Breaking the rules
There seems to be along-standing tacit agreement among
manufacturers of audio amplifiers as to exactly at which price and
quality level the integrated amplifier must cease to exist and give way
to separate preamplifier and power amplifier components, Many so-
called high end designers refuse to even seriously consider the
notion of an audiophile integrated amplifier.
At Gryphon, our engineers decided to break these unwritten rules
and see what would happen when we applied our skills to pushing
back the performance envelope in a true high end integrated
amplifier.
The Gryphon Tabu AT is the end result of these efforts, making
audiophile performance available at a new level of affordable cost
and minimal complexity.
One step down from no compromise, build-it-now-and-calculate-
the-price-later separate audio amplifiers, the Gryphon Tabu AT
clearly demonstrates the viability of the integrated amplifier as a high
end concept. Because the Gryphon Tabu AT is a properly designed
unit from the ground up, savings from building on a single chassis
do not have significant negative impact on performance and the
advantages of shortening the signal path substantially by eliminating
a number of signal junctions such as sockets, plugs, soldering points
as well as an expensive exposed interconnect are indisputable.
Naturally, the electrical and sonic compatibility of the preamp stage
and power output section are assured, Although this may seem a
trivial point, it is definitely not a foregone conclusion when

attempting to mix and match components from different
manufacturers, or even from the same manufacturer.
A Genuine Gryphon Audio Design
High end manufacturers, daunted by the challenge of
achieving high performance at reduced cost, yet desirous of gaining
a share of the lower high end market, sometimes give up and simply
buy finished designs from outside engineers more experienced in the
area of cost-effectively production. Naturally, this means that the
sonic performance normally associated with the brand name is
entirely absent from their entry level products.
The Gryphon Tabu AT, however, is designed by the very same team
of award-winning engineers responsible for the conceptualization,
exterior design, audio circuit design and final voicing of every single
Gryphon product since the very beginning.
While the vast majority of designers only have access to
commercially available CD's or LP's, the Gryphon Tabu AT is the
result of extensive listening sessions with selections from our exclusive
collection of more than 1,000 first or second generation studio
master tapes from the Golden Age of stereo recording. These tapes
represent the closest approximation to the original live performance,
providing a more reliable reference which allows us to work to a
much higher standard.
Higher Standards
Those familiar with the acclaimed musicality and advanced design
philosophy of Gryphon Audio Designs will instantly recognize the
sound, look and feel of the Gryphon Tabu AT. Careful attention has
been paid to component selection and interaction, circuit design,
PCB layout, grounding, assembly and quality control in every phase
of the design process.
The Gryphon Tabu AT is essentially two independent mono devices
for reduced crosstalk and interchannel interaction.
The short signal path employs extra thick copper traces and an
absolute minimum of wiring. Balanced inputs fully exploit
transmission in the balanced mode for improved immunity to
interference.
The mechanical design of the cabinet and assembly methods are all
carefully calculated to provide an ideal, non-resonant environment
for vibration-sensitive components, through mechanical grounding
and decoupling of the transformers.
For your peace of mind, the Gryphon Tabu AT employs a
comprehensive non-invasive protection system to protect your
amplifier and loudspeakers under the vast majority of situations with
no adverse effect on sonic performance.

Musicality and Practicality
The full-function remote control included with the Gryphon Tabu AT
brings a new level of convenience and functionality to high end
audio. Flexible, modular design allows the option of purchasing the
Tabu AT in a line-only version or with an optional audiophile-grade
phonostage. The phonostage module may also be added at a later
date. The Gryphon Tabu AT is an elegant combination of
outstanding musical performance, ease of use and distinctive
cosmetic design.
USERS GUIDE
Because the Tabu AT is an integrated amplifier, connecting and
using the unit is very straightforward.
Important instructions regarding fuses and balanced connections are
printed on the rear panel of the Tabu AT.
The Tabu AT remote control was chosen because it is a reliable
inexpensive unit. This choice was based on the fact that most
Audiophiles prefer using a multifunction remote control rather than
having a battery of different remote controls for their complete AV
system.
Depending on the type of multi remote control that you hove, your
remote control may learn from the TABU remote control or you may
program your remote control directly by using the TABU data code.
The data code for the TABU remote control is:
DATA CODE FOR
REMOTE CONTROL
Code format, RECS 80 Low voltage.
System address 02
Function Data Code
ON/OFF 01H
MUTE 02H

INPUT down 08H
Please refer to the user guide that came with your multifunction
remote control for further instructions.
UNPACKING Please check that everything is inside the box.
Keep the box in a dry place for eventual future transportation.
INSTALLATION Place the Tabu AT at a location where good ventilation is provided.

Air must be free to circulate around the amplifier.
AC CONNECTION Use only a dedicated AC power cord. Do NOT use loudspeaker
cable or other wire not expressly designed for AC purposes. Avoid
using long extension cords.
Your AC supply must be able to deliver a peak power of 1.100
Watts. The Tabu AT uses 100 Watts at idle.
TABU FUSES Fuse values are printed on the back of the Tabu AT, do only replace
with fuses of same value.
BURN IN / WARM UP
Your Tabu AT has been tested and burned in before delivery,
however it is our experience that the Tabu AT will continue to
improve over the next 100 hours of use.
FRONT PANEL The faceplate lay-out on the Tabu AT is very simple.
The Volume control may be used manually or by remote control.
From left:
Pushbutton 1 is on/off or stand-by.
Pushbuttons 2-6 are line inputs. No. 2 is the balanced input. The
monitor pushbutton allow you to monitor play back from tape
recorder.
When using the remote control you can choose input by the up and
down buttom. Up and down is going from left to right as seen from
the front of the Tabu AT.
REAR PANEL
CONNECTIONS
Not only is the Tabu AT a true dual mono Integrated Amplifier but it
is designed with mirror imaged circuit boards. This makes the rear
panel connections a little unusual compared to ordinary products.
Input 5 Left and Input 5 Right are close together at the center of the
rear panel. All connection are to be made from center and out in
symmetry.
PHONO INPUT
(Optional)
If phono module is installed, your turntable should be connected to
input nr. 5
