@ Isohex Power Supply
ONKYO’'s exclusive |sohex Power Supply arranges the six main tuner circuits like the spokes of a wheel around a central power supply
hub. Independent supply and ground lines run from the power supply to each of the tuner circuits: to the display, to the quartz synthesizer,
to the front end, to the IF, to the FM PLL demodulator, and to the stereo MPX. By minimizing the distance between the power supply
and each circuit, this arrangement improves power supply control. By isolating the routes to the circuits, it also avoids interference.
® Outstanding Sensitivity and Tuning Precision a
One major reason for the T-407's excellent sensitivity and tuning precision is its RF section which uses five varactor diodes “ganged”
through the single tuning voltage source. This uncompromising design, coupled with MOS FETs and a dual local oscillator buffer, gives
the T-407 the sharp, precise reception listeners expect from an ONKYO tuner.
@ 40-Station FM/AM Random Preset Tuning
® Classified Memory Preset
On the T-407 the memory presets are organized into eight classes designated A-H. Each class can be assigned to a different type of
program material or a different member of the family. You can preview the stations in any particular class at the touch of a button.
® Direct Access Tuning
Instead of using the UP or DOWN tuning keys to scan through the available frequencies until the desired station is located, Direct Access
Tuning lets you punch in the broadcast frequency directly using the 10 numeric keys. For example, to select 103.5 MHz the user simply
presses the 1, 0, 3, 5 and O keys.

FM Antenna Connections
Depending on the strength and quality of FM signals in your area,
the accessory T-shaped antenna may give satisfactory reception
or you may need an external FM antenna. To use the T-shaped
antenna, spread the antenna on a wall, preferably outside or on the
ceiling, and try several positions to determine which gives the best
reception. If reception with the T-shaped antenna is unsatisfactory,
install a multi-element external FM antenna. Consult your ONKYO
Service Center about the right type for your area.
NOTES:
1. Do not use the same antenna for both FM and TV (or VCR)
reception since the FM and TV (or VCR) signals can interfere
with each other. If you must use a common FM/TV (or VCR)
antenna, use a directional linkage type splitter.
. Follow the directions below to connect an antenna adapter
to a 75 Ohm cable.
Do not connect both the indoor T-shaped antenna and an
outdoor FM antenna. If you decide to install an outdoor
antenna, be sure to disconnect the indoor T-shaped antenna.

AM Antenna Connections
An AM loop antenna is included in the installation instructions bag.
Take out the connection line and connect it to the AM antenna
terminals. This loop antenna can be used placed on top of the tuner
or attached to a wall or other surface. Try several positions to
determine which gives the best reception. Be sure the antenna is
not near a speaker, power cord, television set, VCR, or motorized
appliances. When using an external AM antenna, do not remove
the loop antenna; connect both antennas to the AM antenna ter-
minals.
FRI Remote Control jack ( I: Remote Interactive)
For remote control operation, connect this jack and any ONKYO
amplifier bearing the “ fRI ” mark using the remote control cable
included with this unit.(Station Up/Down buttons can be controlled
via remote control.) For more details, see the user’s manual for the
amplifier.
NOTE:
The fRI mark is ONKYO's own mark. Audio equipment with
this mark can be controlled through the amplifier with the
fRI mark, using remote control transmitter. Do not connect
any product to this jack that does not have the ONKYO RI
mark. Doing so can damage your equipment.
Memory Preservation
This unit does not require memory preservation batteries. A
built-in memory power back-up system preserves the contents
of the memory during power failures and even when the unit
is unplugged. The unit must be plugged in and the power switch
turned on and off once in order to charge the back-up system.
Note that since this is not a permanent memory, the power switch
must be turned on and off a few times each month to keep the
back-up system operative.
The memory preservation period after power has been turned
off varies depending on climate and placement of the unit. On
the average, memory contents are protected over a period of a
few weeks after the last time power has been turned off. This
period is shorter when the unit is exposed to a highly humid
climate.

-~ DOWN, UP
H@ Tuning with the tuning buttons
To tune in an FM or AM station not stored in the memory, press
the Tuning selector buttons. If you press UP, RF mode changes
to DX and the frequency is increased. Pressing DOWN decreases
the frequency. Note that the frequency is changed in 50kHz steps
in FM and 9/10kHz steps in AM when the Tuning selector
buttons is pressed in single steps. If this button is pressed
continuously for more than 0.5 second, auto tuning mode is
entered, and frequencies are scanned automatically. When a
broadcast signal is received, scanning stops. If a different fre-
quency is desired, press the button once again.
®@® Scanning will not stop for broadcasts weak enough to be
suppressed by the muting circuit. To receive a weak FM
broadcast, set the CABLE/MUTE button to the position the
CABLE indicator is on, and select the frequency of the desired
broadcast station in single steps.
Using the TUNING LEVEL button (FM only)
Each time this button is pressed, the auto tuning level is alter-
nately set to 20 dB or 35 dB. Use the 35 dB setting if there are
a lot of strong FM broadcasts in your area, and the 20 GB setting
if there are a lot of weak FM broadcasts in your area. The current
setting is shown in the multi function display for about two
seconds each time this selector is pressed. To receive broadcasts
below the level of 20 dB, set the CABLE/MUTE button to light
up CABLE indicator and tune. The displayed tuning level unit
of ‘dB’ is an abbreviation for dBf.

@ How to classify and memorize stations
The memory can be divided (classified) for different users or
programs of stations.
With this model, eight classes (CLASS A to H) are available
and stations can be memorized in any class. A total of 40 stations
can be memorized in classes from A to H. Although the same
station can be memorized in different classes, the memory
number for the station will differ depending on the order in which
the station is memorized in the classes.
@ Tune in the desired station (see previous section on the
tuning operations).
DX mode should be used when receiving a weak signal from a
far away station.
While LOCAL mode should be used when receiving a strong
signal from a nearby station.
When tuning, using either the tuning buttons or the number
from DX mode.
FM Stereo Indicator

@ To achieve more precise tuning of a cable broadcasting
station when receiving a cable FM (TV) broadcast
Use the UP or DOWN button to approximately locate the
broadcasting frequency in 50 kHz steps, then use the
CABLE/MUTE button to turn off FM muting and set the tuning
step to 25 kHz. The [CABLE indicator will light up so that manual
tuning of the broadcasting frequency can be performed using
the tuning selector button. During 25 kHz tuning step mode,
automatic tuning is disabled. The conditions picked up during
this Tuning Step Mode can be placed in memory.
NOTE:
When the CABLE mode is cancelled, the tuning frequency re-
turns to 50 kHz step mode.

@ ISOHEX Stromversorgungssystem
im neuen und exklusiven ISOHEX Stromversorgungssystem von ONKYO sind die einzeinen Schaltkreise des Tuners wie Speichen um
eine Radnabe um den zentralen Transformator herum angeordnet. Vollstandig unabhangige Stromversorgung und Masse fur jeden
einzelnen Schaltkreis, von der Leuchtanzeige, dem Quartz- Synthesizer, dem Eingangsschaltung, der IF-Zwischenfrequenz, dem UKW
PLL-Detektor bis hin zum Stereo MPX. Durch die Verkirzung der Stromversorgungsrouten wird eine entscheidende Verbesserung der
Stromzufuhrkontrolle gewahrleistet. Durch vdllige Abschirmung der Schaltkreise werden zudem jegliche Interferenzen vermieden.
@ Hervorragende Empfindlichkeitswerte und Tuninggenauigkeit
Den Hauptbeitrag zur hervorragenden Empfindlichkeit und Trennscharfe des T-407 liefert die Radio-Frequenz-Einheit, deren Bauprinzip
auf flinf Reaktanzdioden beruht, die durch eine einzelne Tuning- Spannungsquelle zu Gleichiauf verbundenen sind. Dieses kompromiRlose
Design, in Verbindung mit MOS FET’s und einem doppelten Empfangeroszillatorpuffer, schenken dem T-407 die Trennscharfe und
Empfangsprazision, die von einem ONKYO Tuner erwartet werden.
@ 40 UKW/MW-Senderspeicher, frei belegbar.
® Klassifizierte Senderspeicher
Die Senderspeicher des T-407 sind in acht Klassen aufgeteilt, was eine Ordnung und Verteilung der Senderspeicher nach Programm-
und Musikstil méglich macht, oder eine Aufteilung dieser Vorwahlen unter den Mitgliedern der Familie. Alle Sender einer Kiasse konnen
auf einfachem Tastendruck der Reihe nach kurz abgehort werden.
@ Direkt Access Tuning
Statt Sender wie gewohnt mit Frequenzbandreglern einzustellen, brauchen Sie nur die Frequenz des gewunschten Senders als Zahlenfolge
einzutippen, also zum Beispiel 1, 0, 3, 5 und 0, um den Sender auf UKW 103,5 einzustellen. Schneller kann es gar nicht gehen!
