Safety Precautions
Caution, Avoid Listening at High Volume Levels
for Long Periods
Outerloop 3.5 contains a headphone amplier that is more powerful
than the typical consumer product.
JK Audio products are designed for the broadcast industry. The
broadcast professional must be able to hear headphone signals over
the ambient noise level. From the cheering crowd at a football game
to trackside at a car race, the program material or cues must be heard
at high volumes without distortion.
Road Safety
Never use headphones while driving or cycling, etc. It can be
dangerous to turn up the volume even while walking. Doing so may
hinder your hearing and can be hazardous on the roadways or at
pedestrian crossings.
Handle with Care
While Outerloop 3.5 was designed to be very rugged and durable,
it is not waterproof and care should be taken to keep the unit dry.

Features
HD Voice
While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD Voice calls
oer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives voice a
more natural sound, while the additional upper octave dramatically improves speech clarity
and intelligibility.
Wireless HD Calls
To take advantage of this extended bandwidth, both phones on the call must support HD
Voice, and both phones must be on the same carrier, in coverage areas that support HD
Voice.
