Yorkville Bass Master xm100
The Yorkville Bass Master xm100 has been created with professional bass players in mind to pro-
duce the highest performance possible from a compact combo. We are confident you will also find
your xm100 bass amplifier to be versatile and dependable for many years to come.
CD / Line In RCA Input Jack
These RCA jacks are provided so that players can connect an external program music source
(*tape or CD) to play along with for performance or practicing.
Tip: Alternatively, a small mixer could be connected here turning the xm100 into a subcompact
PA for low-volume rehearsals.
Hi and Low Input jacks
We have provided two types of inputs. The HI input is for basses that have ‘passive’ pickups and
the LOW input is for ‘active’ pickups (i.e. the bass has a battery-powered preamp built in).
Tip: We do not recommend that you use these jacks to connect and play two instruments at once.
Volume
Set the VOLUME control to the level of sound desired.
Tip: If distortion occurs, reduce the level of this and/or the BASS control.
Bass, Mid and Treble Tone Controls
Each tone control permits a wide, +/-15dB range of adjustment. The three ‘overlapping’ controls
cover the instrument’s entire audio bandwidth.
Tip: If distortion occurs, reducing the Bass setting can often clean it up rather than a reduction of
the Volume setting.
Scoop
The xm100’s Scoop is an extremely helpful tone shaping control. It enables you to contour the
overall depth (bottom end) and high-end presence of your sound.
Line / DI Output (XLR)
This balanced output provides a signal that you can send directly to the mixing console or addi-
tional power amplifiers using a balanced patch cable (a low-impedance mic cable will work). It is
regulated by the Pre EQ / Post EQ selector.
D.I. / Line Selector Button:
This pushbutton enables you to choose what type of signal you are sending out from the Line / D.I.
Output. You can choose D.I. or Line, depending whether you want to have the xm100’s tone con-
trols shape your sound (Pre means no EQ, Post means with EQ).
Tip: If you are running additional amplifiers onstage and want to employ the xm100 as a preamp,
use the Post EQ setting. The Pre EQ setting is sometimes preferred if you are sending your sig-
nal to the mixing console.
Note: With the button In the Pre EQ position, neither the volume nor the tone controls on the
xm100 will affect the Line / DI Output signal. All such adjustments must be made at the mixer.
