High pass filter toggle switch — Use a small screwdriver to toggle this recessed
two-position toggle switch that alternates between Off (no filtering) and 80 Hz. The
XPA 2002-70V and XPA 2002-100V have 2 switches, one for each output channel.
The XPA 2003C-70V and XPA 2003C-100V have one switch for the line distribution
output channel (channel 3). Setting the switch to 80 Hz prevents the saturation of
the speaker input transformers by low frequency signals. Saturation may result in
undesired overheating of the speaker transformers.
