Chiayi Nanmen Presbyterian Church Opened New Chapels with MIPRO Wireless Systems
 



The main hall of Chiayi Nanmen Church

The Chiayi Nanmen Presbyterian Church started preaching Christianity in 1967. After several relocations, the current site was purchased in January 2008. As the number of church member increased, the original chapel was unable to accommodate the expanded congregation and a new church was planned in 2014 with a floor area of 1,400 sq m with different chapels for both Taiwanese and Mandarin Chinese languages. The new church which can accommodate 400 people was completed at the end of 2018.

The new building has three storeys. The main hall is on the second floor and the deputy hall and the fellowship hall on the first floor. AV engineer Daniel Ku, who is in charge of planning and operating audio visual systems for the new hall, said, “The building was not pre-wired for wired microphones. Therefore, all the microphones must be wireless.”

Ku selected wireless microphone and wireless portable public address systems with advanced wireless interlinking speakers from Taiwan-based Mipro. These were installed with 16 channels in the main hall, 14 channels in the deputy hall and two channels in the fellowship hall.
 
In the main hall, a 16-channel wireless system includes one ACT-848 quad-channel digital receiver, three ACT-74 quad-channel true diversity receivers, one AD-708 auto gain control antenna divider, and two AT-70W omnidirectional antenna. The ACT-848 is paired with four TA-80 plug-on transmitters, one for piano, one for bass, two for choir; three ACT-74 are paired with six ACT-70HC rechargeable wireless microphone for talking or singing and six ACT-70TC rechargeable bodypack transmitters, two of which are installed inside the BC-100 desktop conference microphone base with MM-205 gooseneck microphone, which forms a pair of podium microphone. Another one is used with the MU-53L lavalier microphone for the pastor, and the other three are used for electronic drums, an electric guitar, and an acoustic guitar.



In the deputy hall, a 14-channel wireless system includes one ACT-848 quad-channel digital receiver, one ACT-72 dual-channel true diversity receiver, two ACT-2414 quad-channel 2.4 GHz digital receivers, AD-708 auto gain control antenna splitter and two AT-70W omnidirectional antennas. The ACT-848 is paired with three TA-80 plug-on transmitters, one for the piano, two for the shotguns, and the fourth channel paired with the ACT-80TC for picking up the instruments. The ACT-72 is paired with two sets of BC-100 and MM-205 to form a pair of podium microphone; two ACT-2414 with five ACT-24HC rechargeable handheld wireless microphones and three ACT-24TC rechargeable bodypack transmitters are used for speaking, singing and the instruments.



In the fellowship hall, one MA-909 wireless mixer is equipped with two units of receiving modules and one unit of MT-92 transmitting module, and two units of MA-303 wireless portable PA systems. Two units of MRM-70B receiving modules can receive the signal of the ACT-32H handheld microphone, and transmit the mixed audio signal through the MT-92 to two MA-303SB for receiving and public addressing.



The main hall signal is transmitted to the deputy hall and the fellowship hall in wireless interlinking method.

“Each space has its audio system operated independently. However, the audio and video signals of the main hall must be connected to the deputy hall and the fellowship hall for the parishioners can watch simultaneously the live feed from the main hall. We still use the wireless method to solve it. All the signals of the main hall input to the mixer, and then transmit through the MT-92A interlinking transmitter to the ACT-311B in the deputy hall and the fellowship hall respectively, and then connect to the mixer, thus the daisy chain of the audio system is completed,” said Ku.

Ku said, “the MA-909 is equal to a multifunctional mixer. It can transmit signals to the MA-303 independently, or use the ACT-311B to receive the MT-92A signal from the main hall in the second floor and output to the mic-in of the MA-909, and then the mixed signal is transmitted to the MA-303 via the MT-90. The MA-909 can be used independently or used in conjunction with the 2F main hall. Only MIPRO has this kind of product and application.”

He added: “Since the wireless system is used extensively and there are no worries about the wiring, the installation is simplified, and the working hours are greatly reduced. The installation of the entire audio systems only took me two days.”

The Chiayi Nanmen Church held its church dedication service during Christmas 2018. The wireless and PA sound systems have performed well and reliably as expected, and no interference, signal dropouts or other problems were reported.
