{"product_id":"shure-adx-hh-606-663-mhz","title":"Shure ADX2\/SM58 – Axient Digital Handheld Transmitter (K54, 606-663 MHz)","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Shure ADX2\/SM58 is a handheld wireless microphone transmitter built for commercial AV deployments that require dependable RF performance in the 606-663 MHz (K54) band. Pairing the SM58 cardioid dynamic capsule with the Axient Digital wireless platform, this transmitter is the right choice for integrators and facilities managers specifying a commercial-grade handheld wireless microphone system for regions or coordination zones where the K54 range is the assigned or preferred spectrum. It is functionally identical to its 470-616 MHz and 941-960 MHz siblings in this product line, differing only in RF tuning range, so system designers can standardize on the ADX2\/SM58 platform while matching frequency coordination requirements project by project. Typical use cases include conference room and boardroom audio, house of worship reinforcement, and government or broadcast facilities operating under K54-band frequency coordination.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe ADX2\/SM58 combines Shure's Axient Digital wireless engine with the industry-standard SM58 capsule, giving AV integrators a handheld wireless microphone transmitter suited to conference room, boardroom, and house of worship installations that also serves broadcast and large-venue commercial deployments. Operating in the 606-663 MHz (K54) frequency band, this unit is intended for installations and markets where that specific tuning range is required for spectrum coordination or regulatory compliance — a key consideration for procurement teams sourcing equipment across multiple regions or venues. The transmitter offers selectable RF output power of 2, 10, or 40 mW, letting integrators balance coverage against battery runtime and RF density in a given room. Standard and High Density transmission modes give system designers flexibility for deployments ranging from a single-room commercial meeting space to a multi-channel broadcast studio or auditorium requiring a higher channel count within a limited spectrum footprint.\u003c\/p\u003e\n\u003cp\u003eOnboard AES 256-bit encryption addresses the data-security requirements common in government spaces and other sensitive commercial meeting environments where unauthorized RF interception is a concern. ShowLink remote control allows an AV technician or operator to adjust gain, RF power, and other transmitter parameters in real time without physically handling the microphone, which is useful during all-hands meetings, training sessions, or live events where the presenter cannot pause for adjustments. The cast aluminum, moisture-resistant housing and backlit LCD display (showing battery status, channel, group, and signal strength) are built for the wear and tear of daily use in commercial rack-mount AV systems and touring inventory alike. Rechargeable SB920A battery operation, combined with external charging contacts, supports the daily-turnaround workflows integrators rely on for corporate AV, house of worship, and training room installations where the transmitter needs to be ready for the next session with minimal downtime.\u003c\/p\u003e\n\n\u003ch2\u003eKey

the ADX2\/SM58 compatible with other Axient Digital receivers?\u003c\/strong\u003e\u003cbr\u003eYes. The ADX2\/SM58 is designed to pair with Axient Digital receivers, such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/shure-adx5d-a-adx5d-portable-receiver-470-636mhz\"\u003eShure ADX5D portable receiver\u003c\/a\u003e, provided the receiver is tuned to a compatible band. Always confirm frequency band compatibility before ordering, since this SKU is specifically the 606-663 MHz (K54) version.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the frequency band matter when specifying this transmitter?\u003c\/strong\u003e\u003cbr\u003eRF spectrum allocation varies by region and by local coordination requirements. The 606-663 MHz (K54) band is a distinct tuning range from the 470-616 MHz (G57) and 941-960 MHz (X55) versions of this same transmitter, so integrators must match the band to the deployment location and any existing wireless inventory to avoid interference or non-compliant operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this transmitter be used with existing SM58 wireless capsules or accessories?\u003c\/strong\u003e\u003cbr\u003eThe ADX2\/SM58 ships with an integrated SM58 capsule as part of the transmitter body. It is not a capsule-only accessory, but it shares battery and charging accessories with other ADX2-series transmitters, including the Shure SB920A rechargeable battery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is required for installation in a rack-mount AV system?\u003c\/strong\u003e\u003cbr\u003eThe transmitter itself is a handheld device and does not rack-mount; it works alongside a rack-mounted or portable Axient Digital receiver. Integrators should plan antenna placement, RF coordination, and receiver rack space as part of the overall AV system design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this transmitter support remote configuration during a live event?\u003c\/strong\u003e\u003cbr\u003eYes. ShowLink remote control lets an operator adjust RF output power, gain, and other parameters in real time from a compatible access point without interrupting the presenter or performer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the battery last, and what charging accessories are needed?\u003c\/strong\u003e\u003cbr\u003eThe transmitter runs up to 9 hours on a fully charged SB920A rechargeable battery. It supports docked charging via external contacts, so a compatible Shure charging station should be included in the system design for daily-turnaround use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat warranty and support does Shure provide on this transmitter?\u003c\/strong\u003e\u003cbr\u003eShure's standard manufacturer warranty applies to the ADX2\/SM58.
