3-4b) CONSOLE BALANCED OUTPUT TO UNBALANCED INPUT
This diagram illustrates an active balanced console output to an unbalanced equipment
input. Note that the (-) console output is left
unconnected. If the (-) console output is
grounded as you would with a transformer balanced output, then the console‘s output
driver
amplifier would beshorted and eventually fail.

3-4a) CONSOLE BALANCED OUTPUT TO ACTIVE BALANCED INPUT
The console outputs are low impedance (>100 ohms balanced) and can therefore directly drive
multiple high impedance inputs
(>10k ohm) without a distribution amplifier. These
active balanced
(transformerless) outputs do NOT require a terminating resistor
as a transformer balanced
output would.
