Safety Instructions

WARNINGS

CAUTIONS

Before starting
to use

In this owner’s manual and on the product, various pictures are used
to show our customers how to use Phasemation EA-1000 safely and
properly in order to avoid the loss of customer’s assets and to protect
our customers from harm.

Do not use the
equipment being
broken.

Never remodel the
equipment.

Never install the
equipment near
water.

Never put an object
filled with water on
the equipment.

Never put an object
inside the equipment.

Cautions of
Installation

Places which are not
suitable for
installation

Connection

In case of using the equipment in an abnormal
state, such as seeing smoke, having strange
smell and hearing unusual sounds or noise, this
can result in a risk of fire or electric shock. If
such an abnormal state occurs, turn the power
switch off, and endure to disconnect the AC plug
from the outlet. After no smoke is confirmed, ask
dealer for the repair.

Do not disassemble the equipment or do not
remodel it. This can result in a risk of fire.

Do not use the equipment in the bathroom. This
can result in a risk of fire or electric shock.

The equipment is designed for using indoors.
Do not expose the equipment to water. This can
result in a risk of failures, fire and electric shock.

Do not put a vase, flower pot, glass or any
object filled with skin lotion, chemical or water,
or small metal object on the equipment. In case
the liquids are spilled or the small objects fall
inside the equipment, this can result in a risk of
fire or electric shock.

If a foreign object has fallen inside the
equipment, turn the amplifier’s power switch off,
and contact the dealer. To keep using the
equipment can result in a risk of fire and electric
shock.

Do not install the equipment in the humid or
dusty environment. This can result in a risk of
fire or electric shock.

When connecting with other audio equipment or
a television set, read the manual of equipment,
turn the power switch off, and connect according
to the instructions.

Do not install the equipment on the unstable
tables or unstable places. In case the equipment
falls, it can result in a risk of injury of customers.

Pay attention to the wiring of the cord so that a
foot is not caught, or the person can stumble or
the equipment can fall, which is so dangerous.

When moving the equipment, turn the power
switch off, and endure to disconnect the power
plug from the outlet and remove the connecting
cord. The cord can be damaged and this can
result in a risk of fire and electric shock.

Usage Cautions

Care of Equipment

Note

In order to use the equipment for a long time, follow the instructions
shown in below:

Do not install this equipment near a heat source such as direct sun light, a stove and so on.
Do not use this equipment at a poorly-ventilated, humid or dusty place.
Do not install this equipment at an unstable place such as slope or vibrating place.
Do not install this equipment near the window where the equipment can be exposed to rain.
Do not install this equipment in high humidity environment.
Avoid using this equipment on equipment generating heat such as an amplifier.
Keep this equipment away from a power supply transformer or motor of other equipment.

AC 100V power supply must be supplied.
The equipment operates normally in the both areas of 50Hz and 60Hz power supply frequen

-

cies.

Do not touch the AC power cable with the wet hands.
Do not pull the cable strongly or do not bend the cable. The cable can be damaged and can
result in a risk of fire and electric shock.
Use the AC power cable of the accessories.

If the equipment is covered with dust or dirt, clean it with a soft cloth.

If the equipment is covered with heavy dust, put a very thin mild detergent on a soft cloth.
Wring the cloth and wipe off the dust and dirt. Then, clean with a dry soft cloth.

Never use chemical agents such as thinner, naphtha and alcohol when cleaning it.
If any of them is attached to the equipment, the silk printing can be flaked or the surface can
lose metal luster.

In the case of the equipment failure, consult the dealer.

Avoid covering the equipment with the cloth or installing it in enclosed space because
radiation and air convection from the chassis surface can be hindered.
To prevent external sound pressure, grit and dust from entering the equipment,
inspiratory/exhaust ports to radiate the heat are not arranged against the equipment
consciously. Radiating the heat from the equipment is realized by cooling with air convec

­tion in the chassis and with radiation and air convection from the chassis having high
thermal conductivity.

(15) GND terminal

Connect an earth cable from analogue disc player to one GND terminal of two GNDs of
L and R.

(16) DC IN connector

Connect the DC power junction cable of accessories between this DIN Connector and
the Power equipment.

Not to connect between L and R GNDs is recommended; however, define whether you
connect between them so as to match your audio system, or not.

Note

The XLR terminal is adopted as an unbalance terminal of OUTPUT for this product.
Pin assignment is as follows: pin-1: GND, pin-2: HOT and pin-3: GND.

Pin assignment of some power amplifier may be assigned as follows: pin-1: GND,
pin-2: COLD and pin-3: HOT. In this condition, the output signal is reproduced in the
opposite phase of the input signal.

To play it in the proper phase, exchange wirings of pin-2 and pin-3 at one end of
balance cable before connecting the XLR terminal.

Circle

A circle is assigned on the one side of the plug of
AC power cable so that better quality sound is
reproduced by matching the power supply polarity
with other equipment.

This polarity may be different because of house
wiring for outlet or because of power supply
condition; however, generally the side assigning
the circle should be inserted to the long slot of the
outlet.
