CONNECTORS
For this equipment, the convention for balanced XLR connections pin 2 is 'hot' or '+' and
pin 3 'cold' or '-'. Some users and equipment implement the opposite. This should not be
problematic providing a consistent implementation is used throughout.
Note: When interfacing to other devices such as A/D and D/A converters it may be
necessary to check the manufacturers polarity convention if the correct absolute phase
is to be maintained. However, this does not affect use of the MEA-2 with either polarity
convention
.
Balanced analogue audio connections should use a good-quality screened twisted-pair
lead. Unbalanced connections must also be screened.

Input connections
The following diagrams illustrate correct connection for balanced and unbalanced sources:
Using the above method when driving the MEA-2 with unbalanced sources should provide
best results.
Note: The maximum input amplitude is reduced by approximately 6dB from the
n28dBu when driving the MEA-2 from an unbalanced source
