Audix NCHH Novacore UHF Digital Handheld Transmitter w/Hypercardioid Capsule

About: Audix NCHH Novacore UHF Digital Handheld Transmitter w/Hypercardioid Capsule

The NCHHTH bundles the AUDIX Novacore NCHH digital handheld transmitter with the NCTH Tight Hypercardioid Wireless Capsule — a complete, performance-ready wireless handheld built for loud stages, high-SPL environments, and any application where maximum feedback rejection and precise pickup control are the priority. The NCTH's tight hypercardioid pattern delivers narrow off-axis rejection and strong gain-before-feedback headroom, with voicing consistent with the AUDIX OMX series and the natural transient response that AUDIX capsules are known for. 

• NCTH tight hypercardioid capsule — maximum feedback rejection for loud stages and high-SPL environments, voiced from the AUDIX OMX series
• AES-256 encryption with one-touch IR sync; 48 MHz tuning range (494–542 MHz); <3 ms latency
• Switchable RF output: 1 mW / 10 mW; three selectable mute modes (Standard, Auto, Bypass)
• Standard "S" thread capsule mount — swap to NCEC Extended Cardioid at any time, no tools required
• 9+ hour runtime on 2x AA alkaline or 1x NCLB rechargeable lithium-ion; USB-C charging built in

The NCHH transmitter delivers AES-256 encrypted UHF digital transmission across a 48 MHz tuning range with less than 3 ms latency. One-touch IR sync pairs to any Novacore receiver in seconds. On-board controls provide access to variable input gain, low-cut filter, limiter, RF power level, and three selectable mute modes — all accessible via the front-panel LCD and the controls beneath the battery cover. 

The NCHHTH operates on 2x AA alkaline batteries or 1x NCLB rechargeable lithium-ion battery with 9+ hours of runtime, with USB-C charging built into the transmitter body. The NCTH capsule is interchangeable — swap to an NCEC Extended Cardioid at any time using the same "S" thread mount, with no tools required.
