Safety Precautions
Caution: To prevent possible hearing damage,
avoid listening at high volume levels for long periods.
RemoteAmp contains a headphone amplier 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 RemoteAmp was designed to be very rugged and durable,
it is not waterproof and care should be taken to keep the unit dry.

5. 1/8"Stereo Line Input
Connect the headphone output of
any device to this low impedance
unbalanced stereo 1/8" (3.5mm)
Line Input jack.

The input XLR accepts line level
signals from your mixer, distribution
amplier or phone line hybrid.
The balanced input XLR is wired:
Pin 1 Pin 2 Pin 3
Ground Signal + Signal -
This is a transformer balanced input.
If you are using an unbalanced
source, you must connect your signal
lead to Pin 2 and then connect your
ground to Pins 1 and 3.

both the mono XLR and stereo
1/8" (3.5mm) inputs.

Gain Adjustment
Behind the back cover of the
RemoteAmp you will nd two jumpers
on the circuit board — J7 for the
Left channel and J8 for the Right
channel. These jumpers allow you
to adjust the maximum amount of
gain the RemoteAmp delivers. In
the factory default open position you
will receive a maximum of 25 dB
gain. If the jumpers are set to the
optional closed position, a maximum
of 40 dB gain will be delivered.
Operation
Battery
An alkaline battery is strongly
recommended. The battery test
indicator shows the strength of the
battery power remaining. A bright
light indicates plenty of power,
a dim light reminds you to be
prepared with a fresh battery. Once
the LED stops responding to the
test switch, you will begin to hear
signal breakup and distortion as the
battery is drained of its last breath
which may mean minutes or hours
depending on the circumstances.

FAQs 5
Will the RemoteAmp work
with my QuickTap IFB?
Yes. The RemoteAmp will take the
balanced output from the QuickTap
IFB and send it to a 1/4" Stereo
Headphone Jack as well as a 1/8"
(3.5mm) Stereo Headphone Jack.
You can now use headphones, an
earpiece or both.
Can I get more gain out of my
RemoteAmp?
Yes. Take the back o󰀨 of the
RemoteAmp and install both jumpers
(J7,J8). This will give you enough gain
to boost a healthy microphone level
signal to headphone level output.
