speaking, this is the voltage needed on the input of the amplifier in order to drive it to full output.

6. DISTORTION LIMITING ON/OFF - When turned on, this control enables the THD, circuit. When
switched ON the circuit greatly reduces all distortion products at high levels but is electrically
transparent at all other listening levels. In the OFF (bypass) mode, the distortion limiting feature
is disabled so typically unwanted clipping harmonics pass on to the speakers.

10. EXTERNAL CENTER CHANNEL INPUT - If a dedicated center channel signal is desired, it will be
sent in over this RCA jack. The INTIEXT switch must be in the EXT position for this to work.
11. INTERNAL/EXTERNAL SUBWOOFER INPUT - The subwoofer signal will be derived from the four
RCA inputs unless this switch is in the EXT position where it must have external signal inputs to
operate.
