Nux B-7PSM 5.8GHZ Wireless Headphone Monitor System

Wireless Transmitter for Headphones

With this system, which provides clear and crisp sound transmission at 24-Bit resolution in the 5.8 GHz frequency band, you can gain the advantage of wireless use when performing in-ear monitoring on stage and in the studio.

It quickly finds a clear wireless channel and assigns it automatically. The B-7PSM offers super-low latency of less than 5.5ms and has an operating range of 100ft (30m) when there are no obstacles between the Receiver (RX) and Transmitter (TX). (Operating range is approximately 32ft (10m) when obstructed). This is a super-lightweight, wireless, mini-compact system designed to plug and go. The TX features a 1/8” TRS plug (you can use the included adapter to convert it to 1/4”), and the compact RX delivers broadcast-grade audio via 5.8GHz digital transmission. The RX’s clip design easily clips onto your shirt, belt or guitar strap. And with our latest automatic frequency-hopping technology, the B-7PSM is reliable and stable while you’re performing on stage.

Easy to Use

Thanks to the automatic pairing and connection feature, even if you use more than one of the same units in the same place, the signals will not interfere with each other and will work seamlessly.

Powerful Headphone Preamplifier

Plug the TX into a live or personal mixer and turn on the TX (LED indicator will show GREEN). Then connect your earbuds to the RX, turn on the RX to pair with the TX. The LED indicator will be solid GREEN. You can adjust the RX volume in 0.5db increments with the + and – buttons. The maximum volume is 0dB and the minimum is -64dB. Holding down the + or – button can quickly increase or decrease the volume. The B-7PSM offers STEREO audio transmission, so it is perfect for working with professional personal mixers to pan tracks as desired on stage or in the studio during rehearsals and live performances. The B-7PSM features premium sound quality with 92dBA dynamic range and a frequency response of 20~19K Hz. Note: For the best experience, it is recommended to use headphones or in-ear headphones with an impedance of 16~32 Ω.
