The Azden 330LT UHF dual wireless lavalier system is a powerful dual-channel UHF wireless microphone system for camera-mount applications. The system consists of 2 Azden 35BT body-pack transmitters, 2 EX-503L lavalier microphones, and the 330UPR portable dual-channel receiver. The inclusion of 2 body-packs allows users to operate both microphones simultaneously.With a feature set that includes 188 user selectable UHF frequencies, pivoting high-gain diversity antennas, and LCD digital display, the 330LT is guaranteed to meet the demands of consumer and professional video applications alike. The 330UPR receiver features main and headphone monitor outputs, and a removable shoe-mount adapter. Both the transmitter and receiver operate on standard AA alkaline batteries (not included).Azdens wireless microphone systems are designed for use with cameras, but the output of the wireless receiver is microphone level and can be plugged into any input intended for a microphone. However, in the case of hooking up to a PA system, youll likely have to convert the output connection from the mini-plug jack to either an XLR or TS or TRS connection.The Azden 330 wireless systems come with either an MX-1 or MX-2 cable, which maybe used to plug the receiver into a microphone level XLR input on a mixer or powered speaker. It is compatible with a mobile device by using the HX-Mi TRRS Mic/Headphone Cable.Features:- 188 Selectable UHF Frequencies- Dual-channel wireless lavalier microphone system- ne.w, Pivoting diversity High-Gain Antenna- Digital LCD Display w/ Multi-function Readout- Mini-Jack Out w/ Supplied 24 Mini-to-XLR Cable- Headphone Output on Receiver- Attached/Removable Shoe-Mount- Powered by 2 AA batteries330UPR Receiver:- Frequency Range: UHF 188 Frequencies (566.125-589.875MHz)- Type of Reception: FM- Oscillator: PLL Synthesized- RF Squelch Level: -95dBm- Frequency Response: 50Hz 15kHz- S/N Ratio: >84dB (100% Deviation)- au.dio Out: MIC Level Unbalanced 3.5mm Mini-Jack, -28 dBm (100% Deviation Mic Level)- Batteries: 2 AA Alkaline (2 x 1.5V) 5-6 hours runtime, 2 AA rechargeable Ni-MH (2 x 1.2V)- Dimension: 2.87W x 4.45H x 1.59D (73 x 113 x 40.5 mm)- Weight Approx: 10.2 oz (290g) w/ batteries35BT Transmitter- Freq.
