The PDWM-2115 VHF Wireless Microphone System from Pyle Pro is a 2-channel system which features a VHF narrow-band receiver with a dual-frequency design allowing the use of two microphones at the same time. The system includes three mics: a handheld transmitter for one channel and a beltpack transmitter with a choice of a lavalier microphone or a headset microphone for the other channel. The level of each microphone is controlled by separate volume control potentiometers on the receiver.
