GK Philosophy

I have never seen the point in doing things the way others have done them. I
also have not been very interested in following the latest fad. I am a Stanford
educated engineer who worked his way through school as a musician. Like
all musicians, I have lugged amplifiers up stairways and into car trunks,
always wondering why these things had to be so heavy, bulky, and hard to
handle.
As I am the principal innovator at GK, our products reflect my attitudes and
life experiences. I don’t model my designs after other manufacturer’s products
(as some of our competitors are proud of reciting). Instead, I believe new and
old problems are best solved with new solutions. Having taken our own path,
GK products enjoy a unique, unmatched sound, allowing the artist using
them every opportunity to make an original statement.
Having supported my products for over thirty years, I have learned from the
story they tell. Gallien-Krueger is a reflection of that story, and has a commit­ment to support that legacy. Just as the products I created thirty years ago are
still telling their story, the products we create today will be talking to us
tomorrow.

If your Neo cabinet did not come with all the items listed above, or if you
encounter problems while setting up your new equipment, please contact
your local dealer, or us as soon as possible at:

Neo Features

Neo Series Cabinets

Neo Series Cabinets are designed to offer the ultimate in sound quality and
stage flexibility. One unique feature are the neodymium speakers, which
maintain high power output at a fraction of the weight of traditional ceramic
speakers. Neodymium speakers also produce a cleaner, smoother response
which reduces ear fatigue.

Horn Management System (HMS):

All Neo cabinets include a passive crossover for standard operation or may be
used with GK’s unique Horn Management System (HMS).

HMS compatible amplifiers use an electronic crossover to split the signal
between the main amplifier and a separate horn (tweeter) amplifier. The
horn amp sends signals above 5kHz to the horn while the main amplifier
sends a full range signal to the woofers. Optionally you can engage the
Woofer High-Cut to to cut signals above 5kHZ from the main amplifier. Both
signals are delivered to the cabinet via a single 4-conductor high current twist­lock cable (Speakon). This arrangement does two things for the sound:

1) Electronic crossovers, can be far superior to the passive crossover found in
full range speaker cabinets, providing a more seamless, accurate sound.

2) With separate power amps for the horn and woofer, the artist can overdrive
the woofer power amp (creating the desired growl) while keeping the horn
amplifier clean and undistorted.

1) Four-Conductor Speakon Connector:

Neo Series cabinets include a Speakon® connector, which allows for HMS
operation when using a 4-conductor Speakon compatible cable available
from GK. Pins 1+ and 1- connect the main amplifier to the woofers in the
cabinet. Pins 2+ and 2-, connect the horn amplifier to the tweeter. When
using a standard 2-conductor Speakon cable, (pins 1+ and 1-) this connec­tor may also be used for full range operation.

2) Mode Switch:

Switches between Horn Bi-Amp (HMS) mode and Full Range operation.
When using this cabinet with an HMS compatible head such as the 1001RB­II, this switch should be set to Bi-Amp. For operation with non HMS amplifi­ers this switch should be set to full range.

3) Full Range ¼'' Input:

Using a standard ¼'' speaker cable, this input jack provides full range
operation with any bass amplifier head. HMS mode will not work with this
jack.

4) High Range Attenuator:

Adjusts the volume level of the horn when the cabinet is in full range mode.
When used in Bi-Amp mode with an HMS compatible amplifier like the
1001RB-II, this control is bypassed and the horn level is adjusted by using the
Tweeter control on the front panel of the amplifier.

Crossover:

Bi-Amp Mode:

When the mode switch is set to Bi-Amp, the passive crossover is bypassed and
the cabinet may be used with an HMS compatible head such as the GK
1001RB-II. Use a 4-conductor, Speakon cable (available from GK) to connect
the head to the cabinet Adjustments to the tweeter and woofer signals are
controlled from the amplifer’s front panel. (the High Range attenuator in the
cabinet is bypassed).

Full Range Mode:

Neo series cabinets are configured for full range operation by setting the mode
switch to Full Range. In this mode you can use either the ¼” or the Speakon
connector for operation. If you are using the Speakon connector, make sure
the amp positive lead is connected to 1+ and the amp negative lead is
connected to 1- on the connector. In this mode the cabinet is setup for full
range operation and the tweeter level is controlled by the High Range control
on the Neo cabinet.
