SETUP 

!

The ZH-1 is pre-configured at the factory with the most popular internal switch settings so nothing needs 

to be done to try out your new Zen Head.  Even a new high quality battery is pre-installed so all you have 

to do is plug in your source and a favorite set of headphones and enjoy. 

!

Just use the included 3.5mm stereo cable 

between your IPOD or portable device and the 

input jack on the ZH-1 labeled “SOURCE” 

!

Plug your headphones into the jack labeled 

“PHONES” 

!

Turn the VOLUME control all the way down 

(counter-clockwise) before you turn on the ZH-1.  

Once you see the green LED light come on, you 

can slowly raise the VOLUME control to the  

desired listening level. 

!

BATTERY 

!

A single 9 volt battery is used and easily accessible from the rear by a simple press of the thumb. You can 

use either Alkaline or Rechargeable batteries. If your using this with a hi-end source you may find 

Alkaline to sound better than rechargeable batteries.  If selecting between different types of Alkaline 

batteries, always go with the highest current rating.  Battery life is dependent on how loud you play the 

ZH-1 and the quality of the battery, but at a normal listening level you can expect around 50 hours. 

THE BATTERY SHOULD BE REPLACED IF

 the sound easily distorts when you raise the volume or if the 

green LED light is dim.
