KB/A ™ 30
Full-Range Biamped Combo
When you've got to have it all in a portable, high-powered, full-range amplifier — the KB/A ™ 30 is it!
This amp provides the perfect combination of size, power and features, and is the latest edition to
Peavey's popular KB/A ™ line of amplifiers.
MOBILITY
The KB/A 30 is compact enough to fit in the tightest locations and weighs only 34.3 pounds.
FULL RANGE SOUND
The KB/A 30 offers a special two-way coax speaker system featuring a 10" woofer with a 1"
ferro fluid compression tweeter for exceptional full-range output. The coax design provides the
advantages of a point source system, therefore when you move your head, the center point
doesn't change. The dome tweeter provides a clean extended response that is extremely smooth.
The KB/A 30 cabinet, borrowed from our bass division, offers an isolated, sealed enclosure which
provides optimum bass response.
BIAMPLIFICATION EXPONENTIALLY INCREASES OUTPUT
Unlike any other combo in its class, the KB/A 30 is biamped, which provides dedicated power amps
to both the woofer and tweeter. Biamping greatly increases the sound output as the amplifiers work
much more efficiently. The signal passes through a specially-designed electronic crossover which
feeds the two amplifiers. A 40-watt amp powers the woofer, and a dedicated 10-watt amp powers
the tweeter. Biamping greatly increases the available headroom and enables the KB/A 30 sound out-
put to go beyond what you would expect.
FOUR INPUTS
Channel one is optimized for mic or line input (XLR combo input) and features two-band EQ.
Channel two is optimized for line or acoustic inputs and features a gain switch to better handle
acoustic inputs in addition to the two-band EQ. Channel three is a dedicated line/instrument input
and features two-band EQ. A fourth channel is located on the rear panel and offers a monitor input.
This signal passes only to the amp and is not part of the line output signal. This is handy for click
tracks or other monitoring. You could even have the console monitor signal fed to the amp through
this input giving the KB/A 30 a dual function. An effects insert (send/return) is also provided for
adding your favorite EFX device to the master signal. The variety of inputs provided on the KB/A 30
make it a versatile power packed system.
OUTPUTS
The KB/A 30 offers an XLR balanced line output in addition to a 1/4" effects send jack that can
function as a direct output. Also, the all-important headphone output is placed on the front for easy
access. When the headphone is used, the amplifier signal is automatically muted.
