The
Yorkville
Bass Master xm200 and xm200T
have been designed with the needs of profes-
sional bass guitar players in mind. We believe you will find your
Yorkville
Bass Master xm200
or
xm200T
to be dependable and versatile for years to come.
Tuner Out Jack
This is an instrument-level output ideal for connecting an electronic guitar/bass tuner.
0dB and -6dB Inputs
These are the instrument inputs. Use the 0dB input for bass guitars with normal, passive electron-
ics, like single-coil and humbucking pickups. Use the -6dB for hot or active pickups. These inputs
are
not
intended for connecting more than one instrument at a time.
Mute Button
The Mute button cuts off all audible signals, except for the output to the
Tuner Out
jack. This
enables you to tune your bass without having to adjust any settings on either the bass guitar or
xm200 (
and the audience will not be able to hear you tuning)
.
Limiter
When engaged, the
xm200
’s
Limiter
prevents audible power amplifier clipping (distortion). Unlike input
clip limiters, it does not affect the preamp stage at all. Instead, this
Limiter
ensures that output-stage clip-
ping cannot endanger the speaker or tweeter. In a unique and comprehensive manner, it compares the
output to the available AC power (in technical terms, it reads the DC rail voltage) then, just before output
stage clipping occurs, the
Limiter
reduces signal levels sufficiently to prevent power amp distortion. This
permits the
xm200
to remain cleaner at higher output levels, even when the AC line sags below normal.
Tip: With the Limiter engaged, the only way you can distort your
xm200
is by overdriving the pre-
amp, which is quite acceptable for certain playing styles. This will not harm the drivers as long as the
Limiter remains engaged.
Volume
Set the
Volume
control for the level of sound desired. If unwanted distortion occurs, reduce the
Volume setting and/or the tone control settings (especially bass).
Tone Controls
Each tone control permits a wide range of adjustment. The four overlapping controls cover the
entire audio band. The
Bass
adjusts the level of the lowest note frequencies,
Low Mid
the next
range up from that,
Hi Mid
covers the highest notes and middle harmonics and
Treble
regulates
the upper harmonic range. The center setting on these tone controls is approximately neutral.
Tip: when starting out, it may be good ideas to center all tone controls, and then while you play,
adjust them for the desired sound.
Scoop
The
Scoop
control lets you blend in a unique sound alternative to provide a greatly expanded tonal
range. A setting of 0
provides no
Scoop
and a setting of 10 provides the maximum effect.
Tip: You may find that for best results with
Scoop
at higher settings, the tone controls should be at
settings closer to the center point.
