Operating Voltage
Before connecting the unit to an AC outlet, be sure that the
operating voltage of your unit is identical with that of your local
power supply.
UK model ‘Operates on 240 V AC, 50 Hz.
AEP, Germany model Operates on 220 — 230 V AC,
50/60 Hz.
Operates on either 120 V, 220 V,
E model 240 V AC, adjustable, 50/60 Hz.
— 220V The voltage selector is located on
the rear panel. If you need to
wee 240 V change the selector, disconnect
the AC power cord and set the
—120V se.ector to the proper voltage of
your local power supply.

GENERAL
Front panel
POWER switch and indicator
After the power is turned on, the standby indicator lights
in red as the built-in muting circuit activates. When the
amplifier stays in a stable operating condition, the
indicator lights in green.
The indicator lights in red if the unit detects shorting of
circuit of the speaker outputs or in case of short-circuit
of the inputs of DC componenis. In such a case,
disconnect the power source and check the connected
components and speaker systems.
REC OUT SELECTOR
Selects the program source sent to the REC OUT jacks
for recording.
INPUT SELECTOR
Selects the desired program source for listening.
SOURCE DIRECT button and indicator
Depress the button. The red indicator lights and the
circuits of the TONE control, SUBSONIC filter button,
BALANCE contro! and MODE selector are disengaged
without regard to the setting of the switches.
MUTING button and indicator
Depress the button to reduce the sound level by 20 cB.
(Output voltage becomes 1/10.)
Generally, keep the button released (OFF).
[6] ATTENUATOR
Adjusts the sound level. To increase the sound level,
turn the control clockwise. To decrease the level, turn
the control counterclockwise.
Note
Turn down the sound level before switching on the unit.
This prevents damage to speakers.
CARTRIDGE LOAD selector
Set the selector according to your cartridge.
MM: For moving-magnet type cartridge
MC: For moving-coil type cartridge
40 Q: For a cartridge with an impedance of 40 ohms
or more.
3 Q: For a cartridge with an impedance of 3 ohms to
40 ohms.
DIRECT INPUT selector
Set to SOURCE to select program source with the
INPUT SELECTOR.
To listen to a program source processed through the
equipment, such as graphic equalizer, connected to the
ADAPTOR jacks, set it to ADAPTOR
To listen to a program source connected to DIRECT IN
jacks, set it to DIRECT.
[9] SUBSONIC filter button
Depress the button to reduce noise components of less
than 15 Hz, which cause modulation noise.
MODE selector
STEREO: For listening to a stereo program.
MONO: For listening to a monaural program.
BALANCE control
Adjusts the sound level of left and right speakers.
BASS and TREBLE TONE controls
Adjust the tone quality.
To increase bass or treble sound, turn the control
clockwise. To decrease them, turn the control
counterclockwise.
SPEAKERS buttons (TA-F222ESA/TA-F570ES/
TA-F670ES)
Select speaker system A or B, or both.
To drive speaker system A: Depress A button.
To drive speaker system B: Depress B button.
To drive speaker system A and B: Depress A and B.
For headphones listening only: Set both to OFF (1).
TA-F670ES only
To use power amplifier or active speaker system
connected to the PRE OUT jacks, depress B/PRE OUT.
SPEAKERS selector
Select speaker system A or B, or both.
To drive speaker system A: Set the selector to A.
To drive speaker system B: Set the selector to B.
To drive speaker system A and B: Set the selector A+B.
For headphones listening only: Set the selector to OFF.
To use power amplifier or active speaker system
connected to the PRE OUT jacks, set the selector to B/
PRE OUT.

Notes on Batteries .
Battery life
About half a year of normal operation can be expected
when using the Sony SUM-3 (NS) batteries. When the
batteries are exhausted, the remote commander can no
longer operate the unit. If this happens, replace both
batteries with new ones.
To avoid battery leakage
When the commander is not used for a long time, remove
the batteries to avoid damage caused by battery leakage
and corrosion.
To avoid mulfunction of the remote commander
Avoid keeping the commander under extremely hot or
humid locations. :

Notes
__
* Connect the AC power cord last of all. Make sure that the power is off when making connections.
* Cord plugs and jacks are color coded. Red plugs and jacks are for right channel (R) and white ones for the left
channel (L).
* Insert the cable connectors fully into the jacks. A loose connection may cause hum and noise.
¢ Connect the + and - cords of the speaker systems correctly to the + and — terminals of the amplifier respectively.
The numbers described @ correspond to the individual
connecting diagram.

To enjoy pure sound
Connect a CD player or a tuner to the DIRECT IN jacks. DIRECT IN circuitry bypasses the INPUT SELECTOR and REC
OUT SELECTOR so the signal is sent directly to the amplifier. Note that the program source input through DIRECT IN jacks
cannot be processed through an adaptor nor be output through REC OUT jacks.
