Amplifier connection 

 

 

 

The GZRA MICRO ONE comes with a power and signal connector cable. For a reliable connection we 

strongly recommend to use the delivered

 

spade connections or solder the joints. 

 

Make sure input connectors are making good contact with input jacks of the amplifier to avoid shortage or 

interruption 

 

Never use any other connector instead of the original Ground Zero connector. In case of a defective 

connector cable, please contact the Ground Zero service. 

 

Turning on the amplifier 

 
 

The amplifier automatically turns on a few seconds after you turn on your radio.  

Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools  

(At about 80° / 176° F). 

 
 

Adjusting the audio level 

 

1.

 

LEVEL (Min/Max): Turn fully counter- clockwise to MIN position 

2.

 

Turn the auto sound system's volume control to about two-third of its full range. 

3.

 

Adjust LEVEL to a comfortable listening level. 

 

WARNING !

 

High powered audio systems in a vehicle are capable of generating "Live Concert" levels of sound pressure. Continued 

exposure to excessively high volume sound levels may cause hearing loss or damage. Also, operation of a motor 

vehicle while listening to audio equipment at high volume levels may impair your ability to hear external sounds such 

as; horns, warning signals, or emergency vehicles, thus constituting to a potential traffic hazard. In the interest of safety, 

Consumer Electronics recommends listening at lower volume levels while driving.
