Before connecting the T

ESIGNER
switch power off at all
connected units.
The T
RANSIENT

ESIGNER
is fitted with XLR-connectors for balanced
operation. The following illustration shows the pin-wiring:
To ensure optimal signal quality, SPL has developed a new hybrid-
component balanced input/output stage using all laser-trimmed
resistors with a tolerance of 0.01%. This approach has resulted in
an exceptionally high CCMR (common mode rejection); -80 dB at
1kHz and -75 dB at 10 kHz.
Should the need arise to use the XLR connectors in an unba-
lanced system, pin 3 of the XLRs should be grounded. The follo-
wing illustration shows how to properly unbalance a balanced
signal:
