interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit di erent from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
WARNING: Only peripherals complying with the FCC class B limits may be attached to this
equipment.
Changes or modi cations made to this equipment, not expressly approved by us or parties
authorized by us could void the user’s authority to operate the equipment. This device complies with
part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.

SAFETY INSTRUCTIONS
There are two categories of Safety Instructions included in this manual:
Product Warnings, (i.e., what must never be done to assure avoiding those hazards that
could cause bodily injury or property damage); and
User Directions (i.e., what must always be done to assure the safe use of your device).
The Safety Instructions contained in this manual have been categorized in accordance with the
seriousness of the potential hazards through the use of Signal Words. Those Signal Words, and their
intended meanings, are as follows:
DANGER: Indicates that a failure to observe the Safety Instructions could result in death or
catastrophic bodily injury.
WARNING: Indicates that a failure to observe the Safety Instructions could result in serious bodily
injury.
CAUTION: Indicates that a failure to observe the Safety Instructions could result in minor bodily
injury or property damage.
NOTE: Designates important information that relates to activities and/or conditions that might
result in loss of data and/or damage to your device.
Safe Use and Operation of Your Device
This equipment emits stray RF energy and will interfere with the reception of signals by airborne
electronic navigational devices or medical devices. Do not operate this equipment near any sensitive
medical devices.
WARNING: Use only grounded AC power cords.
Always immediately disconnect the power to the equipment in the event the device emits an unusual
odor or sound or generates smoke.
04
WARNING: Never attempt to disassemble, repair or make any modi cation to your device.
Disassembly, modi cation or any attempt at repair could cause bodily injury or property damage, as
well as damage to the device itself.
WARNING: Your device is not a toy. Never allow children to play with your device. Misuse, rough or
improper handling of your device by children could result in serious bodily injury for any of the
enumerated safety warnings in this manual. In addition, always keep all accessories and components
out of the reach of small children as small parts might present a choking hazard. Seek immediate
medical attention if choking occurs or if any small part has been swallowed.
CAUTION: Never raise the sound volume level too high when using your device with earphones. An
excessive sound volume level could cause damage to your hearing.
WARNING: To reduce the risk of re or electric shock, do not expose the unit to moisture or water.
Do not allow foreign objects to get into the enclosure. If the unit is exposed to moisture, or a foreign
object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit
to a quali ed service person for inspection and necessary repairs.
Read all the instructions before connecting or operating the component.
Keep this manual so you can refer to these safety instructions.
Heed all warnings and safety information in these instructions and on the product itself. Follow all
operating instructions.
Do not use this unit near water.
You must allow a minimum 10 cm or 4 inches of unobstructed clearance around the unit. Do not
place the unit on a bed, sofa, rug, or similar surface that could block the ventilation openings. If the
unit is placed in a bookcase or cabinet, there must be ventilation of the cabinet to allow proper
cooling. Keep the component away from radiators, heat registers, stoves, or any other appliance that
produces heat.
05
The unit must be connected to a power supply only of the type and voltage speci ed on the rear
panel. Connect the component to the power outlet only with the supplied power supply cable or an
exact equivalent. Do not modify the supplied cable.
Do not route the power cord where it will be crushed, pinched, bent, exposed to heat, or damaged in
any way. Pay particular attention to the power cord at the plug and where the cord exits the back of
the unit.
The power cord should be unplugged from the wall outlet during a lightning storm or if the unit is to
be left unused for a long period of time.
Immediately stop using the component and have it inspected and/or serviced by a quali ed service
agency if:
The power supply cord or plug has been damaged.
Objects have fallen or liquid has been spilled into the unit.
The unit has been exposed to rain.
The unit shows signs of improper operation.
The unit has been dropped or damaged in any way

Background
NuPrime is not a Switching Digital Ampli er
Switching Digital Amps, commonly known as Class-D, rst appeared some decades ago. From the
start, Class-D showed enormous potential along with signi cant shortcomings: limited usable
bandwidth, and a xed saw-tooth waveform for audio- signal modulation, the latter producing jitter
that e ectively masks low-level signals.
Instead of the conventional saw-tooth con guration, NuPrime’s patented circuit design uses a
naturally occurring analog-modulating signal that adds neither noise nor jitter. Rather than reverting
to o -the-shelf solutions, NuPrime’s in-house advances have further unlocked the switching amp’s
potential without the di culties pure digital-switching ampli ers simply cannot avoid – in other
words, the best of both worlds.
Once upon a time heat and bulk were badges of status. Today, they’re the bane of obsolescent
technology. NuPrime amps switch at 500,000Hz – more than 10X the CD sampling rate. At these
frequencies, transformers and capacitors work far more e ciently, making it possible to reduce their
size. Typically, Class-A amps rarely utilize more than 30% of the power they draw; the rest is wasted
as heat. High operating temperatures also shorten the useful life of the electrolytic capacitors used in
abundance in these designs.
A comparison with traditional designs is mind-boggling. A NuPrime amp, small enough to sit on the
palm of one’s hand, is, typically, 85% e cient – in practical terms, cool-running and easy on the
utility bill.
