2ARN3-41601BASEIntercom System Master Console

User Manual 用户手册 WiTalk BASE Intercom System Master Console 通话系统主站控制台 1 Product Prole 1.1 System Overview WiTalk BASE is a full-duplex wireless intercom system designed for professional collaboration scenarios such as lm and television production, live events, and on-site coordination. The system supports simultaneous talk and listen for multiple users without push-to-talk activation, meeting the real-time collaborative communication needs of teams in complex on-site environments. 1.2 System Capabilities • A single WiTalk BASE station can connect up to 16 terminal devices, and larger-scale deployments can be achieved through multi-base station cascading. • The system supports up to 8 independent talk groups, meeting the parallel communication needs of multiple groups such as the Director Group, Camera Group, Lighting Group, and Audio Group. • The communication range between the base station and headsets can reach up to 500 meters under unobstructed, line-of-sight conditions. Actual communication range may vary depending on on-site obstructions, installation height, electromagnetic environment, and usage conditions. • WiTalk BASE stations support wired cascading via LAN, allowing the system to scale up to 4 base stations with a maximum total capacity of 64 terminal devices. • In multi-base station coverage scenarios, connected terminals can automatically roam and switch between di erent base station coverage areas. 1.3 Audio Performance • Supports wideband voice communication with a 16 kHz audio sampling rate, frequency response range of 100 Hz–7 kHz, signal-to-noise ratio >55 dB, and distortion rate <1%. • Employs ENC multi-microphone array and noise reduction algorithms to suppress background interference in complex noise environments, thereby improving speech intelligibility and communication e ciency. • Adopts a 1.9 GHz DECT wireless transmission solution with strong anti-interference capability. Speci c available frequency bands, certication requirements, and sales versions are subject to target market regulations and actual shipping versions. 1.4 Interfaces and Expansion • The base station is equipped with LAN, 4-Wire, UAC, 3.5 mm, and other interfaces for audio connectivity and signal interaction with mixing consoles, two-way radios, computers, and other devices. • Supports DHCP and static IP network con guration for convenient Web management, system con guration, and maintenance across dierent LAN environments. • Supports audio interconnection with certain third-party wired intercom or audio systems via the 4W interface. Compatibility depends on the remote device's interface de nition, pin-out, and level settings. 1.5 Power Supply and Management • Supports V-Mount / G-Mount battery and DC adapter power supply to accommodate di erent on-site deployment requirements. • Supports con guration and management via the base station's local interface, Web interface, and App. • The base station supports local and online rmware upgrades; headset rmware update methods depend on the speci c model and current system conguration. Please refer to the corresponding chapter for detailed instructions. 2 Packing List 2.1 Kit Description WiTalk BASE is available in multiple kit con gurations, and the package contents may vary depending on the model. Please refer to the actual purchased version and the packing list card included in the package. 2.2 Package Contents • WiTalk BASE Station • Single-Ear Headset (con guration varies by kit version) • Dual-Ear Headset (con guration varies by kit version) • Helmet Headset (con guration varies by kit version) • Headset External Battery • 10-Slot Charging Case • Over-Ear Cushions • On-Ear Cushions • Single-Ear Head Pad • Microphone Windscreen • USB Type-A to Type-C Cable • Base Station Antenna • User Manual • Warranty Card 3 Base Station Structure and Interface Description 3.1 Base Station Appearance and Component Names The WiTalk BASE station consists of the following main components: Bluetooth Indicator Light IP Status Indicator Light Display Function Button Area Handle Antenna Connector and Antenna Reserved Expansion Port (not for user operation in the current version) RJ45 LAN 1 Port RJ45 LAN 2 Port 3/8" Mounting Screw Hole 5/8" Mounting Interface USB-A Port USB-C Port DC Power Port 3.5 mm Audio Port RJ45 4W Audio Port Locking Knob V-Mount / G-Mount Battery Plate Mounting Position 3.2 RJ45 LAN 1 / RJ45 LAN 2 Interface Description Pin-out The RJ45 LAN 1 / RJ45 LAN 2 ports are used for LAN cascading and system synchronization between WiTalk BASE stations. These ports are primarily used for audio, group, and system management data transmission in multi-base station expansion scenarios. Standard Pin-out PIN 1 Transceive Data+ PIN 2 Transceive Data- PIN 3 Receive Data+ PIN 4 CLK 100Hz+ PIN 5 CLK 100Hz- PIN 6 Receive Data- PIN 7 CLK GND PIN 8 CLK GND Usage Instructions These ports are only intended for system interconnection between WiTalk BASE stations. It is not recommended to use these ports as general network switch ports, PoE ports, or other general-purpose RJ45 ports. When cascading base stations, it is recommended to use CAT5e or CAT6 shielded cables to reduce the impact of external electromagnetic interference on system stability. It is recommended that the length of a single cable segment does not exceed 100 meters. Precautions LAN cascading is a digital signal interconnection and only supports communication between WiTalk BASE stations. Do not connect to routers or other third-part y devices. For multi-base station systems, please refer to Section 4.5 for network role con guration. 3.3 RJ45 4W Audio Interface Description The RJ45 4W audio port is used for 4W audio interconnection between WiTalk BASE and similar systems or certain third-party wired intercom/ audio systems. The original documentation clearly states that this interface supports both standard and crossover pin congurations and is used for internal WiTalk system connections or interfacing wi…

According to KDB 447498 D04 Interim General RF Exposure Guidance MPE-Based Exemption: General frequency and separation-distance dependent MPE-based effective radiated power(ERP) thresholds are in Table B.1 [Table 1 of § 1.1307(b)(3)(i)(C)] to support an exemption from further evaluation from 300 kHz through 100 GHz. R is the minimum separation distance in meters f = frequency in MHz For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Bay Area Compliance Laboratories Corp.
