Makes it easier to control the audio input on your bhi ParaPro EQ20 audio DSP unit
The bhi ATT2 high level to low level audio converter is used to convert high level audio signals to low level audio. The ATT2 attenuator pad was designed for use with amateur radio transceivers and receivers mainly for use with the bhi ParaPro EQ20 range of audio DSP units, but can also be used with other audio equipment provided the parameters of the audio equipment being connected are within the specification of the ATT2.
The ATT2 is a passive device which effectively enables a wider range of AF/volume adjustment to be used on the radio equipment before the overload LED on the bhi ParPro EQ20 unit comes on, making it less sensitive and easier to use. The ATT2 accepts mono or stereo speaker level signals and will accept input levels up to 1 Watt (2.828 Volts p-p into an 8 Ohm Speaker) and will attenuate the audio down to line level at around 1 Volt (line level at 10k Ohm).
The ATT2 unit simply fits between the extension speaker socket of your radio (high level audio source) and your bhi ParaPro EQ20/EQ20-DSP unit or audio equipment. Connect from the extension speaker socket of your radio or audio source to the input socket on the ATT2 unit using a 3.5mm mono or stereo jack plug lead. Connect the output lead of the ATT2 unit to you bhi ParaPro EQ20/EQ20-DSP unit or audio equipment. Note: Use the audio isolated LLC1 if you encounter any stray RF or earth loop issues.
