CAUTION
The amplifier should be plugged to power socket with ground connection. Please note that
tubes can reach operational temperature with exceeding 150 Celsius(300 F) therefore tube
exchange should be done with the device unplugged from AC power, after allowing the tubes
toer supply from the mains. Remove the damaged tube after cooldown of the device (min. 15
minutes).
WARRANTY
Due to natural heat emission by tubes, the amplifier is not recommended for continuous use
for more than 8 hours. After that time it is advisable to turn off and cool down the device for
minimum time of 1 hour. Protect the power cord from being walked on, pinched or
overheated (e.g. by the tubes).
DEVICE VENTILATION
The amplifier was manufactured and tested to the highest quality standards.
The warranty covers defects in material or workmanship for 36 months (tubes for 6
months), from date of purchase. Our limited warranty is void if the product is returned with
tampered labels, any alternations or in case of improper use. To request warranty service,
please provide sales receipt / document of purchase and description of the problem. Product
shipping is at buyer's expense.
GENERAL SAFETY INSTRUCTION - READ BEFORE FIRST USE!
Proper ventilation provides long lifetime of the amplifier. Upper and lower cover are
equipped with ventilation holes which guarantee a free airflow. Bottom ventialation holes
provide cool air into the device case, which flows through it and escapes at the top cover. Do
not obstruct the airflow around the amplifier. Allow at least 30cm(12 inches) free space
above the tubes and 10cm (4 inches) for the rear and sides. Do not place the device on any
other heat source. All ventilation openings should remain uncovered during operation of the
amplifier.

ENVY HEADPHONE AMPLIFIER
The Envy amplifier is a Single Ended class A headphone tube amplifier, built around the
famous 300B tubes, with transformer coupled output, designed to handle any kind of planar
magnetic or dynamic headphones with the impedance range between 16 to 600 Ohm.
Before turning the amplifier on for the first time, please install the tubes in the sockets, as
described on the illustration. Take care while installing the tubes, ensure the pins fit
appropriate holes in the socket. New amplifier requires a break-in period which takes place
during normal use of the device. Please note that the optimal sound quality will be reached
after approximately 50 hours of operation. In day to day use, tubes reach their operational
temperature after 15 minutes from powering on the device. All tubes must be installed
before turning on the amplifier. Never place the unit in an unstable location. A device may
fall, causing serious personal injury or death. Only use furniture that can safely support the
device. Ensure that the amplifier is not overheating the edge of the supporting furniture. Do
not place the device on tall furniture without anchoring the furniture. Do not place the
amplifier on cloth or other materials that may be located between the unit and supporting
furniture. Keep away the device from the reach of children.
