Congratulations on your purchase of the
KB1000
series amp. The
KB1000
com-
bines a 7-channel stereo line mixer, 4-band EQ, Direct Out box and a stereo / bi-ampable
power amp with crossover into one compact package. Your new amp inherits Carvin’s
rugged DCM power amp technology with features including power amp limiters, high
current
Speakon
™ speaker connectors, 1’ Titanium Drivers for the
KB1010
and the
KB1015
combos, and thermal/short circuit protection. This manual covers the
KB1000
head the
KB1010
and
KB1015
combo amplifiers.
GETTING STARTED QUICKLY
If you are like most players, you probably want to plug in your new amp and
get started playing right away. However, with a full-featured amp like the
KB1000
,
it is important to set it up correctly for optimum results. Before you start, be sure
your amp is plugged into the correct AC voltage.
1.
With the amp turned off, set the
POWER AMP 1 & 2
levels to “5” and set the
MAIN
level to “0” to start. Adjust volume with the
MAIN
level.
2
. Set the
X-OVER
switch to the “
OUT
” position. “
IN
” if you are using the
KB1015
cabinet.
3.
Make sure the
BRIDGE
switch (rear) is set to the “
OUT
”position.
4
. Set the
LOW, LOW MID
,
HI MID
and
HIGH
tone controls to their center “
0
”
position. Adjust later after you are more familiar with the amp.
5.
Plug your keyboard stereo outputs into one of the
INPUT
jack pairs 1 thru 7.
Mono signals should be plugged into the right (
R
) input jack which will be fed
to both
LEFT
and
RIGHT
outputs of the amp. Start with the
INPUT LEVEL
controls at about “3”.
6
. Now, turn the amp
ON
.
7
. With your keyboard output set to 5, start playing. Check to be sure the red
PK
LED
next to the
INPUT LEVEL CONTROL
is not flashing (very dim flashing is
OK) or unwanted distortion will result. Turn down your keyboard’s output level
if your instrument causes input clipping or turn down the
AMP I
or
AMP 2
levels
on the amp. If you hear no sound and the green
SIG LED
does not light, turn
up your keyboard’s output level or check your connection.
8
. Gradually raise the
MAIN POWER AMP
level. Re-adjust according to the desired
volume. Never try to get full power by pushing the
INPUT LEVEL
controls to
maximum while keeping the
AMP 1
&
2
and
MAIN
levels below 5, they should be
set to 10.
9.
Biamping the
KB1015
combo or any large stack requires careful balancing of
the
AMP 1
&
2
controls. These controls power the woofer and 1” Titanium HF
Driver independently. Double check to see that the speakers are plugged
into the correct amp outputs. If the cables are reversed your amp will not
perform correctly.
10.
Need more output? The
KB1000
is a powerful 1000w amp. Adding more speak-
ers is the best way to substantially increase output. Every time you double
your speakers, your acoustic output goes up by a factor of four. This is far
more efficient than trying to add 4 times the power because speakers become
less efficient when driven hard. Bridging your amp into 4 ohms gives you
maximum output. However, the high power of this amp can damage your
speakers. The amp will go into “protect” if loaded below 4 ohms in the bridged
mode. Hopefully, this will help you get started. Have fun exploring the features
and sounds of the
KB1000
.
DESIGNED FOR TOURING
Every
KB1000
is made from heavy-duty 16 gauge steel that is galvanized before
being painted to prevent rust. All internal cabling is neatly tied and harnessed. Every
circuit card is MIL SPEC, double-sided, through-hole plated, fire retardant FR-4 glass
epoxy. This insures that the solder flows on the top, bottom and through each hole
of every component, preventing components from shaking loose. Toroid transformers
are used as they are the engineer’s choice for greater power supply current while
reducing weight and magnetic “hum” fields. Every KB model is made in the USA.
