10 HIGH PASS FILTER
With this filter, any frequency below 30Hz or 50 Hz
is left out, not reproduced by the amplifier. This
way, speakers less efficient and effective in repro-
ducing low frequencies can be protected. This also
allows such speakers to perform better.
11 LIMITER ON/OFF
This switch turns on or off the built-in limiter. When
the input signal level becomes too high, causing
amplifier to loss definition and to distort. Limiter
helps prevent signal from losing definition and be-
coming distorted by automatically decrease signal
level for guaranting maximum dynamic range.
12 GROUNDING – FLOATING SWITCH
This switch allows user to choose between circuit
or chassis grounding for resolving any grounding
conflict. Under normal use and for safty, such
switch should be in the “grounding on” position.
When grounding loop and hum occur, try switching
to “floating.” When the hum is gone, it means the
common ground is on the other equipment.
13 CHASSIS GROUNDING CONNECTING POINT
To avoid the possibility of ground loop, this unit
comes with chassis grounding point allowing it to
be connected to other units for sharing a common
grounding.
14 POWER CORD
This cord draws electricity from power outlet. Near
by it, there is an indicator that tells you what volt-
age your unit operates in. Check the AC voltage
before connecting the power plug to the outlet.
Make sure the AC requirement shares the same
voltage used in your country (For example, while
some coutries use 100V and 120V, others use 230V
and 240V).
