switch power off at all
connected units.
The T

ESIGNER
is fitted with XLR-connectors for balanced
operation and 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 rejec-
tion); -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:
