5. Gain Control
Each channel has a 41-step Gain control with approximately 20dB of input head
-
room. The dB steps are maintained down to 14dB of atten uation.
Note: The headroom is the margin between the nominal level of a
signal and the maximum level that the amplifier is able to handle cor-
rectly before saturation occurs with consequent clipping.
6. Operative Mode Indicator
This is a bi-color LED that warns the user about the operating mode of the ampli
-
fier. If the LED is lit in orange it means the amplifier is in PARALLEL mode. When it
is lit with yellow, it indicates that the amplifier is in MONO-BRIDGE mode.
7. Power Switch
Press the switch to the (1) position to turn ON the amplifier and to the (0) position
to turn it OFF.
Note: When the power switch is turned OFF, the device is not com-
pletely disconnected from the mains. So if the amplifier is not used
for a long time, please disconnect the power cord from the outlet.
8. Front Panel Ventilation Grid
It allows constant ventilation between the front and back of the amplifier. This se
-
ries amplifiers pull air from the rear, and aspirates it from the front, thus allowing
the heat to dissipate without heating the rack. When the amp works harder, the
fan will speed up and expel more hot air. It is suggested not to obstruct this grill.
