System Overview
INTRODUCTION
The Linn 328A is a fully active, 4-way, self-powered reference
monitor designed for professional audio applications where
accurate, revealing and realistic playback is essential.
Employing unique Linn playback technology, the 328A offers high
power, low colouration, low resonance, low distor tion and
exceptionally good low frequency response for the size of
enclosure.
HIGH SOUND PRESSURE LEVEL WARNING
Linn monitors are capable of generating high sound pressure levels
(SPL). Your hearing can be damaged by exposure to high SPL for an
extended period of time. Therefore we recommend that you use an
integrating type sound level meter to measure your exposure to SPL
while using these monitors, and that you limit your exposure to
within that recommended by your national health authority.
It is not sufficient to rely on your own judgement concerning SPL
when working with high quality monitors because your perception of
SPL is dependent on the amount of distor tion introduced by them.
Because this distor tion is ver y low in the Linn 328A, you can be led
into believing the SPL is lower than it actually is and hence risk
exposure to damaging levels.
CELLPHONE WARNING
Cellular telephones should not be placed in close proximity to this
monitor due to the possibility of damage to the monitor, the
cellphone, or both caused by electromagnetic interaction.
APPLICATIONS
The 328A is suitable for the most exacting, high resolution audio
monitoring applications.
The unit’s compactness and low-profile silhouette give excellent
working visibility, making it an ideal reference tool for professional
music, broadcast, post-production and mastering applications.
UNPACKING
Your 328A Reference Monitor comes packed in a box with the
following accessories:
• one mains lead
• this manual
The 328A monitor is heavy (45 kg) and must therefore be handled
using appropriate precautions to avoid the possibility of personal
injur y. It should always be lifted and handled by two people while
unpacking or repacking and during subsequent positioning
operations.
We recommend you retain the packaging for reuse in case you
need to transpor t the unit at any time.
INSPECTION
Your 328A left the factor y in per fect condition but it is possible
damage may have occurred in transit. After unpacking your monitor,
and before connecting to mains power or other equipment, inspect
the monitor for such damage. If damage is found, immediately
contact the carrier for advice on their claims procedure.
VOLTAGE SELECTION
Voltage selection is not needed. Your 328A is factor y set to operate
from your local mains supply. The mains lead supplied may be
fitted with a fused plug according to local regulations. If this is the
case, always replace this fuse with another of the same type and
rating.
The 328A Reference Monitor must always be ear thed when
connected to mains power. Use the ear thed moulded mains
lead supplied. Never use an unear thed plug or adapter with
this unit.
