Current Output & Bass Response:
When a power amplifier is pushing several speaker cones,
and a high-power transient like a string slap comes along,
the amp has to tap into a large power reserve to maintain
cone control. It’s kind of like grabbing a swing at the
bottom of it’s travel and trying to push it the other way - it
could knock you over. If the amplifier doesn’t have this
ability, the sound is unresponsive and less out front. The
amp loses it’s punch and feel at higher playing levels.
Instead of responding to your every command, the
amplifier simply cuts those transients off, leaving you with
the feeling that something is missing in your sound.

Since most amplifiers have limited output current
capacity, they need “current limiting circuits” to
protect against self-destruction. High-power tran-
sients trigger these circuits, which rob the amplifier of
it’s ability to control speaker cones. This creates a
mushy, unresponsive feel to your sound. The 1001RB
Series has extremely high current capacity, so it doesn’t
need current limiting circuits for over-load protection.

There is nothing in the 1001RB Series power amp to come
between you and your sound except faithful, raw power.

Bi-Amp Sound:
Bass players have always liked the growl they get from
slight overdrive. In GK amps this comes partly from
the boost circuits and partly from the power amp. The
problem is that growl, sounds great through woofers, and
horrible through horns. In the typical full range system
with a passive crossover, there is no way to get growl and
keep the definition that the horn provides. The horn
always has to be turned down. In a Bi-Amp system like
the 1001RB Series, the woofer and the horn, each have
their own power amp, allowing us to get growl in the
woofer only, while keeping the horn sound crystal clear.
Now you can over-drive the woofer as much as you want,
and leave the horn all the way up, keeping the definition it
brings to your sound. Running the 1001RB Series in Bi-
Amp mode through a GK-RBH cabinet, for the first time
allows full access to the benefits of Bi-Amp sound. This is
the reason the 1001RB Series is a Bi-Amp, and it is the
reason you will be able to explore an entirely new territory
of Bass sound.

In addition, running high power amplifiers like the
1001RB Full-Range into cabinets with passively crossed
over horns can cause failure to the horn, attenuator or
protection elements in the speaker cabinet. Running high
power amplifiers as Bi-Amp rigs eliminates these
problems.
