It is ideal for venues requiring robust and flexible audio distribution.
ส่วนประกอบของระบบ
The LCS-120-01 system includes the following components:

รูปที่ 1: เกินview of the Listen Technologies Wi-Fi/RF Base System components.
- One (1) MX5-1AE 2 Channel (mono) Wi-Fi Server: This unit (top left in Figure 1) enables audio broadcasting over Wi-Fi frequencies (2.4/5.0 GHz). It is compatible with Wi-Fi IEEE 802.11 standards and can support up to 1,000 simultaneous users. It connects to the venue's existing LAN via an RJ45 Ethernet connection.
- One (1) LW-100AE Venue Awareness Kit: Used for configuring and managing the Wi-Fi system.
- One (1) LT-803-072-P1 Stationary 3-Channel Transmitter Package (72 MHz): This transmitter (middle in Figure 1) broadcasts audio over the 72 MHz RF frequency. It can operate on channels A (72.100 MHz), E (72.900 MHz), or H (75.900 MHz). It features two mixing audio inputs and adjustable output power.
- One (1) LPT-A107-B Dual RCA to Dual RCA Cable 6.6 ft. (2 M): For connecting audio sources to the transmitter.
- Two (2) LR-200-072 Standard 3-Channel Receiver (72 MHz): These portable receivers (bottom right in Figure 1) allow users to receive audio broadcasted over the 72 MHz RF frequency.
- Two (2) LA-164 Ear Speaker: These ear speakers (bottom middle in Figure 1) connect to the LR-200-072 receivers for audio output.
- Two (2) LA-166 Neck Loops: These neck loops (bottom left in Figure 1) provide an inductive coupling to hearing aids equipped with a T-coil, allowing direct audio reception.
คำแนะนำการตั้งค่า
- การเชื่อมต่อไฟฟ้า: Connect the power adapters to the MX5-1AE Wi-Fi Server and the LT-803-072-P1 Transmitter. Ensure they are plugged into a stable power source.
- การเชื่อมต่อแหล่งกำเนิดเสียง: Use the LPT-A107-B Dual RCA cable to connect your audio source (e.g., mixer, sound system) to the audio inputs on the LT-803-072-P1 Transmitter. The transmitter has two mixing audio inputs.
- Network Connection (Wi-Fi Server): Connect the MX5-1AE Wi-Fi Server to your venue's local area network (LAN) using an RJ45 Ethernet cable. This enables the Wi-Fi audio streaming functionality.
- Transmitter Channel Selection: On the LT-803-072-P1 Transmitter, select the desired RF channel (A, E, or H) using the channel select controls. Refer to the transmitter's display for confirmation.
- การเตรียมความพร้อมของเครื่องรับสัญญาณ: For RF users, insert the LA-164 Ear Speakers or LA-166 Neck Loops into the LR-200-072 Standard Receivers. Ensure the receivers have fresh batteries.
- Wi-Fi App Setup: Instruct users to download the free Listen Technologies app on their personal smart devices (phones, tablets). When launched, the app will automatically connect to the Wi-Fi server and display available audio channels.
- การทดสอบระบบ: Before full deployment, perform a test to ensure audio is broadcasting correctly on both RF and Wi-Fi frequencies. Verify audio clarity and signal strength in various areas of the venue.
