Option Boards; Connection Cables - Accuphase E-213 Instruction Manual

OPTION BOARDS

Three types of option boards can be used in the E-213: the Digital Input Board DAC-10, the Analog Disc Input Board AD-9, and the Line Input Board LINE-9. These
boards can be installed in the rear-panel slot as required.
m m m m m The Analog Disc Input Board AD-10 and the Line Input Board LINE-10 can also be used.
USING AN OPTION BOARD
Playback of CDs or similar with digital input
Install the Digital Input Board DAC-10.
Caution: Be sure to turn power to the E-213 off before installing or
removing an option board.
✽ The board can handle digital output signals from a CD player, DAT recorder,
MD recorder or another digital component with a sampling frequency of up
to 96 kHz.
The connection can be made with coaxial or optical fiber cable.
Digital Input Board DAC-10
This board can be used for optical and/or coaxial input of
digital music signals from source components with digital
output.

Connection cables

COAXIAL: For 75-ohm coaxial cable
OPTICAL: For Toslink optical fiber cable
(OPTICAL input has automatic priority.)
Guaranteed specifications, standards
Input format: EIAJ CP-1201/AES-3 compliant
Sampling frequency: 32 – 96 kHz
Digital input: COAXIAL 0.5 Vp-p, 75 ohms
OPTICAL –27 to –15 dBm
Connection cables
COAXIAL: Use a 75-ohm coaxial cable with RCA plugs.
OPTICAL: This is a connector for EIAJ standard Toslink optical fiber cable.

Playback
a Verify that the VOLUME control is turned fully down and then turn on the
E-213 and the other components. Select the OPTION position of the input
selector. (This position is for the slot where the DAC-10 is installed.)
b Set the source component to the play condition and adjust the volume to a
suitable level.
Note
When both the COAXIAL and the OPTICAL inputs are connected, the OPTICAL
connector is automatically given priority.
m When signals are present at both connectors, the source connected to the
OPTICAL (Toslink optical fiber) input will be heard.
m To play back the signal from the component connected to the COAXIAL
connector, disconnect the OPTICAL input or turn power to the component
connected to the OPTICAL input off.
m If a signal appears at the OPTICAL input during playback of the signal from
the COAXIAL input, playback will switch to the OPTICAL input.

Analog Disc (AD) Input
Install the Analog Disc Input Board AD-9 (or AD-10).
Caution: Be sure to turn power to the E-213 off before installing or
Before inserting the board, the following settings must be made using
the DIP switches on the board.

As a general guideline, set this switch according
to the rated internal impedance of the MC cartridge.
20 ohms or more:
Less than 20 ohms: 30 Ω or 10 Ω position
m Generally, the input impedance setting should
be about 2 to 3 times the rated cartridge
impedance. However, since the requirements
of some cartridges may vary, the final setting
should be determined by ear.
m The S3 switch affects both the left and right
channels.
This filter has a cut-off frequency of 25 Hz and a
steep attenuation slope of –12 dB/octave. It cuts
off unwanted subsonic signal components without
affecting the audible range. Removing subsonic
noise components is useful for example to stop
excessive woofer excursions caused by record
warps, turntable rumble, etc.
