NUX B-7PSM Wireless In-Ear Monitoring System

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 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 Ω impedance for the best experience.

Note: B-7PSM is designed for band rehearsals and live performances, prioritizing the best possible STEREO experience. You’ll enjoy the product and the experience it provides, while it may not be suitable for personal silent practice.

While the B-7PSM is a STEREO IEM solution, you can use it in a mono environment as well if needed. Simply use a 1/4″ MONO to 1/8″ STEREO adapter (to split the mono signal from a 1/4″ Output into both channels of B-7PSM’s 1/8″ Stereo Input), then you can get a mono signal that can be heard in both the left and right channels.

Caution: Please consult the seller of your adaptor before making the connection, in order to avoid any device damage.
