Description

Overview

The MTB40S is a compact and lightweight plug-on transmitter featuring a limiter, selectable 10/50/100 mW output power, and two different companders, as well as strong protections against noise and intermodulation.

The Ultrasonic Narrowband technology,protects against ultrasonic interference from lights. camera range trackers and other sources with a dedicated 70 dB filter. Narrowband operations use half of the bandwidth and have an extra 50% range over the previous generation. A compatibility mode is available for use with legacy Wisycom systems.

The XLR3F connector is designed with a locking collar for an extremely tight noiseless fit.

The MTB40S provides 48V phantom power and is powered by two AA batteries.

The user-selectable compander modes are ENR (noise optimized) and ENC (voice optimized).

LED indicators:

Wireless transmission status: GREEN on/RED off
Battery lifetime status: GREEN steady (> 25%), slowly blinking (< 25%), quickly blinking (<12%)
Modulation peek (if activated & the limiter is disabled): RED
Limiter into action: Blue

Consumer Alert

Starting in 2017, the 617-652 MHz and 663-698 MHz frequencies are being transitioned by the Federal Communications Commission (FCC). Users of wireless microphone devices that operate in any portion of those frequencies must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
