The Electro Voice SMP-2 is a SoundMate Portable Listening System that is designed composed of different devices for ease of use of the user. The Electro Voice SMP-2 system is composed of:

PST-170 Belt Pack Transmitter
The PST-170 Belt Pack Transmitter is able to be set to any of the 17 channels, those can be seen displayed on the backlit LCD, and it is able to operate of 72-76 MHz band frequencies. It is designed as battery-operated, and yet still lightweight and comes with the included small lapel microphone to give more convenience and portable use. The PST-170 is equipped with two input jacks. The Auxiliary input is designed for allowing the use of audio devices just like the teacher's aid or tape players. The another jack is normally used with a microphone and it can be found on the top panel. The PST-170 is also compatible with the E.D.R. feature of the SR-400.

SR 50 Single Channel Receiver
The SR-50 Single Channel Receiver is capable of providing clear receptions and a fixed channel's simplicity. The economical receiver is operating on one of 17 fixed narrow-band frequencies in the 72-76 MHz band. Ergonomic raised volume control knob is designed to make the level adjustments easier and can be accessed by feel. Recessed headphone jack provides extra protection for earphone connections. Two AA batteries give up to 30 hours continuous battery life.

OPERATING FEATURES

Volume OFF/ON Control
This thumbwheel control is designed to serve as both an off/on switch and as a volume control. The Receiver is turned off when the control is in the extreme counterclockwise position, when viewed from the rear and the volume is loudest when the control is in the extreme clockwise position as indicated on the volume control.

Headphone Jack
The headphone jack is able to accept a 0.140-inch (3.5 mm) diameter miniature mono or stereo phone plug. A variety of accessory units are able to be plugged into this jack for reception of the desired channel(s) being transmitted.

Belt Clip
The belt clip supplied can be detached by spreading the wire apart at the tops and removing one side of the clip from the case and then the other.

HM2 Head worn Microphone
The Electro-Voice HM2 head worn microphone is the ideal microphone for anyone who is requiring high-quality vocals in a hands-free application. The HM2 is perfect for use by lead vocalists, singing instrumentalists, dancers, aerobic instructors and other presenters. The HM2 has a miniature electret condenser element designed with a cardioid polar pattern, which attenuates background noises such as sound from nearby floor monitors, on-stage musical instruments and crowd noise.
