YORKVILLE Bass Master xm200 Manuel De L'utilisateur page 4

The line-level signal at the Effects Send jack is post-fader and post-EQ (it is affected by the
Volume and all Tone controls). The Effects Send would normally be connected to the input of the
effects device with a shielded patch cord. When a plug is inserted in the Effects Return jack the
signal goes directly to the xm200's internal power amp. Technically, by inserting a ¼-inch plug into
the Effects Return, you are disconnecting the internal preamp signal going to the power amplifier
stage. The power amp can only receive signals routed through here (i.e. it isolates the power amp).
Use shielded patch cords for all inter-connections.
Tip: You can "slave" your xm200 to another amp. As an example, if you wanted to run two bass
amps for a large gig, you can simply run a shielded patch cable from the line output of the other amp
(possibly another xm200) to the Effects Return of your xm200.
XLR Line/DI Output
This is your interface to the P.A. or recording console. Using an XLR mic cable or a shielded
patch cord with a female XLR connector on one end (balanced or unbalanced, e.g. a high or low-
impedance mic cable), connect the Line/D.I. Output to the input of the mixer. Electronic balancing
circuitry minimizes the possibility of hum or noises when the Line/D.I. Output is connected to a
mixer, even when the mixer does not have balanced inputs. Also, this output can be made D.I. or
Line according to the selector button setting in the following section.
Line/D.I. Selector Button
The D.I. / Line selector switch enables you configure the behavior of the Line/DI Output.
• In the D.I. setting, the button connects the Line/DI Output directly to the Input section thus bypass-
ing the Volume control, Tone controls and Effects Send/Return circuitry. You would use the D.I. set-
ting in a recording or P.A. situation where the mixing technician requires a completely dry signal, as if
it were a DI box, Direct from the Instrument.
• In the Line setting, the button connects the Line/DI Output to the final preamp stage so that the
Volume control, Tone controls and any connected effects all affect the signal. You would use the
Line setting when connecting the Line/DI output to the input of another amp perhaps for added stage
coverage, or to a recording or P.A. mixer where a dry signal is not required.
Tip: For most club PA situations, or for home recording, you would probably prefer the Line setting.
Phones
When a headphone plug is inserted into the PHONES jack, both the built-in speaker and the
Extension Speaker Output jack are disconnected. This permits silent practicing.
Power
The blue Power LED beside the Power switch will illuminate when the unit is on.
Extension Speaker Output (back Panel)
One or two extension speakers can be connected via the Extension Speaker Output jack on the
back panel. The minimum impedance of the external speaker load is 4-ohms (one 4-ohm extension
speaker or two 8-ohm extension speakers). The Extension Speaker jack is wired parallel with the
internal speaker so that the internal speaker (also 4-ohms) will continue to operate when an exten-
sion cabinet is used.
Tip: The power amplifier is electronically, and thermally, protected against unsafe loads and will shut
down (rather than sustain damage) when the speaker load is too low. If a shutdown occurs, discon-
nect the extension speaker and switch the power off. The xm200 will be capable of powering back up
in a few minutes after it cools down.
