ACT 545 Quad-Channel 1U True Diversity Wireless Microphone System

Features:

EIA standard metal chassis, a newly designed LCD, rotary control knob and buttons on the control panel with similar operation and display modes of ACT-800 Digital Series.
LCD screen automatically shifts colors to identify “Working” and “Standby” mode.
Most reliable 24 MHz narrowband true diversity receiving circuit equivalent to ACT-7 Series.
Long-distance and stable reception without signal dropout, greatly decreases intermodulation distortion and increases interference-free compatible channels.
Industry’s first “PiloTone & NoiseLock” circuits and the RF interference warning indicator for proper adjustments of the SQ level to avoid interference.
MIPRO Auto Scan and ACT™ function provides the transmitter’s frequency with precise and rapid sync to the receiver.
7 preset groups with a total of 80 pre-saved frequencies.
User-defined group allows users to choose and save up to 16 channels from 961 available frequencies.
Output level is pre-adjusted to equal the microphone capsule’s sensitivity.
Switchable output levels for best sound quality options, free from distortion.
