Combo input jacks 1–4
These are analog audio input jacks with high-quality
preamps. Either XLR type or phone type jacks can be
connected here, as appropriate for the equipment you are
using. Balanced or unbalanced connections are supported.
The XLR type jacks provide 48 V phantom power, allowing
you to connect phantom-powered condenser mics. In this
case, turn on the phantom power switch.

fig.jack-type
* You must turn phantom power off (button in the outward position) unless a condenser
microphone requiring a phantom power supply is connected to the XLR type jacks.
Malfunctions will occur if you supply phantom power to a dynamic microphone or to an
audio playback device. For details on the specifications of your microphone, refer to the
owner’s manual for your microphone.
(The UA-1000 supplies phantom power at DC 48 V, maximum 10 mA x 2 systems)
