ATW-R2100a receiver and ATW-T220a handheld cardioid dynamic microphone/transmitter.
The ATW-T220 cardioid dynamic wireless handheld transmitter incorporates the PRO 41 dynamic element created for professional live sound venues. The element includes internal shock mounts for low handling noise. An integral two-stage pop filter within the steel headcase protects against “p” pops and other breath plosives. The transmitter includes an adjustable gain control to tailor the input to the sound source. An integrated two-position power/mute switch
eliminates the need for a separate mute button. An RF power select switch offers high and low settings. The transmitter operates on two standard AA batteries and a battery condition indicator illuminates when the batteries are good. An internal channel selector allows the transmitter to operate on any one of ten channels. The transmitter is constructed of high-impact materials and includes a heavy-duty microphone stand clamp.
The ATW-R2100a is a True Diversity UHF wireless receiver operating in the UHF bands of 656.125–678.500 or 487.125–506.500 MHz. The automatic frequency scanning eliminates the need for searching for clear channels and automatically selects the most appropriate frequency for the area in which the wireless is operating. A pre-coordinated integral channel plan allows for simultaneous operation of any of the ten channels in a given location. The flexibility in programming both the receiver and transmitters eliminates confusing frequency groups and other frequency coordination problems. A two-position switch turns on/off 12V AC antenna power for use with powered antennas or accessories. Advanced Tone Lock™ adjustable squelch system fights interference. High sensitivity dual IF design using true diversity operation with silent automatic switching provides dropout-free performance. Front panel LCD receiver display provides continuous indication of transmitter RF signal strength, selection of internal dual (True Diversity) receiving sections (A&B), along with the audio modulation level of the received signal. Both balanced XLR-type and unbalanced 1/4" output connections with output gain adjustments are located on the rear panel. The XLR-type output includes a ground lift switch to prevent ground loops. Features not often found in other receivers include metal receiver construction, detachable wave receiver antennas, AC or 12–18V DC operation, front panel power switch, and included rack mount kit.
