PHIIOSOPHY
For the past twelve years, Scientific Âudio Electronics,
has been designing, developing, and manufacturing
a unique line of high enil components and accessories.
Utilizing their full production capabilities with a
completely mechanized metal fabrication planq ultra-
clean assembly lines and elaboratequality conrrol facilities,
SAE has been able to produce a line of products with
incomparable quality and integrity.
The originat Sr{E line included a power amplifier
rnd a.preamplifier. The followingL2 years has seen
ir{E successfully broaden that first line of amps and
Dreamps as well as develop a long list of now standard high
iiaeüry components including the first graphic equalizer,
rhe fiist digital readour FM runer, the first parametric
:qualizer, and the first impulse noise reduction system.
Recently, SAE has extended this engineering
tuperiority to the SAE TWO line. Each SAE T\üøO product
reilects the expertise long associated with the SA,E name.
By utilizing rhe efficiency of Japanese manufacturing for
this special line, SAE's engineering preeminence has now
been brought to markets previously unattainable.
connE(Tlons
All audio signal connections should be made with
high qualiq' co-axial audio cables. 'Jühenever rear panel
coãne&ions are being made, the T14 and all associated
cornponents should be switched off.
OUTPUT - Using the high quality stereocableprovided,
connect the OUTPUT LEFT and OUTPUT RIGHT jacks
of your T14 to the appropriate inputs marked "tuner" or
"aux" on your control amplifier or preamplifier.
Á.NTENNA - Once che above connections have been
made, rhe unit is operable; however, both rhe AM and the
FM antennas play a critical role in the overall quality of
reception and we srongly suggest that you take the time
ro adjust them correctly.
FM Antenna - Your T14 is provided wirh a folded
dipole antenna. Before the unit is plugged in, connect this
antenna to the terminals marked "300 Ohms" on the rear
of your tuner. Once the T14 has been plugged in, switched
on and tuned to a desired FM station, adjust the dipole
antenna by moving it around to obtain the best quality
signal from thar particular station. Âs you tune from station
to station, you may need to reorient rhis antenna-
.Although basic, the folded dipole is an extremely
sensitive antenna which allows for the reception of a large
number of available FM stations with your tuner. Should
you find that the dipole is not adequate for y-our receprion
needs, please contact your dealer to obtain further
informãtion about the variety of antennas that will provide
the performance characteristics your require-
You may find in your listening areas that many
stations tend to have a harsh high end where the "s's"
and "t's" sound distorted. This phenomenon is a result of
the runer receiving both direct and delayed signals from
the station. The delayed signals are reflections off of
buildings, mountains and even passing aircraft. To correct

this.condition, it may be necessary to obtain a much more
directional antenna than the dipole. This type of antenna
will permit you to single out the strongest signal for
reception and ensure that the delayed signals will not
inrerfere with the sound quality of your tuner.
Antennas used with FM and TV receivers fall into
rwo basic categories: those rhat reguire 300 Ohm
termination, and rhose requiring 75 Ohm terrnination.
The T14 provides input terminals for either of rhese
systems. Thej cable used in a 300 Ohm sysrem is usually
denoted by a flat appearance and somerimes in irs highest
quality form is available with rwo inner conducrors
and'a shielded ground.
The 75 Ohm termination system is usually
characterized by a round cable (co-axial). I7hen a 75 Ohm
system is used the ends should be prepared so that the
center lead prorudes from the surrounding shielding
and insulation and the metal shielding imelf should
protrude from the outer insulation. This will allow it to be
used with the 75 Ohm terminals on the back of the T14.
This sBtup is described in Figure A.
.AM - The T14 comes with a movable ferrite core antenna
for ÂM reception. This is the bar rhat protrudes from
the rear of the T14. Simply moving it away from the unit
will provide extremely high quality AM reception. Should
you find in your signal area that even with this highly
sensitive bar antenna, you are not receiving adequate AM
reception, you may make your ov¡n AM antenna. This is
accomplished by taking one end of a single insulated wire
and running it to the highest spot on your rooftop and
connecting to EXT AM terminal. Running another
insulated wire from the ground terminal and attaching it
to a good ground such as the center screw on your AC outler
or a water pipe may also be helpful.
AC CONNECTIONS - S7irh the power switch in
rhe off position, plug the line cord into any outlet
furnishing 105 to 125 Volts, 50 to 60 Hz.

OPERRTION OT CONTROLS
AM - This button selects the AM mode on the Tl4.
FM Auto - This selects rhe FM mode. SØhen stations
are tuned in rhis mode, the T14 automatically switches
to stereo when the stereo pilot signal is being broadcaSt
by the station. Otherwise the tuner will receive only mono.
FM Mono - In this mode the tuner will receive all FM
stations in moóo (Whether broadcast in mono or 5tereo).
Hi-Blend - FM Stereo signal has a unique ProPerry in that
the majority of noise is out-of-phase. This blend switch
reduces the high frequency separation between the left
and right channels and by doing so reduces the noise
without sacrificing fidelity.
FM Mute - The T14 provides a muting circuit to reduce
interstation noise which occurs as you tune from station
9
:.:
,:: ..,:
.,:t

to st-ation on FM. If you are searching for an extremely
low level signal, the mute can be defeared by releasing
the butrcn to its out position. The sensitivity of this muring
circuit is adjustable by a rear panel control. This control
should be set so as not to mute the weakest station
you intend to listen to.
Tuning - The T14 empþs a uniquedigimlly synthesized
tuninglystem. The heart of the system is a Quartz
Referãnce Digital C-ounter, wh ich synthes i zes p recise steps
that coincide n,ith the exact center frequencies of all
assignable FCC ÂM andFM frequencies. The tuning system
is aáivated by either touch tuning button for up -T"lt- -
(highei numbers) or down scale (lower numbers)- The T14
provides two alternate methods of tuning with the touch
tuning system. The auto mode (out) provides tuning to
the nèxt available broadcast station.In the scan mode (in),
as long as either runing button is depressed, the runer will
continue to scan. Once released, it will stop at the next
FCC assigned frequency, whether there is a station there
or not. Once this digitally synthesized tuning system
reaches an assigned frequenÇy it will automatically activate
the Quartz-Lock. If a broadcast signal is present, the
Quartz-Lock will then precisely center to the station
fiequency for optimum performance. This digitally
synlhesized tuning method was first developed for
telemetry reception in NASA sPace Programs-
Frequency Readout - The blue fluorescent dig-ital
frequency readout is a precise Quartz reference frequency
couoter that displays either FM frequency in MHz
(millions of cycles) or AM frequency in KHz (1000's
of cycles).
Stereo - The stereo indicator becomes illuminated when
an FM Stereo (or multiplex) signal is being received by
the Tl4. In some instances, the signal level at the antenna
may be so low that the noise generated in stereo will be
unácceptable for listening Purposes- It is recommended
that thi mode switch be moved to the mono position
which will reduce the noise and defeat the stereo circuit'
However, this should only be done in the case of extremely
weak-stereo signals.
IF Band - The T14 provides selection of wide (out) or
narrow (in) Intermediate Frequency (IF) Filters' The
wide position is recommended for normal listening since
this provides optimum separation and low distortion'
The narrow position is recommended for weak signal
reception whlre a much stronger nearþ station
is interfering with it.
Memory - The T14 provides memory for 5 AM and 5 FM
stations. To store a státion in memory: l) select the desired
station; 2) press the memory button, then, 3) press the
desired memory location (I'2, )' 4, oç 5)'
DISPLRY
The dual fluorescent bar graph displays at the left hand
side of the T14, serve a multipurpose role'
AM/FM - lVhen the selector is moved to the AM/FM
poririott, the upper bar. graph- becomes the signal strength
ini¡.",oi for uãitr AM ãnðFM reception' The lower bar
i0

þraph display becomes the multipath distortion indicator
Ior FM tuning. As indicated in our discussion under FM
antenna, in tñe CONNECTIONS portion of this book,
multipath distortion can cause a very real and audible
distoriion problem in FM uning, this is not readily
indicated by signal strength or center runing. The
multipath dispiay can inãicate the presence of multipath
distortion, and is useful as an indicator in tuning your
antenna to reduce or remove this distortion. Optimum
reception is when signal strength indication is at its highest
levei and multipath distordon is at its lowest level.
Output - lVhen the display selector is -in the "Display
,{uó" or output position, the center scale is indicaæd in
dB and is refãrenceð to INVo modulation- This display
monitors the level appearing at the outPuts. This display
is more accurate andlesponsive than conventional meters,
and can be quite useful for monitoring channel balance,
broadcast signal strength and overall outPut.
Display Auto - !(/hen this button is depressed,'1"
follówing sequence occr¡rs: 1) when not runing the display
will indiãateã,ttp,rt level and the digital readout will
indicate time; 2) when either tune button is pushed, the
display automarically swirches to the Tuning Mode
Imultipath (FM), sþnal-strength (AM/FM)], and
itre digitat readout to frequency; 3) once tuning is -
compiãted (tune burton released) the display will change
back to srep 1, after 5 seconds.
If the Display t{.uto button is released, the display
will stay in rhC runing mode and the Frequency Readout
will indicate station frequencY.
Clock - The Tl4 incorporates a Quartz Reference Clock
which displays if the Clock button is pushed and the T14
is either: t) off with power supplied to the AC cord
or 2) the Display Auto switch is depressed and either
tune button is nor dePressed.
Clock Set - To set the clock, depress the Set and Hour
or Min buttons, depending on which needs to be reset'
If a power failure occurs oiwhen the T14 is first connected
the äisplay will flash to indicate that power has been lost.
Power Switch - The Power switch supplies Power to
the runer and the switched power outlets-
The lights come on when this switch is depressed.
If this doeJ not occur, Power is not being supplied
ro the tuner.
GENERRL MRNT€NRNCE
Great care has been taken to ensure that your runer
is as flawless in appearance as it is electronically. The panel
is finished with a high grade black anodize process for
durability as well as beauty. If it should become finger-
printed, it can best be cleaned by using a soft cloth
dampened with a solution of lþid detergent and water.
UNDER NO CIRCUMSTANCES SHOULD Á. LYE
SOLUTION OR ^AN ,ABRÁSIVE CLEANER SUCH ÂS
SCOURING POSTDER BE USED ON ANY PART OF
THE TUNER.
