Conguration and setup
1: Standard amplier operation
The MiniAMP can be used as a standard amplier
by simply connecting the audio source to the
inputs, the speakers to the outputs, the power
supply to the power in port, and conguring the
volume and tone controls for the desired sound.
2: Intelligent volume control
The MiniAMP can be used with a control system
to allow intelligent volume management. The
contacts on the 5-pin phoenix block can be
used to attenuate the right and left channels
independently by shorting the corresponding
pin to ground. The amount of attenuation is
determined by an internal potentiometer which
can be accessed by inserting a small screwdriver
through the orice on the front panel of the
MiniAMP. The shaft of the screwdriver should be at
least 25mm long, and excessive force should not
be used.
NB: It is not necessary to remove the casing to
access the attenuation potentiometers. Any
damage caused by unauthorised opening of the
casing is not covered by the standard RSF 3 year
warranty.
3: Bridge mode
As a digital amplier there are no switches or
jumpers to adjust in order to run the MiniAMP
in bridge mode. Simply connect a mono audio
source to both the left and right channels, and
connect the loudspeaker to both outputs in
parallel.
NB: Minimum loudspeaker impedance in bridge
mode is 8 ohms.
4: Muting
By connecting the mute pin on the phoenix block
to ground it is possible to mute the output of the
MiniAMP. Because the MiniAMP is a digital
amplier this reduces the current drawn to
negligible levels. A low consumption version of
the MiniAMP can be produced on request for
situations where the MiniAMP is to be running on
batteries or a non-guaranteed power source (eg
solar cells). Please contact us for details.
5: Indication LEDs
There are three LEDs on the MiniAMP. The blue LED
on the front panel indicates the presence of the
power supply. The orange LED on the front panel
indicates signal presence / level on one or both of
the audio channels. The red LED on the rear side
of the MiniAMP indicates an internal error. If this
persistently lights up after resetting the MiniAMP
then please contact your authorised RSF dealer.
6: Protection functionality
The MiniAMP has inbuilt protection to avoid
inadvertent damage to either the speakers, or to
the MiniAMP itself. If the input level is driven too
high on either or both channels the output on
both channels will be cut until the input level is
reduced, or the volume control knob on the front
panel is turned down. If the impedance at the
output of either channel becomes too low the
output to both channels will similarly be cut. In this
case check the cabling and if necessary test with
another loudspeaker.
The MiniAMP is a highly efcient class T digital
amplier and should not produce large amounts
of heat, however should the surrounding
environment become too hot the MiniAMP will
shut down the output to avoid circuit damage.
