COMPRESSOR GAIN

The MOD 232’s Compressor Gain is set in “Moderate” mode from the factory. Use this setting for

simultaneous interpretation. Be sure that the compress pot control, located on the front of the

MOD 232 (Figure 6, page 7), is turned fully counter-clockwise. Compression can be added if

desired by turning the compress pot control clockwise.

For hearing assistance applications, the MOD 232’s Compressor Gain can be set to “Maximum”

mode. For additional compression, use a tuning wand (PLT 005) or small screw driver and gently

turn the compress pot (Figure 6, page 7) on the front of the MOD 232 clockwise.
