5.8 GHz Wireless In-Ear Monitoring System
CUT THE CORD. BE IN COMMAND!
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 / 40 kHz high-quality STEREO audio transmitting.
From any position. On any stage. Hear every note in detail with NUX B-7PSM in-ear monitoring system.
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
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.
he 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 WiFi* signal.
*Recommended: Please stay 2 meters (6 feet) away from the Wifi router for the best results.
A Loud Stereo Phone Preamp
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 pair with the TX. The LED indicator will be solid GREEN. Now it’s ready to go.
Caution: 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.
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 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 20~19K Hz frequency response.
Note: Short press the power button of the RX to return to the default volume setting. It may be too loud if
the in-ear buds are very sensitive. Please turn down the mixer’s volume and increase it carefully.
Note: We recommend you use headphones or in-ear buds with a 16~32 O 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.
