Neo Series Bass Combo Amplifi er
Horn Bi-Amp Operation: Bass players have always
liked the growl they get from a slightly overdriven
poweramp. The problem is that growl sounds great
through woofers but will destroy the horn (tweeter).
In a typical fullrange system, there is no way to
get that growl while keeping the definition that
the horn provides. In GK's Horn Bi-Amp system,
an active (electronic) crossover allows a fullrange
signal through to the main (woofer) amplifier,
while only the high frequency portion of the signal
(5kHz and above) is allowed through to the 50 watt
Horn amplifier. There are three primary benefits
to this system over a traditional fullrange system.
•
Significantly reduces the risk of blowing out
the horn's diaphram.
•
More accurate and natural sounding signal
reproduction.
•
Allows you to add as much growl to the woofer
signal as you want while keeping the horn
crystal clear.
Headroom:
Your GK amplifier uses a high
gain, low noise FET input stage with such a large
dynamic range (60v p-p) that even basses with
active electronics may not need to use the input
pad. The benefit to you is a cleaner signal with
less his and much less overall noise.
Effi cency:
The power supply of your amplifi er
uses a unique design which switches between a
low voltage rail for normal output levels and a
high voltage rail to accomodate peak levels. This
much more efficient approach allows us to build
amplifiers with significantly greater output level
at a fraction of the heat and weight. We've also added
a tempaerature sensitive cooling system with a
variable speed fan. Under normal conditions, the
fan will be off or spinning at a low speed. As the
amplifier works harder, the fan speed increases,
maintaining a safe temperature level.
Intelligent Protection Circuitry:
Krueger amplifiers use intelligent protection
cicuitry which constantly monitors for any unsafe
operating conditions such as short circuits or im
properly wired speaker cables. If an unsafe condition
is detected, the output signal is immediately muted
and the power light changes from blue to red. The
amplifier will remain muted until the fault is
removed. If the protection cicuit activates while
playing, turn the amplifier off and check that you
have not exceeded the maximum recommended
load described in this manual.
Direct Out:
electronically balanced DI (Direct Inject) ouput for
connecting to PA and recording consoles.This output is
calibrated for 1.0V (0 dBV) and can be adjusted via
the Level control to match the input sensetivity of
the mixing console. A Ground (Gnd) Lift switch is
included to remove hum and buzz when connecting
to equipment powered by a different ground system.
The Post EQ button allows you to set the Direct Out
signal to either 'Pre' or 'Post' EQ.
Pre EQ:
the Direct Out signal is fed straight from the
input stage and is only effected by the -14dB Pad,
Tuning Mute, and the Direct Out Level control.
Adjustments to the voicing filters or EQ section
will have no effect on the Direct Out signal.
Post EQ:
any changes you make in the voicing filters, EQ
section, Effects Loop (if used) and the Boost will
effect the Direct Out signal going to the mixing
console.
A Final Word: You should now have a thorough
understanding of how your new GK amplifier
works and the advantages it offers in helping to
get 'YOUR' sound. If you have any questions or
