AuxAmp2 is a stereo headset amplifier designed to
allow a user to connect his conventional 5 pin DIN headset to a
multifunction GPS or cellphone (e.g. zumo, nuvi, iPhone, Blackberry).
connects to these devices via KTG’s Alert Harnesses, Stereo Harnesses, GPS Harnesses, or KTG audio switchers (e.g. AuxSwitchSet).
AuxAmp2 comes suppled with a power harness (and
a variety of power splices and lugs), and a 6 ft. long, weather booted,
5 pin DIN female headset harness.
AuxAmp2 contains a power filter
that will supply up to 3 Amps of filtered current from the vehicle’s
power source to the user’s audio device. The
3 Amp output is internally fused via a solid state device.
AuxAmp2 has two gain ranges, selectable by the rider. A high gain
range is available for conventional headset headphones; a low gain
range is for earbud users.
has an alert device input (compatible with all Kennedy alert device
harnesses) that can be set to mute the stereo or GPS source
Cost: $95.00 + shipping.
AN IMPORTANT NOTE ABOUT WIND NOISE
AuxAmp2 was designed to connect to dynamic (passive) microphone
elements. While these elements exhibit excellent noise rejection,
they are still susceptible to the effects of wind noise and vibration.
noise can be minimized by encasing the microphone element in a stiff,
plastic enclosure and by allowing audio to access the element via two
or three small (1/32” diameter or less) holes placed directly over the
element’s membrane. These small holes require the microphone be
positioned close to, and directly in front of, the user’s mouth.
face helmets: The microphone element should be as physically insulated
from the helmet as possible. This will lessen the amount of wind
vibration transmitted from the helmet to the microphone element. The
use of foam padding and rubber will be required.
Three quarter and half helmets: The microphone is not as susceptible to helmet vibration, due to the boom element
