WMT1A
The WMT1A is a general-purpose matching transformer that allows proper
connections between high (10k-ohm) and low (600-ohm) inputs and outputs.
The WMT1A can be used to balance an unbalanced line or provide isolation
between two pieces of equipment. The WMT1A can be configured to produce
a balanced, microphone level signal from a line-level signal such as that from
a pre-amp or music source.
Connecting Amps to Other Equipment
When connecting amplifiers to other equip-
ment, the WMT1A is a “must have” because it
can solve a variety of problems.
• Where signal levels are insufficient to
drive an amplifier's AUX input to full
volume, installing the WMT1A on the
input will increase the voltage to the input
by about 5 times, providing plenty of level.
• Where input ground loops are causing a
hum problem, the WMT1A's isolation
transformer can break the loop and
eliminate the hum.
• When unbalanced signals need to be sent
over long distances, the WMT1A can
balance them at both the send and receive
sides and reduce the possibility of noise
pickup.
• The WMT1A allows a microphone input
to be used for an AUX signal input.
By moving a jumper on the WMT1A, the
attenuation of the unit is changed on the
high-impedance side to be 100 times less
than the signal level on the 600-ohm side.
A MIC input should work well with the
signal at this reduced level. A female XLR
to RCA adapter can then be used to make
the connections.
