And it ensures the quality and durability by acquiring KS certification in the Korea's first.

Inter-M acquired a KS certification for speaker system as the first's Korea speaker system manufacturer.The relevant certification is given to the factory of Korea speaker system manufacturer. It ensures KS standard observance for all speakers in the certification items manufactured at the relevant facilitiesFurthermore, 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.

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 verification 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 difficult 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 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.

It was used and designed with matching the volume of amplifier 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 amplifier and speaker than the existing amplifier output to make a good quality of music broadcasting and clearer announcement. In comparision with the volume of the speaker output, the output of amplifier should be designed minimum over 2 times of the output to make the sound quality and sound articulation.
