The Azden 325-Series Dual-Channel Wireless Microphone System is a portable, wireless microphone system designed for camera mount applications. At the heart of the system is the camera-mountable 325UPR dual-channel receiver, capable of receiving signals from two transmitters simultaneously. The systems are packaged with two transmitters and this system features the 325UPR, 35HT handheld transmitter, 35BT beltpack transmitter and lavalier microphone.
The 325UPR receiver is capable of dual-channel operation over the 566.125 - 589.876MHz UHF band. There are 188 user selectable frequencies to choose from and a digital LCD display provides access to all the receivers functions. A removable shoe-mount enables easy mounting onto video cameras. Two 1/8" mini output connectors provide a main output and headphone monitoring output. The 325UPR is powered with two AA alkaline batteries.
The 35BT beltpack transmitter includes the EX-503 lavalier microphone, and the 35HT handheld transmitter features a dynamic microphone head. The combination of handheld and beltpack provide the ability to conduct interviews, deliver presentations, capture audio from talent, etc. Just like the receiver, both transmitters feature 188 selectable UHF frequencies, feature LCD displays and operate on two AA alkaline batteries.
The Azden 325-series is an ideal cost-effective camera mountable wireless package that features the flexibility of dual-channel operation.

Comments about Azden 325ULH Dual-Channel Portable Wireless Microphone System:
The receiver is camera shoe mountable (as opposed to mounting under the camera on a tripod head).
Setting and identifying the active receiver/transmitter channel is clearer (less cryptic) than on some other brands.
The system also works well in a house environment; I plugged the receiver's mic output into a mixer board and it worked as clearly as any of the other (non-camera) wireless systems we have.
Having many different channels available lets one find an interference-free channel. Likewise with inter-modulation interference with other wireless systems. At first I encountered a few that were noisy, but I experimented with different channels until a free one was found.
Overall it is a very fine system.
