PHONES – Headphone jack
Stereo headphones can be plugged into this jack.
✽ When wishing to listen with headphones only, set the SPEAKERS selector to
OFF.
✽ Adjust the listening level with the main volume control.
✽ Use headphones with an impedance between 8 and 100 ohms.
Note:
When the preamplifi er and power amplifi er sections have been separated
by setting the EXT PRE button to ON, this headphone jack carries the same
signal as the power amplifi er section of the E-350. The volume therefore must
be adjusted at the external preamplifi er.

INPUT SELECTOR – Input selector
Serves to select the various program sources connected to the rear
panel inputs. The corresponding buttons on the remote commander
RC-200 can also be used.
TUNER, CD, LINE 1, 2
Selects components connected to the conventional unbalanced inputs (for
unbalanced audio cable with plugs) on the rear panel.
CD-BAL, LINE-BAL
Selects components connected to the balanced inputs (for balanced audio
cable) on the rear panel.
OPTION 1, 2
Select components connected to option boards installed in the OPTION 1 and
OPTION 2 slots on the rear panel.
● For information on option boards, see “Option boards”.
✽ The INPUT SELECTOR has no marking or end stopper (it can be turned
continuously).

Peak power meters
The meter scale indicates the output level in dB (decibel) and is also
calibrated in watts for an 8-ohm load. With a 4-ohm load, the fi gures
must be doubled, and with a 16-ohm load halved. Output levels with a
sine-wave signal for various loads are shown below.
The meters are peak-reading designs, which enables them to precisely follow the
rapid changes in amplitude and frequency that are common with music signals. To
make for easier reading, the decay time of the meters is set to a lower value than
the rise time. If the program source contains noise or a large amount of transients,
the meter indication and the aural volume impression may differ slightly.
Remote sensor
The infrared signals from the supplied remote commander RC-200 are
received by this sensor. When using the remote commander, point the
transmitter in the direction of this sensor.
Output indication
(dB/%)
4-ohm load 8-ohm load 16-ohm load
0 dB: 100 % 200 W 100 W 50 W
–10 dB: 10 % 20 W 10 W 5 W
–20 dB: 1 % 2 W 1 W 500 mW
–30 dB: 0.1 % 200 mW 100 mW 50 mW
–40 dB: 0.01 % 20 mW 10 mW 5 mW

CD/LINE INPUTS (BALANCED) – Balanced inputs
These are inputs for a balanced connection which eliminates externally
induced noise. The inputs accept the signal of any component with
balanced outputs, such as a CD player or tuner.
A: Ground
B: Inverted (–)
C: Non-inverted (+)
● Balanced audio cables are available from Accuphase.

INPUTS: TUNER, CD, LINE 1, LINE 2 – Line-level inputs
These inputs are conventional unbalanced line input jacks.
RECORDER 1, 2 – Recorder input/output jacks
These jacks serve for connection of two recorders.
PLAY jacks LINE OUT jacks of recorder
REC jacks LINE IN jacks of recorder
✽ The output signal at the REC jacks is not affected by the volume and tone
controls, or compensator settings of the amplifi er.
✽ Keep in mind that when the MODE switch is set to “MONO”, the recording
output will be monophonic.
22
PRE OUT/POWER IN (EXT PRE IN) jacks
PRE OUT
These jacks permit using the preamplifi er section separately.
● The signal at these jacks is always output, regardless of the setting of the
EXT PRE button.
● The outputs can be used to connect a second power amplifi er for bi-
amping.
✽
Bi-amping refers to using separate power amplifi ers for the low frequency range
and mid/high frequency range.
POWER IN (EXT PRE IN)
These jacks permit using the power amplifi er section separately.
● When the EXT PRE button has been set to “ON” for separating the
preamplifi er and power amplifi er of the E-350, these jacks serve as power
amplifi er input jacks. Input source switching, volume adjustment, and other
preamplifi er functions must be performed at the external equipment.
23
SPEAKERS terminals (A, B)
Two pairs of speakers can be connected to the terminals A and B.
✽ Use speakers with a rated impedance of 4 to 16 ohms.
✽ When driving two pairs of speakers simultaneously, use speakers with a rated
impedance of 8 to 16 ohms.
✽ For a biwiring arrangement, connect the cables for the low frequency range
and mid/high frequency range separately to terminals A and B.
AC Inlet
Insert the supplied power cord into this connector and plug the other
end into an AC outlet.
24
What is AAVA-II?
The E-350 incorporates an innovative volume control called AAVA-II
(Accuphase Analog Vari-gain Amplifi er-II). The operation principle of this
control is totally different from conventional controls using resistors. With
AAVA-II, the music signal is weighted in 16 stages, and a current switching
circuit serves to select the signal, thereby changing the volume.
In actual operation, a conventional rotary VR is used. When the
18
VOLUME
knob is turned, its position is detected by the adjustment circuit, and 16 current
switches are set to ON or OFF accordingly.
Note:
When high-effi ciency loudspeakers are used, a sound caused by the current
switch operation may be heard when turning the VOLUME knob. This is not
a defect.

VOLUME – Volume control
Turning this control clockwise increases the listening level. The control
can also be operated with the remote commander RC-200.
Note:
When changing the setting of the EXT PRE button, when changing program
sources, and when switching the power on and off, the volume control should
always be turned fully down.
