a lsohex Power Supply
ONKYO's exclusive lsohex Power Supply arranges the six ma¡n tuner circuits like the spokes of a wheel around a central power supply
hub. lndependentsupplyandgroundlinesrunfromthepowersupplytoeachofthetunercircuits:tothedisplay,tothequartzsynthesizer,
to the front end, to the lF, 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
One ma.jor reason for the T-407's excellent sensitivity and tuning precision is its RF section which uses five varactor diodes "ganged"
through the single tun¡ng voltage sorrc". ihis 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.
. O-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 stat¡ons in any particular class at the touch of a button.
o Direct Access Tuning
lnstead 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 0 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 exlernal FM antenna. To use the T-shaped
antenna, òpread rhe antenna on a wall, preferably outside or on the
ceiling, and try several positions to determine which gives the best
reception. lf reception with the T-shaped antenna is unsatisfactory,
install a mulli-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. lf you must use a common FMiTV (or VCR)
antenna, use a directional linkage type splitter.
2. Follow the direct¡ons below 10 connect an antenna adapter
to a 75 Ohm cable.
3. Do not connect both the indoor T-shaped antenna and an

Memory Preservation
This unit does not require memory prese¡vat¡on 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 un¡t is exposed to a highly humid
climate.

Operations
. Before tutning the power on, confirm that all connections have been made properly.
o All buttons on this.un¡t (except the power sw¡tch) are soft-touch buttons. When the power is turned on, all settings return to the same
ones set when power was last turned off. I RF mode, DX or LOCAL (FM only)
DX mode should be used when receiving a weak signal from a
FM, AM DIRECT TUNING farawaystation.
TUNING LEVEL - DOWN, UP-
While LOCAL mode should be used when receiving a strong
signal from a nearby stat¡on.
When tuning, using either the tuning buttons or the number
burtons, w¡th the APR button engaged, the RF mode will change
automat¡cally to DX mode.
lf LOCAL mode is required, press the RF mode button to switch
from DX mode.
I FM Stereo lndicator
This indicator lights when an FM broadcast is being received.
It does not light when a weak FM stereo broadcast ¡s being
received,
lf you want to listen to an FM broadcast in MONO mode, press
the MODE button to turn the Stereo lndicator off.
I 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
broadcastin.g. frequency in 50 kHz sleps, then use the
CABLE/MUTE button to turn off FM muting and set the tuning
step to 25 kHz. The IEABLEIindicator will light up so that manual
tuning of the broadcasting frequency can be performed using
the tun¡ng seleclor button. During 25 kH.z 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 tun¡ng frequency re-
turns to 50 kHz step mode.
Examples: 100.125 + 100.100 MHz
100.t75 + 100.150
100.100 + 100.100
I Tuning w¡th the tuning buttons
To tune in an FM or AM station not stored in the memory, press
the Tuning selector buttons. lf 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 9/1OkHz steps in AM when the Tuning selector
buttons is pressed in single steps. lf this button is pressed
continuously for more than 0.5 second, aulo tuning mode is
entered, and frequencies are scanned automatically. When a
broadcast signal is rèceived, scanning stops. lf a differenl fre-
quency is desired, press the button once again.
a Scann¡ng 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 stat¡on in single steps.
I 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 dB 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.

receive frequency range, the frequency flashes for two sec-
onds and then the previous frequency will be displayed.
. lf awrong frequencyhas been set, pressthe DIRECTTUNING
button and start aga¡n.
I How to classify and memorize stat¡ons
The memory can be divided (classified) for different users or
programs of stations.
W¡th this model, eight classes (CLASS A to H) are available
and stations can be memorized in any class. Atotal of 40stations
can be memorized in classes from A to H. Although the same
station can be memorized in different classes, the memory
number for the3tation 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).
@ Press the MEMORY button.
o The MEMORY ind¡cator will flash for 8 seconds.
@ Press the desired Classified Memory button (one of buttons
A to H).
a The stat¡on is memorized in the selected class with the
memory number which is the smallest of the unoccupièd
numbers in the class.
By repeating the operations above, up to 40 stations can be
memorized. lf an attempt is nrade to memorize 41 stations,
"FULL" will be displayed in the Frequency Display, indicating
that no more stât¡ons can be memorized.

I How to cancel memorized stat¡ons
Retrieve the class number you want to cancel (see "How to
retrieve.memorized stations") and then press the Dl RECT button
while holding down the MEMORY button. Another station can
be memorized with the memory number which has beén can-
celled.
I How to retrieve memorized stat¡ons
@ Press the Classified Memory button for the desired class.
o The memory number (station) which was last used in the
class will be received.
@ There are sovoral methods to proceed after the above opor-
ations are carried out. Use any of the following methods.
a. Pressing the same Classified Memory button again per-
mits the next preset memory number (station) lo be re-
ceived.
b. lnput the memoiy number you wish to receive by using
the Number buttons.
o lf the memory number consists of 2 digits, input two
numbers, immediately one after the other. For instance,
when inputting "15", "15" will not be registered if
you wa¡t more than one second before inputting "5",
resulting in only "1" being registered.
a lf a number other than a number from 1 to 40, or a
number which has not been memorized is input, the
number flashes for 2 seconds and then the number
which was displayed before will be displayed.
. lf a number between 1 and 4 is pressed, the display
and station are changed 1 second later.
c. Press the SCAN button
o Stat¡ons memorized in the present class will be
scanned in a order and the corresponding memory
number will flash in the Preset station display at each
scan. After the last memory number of the class is
reached, scanning starts again from the first memory
number of the class. Pressing the SCAN button again
stops scanning.
. Pressing the SCAN button after pressing the MEM-
ORY button, enables you to scan through the memory
numbers in all the classes one by one.
I APR (Automat¡c Precision Reception) System (FM only)
This unit is equipped with ONKYO's unique APR system that
automatically controls the Auto stereo/Mono reception modes,
lF bandwidth wide/narrow setting and FM auto hi-blend circuit
according to the quality (signal strength, distortion, etc.) of the
signal currently being received. Consequently, optimum re-
ception (the lowest distortion and highest S/N ratio) is assured
at all times. Note that the APR system functions only during
FM reception. An Auto Stereo/Mono Selector, lF bandwidth
selector and auto hi-blend selector are provided to allow man-
ually overriding these three APR controlled reception modes.
lf the station is retuned, or the APR button is pressed again
however, the or¡ginal APR selected modes will be restored.
The APR system functions automatically when using the UP
or DOWN .buttons, or direct tuning.
The APR settings are memorized when the station is memorized.
