System Overview

The NUX B-7PSM is a wireless personal in-ear monitor system with automatic RF environment scan, 5.8GHz interference-free broadcasting frequency, and 24-bit / 40kHz  high-quality STEREO audio transmitting. It quickly finds a clean wireless channel and automatically assigns it. The B-7PSM offers a super low latency of less than 5.5ms and  has an operation range of 90 feet when unobstructed between the Receiver (RX) and Transmitter (TX). (The operation range is around 10 meters when obstructed). It’s a  super light-weight wireless, mini-compact system designed to clip on & go. The TX features a 1/8” TRS plug (you can use the included adaptor to convert to 1/4”), broadcaster- grade audio via 5.8GHz digital transmission to the compact RX. The RX’s clip design can easily fit to your shirt, belt, or guitar strap. And, with our newest  automatic frequency hopping technology, B-7PSM is reliable and stable while you perform on stage.
Note: When coupling multiple B-7PSM systems, please turn on 1 set first, pair it, and then turn on the other sets sequentially.
Note: For best results the TX should be at least 1 meter above the ground, 2 meters away from Wi-Fi routers and wall or metal surfaces to minimize reflections.
The user-friendly matching system makes it easy to use, just turn ON both wireless units (TX & RX), then it will be paired within a couple of seconds. Each wireless set has a  unique pairing algorithm, it automatically detects each other and configures their own IDs. The signal never interferes with any other wireless including the Wi-Fi signal. Recommended: Please stay 2 meters (6 feet) away from the Wi-Fi router for the best results.

How to Operate

Product interface

Power On/Off
Push and hold the power button for 2 seconds to turn ON the TX and RX.
Battery status
Before it gets paired automatically, you can see TX’s and RX’s battery status; if the LED indicator: *The B-7PSM can work up to 4 hours when fully charged.

Paired automatically
After 2 seconds, it will be paired automatically, and the TX’s LED status will blink GREEN.
B-7PSM will detect the best channel in the 5.8GHz frequency band, if the transmitter and receiver get paired, TX’s LED indicator will show GREEN. If the RX doesn’t  receive the signal, the RX’s LED indicator will flash RED. Since the RX receives the signal, the LED indicator will show GREEN.

Plug in the TX to a live or personal mixer, and turn on the TX (LED indicator will show GREEN.) Then connect your in-ear buds with the RX, turn on the RX to pairwith  the TX. The LED indicator will besolid GREEN. Now it’s ready to go.
Note: Be careful! Do not put the in-ear buds in your ears before you start to adjust the volume, it may hurt your ears if the volume is too loud.

Volume control

You can adjust the RX volume in 0.5db increments with the + and — buttons. The maximum volume is OdB, and the minimum is -64dB. Holding down the + or — button  can increase or decrease the volume quickly. The B-7PSM offers STEREO audio transmission, so it’s perfect to work with professional personal mixers to pan the tracks as  you want on stage or in the studio during rehearsals and live performances. The B-7PSM features premium sound quality with a 92dBA dynamic range and 20~19KHz frequency response.
Note: We recommend you use headphones or in-ear buds with a 16~32Q impedance for the best experience. You can charge the RX and TX units with the rechargeable  storage case, or by using the USB-C cable to charge. Both units can work while charging just in case.

Manually repair the RX and TX

The B-7PSM is already ID matched prior to shipping, but if you want to pair a different transmitter or receiver, please follow the steps to re-set the ID match.

• Turn off the TX & RX.
• Hold the power button of the TX and RX for more than 8 seconds, then it will enter to ID match status.
• When the TX’s LED shows GREEN, it finishes ID match and enter to normal work status.
  NUX offers various 5.8GHz wireless systems, you can use up to 10 systems simultaneously in one space. To prevent noise or interference issues, please avoid using other wireless systems together with NUX systems.

Charge

Rechargeable storage case
Charging the storage case: Connect the USB-C cable to the storage case’s USB port, use 5V/ more than 2A adaptor to charge. It will take around 4 hours to fully charge the  storage case.
