Names of Things and What They Do
22.
Digital output jacks
Use these jacks to output digital audio to a digital audio device such as a CD/MD/DAT.
23.
Digital input jacks
Use these jacks to input digital audio from a digital audio device such as a CD/MD/DAT or from
a MIDI sound module that has a digital output jack.
* If you have connected a digital device to the optical (OPTICAL) connector, the optical connector will take
priority; the signals from the coaxial jacks will not be input.
24.
Input jacks 1, 2 (INPUT 1/L, 2/R)
These are analog audio input jacks. You can connect either XLR type or phone type plugs. Balanced
and unbalanced connections are supported for either type. 48 V phantom power can be supplied
to XLR type connections, allowing you to use phantom-powered condenser mics. In this case, turn
the phantom power switch ON.
The XLR type and phone type jacks have different input sensitivity, as shown below.
XLR type .......-50– -10 dBu Phone type .........-35– +4 dBu
If you are connecting a device with a low output level, such as a mic, we recommend that you use
the XLR type input jack.
25.
Input impedance select switch (INPUT 1 IMP)
You can select either high impedance (Hi-Z) or low impedance (Lo-Z) for the device connected to
input jack 1. If you connect a guitar to input jack 1, set this to high impedance (Hi-Z).
You must use the appropriate type of cable for the digital output jack or digital input jack you are
using.
COAXIAL ............ Coaxial cable
OPTICAL ............ Optical cable
* The UR-80’s digital input/output format complies with the S/P DIF standard.
fig.XLRTRS
* The UR-80 provides balanced (XLR/TRS) type input jacks, which are wired as shown in the diagram. Please
make sure that the device you are connecting is wired appropriately.
* The phantom power must be turned off unless you have connected a condenser mic that requires phantom
power. Malfunctions can occur if you supply phantom power to a dynamic mic or audio playback device. For
details on the specifications of your mic, refer to its owner’s manual. (The UR-80’s phantom power supply
provides a maximum of 10 mA at DC 48 V.)
* Do not connect different types of mic simultaneously; for example, do not connect a phantom-powered
condenser mic to input jack 1 and a dynamic mic to input jack 2. Supplying phantom power to a dynamic
mic or audio playback device will cause malfunctions.
