GTD Audio 4x800 UHF Diversity Wireless Mic System - Reliable Range

In this review of the GTD Audio 4x800 system, the bottom line is simple: this kit is built for small to mid-size events and houses of worship that need reliable multi-microphone operation without a lot of interference headaches. The reviewer found the system provides notably clean sound and stable reception thanks to its true diversity design, and the combination of 800 selectable frequencies per channel with automatic scanning makes it easy to find a clear channel in crowded RF environments.

Key Features

• 800 selectable frequencies: Lets the user avoid local interference by choosing from many UHF channels for cleaner reception.
• True diversity operation: Uses two receiver antennas to reduce dropouts and improve signal reliability across a larger area.
• Automatic frequency scanning: Scans the local band to select a mostly interference-free channel, simplifying setup in busy RF environments.
• Automatic transmitter setup: Synchronizes transmitter and receiver channels quickly so users spend less time tuning and more time performing.
• Adjustable gain and Tone Lock squelch: Reduces feedback and unwanted noise while keeping the vocal level consistent.
• Extended wireless range: Practical range up to 450 ft (150 m) in open spaces for flexible placement of talent or presenters.

Who It's For

The GTD Audio 4x800 is best for event technicians, small touring acts, churches, and presenters who need up to four simultaneous wireless microphones and value signal reliability and sound clarity. It suits setups where several wireless systems may be used at once, since the system supports many selectable frequencies and can operate alongside other systems when configured correctly.

Those who require ultra-compact consumer-style units or professional broadcast features beyond basic diversity and scanning should look elsewhere, but anyone installing a sound system for ceremonies, lectures, rehearsals, or live performances will find this system a practical, cost-conscious choice.

Pros & Cons

Pros

• Reliable reception from the true diversity receivers reduces dropouts compared with single-antenna designs.
• Many selectable frequencies and automatic scanning make coexistence with other systems easier and improve overall signal quality.
• Automatic transmitter synchronization speeds setup and reduces operator error.
• Adjustable gain and Tone Lock squelch help control feedback and background noise in live environments.

Cons

• Setup ease is mixed for some users; the unit automates much of the process but the supplied instructions are sparse for first-time installers.

Frequently Asked Questions

Can multiple systems operate together?
Yes. The system offers many selectable frequencies and automatic scanning to help find clean channels so up to 20 sets can operate in the same venue when properly coordinated.

What is the practical range I can expect?
Range in open conditions is up to 450 ft (150 m); indoor range will vary with walls and RF obstacles but true diversity improves reliability.

Does it reduce feedback?
Yes. Adjustable gain and a Tone Lock squelch circuit help reduce feedback and limit unwanted noise when levels are set correctly.
