high range output terminal.
To measure the acoustic characteristics of 

the vehicle cab, the auto time alignment and 

equalizer (Auto TA&EQ) emits a loud sound from 

the speakers. If the high range speaker (tweeter or 

super tweeter) is connected to a speaker terminal 

other than the high range output terminal, the 

speaker may be damaged by the measuring 

sound which includes low frequencies. Be sure 

to connect the high range speaker to the speaker 

output terminal for high signals.

super tweeter
•  Be sure to use the crossover network 

provided with the super tweeter.

•  The Auto TA&EQ may not be correctly 

adjusted. Adjust manually, if necessary.

•  This unit cannot be installed in a vehicle that 

does not have an ACC (accessory) position on the 

ignition switch.

No ACC position

•  Use this unit in other than the following 

conditions could result in fire or malfunction.

— Vehicles with a 12-volt battery and negative 

grounding.

•  To prevent short-circuit, overheating or 

malfunction, be sure to follow the directions 

below.

— Disconnect the negative terminal of the 

battery before installation.

— Secure the wiring with cable clamps or 

adhesive tape. To protect the wiring, wrap 

adhesive tape around them where they lie 

against metal parts.

— Place all cables away from moving parts, such 

as gear shift and seat rails.

— Place all cables away from hot places, such as 

near the heater outlet.

— Do not pass the yellow cable through a hole 

into the engine compartment to connect to a 

battery.

— Cover any disconnected cable connectors with 

insulating tape.

— Do not shorten any cables.

— Never cut the insulation of the power cable of 

this unit in order to share the power to other 

equipment. Current capacity of the cable is 

limited.

— Use a fuse of the rating prescribed.

— Never wire the speaker negative cable directly 

to ground.

•  Control signal is output through blue/white cable 

when this unit is powered on. Connect it to an 

external power amp’s system remote control or 

the vehicle’s auto-antenna relay control terminal 

(max. 300 mA, 12 V DC). If the vehicle is equipped 

with a glass antenna, connect it to the antenna 

booster power supply terminal.

•  Never connect blue/white cable to external power 

amp’s power terminal. Also, never connect 

it to the power terminal of the auto antenna. 

Otherwise, battery drain or malfunction may 

result.

•  IP-BUS connectors are color-coded. Be sure to 

connect connectors of the same color.

•  Black cable is ground. This cable and other 

product’s ground cable (especially, high-current 

products such as power amp) must be wired 

separately. Otherwise, fire or malfunction may 

result if they are accidentally detached.

•  Refer to the owner’s manual for details on 

connecting the power amp and other units, then 

make connections correctly.

•  If the RCA pin jack on the unit will not be used, 

do not remove the caps attached to the end of the 

connector.

•  When connecting tweeters, please confirm the 

tweeter’s usable frequency range. When you set 

the cut-off frequency, set higher than the lowest 

usable frequency of the tweeter.

•  Auto TA uses higher range than 10 kHz for 

measurement. Therefore, using the tweeter 

that cannot reproduce 10 kHz frequency range 

may damage the tweeter. When Auto TA&EQ is 

operated, be sure to set the appropriate cut-

off frequency. Also, use the tweeter that can 

reproduce 10 kHz at the lowest usable frequency.

Yellow/black (MUTE)

If you use an equipment with Mute function, wire this lead 
to the Audio Mute lead on that equipment. 
If not, keep the Audio Mute lead free of any connections.
