Orbit Pendant Speaker

OPS1

Installation and Use Manual

Product Description

Thank you for choosing NEAR® Orbit Pendant Loudspeakers.You have purchased

one of the finest pendant loudspeakers available today, the NEAR Model OPS1.

Please familiarize yourself with this product by reading and reviewing the following

descriptions and diagrams.

All NEAR products include similar technical and design aspects that are unique to

the market. NEAR invented and patented the "spiderless" woofer (MLS™), which

features a high-gauss ferrofluid to guide the voice coil through the magnetic field.The

benefits over conventional woofers with cloth spiders are several, including the abil-

ity to constantly adjust voice coil alignment, extend linear excursion, and the most

efficient path for cooling the voice coil.

In addition, the use of metal-alloy cone structures provides several benefits over the

usual paper or plastic cone, such as elimination of cone flex or "break-up" in the

operating ranges, additional thermal path for the voice coil to stay cool, and an

extremely stable cone structure unaffected by the environment.

The NEAR OPS1pendant loudspeaker is a full-range, wide dispersion system pro-

viding overhead sound coverage where ceiling structures are high but the sound

needs to be closer to the audience/listener.An optional cable kit (CK10) suitable for

safety or main drop cable is available.

Settings for both 70V and 100V high-impedance systems, as well as a low-impedance

(16-ohm) position, are provided.Also, a conversion chart for speaker use in 25V sys-

tems is provided in this manual.

All ORBIT models feature a removable snap-lock input connector, providing easy

wire connection for input as well as loop-through to the next speaker.

Installation

If the power level is known, then select it using the front-mounted selector switch

prior to installing the OPS1. See section Selecting Power Levels.

SUSPENSION CABLE ASSEMBLY

1. Screw nuts onto the eye bolts all the way to

the flange.

2. Screw in eye bolts with captured cable sec-

tions in to the three suspension points.

Do not overtighten.

3. Snap loops of free end of cable sections into

quick-snap clip.

4. Connect quick-snap clip to anchor point or

drop cable. Bogen’s CK10 cable kit is suit-

able for use as the drop cable.

SAFETY CABLE

The OPS1includes a safety cable suspension point for extra protection.

The thread of the suspension point is a 1/4-20" x 1/2" thread. Bogen offers a cable

kit as an optional accessory (CK10) that is suitable for use as the safety cable.

IMPORTANT

The anchor point, drop cable, and hardware used to hang the speaker must be able

to support the speaker’s weight under all conditions. IF YOU ARE NOT SURE OF

THE PROPER CAPACITY OF THESE ITEMS TO USE, CONSULT A STRUCTURAL

ENGINEER. Mount only one speaker per supplied quick-snap clip.

Speaker Wiring

Wiring is terminated at a snap-lock input con-

nector. There are two positive and two nega-

tive terminals to accommodate daisy chaining

of speakers in a system. All wiring should be

done prior to installation and then plugged

into the rear of the OPS1.

DAISY CHAINING

The OPS1’s snap-lock input connector allows

for easy daisy chaining of speakers by provid-

ing a second terminal of each polarity. Refer to

the figures for proper wiring for daisy chaining

of terminals.

SPEAKER PHASING

Keep the same polarity terminals wired together to ensure correct phasing. In order

to provide the best possible sound, all of the speakers in a system need to be push-

ing out and pulling in at the same time.

If the connections to one speaker in a system are reversed from the others, that

speaker’s movement will be out of sync with the other speakers.This will result in a

loss of low frequency response and will effect the overall performance of the sys-

tem.

Selecting Power Levels

The front-mounted selector switch is used to

set the appropriate power level or impedance

for your system. Using a small flat-blade screw-

driver, turn the knob until the slot points to the

power level you require.

70V/100V SYSTEMS

Both power setting scales for 70V and 100V sys-

tems are labeled on the speakers. On the 100V

scale, the last position clockwise is marked with

a (not available) symbol. Do not use this posi-

tion in 100V systems.

ΩΩ

SYSTEMS

The fully counterclockwise position of the setting switch is the 16-ohm position.This

setting is suitable for use with low-impedance amplifiers that typically support 4- or

8-ohm speakers.The speaker’s higher, 16-ohm impedance makes it easier to combine

multiple speakers into series - parallel networks while keeping the total system

impedance at a level suitable for low-impedance amplifiers.

25V SYSTEMS

The OPS1will operate on 25V systems, but at

reduced power levels. The chart to the right

shows the conversion from a 70V power setting

to the actual 25V power level.

Accessory

CK10 (CABLE KIT, 10’)

The CK10 is a 10-foot cable with one looped end, a forged eye bolt (with 1/4-20" x

1/2" thread), and an adjustable cable clamp. It is suitable for use as a drop cable or

safety cable.
