It effectively removes heterodynes, ignition noise, lightning crashes, power line noise. QSO's are more fun without all the background noise. The DSP recognizes the intermittent nature of CW and allows it to pass noise free. CLRstereo features independent "Left" and "Right" channels, each with DSP filter level, Tone and Volume (audio level) controls and a red "CLIP" LED to indicate when that channel input level is too high. Next to the front panel toggle Power switch is a green LED to indicate powered condition. CLRstereo can process two channels simultaneously, for use with two separate radios or with a radio that features two separate receivers, such as Main and SUB. Please note that the CLRstereo does not contain a power amplifier. While the output is sufficient for a headphone or low level speakers, the CLRstereo is intended to be connected to an amplified speaker system. Specification of the CLRstereo ClearSpeech® Dual Noise Reduction Digital Signal Processor: - Enclosure: Metal, powder coat painted - Dimensions (WHD): 7.25 x 1.5 x 3.5 in. - Input: 1/8 in. (3.5 mm) stereo female (TRS) - Output: 1/8 in.

INRAD DMS-1 PTT Desk Stands
INRAD DMS-1 PTT Desk Stands are attractive desk microphone accessories, with a lockable Push-To-Talk switch. They are ready for your INRAD microphone, or other standard stage microphone, with a 1 in. body. The DMS-1 base is metal, painted dark grey, which weighs a hefty 2.5 lbs. to keep it from sliding around or being knocked over easily. Total weight of desk stand and microphone is over 4 lbs.! The included rubberized microphone clip easily grips the microphone body, and mounts with locking star nut onto the 3.125 in. tall, standard 5/8 in.-27 threaded metal chrome stand pipe. A circular rubber ring in the threaded base for the standpipe and mic clip provides an integral shock mount for noise isolation. A large push-to-talk bar switch is on the front of the desk stand base. Lock the PTT for long transmissions by moving the top-side silver slider switch to the left while the PTT switch is down. To release, slide the switch back to the right. Optional INRAD microphones come with a pro-style 3-pin XLR connector and 7 ft. 9 in. adapter cable with 1/8 in. plug (3.5mm male). Included with the DMS-1 is a handy 9 in. version of that mic cable, for a better looking desk mic setup. The back of the DMS-1 base has a 1/8 in. jack (3.5mm female) for the audio from the microphone and a 4-pin XLR male output to deliver the audio and PTT from the DMS-1 PTT Desk Stand to the transceiver. Selected by transceiver, choose one required INRAD coiled cord adapter cable (DM Series) terminated with 4-pin XLR female and a specific transceiver microphone female connector: * INR-DM-I --Adapter Cable for INRAD DMS-1, 4-pin XLR to Icom 8-pin round Mic Input * INR-DM-K --Adapter Cable for INRAD DMS-1, 4-pin XLR to Kenwood 8-pin round Mic Input * INR-DM-Y – Adapter Cable for INRAD DMS-1, 4-pin XLR to Yaesu 8-pin round Mic Input * INR-DM-YM -- Adapter Cable for INRAD DMS-1, 4-pin XLR to Yaesu 8-pin modular Mic Input Own multiple transceiver models with different mic jack configurations?

The M-Series microphones are interchangeable. To change from one mic to another, unplug the 3-pin XLR cable from the back of the mic and pull it off the clip.
