Fan Inlet Grills and Filter
- UA Series amplifiers are cooled by two rear-
mounted fans. Cool air from front grills is filtered and flows over the heat
sinks and exhausts to back side. Make sure these outlets remain clear to
allow unrestricted air flow.
3. AC Power Switch
- UA Series amplifiers have a front-panel AC mains
power switch.
4. Power Indicator -
This LED will glow when mains power is applied to the
unit. This light may continue to glow briefly after mains power has been
turned off, this is normal.
5. Channel 1-3 Clip Indicator (for UA-4000: Channel 1-4 Clip Indicator)
-
This LED will begin to flash when the channel begins to overload (clip),
at this point the channel will begin to distort. Under heavy clipping
activity, lower the channel's gain control to reduce the risk of damage to
your speakers and amplifier. This LED may glow when the unit has been
turned off, this is normal.
6. Channel 1-3 Signal Indicator (for UA-4000: Channel 1-4 Signal Indicator)
-
Illuminates to indicate that a signal (above a minimum threshold) is present at
the amplifier input, and that the signal is being amplified.
7. Channel 1-3 Gain Control (for UA-4000: Channel 1-4 Gain Control) -
This rotary knob is used to control the output signal level of the channel.
Turning the knob in a clockwise direction will increase output signal
level.
