CONNECTING YOUR SPEAKERS
You're down to the last few connections and your UAM4 will be ready to go.
Your speakers are going to be connected to the speaker output terminals
J6, J7, J8, and J9. If you are using your UAM4 as a stereo amplifier keep
reading. If you are operating your UAM4 in mono mode, go to the "MONO
SPEAKER CONNECTION" section.
STEREO SPEAKER CONNECTION
If you are using your UAM4 as a stereo amplifier then you will connect the
left speaker to the 'LFT+', J6, and 'LFT-', J7 terminals and the right speaker
to the 'RT+', J8, and 'RT-', J9, terminals. It is important that the speakers be
connected to these terminals with the proper polarity. In other words look at
your speakers and you should see there is a red and black terminal on each
one. (It is possible that your speakers have some other polarity indication
on them but this is the most common. Consult the owner's manual if they
are different.) It is important that the two speakers be connected with the
same polarity, (red terminal to LFT+ or RT+ and Black terminals to LFT- and
RT- for example), to the UAM4. While it will not damage the speakers or
UAM4 if they are connected with different polarity, the sound will not be as
expected. Please refer to the "DETAILED INPUT/OUTPUT
INFORMATION" and "NEAT-TO-KNOW INFORMATION: Determining
Speaker Phase" sections of this manual for more detailed information.
That's it for the speaker connection. Now go to the "POWER SUPPLY
CONNECTION" section.
MONO SPEAKER CONNECTION
If you are using your UAM4 as a mono amplifier then your speakers will still
be connected to the speaker output terminals J6, J7, J8, and J9 but there
will only be one channel input, (which is applied to the right input terminals),
instead of the stereo left and right channels. Select the mono configuration
below that you set up in the previous sections and follow the instructions.
40 WATT MONO OPERATION SPEAKER CONNECTIONS
In the 40 watt mono configuration the output terminals are connected in
parallel. In other words the 'LFT+' and 'RT+' terminals are the same and
'LFT-' and RT-' terminals are the same. The speaker(S) may be
connected to these two sets of terminals. Please note that these
terminals are connected together on the UAM4 board.
Warning: DO NOT remove the jumpers between 'L+' and 'R+' and
between 'L-' and 'R-' jumper points and simply connect the output
terminals or speaker leads to together at any point off the board.
Doing so may cause undesired results, (distortion, feedback, etc.)
and damage to the UAM4.
