Option Boards
The rear panel of the E-407 provides two slots in which an optional input board can be installed easily.
Two types of boards, as shown below, are available.
m Analog Disc Input Board AD-9 and Line Input Board LINE-9 can also be used.
m Both boards use the AAB (Accuphase Analog Bus) interface.
Line Inputs Board LINE-10
This option board provides an additional set of
conventional line inputs which can be used to
connect a CD player, tuner, or other component
with analog output.
Analog Disc Input Board AD-10
This board contains a high-performance, high
gain phone equalizer. The board can be used
with any type of phone cartridge.
Internal DIP switches control MM/MC operation, MC input
impedance, and subsonic filter on/off.
Gain : 36 dB
Input impedance : 47 kohms
Gain : 62 dB
Input impedance : 10/30/100 ohms

Remarks
H
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.
H
The 230 V AC model does not have the SWITCHED power outlet.
H
The shape of the AC inlet, plug of the supplied power cord, and AC outlet depends on the voltage rating and destination country.
H
These switched AC outlets may not be supplied depending on the safety standards or regulations applicable in the particular country to where the unit is destined.
Supplied accessories: • AC power cord
• Remote commander RC-20

Versatile input configuration including bal-
anced connectors
The input selector of the E-407 controls a total of
eight positions (including two option board posi-
tions) plus
two tape re-
corders. Two
of the stand-
ard inputs
(CD and
LINE) are de-
signed for
balanced connections which are not affected by
externally induced noise, ensuring signal trans-
mission with optimum sonic purity.
High-quality volume control, supplied remote
commander allows source switching and vol-
ume adjustment
Separator switch and set of inputs/outputs en-
able independent use of preamplifier and
power amplifier sections
