    INTRODUCTION plus AUDIO PROCESSOR The EQplus is the next generation of audio processing equipment from W2IHY Technologies. The EQplus was designed to be directly attached to the world famous W2IHY 8 Band EQ. The EQplus provides features such as Audio Compression, Downward Expansion, Effects and connectivity to 3 radios.

    FRONT PANEL CONTROLS This section describes each of the controls on the front panel. You should read through this section now. Some of the descriptions will be more meaningful after you first work through the Getting Started Tutorial. (1) Power On/Off Switch (S1) This switch turns the unit's power on and off.

    FRONT PANEL CONTROLS (4) Audio Input Impedance Switch (S5) This 3 position toggle switch is used to change the input impedance of the Mic and Aux Inputs (19,20 & 21). Input Impedances of 200 ohms, 600 ohms and 50K ohms ( HI-Z)may be selected. (5) Mic In Gain (R12) This potentiometer, when turned clockwise, can increase the Audio Input signal levels up to about +40dBv.

    FRONT PANEL CONTROLS (7) Equalizer On/Off Switch (S3) This switch turns the Equalizer on and off. When the equalizer is off, adjusting the bass and treble controls have no effect on the output audio. (8) Equalizer Bass (R37) This rotary potentiometer works only when the Equalizer Switch (7) is on.

    FRONT PANEL CONTROLS Incoming signals will have up to 20dB of compression introduced. The EQplus compressor circuitry contains a limiter that is preset at the factory. The limiter is set to limit the processed signals to 375 millivolts (-9 dB). When this level is reached the 1-st yellow LED on the bar graph will be on and the top Red (Limiting) LED will turn on.

    FRONT PANEL CONTROLS (14) EFFECTS PROCESSOR DELAY Potentiometer (R42) This potentiometer works only if the Effects Processor 3 position toggle switch is selecting either effect 1 or effect 2. The Delay control, when rotated clockwise increases, by up to about 80 milliseconds, the time that audio waveform is delayed.

    REAR PANEL CONTROLS (18) MIC SELECT This three position switch selects the YAESU, KENWOOD or ICOM microphone plugged into the 8 pin Mic Input (19). (Other microphones supported with mic adapters) (19) MIC INPUT This Input uses an 8 Pin microphone male connector. The impedance of this input is set by the Audio Input 3 position toggle switch (4).

  • Page 11: Rear Panel Controls

    REAR PANEL CONTROLS (20) MIC INPUT This RCA female connector is used as a microphone input. This connector works independent of the Mic Select switch (18) and may be used for another audio input source such as a microphone. The impedance of this input is set by the Audio Input 3 position toggle switch (4).

    Connect a mic into the EQplus 8 pin MIC IN Connector (19). Turn the rear mounted Mic Select switch (18) to the correct manufacturer the mic is wired for (Yaesu/Kenwood/ICOM). While talking into your mic, adjust the Audio Input Gain (5) so that 2 or 3 Green LED’s on the bar graph light up.

    GETTING STARTED TUTORIAL Audio Input Gain (5) so that 2 or 3 Green Bar Graph LED’s light up. This may require adjusting both the Mic Gain control on the 8 Band EQ and the Audio Gain control on the EQplus.

    GETTING STARTED TUTORIAL - Turn the Compressor control (11) fully counter clockwise. This setting passes uncompressed audio thru the compressor. Turning the compressor control clockwise increase the amount of compression. Set the compression to the desired level. You can turn the compression levels up to a point where talking into the mic causes the RED Limiting LED to come on .

    GETTING STARTED TUTORIAL The Level control (15) sets the amplitude that the audio delayed by the Effects Processor combines with the non delayed audio. Through experimentation, the user can find what Effects Processor Delay and Level settings are best for their voice characteristics.
