Always Listening
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’m a Stanford
educated engineer who worked my way through school as a musician. Like all
musicians, I have lugged amplifi ers 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 refl ect my attitudes and life
experiences. I don’t model my designs after other manufacturers’ products.
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 you 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 refl ection
of that story, and has a commitment to support that legacy. Just as the products I created over thirty fi ve years ago are still
telling their story, the products we create today will be talking to us tomorrow.
We’ll be listening,
Robert Gallien

Setup & Maintenance
Packaging:
The carton and packing materials used in
shipping your new product were specifi cally designed
to cushion it from the shocks and vibration that occur
during transport. We suggest that you save the carton
and packing materials for use in shipping.
Transporting:
During transport, do not stack another
cabinet or any additional equipment on top of the
cabinet. The castors are not designed to handle the
weight of more than one cabinet. In situations where
the castors do not roll easily, remove castors and use a
handtruck instead. If traveling with the unit frequently,
we recommend a road case or cover to protect it from
scratches and road wear.
Stacking:
To insure the safe setup of the Neo series
cabinets please follow these basic procedures. Remove
castors from both cabinets before stacking. Never stack
more than two cabinets when in use. Make sure that
interlocking corners are securely seated.
Caution
DO NOT
connect more than one amplifi er to your
speaker enclosure. This will cause damage to your
equipment.
DO NOT
use shielded instrument cables to con-
nect to your speaker enclosure. Use only unshielded
speaker cables of 18 gauge or heavier for speaker
connections.
DO NOT
connect speakers with a total power
handling capacity below the power output rating of
your amplifi er. If your amplifi er is rated at 400 watts
at 4 ohms, then the combined power handling of your
speaker enclosures should be 400 watts RMS or high-
er at 4 ohms. See IMPEDANCE GUIDELINES for
additional info.
DO NOT
connect speakers with a combined total
impedance that is below the minimum rating of
your amplifi er. Doing so may cause damage to
your gear. Using speakers with a total impedance
above the minimum power rating of your amplifi er
is safe.

1) Speakon® Connector:
A high current speaker
connector. Use the provided 4-conductor Speakon®
cable for Horn Bi-Amp operation. Pins 1+ and 1- con-
nect the main amplifi er to the woofers. Pins 2+ and 2-,
connect the horn amplifi er to the tweeter. You may
use a standard 2-conductor Speakon® cable for full
range operation .
2) Mode Switch:
Switches between Horn Bi-Amp
mode and Full Range operation. When using this
cabinet with a Horn Bi-Amp compatible head such as
the 1001RB-II, this switch should be set to BI-AMP.
For operation with all other amplifi ers this switch
should be set to FULLRANGE.
3) Full Range ¼’’ Input Jack:
Using a standard ¼’’
unshielded speaker cable, this input jack provides full
range operation with any bass amplifi er head. Horn Bi-
Amp mode will not work with this jack. Neo cabinets
ship with a removable plug in the 1/4” jack. DO NOT
use tools to remove this plug. It can easily be removed
with your fi ngers.
4) High Range Attenuator:
Adjusts the volume level
of the horn when the cabinet is in Full Range mode.
When in Horn Bi-Amp mode, this control is bypassed
and the horn level is adjusted by using the Tweeter
control on the front panel of the amplifi er.

Impedance Guidelines:
The impedance of your speaker
enclosure is referred to as the Ohm rating. Amplifi ers
connect cabinets in parallel so when combining speaker
enclosures, the impedance or Ohm rating will go down.
8 Ohms + 8 Ohms = 4 Ohms
4 Ohms + 4 Ohms = 2 Ohms
4 Ohms + 8 Ohms = 2.67 Ohms
Note: If you are combining speaker enclosures of
different impedances, the enclosure with the lower
impedance will receive a greater amount of the signal
causing it to be louder than the other cabinet.
Horn Bi-Amp System:
The Neo Series cabinets include a passive crossover for
standard operation or may be used with GK’s unique Horn
Bi-Amp System.
Horn Bi-Amp compatible amplifi ers use an electronic crossover
to split the signal between the main amplifi er and a separate
horn (tweeter) amplifier. The horn amp sends signals
above 5kHz to the horn while the main amplifi er 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 amplifi er. Both signals are delivered to the cabinet via
a sin
gle
Speakon® cable
.
Note:
The 50W horn amplifi er has a fi xed frequency
output of 5kHz and up (high frequencies only). It
will not provide a useable signal to drive a seperate
speaker cabinet.
Note:
To avoid risk of damage to the equipment, do
not use a 4-conductor Speakon® cable with non GK
cabinets. Instead use a 2-conductor Speakon® or
¼” speaker cable.
CAUTION: UNDER NO CIRCUMSTANCES
SHOULD THE WOOFER/MAIN AMP AND
THE 50 WATT HORN AMP BE CONNECTED
TOGETHER!!!
