✔ Re-usable hospital grade sensors included!
✔ Monitor output for professional scope display
✔ Simple and safe 9V battery operation
February is the month for
Valentine’s Day, and what a great time
to think of your heart! Not how many times
it’s been broken, not how many times it’s fallen head over heels in love, but how it actually
works... and how it’s doing these days!
Use the ECG1C to astound your physician with your knowledge of ECG/EKG systems.
Enjoy learning about the inner workings of the heart while, at the same time, covering the stage-by-stage electronic circuit theory used in the kit to monitor it. The three
probe wire pick-ups allow for easy application and experimentation without the cumbersome harness normally associated with ECG monitors. The documentation with ECG1C covers everything from the circuit description of the kit to the circuit description of the heart! Multiple “beat” indicators include a bright front panel LED
that flashes with the actions of the heart along with an adjustable level audio speaker output that supports
both mono and stereo hook-ups. In addition a monitor output is provided to connect to any standard oscilloscope to view the traditional style ECG/EKG waveforms just like you see on ER... or in the ER! See the display
above? That’s one of our engineers, hooked up to the ECG1C after an engineering meeting!
The fully adjustable gain control on the front panel allows the user to custom tune the differential signal
picked up by the probes giving you a perfect reading and display every time! 10 hospital grade re-usable
probe patches are included together with the matching custom case set shown. Additional patches are available in 10-packs. Operates on a standard 9VDC battery (not included) for safe and simple operation. Note,
while the ECG1C professionally monitors and displays your heart rhythms and functions, it is intended for hobbyist usage only. If you experience any cardiac symptoms, seek proper medical help immediately!

✔ 2 independent 20W
amplifiers in one
✔ Super efficient
Class D spread
✔ Built-in click and
✔ Selectable gain
from +22dB to +36dB!
✔ Logic level mute and shutdown!
✔ Runs cool, no heat sink required!
✔ Built-in thermal protection!
✔ Runs on 10 to 18 VDC
The UAM4 is the big brother to the extremely popular UAM2. It uses the latest spread spectrum
amplifier technology to bring you clear, crisp, high-power audio without any of the heat which is normally associated with such an amplifier. Its
extremely clean Class D design produces two
independent 20 watt outputs! This can also be
bridged to an extremely efficient (87%!) single
channel (mono) 40 watt amplifier.
And at 40 watts, you’re probably already wondering about the heatsink requirements to dissipate
the heat, right? Stop wondering, there’s no heat,
so there is no heatsink required! And all that
power is generated in a single SMT device the size
of your thumbnail on a small 2½” square board!
The high impedance input is designed to use your
choice of either a balanced line input or an unbalanced signal source using easy to connect Euro
terminal blocks. Logic connections to ground are
also provided to mute and/or shut down the
amplifier. You can also enable the built-in over
temperature signal to activate one of these controls automatically! Easy to use board jumpers
offer selectable gain of +22dB, +25dB, + 29.5dB or
+36dB to match your input levels. Board jumpers
also enable protection and shutdown options as
well as stereo/mono/bridge mode. The amplifier
also features built-in click and pop suppression to
protect not only your ears and sanity, but your
speakers and equipment!
Power input for maximum rated output is 18VDC
at 2.64A. Input voltage can be reduced to a minimum of 10VDC while maintaining the same high
efficiency operation with reduced output power. If
you’re looking for an incredible stand-alone stereo
(or mono) amplifier to build into your equipment,
vehicle, speakers, or application, the UAM4 is the
latest and the greatest!
