CONNECTIONS
Headphones Output
You can connect your headphones to the Desktop Headphone Amplifier using either an
unbalanced 1/4" (6.35mm) TRS plug or a balanced 4-pin XLR connector.
If your headphones use a 3.5mm TRS plug, you will need a 3.5mm-to-1/4" adapter,
such as the Monoprice 7139 adapter (available separately).
You cannot use both the balanced XLR and unbalanced 1/4" TRS headphone outputs
at the same time. When a 1/4" plug is inserted, the XLR output is muted.
When plugging or unplugging a 1/4" connector, completely insert or remove the
connector in one quick, smooth motion. Because of the design of the plug, keeping
the connector plugged in half way can cause a short circuit between the left and
right output channels and may trigger the short circuit protection feature.
