The M170 Series transmitter is offered in five versions. The standard model is the M170. The M170-LS, M170-XLR, M170-BGO, and the M170-CTM are modifications of the standard M170.
The M170 and M170-LS transmitters use the microphone cord for the antenna. The M170-XLR uses the hand-held microphone for the antenna. This feature eliminates the need for the “dangling wire” antenna found on many transmitters. The walnut body of the M170-CTM is securely attached to a machined aluminum plate which serves as the antenna ground plane and as mass to absorb vibration. The M170 Series transmitters use a crystal controlled oscillator and temperature compensation circuitry to ensure that the transmitter does not drift over time or with age.
