Gear Box Pro Slim Line(SL) Series
Gear Box Pro SLP Series are 2U - 19 rack mount, 3-5/8” deep, high voltage power distribution products. Mounting these units on the rear rack rails behind equipment in the rack saves premium (front) vertical rack space. All SLS Series Products use Torque (Veam style) multi-pin connectors and genuine Neutrik connectors.
SL Series:
Welcome to the Gear Box Pro Ltd. Audio and Power Slim Line family of products. The Gear Box Pro SLP Series is a 2U rack mountable high voltage power distribution product. The model # represents four attributes of the product. SL is an acronym for Slim Line because the metal enclosure is only 3 5/8” or 92mm deep. Mounting on rear rack rails behind equipment in the rack saves premium (front) vertical rack space. All SLS Series Products use Torque (Veam style) multi-pin connectors and genuine Neutrik connectors.
SLP Series:
Within SLP, the P represents power and within the numeric part of the model number the first numeric digit represents the phase (2 = single phase / 3 = three phase) and the next two numeric digits are simply successive product number identifiers.
SLP Series - Special features:
In the line drawing above, you will see that the enclosure is only 3 5/8” or 92mm deep. This is half of the depth of traditional high voltage rack mount power distribution units. All Gear Box Pro power products are constructed with stainless steel enclosures applying Lexan decals instead of the traditional silk screen painted metal. The graphics are laminated underneath the Lexan for a bullet proof product, unlike silk screen that eventually rubs off over time. Genuine HUBBELL electrical components are used for best durability. Our custom hydraulic magnetic breaker meets the most demanding entertainment production requirements. Unlike conventional thermal magnetic breakers, our breakers are less susceptible to temperature and humidity changes which makes the Gear Box products excellent for HOT summer days and COLD outdoor winter production events. These breakers will not only maintain their trip rating, when exposed to extreme temperature and humidity, but they also have a slow trip (curve) rating to handle high in rush currents during amplifier turn on periods.
The SLP-233 provides the highest density power distribution solution. This unit places the outlets on the top and bottom of the enclosure as opposed to exiting the back or rear of the unit, enabling cables to exit at 90 degrees to the power inlet connector. This leaves the back or rear of the unit free of electrical plugs and their cabling obstructing the cabling entering equipment mounted opposite the power bar.
This product is best suited for FOH effects racks.
Series:
Within the SLS, the S represents Speaker for speaker cable / amp rack patching. The numeric digits that follow reflect the number NL8 connectors and if followed by the letter “D”, the NL8’s will have a second NL8 connector wired in parallel.
Note: The SLS Series product can be ordered with a custom length 8 conductor blunt cut cable exiting either the top or bottom of the enclosure for each NL8 group of connectors. This is a great option when wiring to terminal strips on install grade amplifiers. The SLS Series incorporates the Cable Cube wiring of a DISTRO/MATRIX unit in a convenient 2U rack panel. The SLS-2 & 3 place the NL4 full range speaker break out connectors on the front panel with the NL8 and Bi-amp NL4's on the rear panel. The SLS-4 & 4D as well as the SLS-6 & 6D reverse mount the connectors in the enclosure. The SLS-Series can be special ordered w/blunt cut speaker cables exiting the top of the enclosure. If these units require the cable to exit the bottom of the enclosure, the unit can be built loading the components upside down along with the appropriate custom decal. The SLS-4D & 6D has a double or parallel connected pair of NL8 connectors on the front panel. This feature allows a second stage box speaker feeder cable to be patched into the same amplifier channels.

The SLS-2 is a speaker cable splitter/combiner patch panel, primarily for installation amplifier racks. Using Neutrik speaker cable jumpers, the amplifier outputs conveniently patch into the front panel. The outputs on the rear panel then combine channels 1 & 2 into a single NL4 connector providing a Bi-amp output marked 1-2. This is repeated for channels A 3-4, B 1-2 and B 3-4. Each of these Bi-amp NL4 outputs are then combined together in their respective A & B groupings, into a single NL8 connector that can be used to feed an 8 conductor cable with an NL8FC connector allowing flexible patching of 4 full range or two Bi-amp NL4 output connectors in a stage box, by moving a single NL8 connection. An amplifier rack that has four 2 channel amplifiers with Bi-amp NL4 connector outputs when patched into the rear panel, provide all 8 full range amp channels on the front panel.
An alternative use of the SLS-2 is to take an NL8 patch cable from a four channel amplifier that uses an NL8 connector for its output and patch it into one of the SLS-2 rear panel NL8 connectors which then split or fan out into four separate NL4 connectors (Pin 1+ & 1- only) on the front panel for full range speaker cable connectivity.
The SLS-4 & 4D are a speaker cable splitter/combiner patch panels for portable and installation amplifier racks. The SLS-4 is essentially an SLS-2 with the connectors placed on the opposite sides or panels of the enclosure. Using Neutrik speaker cable jumpers, the amplifier outputs conveniently patch into the rear panel. The output or front panel then combines channels 1 & 2 into a single NL4 connector providing a Bi-amp output marked 1-2. This is repeated for channels A 3-4, B 1-2 and B 3-4. Each of these Bi-amp NL4 outputs are then combined together in their respective A & B groupings, into a single NL8 connector that can be used to feed an 8 conductor cable with an NL8FC connector allowing flexible patching of 4 full range or two Bi-amp NL4 output connectors in a stage box, by moving a single NL8 connection. The SLS-4D has a parallel connected NL8 that enables the user to patch a second Stage Box NL8FC cable connection into the same amplifier outputs.
The SLS-6 is a speaker cable splitter/combiner patch panel for portable and installation amplifier racks. The SLS-6 is an SLS-3 with the connectors placed on the opposite sides or panels of the enclosure. The SLS-6 is essentially three Cable Cube DISTRO/MATRIX units in a 2U rack mount panel. Using Neutrik speaker cable jumpers, the amplifier outputs conveniently patch into the rear panel. The output or front panel then combines channels A1 & A2 into a single NL4 connector providing a Bi-amp output marked 1-2. This is repeated for channels A 3-4, B 1-2, B 3-4 C 1-2 & C 3-4. Each of these Bi-amp NL4 outputs are then combined together in their respective A,B & C groupings, into a single NL8 connector that can be used to feed an 8 conductor cable with an NL8FC connector allowing flexible patching of 4 full range or two Bi-amp NL4 output connectors in a stage box, by moving a single NL8 connection. The SLS-6D has a parallel connected NL8 that enables the user to patch a second Stage Box NL8FC cable connection into the same amplifier outputs.
An alternative use of the SLS-6 is to take an NL8 patch cable from a four channel amplifier that has an NL8 output and patch it into one of the front panel NL8 connectors that fan out into four separate NL4 connectors, (Pin 1+ & 1- only) for 4 full range speakers for each group.
