MONITOR L/R outputs
13
These 1/4" TRS connectors provide a balanced stereo line-level output of
the monitor mix. These outputs can be used to connect to a pair of active
speakers, or to an amplifi er connected to passive speakers. The signal
level is controlled by the front panel MONITOR knob, and it can be se-
lected in software to be stereo or mono (see page 45).
Note: To connect a set of powered computer speakers, you may
need a common adaptor with two 1/4" TS plugs at one end and a
1/8" stereo jack on the other. See your local electronics store.
INPUT 1 and 2
14
Each "combo" input connector accepts either an XLR, a 1/4" TS or TRS
plug. Use these inputs to connect microphones, guitars, other instru-
ments, or line-level signals from mixers or preamps.
• For a microphone, you must use a standard microphone cable with an
XLR connector. Phantom power is available only on the XLR input, if
your microphones need it.
• For a guitar, typically you would use a 1/4" TS connector found on
most guitar cords. (TS=Tip-Sleeve). Push in the INSTRUMENT button
on the front panel.
• For a line-level input such as a keyboard, external mixer, or preamp,
use a 1/4" TRS connector (TRS=Tip-Ring-Sleeve), or 1/4" TS . Leave
the INSTRUMENT button out.
Note: The XD-2 has an input-level auto-detection feature which
sets the input level according to the type of connector you plug
in. You still need to adjust the GAIN knobs correctly (see page 26).
