SECTION 1
GENERAL
1-1. FUNCTION OF CONTROLS
Front panel
POWER switch and indicator
Turns the power on and off.
After the power is turned on, the standby
indicator lights red as the built-in muting
circuit activates. When the amplifier is
ready to operate, the indicator lights green.
If the unit detects shorting in the speaker
output circuits or in the DC component
inputs, the indicator lights red. In this case,
disconnect the power source and check the
connected components and speaker
systems.
Remote control sensor
INPUT SELECTOR
Selects the desired program source for
listening.
[4] MUTING button and indicator
Mutes the sound. Generally, keep the
button released (OFF).
SOURCE DIRECT button and
indicator
Deactivated the circuits of the TONE
control, SUBSONIC filter button, BALANCE
control and MODE selector without regard
to the setting of the switches. The indicator
lights red.
6} ATTENUATOR control
Adjusts the sound ijevel. To increase the
sound level, turn the control clockwise. To
decrease the level, turn the control
counterclockwise.
Caution
Turn down the sound level before switching
on the unit. This prevents damage to
speakers.
CARTRIDGE selector
Selects a position according to your
cartridge.
MM: For moving-magnet type cartridges
MC: For moving-coil type cartridges
This section is extracted from
instruction manual
(8) DIRECT INPUT selector
Selects the program source connected to
the DIRECT IN jacks or the other input
jacks.
DIRECT: For listening to a program source
connected to the DIRECT IN jacks.
SOURCE: For listening to a program
source connected to the other input jacks or
the ADAPTOR jacks, such as a graphic
equalizer.
(9] SUBSONIC filter button
Reduces the noise components of less than
15 Hz which cause modulation noise.
10] MODE selector
STEREO: For listening to a stereo program.
MONO: For listening to a monaural
program.
(11] BALANCE control
Adjusts the sound level of the left and right
speakers.
(1 BASS and TREBLE TONE controls
Adjusts the tone quality.
To increase bass or treble sound, turn the
control clockwise. To decrease them, turn
the control counterclockwise.
13] REC OUT SELECTOR
Selects the program source for the REC
OUT jacks.
SPEAKERS buttons
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-F690ES only
To use power amplifier or active speaker
system connected to the PRE OUT jacks,
depress B/PRE OUT.
HEADPHONES jack
Accepts headphones with the stereo phone
plug.

ELECTRICAL ADJUSTMENTS
Bias Adjustment
Note: Adjustment the idling after tuning the unit on for
about 10 minutes, giving it time to warm up.
Procedure :
1. Connect the digital voltmeter to VH4 on main board
sa follows.
2. Adjust RT301(L-CH) and RT351(R-CH) so that the
digital voltmeter on signal reads 24mV at VH4.
