FREQ and WIDTH pots so you hear as much of the problematic sibilance as possible. At the same time, minimize the amount coming through of the signal you wish to leave unaffected. Typically, you will find a center frequency in the range of 3k to 6k, with a width ranging from 20 to 40 is useful. Watch the key level change as you adjust to the frequencies of the ess range. Now adjust the DSR-1’s threshold level using the threshold pot. The threshold level is also portrayed as the small horizontal bar between the S-BAND and GAIN meters. Watching this is a good way to meter where your threshold level should be after you have dialed in an ess range. The DSR-1 only affects a signal that is above the set threshold. Finally, adjust your RATIO pot to apply a desired amount of compression to your specified ess range. For example, 3:1 means that if a signal is 3 dB over the threshold, it will be reduced in amplitude to 1 dB over the set threshold. Now you’ve got a good starting point. Take it out of LISTEN mode and continue to tweak the parameters until you’ve got the sound you want!

Note: You may need to change threshold levels to compensate for adjustments made with the FREQ and WIDTH pots.
THRESH
THRESH (threshold range) ranges from –40 to 0 dB, and is adjusted using the THRESH knob. S-band signal above this threshold will get reduced in amplitude by an amount determined by the ratio. See “A Closer Look,” above for further information.
