IMPORTANT SAFETY INSTRUCTIONS

Exposure to extremely high noise levels may cause permanent hear-

ing loss. Individuals vary considerable in susceptibility to noise-induced

hearing loss, but nearly everyone will lose some hearing if exposed to

sufficiently intense noise for a period of time. The U.S. Government's

Occupational Safety and Health Administration (OSHA) have specified the

permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits

could result in some hearing loss. To ensure against potentially danger-

ous exposure to high sound pressure levels, it is recommended that all

persons exposed to equipment capable of producing high sound pressure

levels use hearing protectors while the equipment is in operation. Ear

plugs or protectors in the ear canals or over the ears must be worn when

operating the equipment in order to prevent permanent hearing loss if ex-

posure is in excess of the limits set forth here.

LIMITED 5 YEAR WARRANTY

AVANTONE PLANAR's are warranted by Avantone Pro to be free from

defects in materials and workmanship for the period of 5 YEARS to the

original purchaser. In the event of such defects, the Avantone Pro product

will be repaired without charge or, at our option, replaced with a new one

if delivered to Avantone Pro prepaid, together with a copy of the sales slip

or other proof of purchase date. The warranty excludes problems due to

normal wear, abuse, shipping damage or failure to use the product in ac-

cordance with the specifications.

All speaker systems are vulnerable to damage from sustained amplifier

clipping. This can be described as a distortion of the signal caused by the

amplifier running out of headroom. Heat will then be generated in the

voice coil of the driver beyond the heat handling capabilities of wire and

glue. At some point the voice coil will burn, causing the speaker to sound

very distorted; eventually the driver will stop working.

All parts and labor are covered under this Limited Warranty. However, if it

is determined by AVANTONE PRO that the voice coil was burned due to

sustained amplifier clipping, we reserve the right to charge the customer

for the cost of the repair, since this is considered abuse.

Avantone Pro shall not be liable for damages based upon inconvenience,

loss of use of the product, loss of time, interrupted operation or com-

mercial loss or any other damages, whether incidental, consequential, or

otherwise. This warranty gives you specific legal rights, and you may have

other rights, which will vary from state to state.

This warranty is not transferable.

INTRODUCTION

Planar magnetic audio drivers have been around for decades. In au-

diophile hifi loudspeakers and in headphones. Loudspeakers, although

praised for midrange and high frequency performance, never got a lot of

traction in hifi due to the lack of bass coming from these systems. How-

ever, in an enclosed listening space like a headphone this is not an issue.

The advantage of a planar system over a traditional voice coil and cone is

simply mass. The planar membrane is much lower mass than a traditional

cone system. Even in modern headphones, using light-weight materials,

there is still a voice coil attached to the moving cone.

The difference in the mounting system also yields a significant improve-

ment in distortion and transient response. Even though both are edge

suspended, the behavior of a circular surround is much different than a

planar membrane. The front and back magnets provide an equal and

opposite push/pull instead of relying on the mechanical spring of the sur-

round to assist in the return to neutral position.

The attach point of a voice coil also can affect the distortion artifacts pres-

ent in a moving coil type speaker. If there is any imbalance in positioning in

the gap, it will induce unwanted behavior. Any imbalance in mass caused

by alignment, glue, or other considerations can also cause problems. Pla-

nar speakers by their nature are immune to these and other issues.

Combining modern materials – neodymium magnets and super thin

membrane materials, we are now able to build cost-effective systems

that have phenomenal frequency and transient response. Super low

mass and reasonable excursion allow for one of the most precise play-

back systems known.

The Avantone Pro PLANAR is the culmination of years of research and au-

diophile experience in the design team. A passion for accurate, yet musical

tonality, exquisite response to attack times, and a large format membrane

gives a full range experience like no other.

We have combined our passion for sonic excellence and affordability with

a beautiful vintage look, made of robust materials to provide both a beau-

tifully crafted headset and a truly impressive sonic experience.

The Avantone Pro PLANAR is the ultimate in playback and audiophile lis-

tening. You have never heard anything with the clarity, accuracy, range

and response in a headphone before.

Thank you for purchasing the Avantone Pro PLANAR.

ENGINEERING OBJECTIVES

The Avantone Pro PLANAR Studio Reference Headphones are designed

to be dynamic, high SPL, high resolution, full-range playback monitors.

We included custom engineered, large area diaphragm, precise, no-com-

promise drivers in a beautiful, comfortable format that complements

modern production environments.

These are an open back design, allowing for the clearest transient re-

sponse, phenomenal mids and highs, and a listening experience like no

other.
