General Information

The UBX Series is an incredibly compact, versatile, weather resistant, multi- operational family of passive columns featuring Passive UniBeam Technology. The UBX Series comprises of 3 models, the UBX4, UBX8, and UBX16. All UBX models feature state of the art, neodymium 3” full-range transducers and include high-quality, low insertion loss 70/100 V Transform-ers and wall-mount brackets as standard features to simplify integration.

The UBX Series’ new Passive UniBeam Technology utilizes the same complex steering algorithms from our industry leading Iconyx style columns, and imple- ments them in the passive domain. The end result is a fixed, asymmetrical vertical lobe with constant directivity and inherent downward bias that delivers unmatched coverage consistency and speech intel-ligibility.

Heavy-duty aluminum extrusions and covered input pockets deliver an IP64 rating, and extreme salt/chlorine and UV resistance ensure your UBX Series loudspeaker will look as good as it sounds for years to come.

UBX Series Mode Selection Switch

• UBX Series loudspeakers can be installed in many different ways, and our Mode Selection Switch helps facilitate easy selection of the desired operating condi-tions.
• All models feature a traditional Low Impedance mode, and a 70/100 V mode which is ideal for distributed audio systems with high numbers of loudspeakers.
• When operating in Low Impedance Mode, sound qual-ity can be impacted by the power loss associated with long cable runs, and the increase in amplifier load with increasing numbers of loudspeakers.
• When dealing with very long cable runs, or large numbers of loudspeakers, Renkus-Heinz recommends using your UBX Series loudspeaker in 70/100 V mode. When operating in 70/100 V mode, many loudspeak-ers can be installed in parallel on each amplifier chan-nel which can greatly simplify installation of larger systems. Various wattage taps in each voltage range helps to give additional flexibility when deploying large numbers of loudspeakers.
• When operating the Mode Selection Switch please note that the switch does not rotate 360 degrees and there are only 6 positions. Position number 1 is Lo-Z, rotate clock-wise to reach the 5 additional switch po-sitions. Position number 6 is the highest wattage tap, either 60 W (UBX4), or 100 W (UBX8 and UBX16), ro-tate counter-clockwise to return to the other positions. Do not attempt to rotate past position 1 or position 6 or damage will occur.

UBX Series Wiring and Connections

• All UBX Series loudspeakers feature the same style input connections. Input connections are made via a 4 Conductor (2 pair) Barrier strip, the pairs are internally paralleled. Polarity of the barrier strip is indicated in the pocket.
• When connecting a UBX Series loudspeaker to an am-plifier, please connect the positive (+) conductor from the amplifier to the positive (+) barrier strip, and the negative (-) conductor from the amplifier to the nega-tive (-) barrier strip. Many speakers can be connected together on one amplifier channel in parallel or series/parallel using the second internally paralleled barrier strip.
• Pay careful attention to cable type when selecting cabling for your UBX Series loudspeakers. Cabling with too small a cross sectional area relative to impedance load and cable length can result in greater power loss and reductions in sound quality. Under the majority of conditions, 12 AWG cabling will be appropriate, how-ever when cable runs are very long wire gauge should be increased.
• When selecting an amplifier to drive UBX Series loudspeakers, care should be taken to ensure you have appropriate output capability. Please select an amplifier with the appropriate amount of power for the application, typically we recommend at least 3 dB of amplifier headroom. Ensuring that more than enough power is available will prevent driving the system into overdrive reducing possible damage to both the ampli-fier, and loudspeaker.
• When running multiple UBX Series loudspeakers in parallel while in Low Impedance mode, pay careful at-tention to amplifier stability under heavy load. Imped-ance varies by frequency and while nominal imped-ance is a good indicator of a loudspeakers load some frequencies will have lower impedance than what is nominal.

Constant Voltage Operation

UBX4

70 V| 100 V
8 W| 15 W
15 W| 30 W
30 W| 60 W
60 W|

All UBX Series loudspeakers feature a 70/100 V transformer in-side the loudspeaker. This transformer allows many same model UBX loudspeakers to be connected in parallel to a single amplifier channel. The included transformer greatly simplifies installation while reducing cost and complexity of the system.

When connecting UBX Series loudspeakers in Constant Volt-age mode connect the positive (+) conductor of the amplifier, or prior loudspeaker to the positive (+) terminal of the barrier strip and connect the negative (-) conductor of the amplifier, or prior loudspeaker to the negative (-) terminal of the barrier strip. The second paralleled barrier strip inside the input pocket is available for connecting to additional loudspeakers.

UBX8 & UBX16

70 V| 100 V
12.5 W| 25 W
25 W| 50 W
50 W| 100 W
100 W|

When selecting an amplifier for UBX Series loudspeakers in Constant Voltage mode, the available power per channel must be greater than the total of all loudspeaker power taps loaded onto the channel. In order to prevent damage to both the amplifier, and loudspeaker Renkus-Heinz recommends at least a safety margin with at least 3 dB above the total power requirements per chan-nel.

The UBX4 features a 60 W Transformer, and the UBX8 and UBX16 both feature 100 W Transformers. The table to the right details the wattage taps for each transformer type.

Securing Connections Outdoors
All UBX Series loudspeakers include a cover for the input pocket that features a factory-installed Gland-Nut to seal connections from the elements. The Gland-Nut has a cable jacket tolerance range of 0.23” to 0.395” (5.8 mm to 10.0 mm). When installing UBX Series loudspeakers outdoors using the included Gland-Nut cover, please ensure there is a drip loop to prevent water wicking into the pocket.

Wall Mounting UBX Series Loudspeakers

The UBX Series and the Passive UniBeam technol-ogy delivers inherent downward bias, asymmetrical coverage, and constant directivity deliver incredibly consistent coverage, even when plumb to the wall. The UBX Series was designed to be surface-mounted in most applications, and the included wall mount bracket enables safe, simple installation.

As the installer you must insure that the wall or other mounting surface is capable of safely supporting the weight of the array and wall bracket plus the safety margin legally required for your territory. Weights for the UBX Series plus wall bracket is as follows:

• UBX4: 11 lbs./5 kgs.
• UBX8: 17 lbs./7.7 kgs.
• UBX16: 31 lbs./ 14.1 kgs.

UBX Series loudspeakers are too heavy to be sup-ported by gypsum wallboard alone, you must anchor the brackets to structure able to support the weights listed above.

Wall Bracket Instructions

• Disassemble the bracket into the wall and loud-speaker halves by removing the 12 mm bolts and star washers. Remove the three, 6 mm Phillips-head screws from the back of the loudspeaker using a #3 Phillips screwdriver. Be sure to use a #3 Phillips, using a #2 may damage the screws.
• Mount the loudspeaker half of the bracket to the loudspeaker cabinet using the three 6 mm Phillips screws. Use thread locking compound to prevent the screws from loosening.
• The wall half of the bracket is intended to be installed with the bolts facing up. This allows the loudspeaker column to rest on the wall before tightening the nuts and locking splay angles.
• Follow the instructions on the following page for the type of wall to which you are mounting. If you are mounting to a wall type other than those listed on the next page, you must insure that the method you use can safely support the weights listed.

Wooden Stud Wall

• Determine the desired mounting location on the wall. Locate a stud at the desired mounting loca-tion. If there isn’t a stud at your desired mount-ing location, you will need to locally reinforce the wall as the loudspeakers are too heavy to mount directly to gypsum wall board.
• The mounting bracket is centered on the loud-speaker, the center hole of the wall bracket is a good reference point for the center of the mounted loudspeaker.
• Mark and drill pilot holes for the mounting screws.
• Mount the wall bracket to the wall using 1/4 in. diameter x 2 in. long (6 mm dia. x 50 mm long) lag bolts or equivalent. Use at least two mounting screws or bolts.

Masonry Walls

• Determine the desired mounting location on the wall. The mounting bracket is centered on the loudspeaker, the center hole of the wall bracket is a good reference point for the center of the mounted loudspeaker.
• For mounting on concrete, CMU (concrete block) or brick walls, use masonry sleeve anchors, 1/4 in. diameter x 1-1/2 in. long (6 mm dia. x 38 mm long) Red Head Dynabolt or equivalent. Use at least two mounting screws or bolts.
• Mark and drill clearance holes for the mount-ing anchors following the anchor manufacturer’s instructions for diameter and depth.

Mounting the loudspeaker to the bracket

• Slide the loudspeaker and it’s bracket half over the wall bracket, drop down onto the 12 mm bolts, and secure with the nuts and star washers.
• Select the horizontal aiming and tighten the bolts securely to lock the aiming angle in place.
• Connect the audio and your loudspeaker is ready to enjoy.

Optional Pan/Tilt Wall Bracket
The UBX Series was designed to address most in-stallations with surface- mounting plumb to the wall via the included wall bracket. For more extreme applications, Renkus-Heinz developed an optional Pan/Tilt Wall-Bracket, part number W-WALL-UBX-PT.

• Disassemble the bracket into the wall and loudspeaker halves by removing the 12 mm bolts and star washers. Remove the three, 6 mm Phillips-head screws from the back of the loudspeaker using a #3 Phillips screwdriver. Be sure to use a #3 Phillips, using a #2 may dam-age the screws.
• The speaker half of the bracket must first be disassembled into the 2 plates by removing the two 8 mm Socket Head Screws. The inner plate can then be attached to the loudspeaker using a #3 Phillips screwdriver. Be sure to use a #3 Phillips, using a #2 may damage the screws. After the inner plate has been attached to the loudspeaker, the speaker half can be reassembled, and angle set using the two 8 mm Socket Head Screws.
• The wall half of the bracket is intended to be installed with the bolts facing up. This allows the loudspeaker column to rest on the wall before tightening the nuts and locking splay angles.
• The table below details the maximum down angles achievable with optional Pan/Tilt bracket.

UBX Series DSP Settings
While the UBX Series does include an extensive passive crossover network, that network is primarily designed for implimentation of the Passive UniBeam Technology. The crossover does not address voicing, or loudspeaker protection and as such all UBX loudspeakers require active digital signal processing. The tables below include our recommended settings for voicing and protection of UBX Series Loudspeakers.

Design Guidelines for UBX Series
Renkus-Heinz has developed a new coverage generation technology specifically for the UBX Series, Passive UniBeam Technology. Renkus-Heinz’ UniBeam coverage is asymmetrical in nature and has the ability to generate incredibly consistent sound pressure levels and frequency responses in the intended audience areas. In addition to incredible coverage consistency in the intended areas, UniBeam algorithms have extreme off-axis rejection and feature extensive side and gradient lobe suppression, which assist in reducing the effects of reflections and reverberations in any venue.

UniBeam technology has been shaping the sound of Iconyx steerable sound systems for years, and now all the benefits of UniBeam coverage is available for the first time in passive column solutions in the UBX Series. Each model in the series features in extensive passive crossover network that addresses each transducer with a highly specialized passive filter that includes all necessary time, frequency, and amplitude adjustments neces-sary to achieve the UniBeam coverage.

Due to the inherent benefits that Passive UniBeam technology provides, UBX Series models were designed to be surface-mounted plumb to the wall with zero degrees of additional downward angle when used within our recommended mounting heights. All UBX Series models were designed to be mounted at heights of about 6 ft to 8 ft (1.83 m to 2.44m) above finished floor. When mounted at these heights, very consistent coverage should be expected to the distances outlined in the table below

UBX Series Maximum Coverage Guidelines

Model| Low (6 ft / 1.8 m)| High (8 ft / 2.4 m)
UBX4| 30 ft (9.1 m)| 50 ft (15.2 m)
UBX8| 60 ft (18.3 m)| 90 ft (27.4 m)
UBX16| 120 ft (36.6 m)| 160 ft (48.8 m)

The above guidelines are ideal when surface-mounting the UBX Series loudspeakers using the standard wall mount with 0 degrees of inherent down angle. These guidelines are also largely intended for flat, or very gen-tly raked audience planes. For more extreme mounting heights, or non-standard applications we also offer an optional Pan/Tilt Wall Bracket that is detailed on previous pages.

Simulating UBX Series Loudspeakers
If simulation and virtual design work is required when specifying UBX Series loudspeakers, Renkus-Heinz offers GLL files for both EASE Focus 3, and EASE software for design and simulation. The GLL package can be found on our website.
