troublesome frequency range by enabling the LISTEN feature
to hear a set ess range. Then use the FREQ and WIDTH pots to
adjust the range. (See LISTEN in the Global Block description).

DSR-1. Typically use a pre- or post-insert, and set the
DSR-1’s input to an acceptable level. Notice the
relationship between your FREQ and WIDTH settings
and the ess meter level. The ess meter level is located
in the output meters block on the right side. Start by
pressing the LISTEN button to facilitate isolation of the
ess band. To start with, set the ratio to 1:1 so that no
compression is applied to the band. Now adjust the
