Disposal - Violectric HPA V181 User Manual

Towards the low end, your HPA V181's frequency response is not
restricted at all. This means that even extremely low frequencies - right
down to DC - will be amplified. "DC-coupling" as this technique is called,
is not necessarily useful since neither DC nor very low frequencies are
audible, but may damage your headphones on the other hand.
Therefore, the HPA V181 offers a low-frequency limiting option as well.
For this purpose, the two "LO-CUT" jumpers to the left and right of the
"VOLUME" control can be swapped from "DC" to "AC" position. When
set to "AC", low frequency response is limited to 12Hz, again referred to
the "3-dB point".
See also: technical appendix, page 28.
Ex-works, the HPA V181 is set to "AC" response (12Hz).
