AXT400 Dual Channel Receiver

Overview

The AXT400 Dual Channel Receiver combines advanced analog and digital technology to deliver exceptional RF and audio performance. The receiver features ShowLink™ Remote Control for real-time transmitter adjustments, Frequency Diversity mode for seamless dual-frequency operation, and Interference Detection & Avoidance. It offers up to 228 MHz of wideband tuning and supports AXT and UHF-R series transmitters. Connectivity options include transformer balanced audio outputs, AES3 digital audio output, RF Cascade ports and dual Ethernet ports for networked control and monitoring via Shure Wireless Workbench 6 software.

• Comprehensive real-time remote control of a linked transmitter when used with the AXT610 ShowLink Access Point.

• Detects the presence of an interfering analog or digital signal and avoids it by switching to a ‘backup’ frequency deployed by the AXT600 Axient Spectrum Manager, either manually or automatically.

• Frequency diversity provides seamless audio in environments where there is a risk of dropouts or interference by using transmission from a single audio source on two independent radio frequencies.

• Up to 228 MHz tuning bandwidth accommodates multiple transmitter bands, providing flexibility and simplifying receiver inventories.

• The AXT400 Receiver shares information with other system components via Ethernet networking, enabling advanced features such as remote control of transmitters and management using WWB

• RF Cascade Ports share RF signal with up to 5 receivers within the same frequency band.

• Compatible Transmitters :

• AXT100 Bodypack Transmitter,

• AXT200 Frequency Diversity Handheld Transmitter

• UR1 Bodypack Transmitter

• UR1H Bodypack Transmitter

• UR1M Micro-Bodypack transmitter

• UR2 Handheld Transmitter
