Power Meters (peak reading type)
12
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 figures
must be doubled, and with a 16-ohm load halved. Output levels with a sine-
wave signal for various loads are shown below.
Output indication
4-ohm load
(dB/%)
0 dB: 100 % 180 W
–10 dB: 10 % 18 W
–20 dB: 1 % 1.8 W
–30 dB: 0.1 % 180 mW
–40 dB: 0.01 % 18 mW
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
13
The infrared signals from the supplied remote commander RC-23 are
received by this sensor. When using the remote commander, point
the transmitter in the direction of this sensor.
VOLUME – Volume Control
14
Turning this control clockwise increases the volume level. The control
can also be operated with the remote commander RC-23.
Caution: When changing the setting of the EXT PRE selector ON/OFF,
when changing program sources, and when turning the power on and
off, the volume control should always be fully turned down.
INPUTS: TUNER, CD, LINE – Line-level Inputs
15
These inputs are conventional unbalanced line-level input jacks.
LINE INPUTS (BALANCED) – Balanced Inputs
16
These inputs are conventional balanced high-level input jacks.
The pin assignment of the connectors is as follows.
Make sure that the source component uses the same pin assignment.
A: Ground
B: Inverted (–)
C: Non-inverted (+)
Balanced cables are available from Accuphase.
RECORDER – Recorder REC/PLAY Jacks
17
These jacks serve for connection of a recorder.
"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
compensator settings of the amplifier.
✽ Keep in mind that when the MONO button is engaged, the recording output
will be monophonic.
POWER IN – Power Amplifier Input Jacks
18
POWER IN (EXT PRE IN)
These jacks permit using the power amplifier section separately.
m When the EXT PRE selector has been set to "ON" for separating the
preamplifier and power amplifier of the E-213, these jacks serve as power
amplifier input jacks. Input source switching, volume adjustment, and other
preamplifier functions must be performed at the external equipment.
Caution: Before connecting the cable, be sure to turn power OFF.

SPEAKERS A, B – Speaker Terminals
19
Two pairs of speakers can be connected to the A and B terminals.
✽ Use speakers with a rated impedance of 4 to 16 ohms.
✽ When driving both sets 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
20
Insert the supplied power cord into this connector and plug the other
end into an AC outlet.
RWARNING
m Do not use the unit with any other than the supplied power cord.
m The shape of the AC inlet and the plug of the supplied power cord depend
on the destination country of the unit. Using any other type of cable
except the supplied power cord poses the risk of fire and damage.
m This product is available in versions for 120/230 V AC. Make sure that
the voltage shown on the rear panel matches the AC line voltage in your
area.
m Opening the unit involves a severe risk of electric shock.
m If the unit does not operate, the internal fuse may have blown. Never
attempt to replace the fuse yourself. Be sure to contact your Accuphase
dealer or an authorized service station.
