Introduction &
a little background
Thank you for choosing a GamuT product. All GamuT products are made for you to
enjoy and live with for many years to come.
With the PHi series we begin a new chapter in pursuing the highest sonic performance possible, where the natural number PHi (1.618) has played an important role
in creating the resonance controlling groove in the cabinet, as well as designing the
exterior looks.These new solutions along with our DC coupled midrange and NRLI
network technology and our new self locking & easily adjustable feets, present a
new and unique solution in bringing optimum sound quality into your living room.
Unpacking
Setting up
– simple & fast
Toe-in
Your Phi´s comes with a pair of GamuT “stretch to t” mounting gloves.
Use these gloves or take off your rings and watches to avoid scratching the delicate surfaces. All Phi are fully assembled and tested at the factory, so no parts
needs mounting. All Phi are delivered in white cotton bags for protection. All is
ready for use when the protective bag is removed. Phi5 & Phi7 both comes with
our new non resonant feet. Remove the tape that holds the feet against the bottom,
and fold the front feets forward and the rear feets backwards.
The Phi LCR comes with an extra front cover to be mounted if the LCR is used in
its vertical position, either as a stereo speaker or rear speaker.
Speakers are acoustic instruments working with your room.
Placement of the speaker and the listening position will always have an inuence
on the nal sound quality, and following the minimum recommendations will assure
you a good overall sound quality.
Minimum recommendations: Position your speaker at a minimum of 70 cm from
the side wall (measured from the tweeter position), and at a minimum of 60cm
from the back wall, also measured from the tweeter position.
Point the speakers straight, and tilt the speakers so that the tweeter axis aims approximately at your ears.
We recommend no toe-in, at least as a starting option.
This results in a listening angle of app. 20 degrees off axis to the listener, in an
optimum listening setup.
Why toe-in: The maximum tweeter level is on axis. The more off axis you listen
the lower the high frequency level will be in the listening position. Use toe-in to
adjust/increase the high frequency level, and to reduce the high frequencies being
reected off the side walls.

Optimizing the sound
- running in
Hold the speaker in its vertical position with one hand, and use your other hand to
tighten all 4 knobs as hard as you can by hand. The special geometric design of
the feet will now use gravity and friction to lock the adjusting knob when sufcient
force is on the foot. If you need to tilt the speaker front/back or sideways, push
the speaker to its desired position and again tighten all 4 knobs. You may need to
adjust the tilt of the speaker to t your seating height. See the instructions later.
Single wire connection:
Connect the positive cable to one of the red terminals, and the negative wire to
the black terminal.
Bi-wire connection:
Unscrew all 4 nuts from the terminals and remove the two brackets. Connect one
pair of cables to the lower input, positive to red (right hand side), negative to the
black terminal, and one pair to the upper pair of terminals.
Speakers are Electro-mechanical devices. They need a run-in period to reach their
optimum performance level. We suggest letting the speakers run at high Levels for
at least 6 hours before judging the sound quality.
The process of running in can take up to 200 hours of music playing at high levels,
and agening of the materials as well will also play an important role in reaching the
maximum performance. Expect your speakers to reach maximum performance in
approximately 6 months time.

Calculating the optimum
position
The correct tilt is where the tweeter axis is aiming directly towards your ears.
Why tilting: The tilt of the cabinet determines the timing between the tweeter and
the mid range/woofers. Tilting the speaker backwards delays the tweeter, where
a forward tilt does the opposite. Tilting the speakers forward gives a brighter
character with more emphasis on high frequency transients, where a backwards
tilt gives less focus on the high frequency transients.

Use the 2 diagrams below to determine the best setup positions for your speakers
and your listening position. As can be seen there are quite a few options.
Choose the ones that exceeds the 60 cm distance to the back wall and 70 cm to
the side walls. Remember all measures are taken from the tweeter position.

Care & Maintenance - keep the good sound coming
All connections, even very good ones will slowly deteriorate over time. A good choice is to keep the
connections clean by using a clean cloth & spirit.
The knobs on the terminals will over time loosen as the cable gives in to the pressure from the knob,
tighten the connections in between.
Keep the looks
Clean the lacquered and cloth surfaces using a clean damp cloth with a light detergent or a soft brush.
Be careful not to deform the diaphragms of the drive units while cleaning. Bending or deforming a
diaphragm will compromise the performance and durability of your speaker.
Be a master of sound trimming.
