Grounding terminal

927

Depending on the circumstances of a particular setup, you may experience a

discomforting sensation, or perceive that the surface feels gritty to the touch when

you touch this device, microphones connected to it, or the metal portions of other

objects, such as guitars. This is due to an infinitesimal electrical charge, which is

absolutely harmless. However, if you are concerned about this, connect the ground

terminal (see figure) with an external ground. When the unit is grounded, a slight

hum may occur, depending on the particulars of your installation. If you are unsure

of the connection method, contact the nearest Roland Service Center, or an

authorized Roland distributor, as listed on the “Information” page.

Unsuitable places for connection

• Water pipes (may result in shock or electrocution)

• Gas pipes (may result in fire or explosion)

• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)

AC adaptor jack

Connect the included AC adaptor to this jack.

* Do not use anything other than the included AC adaptor; doing so will cause

malfunctions.

20.

Phantom power switch

This is an on/off switch for the phantom power supplied to the XLR connectors of

the

combo input jacks (1)

on the front panel.

* You must leave this switch in the Off setting (toward the right) unless condenser

mics requiring a phantom power supply are connected to the XLR type jacks.

Malfunctions will occur if phantom power is supplied to dynamic mics or audio

playback devices. For details on the requirements of your mic, refer to the owner’s

manual for the mic you

’

re using.

(The UA-101’s phantom power supply is DC 48V, maximum of 20 mA.)
