Using Your Uam4 - Ramsey Electronics UAM4 Manual

USING YOUR UAM4 AMPLIFIER
Now that you have your UAM4 assembled all you need to do is follow the
steps below and you will be enjoying 40 watts of audio power.
Required items
•
A Power supply able to provide between 10 and 18 volts DC at least 2.6
amps - A lower current rating will work but you will not be able to achieve
the 40 watts of power output at 18 volts. We recommend the SPS183
power supply, available from Ramsey.
•
An audio source - This may be either a balanced signal or a single ended
unbalanced signal such as provided by the record, or line level output
provided by many audio system components.
•
Two speakers for stereo operation – (Obviously for mono operation you
only need one speaker...) Make sure they have enough power handling
capability for the UAM4!
•
Although not absolutely required, you may want a case or mount to hold
your UAMA4.
Connecting Your UAM4
In order to connect your UAM4 you need to first decide a few things about the
type of equipment you are going to use it with and how you want to use it. To
do this we'll ask you a few questions. Based on your answers, we can point
you to the set up instructions best suited to your needs. In all configurations
the connections to the UAM4 are made with Euro style screw terminals. You
will need to prepare appropriate connecting cables to match the output of your
equipment. Just read through and follow the instructions below to determine
the required connections.
INPUT SETUP
First we need to set up the UAM4 for either stereo or mono input. If you are
going to be using your UAM4 as a stereo, (two input signals) amplifier
continue reading the "STEREO INPUT" steps below. If you are going to use
the UAM4 as a mono (one input signal) amplifier, go to the "MONO INPUT"
section.
STEREO INPUT
Remove the jumper from jumper block H3 labeled 'JUMPER FOR
MONO' located above and between the input connectors, J1 and
J2, if it is installed.
Make sure there are no jumpers installed between the 'L+', 'R+' and
between the 'L-' and 'R-' jumper points just below the speaker
connection terminals.
Since you are using your amplifier in stereo mode you will be using
