COMBINATION OF W2IHY 8-BAND EQ AND EQplus
WV4R Puts Loud, Clean Audio In Your Face
With its wide range of adjustability, the W2IHY 8-Band/EQplus combination delivers the transmit audio characteristics you want to achieve. This highly articulate, crystal-clear signal is from Murf, WV4R using a $10 microphone.
EQplus 101. Required Listening
In this example, WV4R turns off the W2IHY audio processing stages and turns them back on. Listen to the fascinating procedure and the stunning results.
EQplus Creater, Julius Jones, Demonstrates His New Product
Listen to EQplus designer, W2IHY in QSO on 20 meters. Julius is transmitting on an ICOM 756 PRO II with a Heil Goldline Pro microphone. Notice the dramatic improvement in signal to noise (talk power) when the EQplus compressor is activated. Our thanks to N4FZ for making this recording.
Are You A Believer? W6OBB is
This high-quality signal from W6OBB is pleasing and robust. Art’s audio is a listening treat for everyone on the receiving end. His Yaesu MD-200 microphone drives W2IHY processing gear which drives an ICOM 7800. Recording courtesy of NU9N.
Sig From Little Rig
We couldn’t believe our ears when K4APO sent this recording. Walter’s audio is a thrilling example of what is possible when using W2IHY audio processing on a radio with relatively narrow transmit bandwidth. The microphone is a Heil Goldline Pro and the rig is an ICOM 706 MKIIG. We’ve never heard a 706 sound this good …and … this BIG!
It’s Off. It’s On. It’s Powerful!
This recording of W8MW demonstrates the night and day difference between unprocessed microphone audio and audio that’s enhanced by W2IHY processing. Mike is using an ICOM 756 PRO with an inexpensive Radio Shack dynamic microphone.

W2IHY EQUALIZER DEMONSTRATIONS
EQ Makes A Poor Microphone Sound Very Good
This microphone had very little low frequency output. Listen to the dramatic improvement made by boosting the W2IHY Equalizer at 50, 100, 200 & 400 Hz.
EQ Set For DX & Contest Audio
Examine how the audio becomes more piercing and penetrating when equalization is set for substantial high-frequency content. Simply adjust the W2IHY Equalizer for more energy at 1600 and 2400 Hz. This enhances articulation and boosts apparent loudness.
EQ Works Miracle On Another Poor Microphone
Hear a thin, tinny-sounding microphone become more full and pleasing to the ear. In this example, the microphone needed boosts in the low and mid-range frequencies.

W2IHY NOISE GATE DEMONSTRATIONS
Noise Gate Reduces Background Noises In The Shack
QRM inside the shack? Here’s how to cut it down to size. Listen to the background voices go away in this noisy shack. The W2IHY Noise Gate works wonders on all sorts of noises including linear amplifiers, air conditioners, fans, etc.
Noise Gate Goes Mobile. Stunning Reduction Of Wind & Traffic Noise
We went mobile with a W2IHY EQ/Noise Gate so you could hear its performance in a truly worst-case noise environment. The wind and traffic were nearly as loud as the voice. Judge the results. Then imagine what our Noise Gate can do for you!
