INSTALLATION
The car amplifier can be mounted in the dashboard or center console of
the car. (The mounting method differs depending on the type of the
car.) It can also be mounted under the dashboard using the supplied
mounting kit.
When using the supplied mounting kit, attach the mounting bracket to
the dashboard first, and then the amplifier to the bracket.
Note: To avoid the amplifier's failure, do not use devices other than the
supplied mounting kit when installing.
CONNECTIONS
Connect the power supply and speaker as follows:
Notes
The amplifier cannot be installed in the car using a 24 V battery.
The amplifier cannot be installed in the car of the positive grounding
type.
See to it that the amplifier's output does not exceed the speaker's
(total) permissible input.
Ensure that the amplifier's output impedance matches the speaker's
total impedance. The amplifier may fail if they are not matched.

Connect the red cord directly to the positive + terminal of the
battery, and the blue cord to the negative - terminal.
Insulate joints between the power cord and battery terminal with
the vinyl tape.
Thank you very much for purchasing TOA's
Car Amplifier. To prolong the life of your
amplifier by operating and using it correctly,
please read this instruction manual
carefully. The Car Amplifier with a rated
output of 15 W (CA-115), 30 W (CA-130),
and 60 W (CA-160) is suited to general
public address applications made from cars.
SAFETY PRECAUTIONS
Be sure to read the instructions in this section carefully before use.
Make sure to observe the instructions in this manual as the conventions of safety
symbols and messages regarded as very important precautions are included.
We also recommend you keep this instruction manual handy for future reference.
Indicates a potentially hazardous situation which, if
mishandled, could result in death or serious
personal injury.

OPERATION
1. Press the power switch and ensure that the power indicator
lights. (If the power indicator does not light, check the power cord
for correct connection.)
2. Insert the microphone plug into Mic 1 input jack .
3. Turn on the microphone switch and adjust the volume using Mic 1
volume control . When using Mic 2, connect the microphone to Mic
2 input jack and adjust the volume with Mic 2 volume control .
Up to two microphones can be used per amplifier.
4. When using a tape recorder or radio, connect the earphone terminal
or LINE OUT terminal of the tape recorder, etc. to the auxiliary input
jack by means of a shielded wire. Use the volume control of the
tape recorder, etc. to adjust the volume.
To connect the amplifier to the tape recorder, use either a
commercial "phone plug-to-miniature plug" cord or such a
connection cord as is shown below.
Solder Hot and Cold in the shielded cable correctly so that they
do not contact each other.
Note: The design and specifications are subject to change without notice for improvement.
