer using the supplied Power Umbilical, locate the power
transformer module as far away from the listener as possible. The Power
Umbilical will only go in one way so the assembly should be obvious. Align
the plugs to the like-colored sockets, insert and twist until the lock “clicks”.
If you have the optional Maximum Dynamic Headroom Reservoir (MDHR),
place that on top of the amplifier module
2
, and connect the two using the
short Power Umbilical supplied with the MDHR. Then, connect the power
transformer module to the MDHR.
Before you plug the power cord in the power transformer, please make
sure that you have the power transformer with the proper voltage for
the country you are in. Taiwan, Japan and North America will require the
115V version. Most European countries and other Asian countries will
require the 230V version. Also, make sure that you have the appropriate
power transformer for the amplifier model that you have.
Connect the loudspeakers to the 5-way binding posts using good quality
loudspeaker cables, and the appropriate RCA or XLR interconnects to the
pre-amplifier.
Safety Information
1. Never try to disassemble the amplifier as you may be exposed
to dangerous voltages. Even after turning the amplifier off and
unplugging it from the wall socket, it will retain a lethal electrical
charge for a very long time. There is huge energy storage in the
power supply capacitors (and even more so in the MDHR!!).
2. Do not attempt to modify the amplifier. The device has been
tested and adjusted for optimal operation and should give you
years of trouble-free service.
3. Do not connect/disconnect the power supply and power
transformer from the amplifier module without turning the
amplifier off first.
2
Note that the rubber feet of the MDHR may mark the top of the amplifier
module, but this is easily cleaned off using rubbing alcohol or “Goof Off”.
However, please note that the placement and material of the rubber feet will
serve to further damp the top plate of the amplifier module. Do not be
tempted to use cones or other forms of isolation between the MDHR and the
amplifier module. The top of the amplifier chassis holds the signal path.
