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 CA-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 or hearing unusual sounds or noises, 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
the dealer for the repair.
Do not disassemble the equipment or 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 substance
or water, or small metal objects 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 or 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 equipments
or a television set, read the manual of the
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 forth.
Do not use this equipment at a poorly-ventilated, humid or dusty place.
Do not install this equipment at an unstable place such as a 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 a high humid environment.
Avoid using this equipment on equipments generating heat such as an amplifier.
Keep this equipment away from a power supply transformer or a motor of an other equipment.
AC 230V power supply must be supplied.
The equipment operates normally in both areas of the 50Hz and 60Hz power supply frequen-
cies.
Do not touch the AC power cable with wet hands.
Do not pull the cable strongly or bend the cable. The cable can be damaged and can result in
a risk of fire or 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 or 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 case of the equipment failure, consult the dealer.
Avoid covering the equipment with cloth or installing it in an enclosed space because
radiation and air convection from the chassis surface can be hindered.
At the amplifier section, 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 it
with air convection in the chassis and with radiation and air convection from the chassis
having high thermal conductivity.

Names and Functions
Control & Power Section
Front Panel
This switch turns the power ON or OFF. After this switch is pressed to turn it to ON, a
blue indicator lights up and then, ‘30’ is displayed on (6) DISPLAY and it starts to count
down. While it is counting down, the product enters the ‘STANDBY’ mode and the other
functions and indicators are temporarily stopped. After the countdown finishes, the
control amplifier functions become available at the condition with each part being main-
tained before it was turned off.
(1) POWER switch/indicator
These respective switches select the desired input source to be played. The blue
indicator corresponding to the selected source lights up. The condition of the selected
input source is stored so even after the power is turned to OFF and ON, the same
source is selected.
(2) INPUT SELECTOR switches/indicators
This switch selects the desired amplifier gain as follows:
–6: Decreasing 6dB from the standard level
0: LEVEL 0dB (Standard level: 12dB)
+6: Increasing 6dB from the standard level
(4) LEVEL selection switch
This portion receives the light from the remote controller.
When installing the product, do not place an object disturbing the light between this portion and the remote
controller.
(5) Remote controller reception portion
This switch selects the desired output terminal as follows:
OFF: Not outputted
1: Unbalanced output through the RCA pin connector
2: Balanced output through the XLR connector
1+2: Both of them at the same time

This displays the attenuation (dB) of the attenuator; however, ‘– 99’ is close to nothing.
(6) Display portion
This knob controls the audio volume and the volume is increased by turning it right
(clockwise) and decreased by turning it left (counterclockwise).
(8) VOLUME knob
These indicate the setup due to the (10) BALANCE switches.
The center is blue and the other six are orange.
(9) BALANCE indicators
These switches adjust the volume difference between L-ch and R-ch. A maximum of a
three-step difference between L-ch and R-ch master-volume step can be set and the
setup is indicated by (9) BALANCE indicators.
* The difference is made by decreasing one of the master-volume steps of L-ch
and R-ch.
Example: When the center indicator (blue) lights up, when R-ch switch is
pressed once, the L-ch volume is decreased by one step.
* When the outside end indicator lights up, when that switch is pressed, the
indicator is changed from lighting-up to flashing and the other channel volume
level is changed to 0-step. (This operation is utilized for checking respective
channels.)
(10) BALANCE switches
This switch mutes the audio output and this indicator lights up. Then by pressing this
switch again, the muting mode is cancelled and the audio output is returned to the
previous level. The same operation can be controlled by using the MUTE switch of the
remote controller.
The ATT switch on the remote controller decreases the audio volume by 20dB from the
displayed level and this indicator flashes. Then by pressing the ATT switch again, the
attenuation mode is cancelled.
* The muting mode or the attenuation mode is cancelled by pressing the VOLUME UP,
VOLUME DOWN or BALANCE switch.

The balanced input circuit contains a transformer for this product. When the
balanced system to which a unbalanced system is converted by some
conversion adaptor is inputted to the balanced input of this product, the
original performance cannot be realized.
For the balanced input of this product, connect a balanced output.

For any equipment connected to this product through the RCA or XLR
connector, do not connect this GND terminal to it as earth; otherwise, an earth
loop formed between the equipment and this product deteriorates the sound
quality.
If necessary, utilize this GND terminal for a ground circuit separated against
an audio signal circuit, such as for a motor earth of an analog player, a
chassis of a MC step-up transformer, or earth.
This is the unbalanced output terminal to which the signal is directly outputted from the
built-in passive attenuator without passing through the amplifier section.
