Characteristics of the Backline 110 & 112
The Backline 110/112 is a flexible, user-friendly
state-of-the-art bass amplifier designed to deliver
maximum performance. This is accomplished
through these important features:
High current power supply and power amp
circuitry, for a quick and punchy responce.
Three band active equalization for precise
tone control.
Mid-Contour Shaping
Switchable overdrive channel designed
specifically for bass.
High Current Capability:
When a power amplifier is pushing a speaker cone
and it needs to reproduce a high-power transient like
a string slap, the amp must be able to deliver a high
current pulse to maintain cone control. If the
amplifier can’t do this it simply cuts the transient
off, producing an unresponsive less out front sound.
Creating these high current pulses requires extra
power devices (four times the current required to
deliver its rated power), larger supply capacitors,
and intelligent protection logic. GK is the only bass
amp manufacturer that goes to the trouble and
expense to make this happen and it is a big reason
why GK amplifiers sound louder and cleaner than
other brands at the same power rating.
Active Equalization:
Standard tone controls and graphic equalizers give
you plenty of variation, but they don’t provide what
the instrument really needs. In fact, graphic equaliz-
ers are intended for room equalization and make
poor instrument equalizers. The GK equalizer
reflects 30 years of development and refinement and
is unique to the industry. Each section is a special
circuit optimized to perform a Bass specific job in
its operation range. These sections are wired in
series so they add to one another without creating
unmusical peaks or valleys. The result is an equal-
izer that is easy to use and sounds natural at any
setting.
Contour:
The Contour is based on the same contour circuit as
the 800RB. When engaged, it scoops out the mid
frequencies while emphasizing the lows and
highs.
Overdrive:
The Overdrive channel in your Backline ampli-
fier provides truly distinct distortion and sustain
sounds. It is not a simple clipping circuit but
utilizes FET’s connected in our exclusive
G.I.V.E. configuration. This is an added flexibil-
ity unheard of in this class of product.
The Valve Effect:
As in all GK amplifiers, the Backline amplifier in-
corporates what we call the Valve Effect, or
G.I.V.E(Gate Induced Valve Effect). We use field
effect devices with the gate biased in such a way
that emphasizes the optimum harmonic content of
the signal. Working in concert with our unique Four
Band Active Equalizer, and three stage Voicing Filter
Section, the Valve Effect produces a consistently
pleasing bass tone.
Intelligent Protection Circuitry:
The Backline Series’ protection circuitry con-
stantly monitors for unsafe operating conditions
such as short circuits, miswired speaker cables,
blown speakers, improper ventilation and incor-
rect speaker configurations. In addition, protec-
tion is provided during power up/power down.
If the Backline unit senses any unsafe operating
conditions, the output signal is immediately
muted and the power light changes from Green
to Red. The amplifier will remain muted until
the fault is removed. If the protection circuit
activates while playing, turn the amplifier off
and check the amplifier speaker output connec-
tions. Be sure that you are not exceeding the
maximum recommend load described in this
manual. If the problem persists, contact GK
directly for technical advice.
Enjoy:
You should now have a thorough understanding
of how your new Backline amplifier works and
what advantages it can offer you in getting
“your” sound. We thank you for reading the
Owner’s Manual and wish you the best of times!
