The EQplus is designed to be directly attached to either your microphone (Icom, Yaesu or Kenwood) or to the W2IHY’s 8-band EQ (W2EDGE), or to your Kenwood, Icom, or Yaesu HF transceiver. The EQplus provides Audio Compression, Downward Expansion, Effects and connectivity to three radios. There is a choice of three different mic impedances, 200, 600, and 50k Ohms, and there is a 5V supply for mics that require this such as Icom HM-12, HM-36, and SM-6 and Heil HMI and ICM which can be plugged in direct to the unit.

Features include a LED bar graph that indicates pk-to-pk audio levels, an equalizer with separate Bass and Treble controls, and a Compressor /Downward Expander. There are two effects in the Effects Processor, Effect 1 emulates dampening sound-reflecting multiple time from a surface, and Effect 2 emulates sound-reflecting once from a surface plus there is a delay control which controls the speed delay up to 80 milliseconds
