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.

.
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.
