Lectrosonics EQ1_EQ2 - Manual (Page 14)

Set Pop Suppress Setting - Allows the pop suppress setting to be adjusted. Range is from 0-80 plus 127. 0-80
corresponds to -40dBu to 0dBu threshold values in .5dB steps, and 127 is 100dB mute (Pop suppress off). Byte 1 is
the new setting. Byte 2 is 0 or 1, and indicates whether or not to save the new value to EEPROM.
Host sends command - 10
Host sends 2 bytes: Byte 1: Pop suppress setting (see above) Byte 2: 1 - Save to EEPROM, 0 - don’t
Host receives 1 byte: 100 to confirm save.
Bandpass Filter/Log Converter Commands
Output BP Filter Center Frequency - Outputs the current center frequency of the 1/3 octave bandpass filter. The
first byte sent is the frequency, and the second byte is the range multiplier. The range of the frequency byte is from 1­
255. The values for the range multiplier are 1, 2, or 3. These values correspond to x1, x10, and x100.
Host sends command - 11
Host receives 2 bytes: Byte 1: Center frequency (1-255)
Byte 2: Range multiplier (1-x1, 2-x10, 3-x100)
Set BP Filter to 1/3 Octave Center Frequency - Allows the center frequency of the 1/3 octave bandpass filter to be
set to one of the 27 ISO center frequencies between 40Hz and 16KHz. Byte 1 is the 1/3 octave frequency (0-26, 0 ­
40Hz, 26 - 16KHz).
Host sends command - 13
Host sends 1 byte:
Byte 1: Center frequency (0-26)
Output BP Filter Log Converter Level - Outputs to dB level of the signal being measured by the 1/3 octave
bandpass filter. Note the only values from 20 to 120 (-60 to -10) are valid. If a 0 is returned, the level is below -60,
and if a 255 is returned, the level exceeds -10.
Host sends command - 14
Host receives 1 byte: 20-120, 0, or 255; BP filter level
Input/Output Switching Commands
Output Input Source - Outputs the current input source, EQ In or Ref Mic In for either the current setup or one of the
stored Target EQ curves.
Host sends command - 15
Host sends 1 byte:
Byte 1: 0 - Current input source
1 - User 1 source
2 - User 2 source
3 - User 3 source
4 - Factory 1 source
5 - Factory 2 source
6 - Factory 3 source
Host receives 1 byte: 0 - EQ In is source, 1 - Ref Mic In is source
