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-

Balanced input connectors

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

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

m Specifications and design subject to change without notice for improvements.

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

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

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.
