T R A N S PA R E N C Y M O D E TURNING TRANSPARENCY MODE ON One of the unique features of the EAR3H is the Transparent Mic. With the flick of a switch on the side of the unit, the ambient sounds from your surroundings are mixed in with the audio source, enabling you to be aware of what’s around you as you enjoy your amplified audio.
PAGE 13
5 6 Adjust the overall volume with the volume knob of the EAR3H Amp. This will adjust both the music and the ambient sounds volume at the same time. Fine tune the desired volume between music and ambient sounds by using the audio source volume control. Tip: For the audio source to be louder than the ambient sounds, turn up the volume on the audio source and reduce the EAR3H volume.
PAGE 14
TURNING TRANSPARENCY MODE OFF When using the EAR3H in environments where ambient sounds do not need to be heard, disable the Transparent Mic for the EAR3H to only amplify the audio source. The sound will be cleaner and more solid than using a direct signal from your audio source, and is capable of putting out higher volume compared to connecting to the audio source directly. TRANSARENCY MODE OFF WARNING: Use caution when turning the volume up to higher levels on the EAR3H.
