Inside the Design
The MegaVox 2 System 4 is a portable, battery-powered public address system designed for marching band rehearsals, athletic fields, sporting events, outdoor assemblies, military training, emergency announcements, and other applications requiring clear voice projection over large areas. Featuring one Anchor Audio MEGA2-U4 MegaVox 2 speaker with built-in Class 1 Bluetooth and two dual AnchorLink wireless microphone receivers, an SS-550 heavy-duty speaker stand, and a choice of four wireless microphones, this system provides convenient sound reinforcement for multiple speakers and presenters without requiring external wireless receivers. Anchor Audio rates the MegaVox 2 for audiences of approximately 1,000 people, depending on the environment and coverage requirements.
The MEGA2-U4 delivers 20W of rated power in both AC and battery operation, producing a maximum SPL of 119 dB at 1 meter with a frequency response of 400 Hz to 10 kHz (±3 dB). Its high-efficiency re-entrant horn driver provides strong, focused speech projection for announcements, instructions, and public address applications. The lightweight enclosure features an integrated carrying handle and speaker stand socket, while the included SS-550 heavy-duty speaker stand provides adjustable height and leg width for convenient elevated placement.
The MegaVox 2 features a built-in 12V, 5 Ah lithium iron phosphate (LiFePO4) rechargeable battery, providing 7+ hours of operation depending on usage conditions. The included RC-2 charger provides convenient battery recharging, with approximately five hours required for a full charge. Built-in Class 1 Bluetooth allows wireless audio streaming from compatible devices, while two integrated dual AnchorLink receivers operate in the 1.9 GHz DECT frequency band with automatic frequency management and a wireless microphone range of 300ft or more under ideal line-of-sight conditions. Together, the receivers support up to four compatible wireless microphones simultaneously.
For additional connectivity, the MEGA2-U4 includes two unbalanced 1/4" wired microphone inputs, a 1/4" line input for compatible external audio sources, and a 1/4" line output for connecting additional audio equipment. A separate 1/4" external speaker output can power an optional MegaVox 2 wired companion speaker, sold separately. Independent input level controls provide convenient adjustment of connected audio sources, while the built-in signal alert function helps attract attention before important announcements.
Choose from seven wireless microphone configurations featuring four WH-LINK handheld microphones, four HBM-LINK headband microphones, four LM-LINK lapel microphones, four CM-LINK collar microphones, or mixed configurations combining two handheld microphones with two headband, lapel, or collar microphones. Headband, lapel, and collar microphone options include the required WB-LINK wireless beltp ack transmitters. All seven configurations provide four wireless microphones for simultaneous operation with the MEGA2-U4's integrated AnchorLink receivers.
The WH-LINK handheld microphones and WB-LINK beltpack transmitters each operate using two AA alkaline batteries and provide approximately 6–8 hours of operation with fresh batteries, according to Anchor Audio's individual product specifications. Both transmitter types feature adjustable volume and mute controls. The MEGA2-U4 does not include an Anchor AIR transmitter; wireless transmission to Anchor AIR companion speakers requires a compatible transmitter-equipped model.
The MegaVox 2 System 4 is backed by Anchor Audio's 6-4-2 warranty, providing six years of coverage for the speaker system, four years for the rechargeable battery, and two years for wireless microphones and peripheral products, subject to the manufacturer's warranty terms.
