Yorkville Sound redefines electronic instrument
amplification with the introduction of the all-new
Traynor K4 keyboard amplifier. An innovative hybrid
tube / solid-state input circuitry makes this combo
amp more than a mere monitor, but part of the
keyboard player's tone pallet.

The heart of the Traynor K4 is the Tube / Solid State
input and Voicing circuitry on the main input
channels. The tube drive can be used to add subtle
warmth and 'fatness' to digital synths and samplers
that often sound 'too pristine' in a mix. It can also
be dialed up to add full-on tube overdrive, creating
unique lead tones and ultra-fat bass sounds. The
tube-drive's gain and lead boost level can be set
from the K4's front panel, and engaged by an
optional footswitch. The Voicing circuit tweaks
channel one's EQ and overall presence for specific
instruments and applications.

This 300-watt system uses a single 12-inch
Eminence speaker to deliver 200-watts of bottom
end in the K4's stereo speaker configuration. Two
additional 50-watt amplifier modules driving a 4 ½­inch Celestion speaker and a 30-watt compression
driver per side handle stereo midrange and high
frequency program.

Designed for the stage, the modified trapezoidal
shape of the K4 allows the amplifier to be used
upright to fill the room or stage, or as a convenient
wedge monitor for the player. The innovative fourth
channel post master input located on the back of
the amplifier allows additional signal to be fed to the
amplifier on stage, without feeding the XLR
balanced DI outputs. Sources like monitor feeds
from the front of house mix, drum machine click
tracks or cue sends can be amplified on stage by the
K4, without feeding channel four to the house mix.
