speaker. And it ensures the quality and durability by acquiring KS certication in the Korea's
rst.
Korea standard speaker (KS standard)
Inter-M acquired a KS certication for speaker system as the rst's Korea
speaker system manufacturer.
The relevant certication is given to the factory of Korea speaker system
manufacturer.

items manufactured at the relevant facilities
Furthermore, Inter-M speaker provides the durability and reliable quality to
user by adding the AES, CEA standard used in the domestic, international
market to test list apart from KS standard.
Thorough quality control
The only products passing a 5 test including a frequency response, harmonics, lumbers
are assigned with 'PASS' to provide a stable and equal quality in the market. The relevant
test is proceeded through the automation equipment and support the exact verication
about the products.

In case the emergency broadcasting speaker (90db SPL) is installed at intervals of 25m, listening the sound at the intermediate
position between speaker and speaker will get smaller about 14times (22db) than listening the sound at the bottom of speaker.
It is difcult to understand the noise as the sound is smaller than ambient noise(70dBA SPL)
Therefore, the spacing of the speaker installation should decrease under 15m to deliver the exact information.

The spacing of the ceiling speaker installation
The speaker for emergency broadcasting requires the higher
sound pressure when considering ambient noise increases
as growing the ventilation system lately and ambient noise
grows at emergency state.
The existing 3W speaker can't provide the appropriate
sound pressure as the clear broadcasting is possible by
making over 6dB of sound pressure comparing ambient
noise (70dBA SPL)
So the existing broadcasting is possible by installing the
speaker, which is possible to make the output of over 120W.

The combination between speaker and amplier
12W x 13 300W
It was used and designed with matching the volume of amplier and speaker output as the past PA system are consist of mainly
speech broadcasting such as a emergency broadcasting and announcement. But the recent PA system is used for mainly BGM
music in addition to speech broadcasting.
Therefore, it requires the higher output of amplier and speaker than the existing amplier output to make a good quality of
music broadcasting and clearer announcement. In comparision with the volume of the speaker output, the output of amplier
should be designed minimum over 2 times of the output to make the sound quality and sound articulation.
